You’re losing money right now. Not from theft or fraud—but from operating expenses you haven’t properly identified, tracked, or managed. For businesses, these day-to-day costs remain the silent profit killers that few leaders truly understand.
I have spent years helping companies cut operating expenses without cutting quality. The pattern is always the same: most businesses track their costs but rarely analyze them. They see the numbers without seeing the opportunities.
Think about it. Your rent, salaries, insurance, and utilities—these ongoing costs flow out so regularly they become background noise. Yet within these routine expenses lie thousands of dollars in potential savings.
A mid-sized tech company I worked with discovered they were spending a significant amount annually on software subscriptions that very few of their staff actively used. Another client found they were paying premium rates on insurance policies that offered redundant coverage. These weren’t careless companies. They simply hadn’t looked at their operating expenses with the right framework.
The difference between businesses that thrive and those that barely survive often comes down to how they handle these everyday costs. Fixed or variable, administrative or selling—each category demands its own approach.
In this guide, we’ll break down every type of operating expense you’ll face. You’ll learn which costs you can safely cut, which deserve investment, and how small changes to your expense management can dramatically improve your bottom line.
Are you ready to turn your operational expenses from a burden into a strategic advantage?

What are Operating Expenses?
Day-to-day costs businesses incur that aren’t directly tied to making products
Includes both fixed expenses (rent, insurance) and variable costs (supplies, utilities)
Critical for accurate financial planning, budgeting, and profit optimization
Operating expenses (OpEx), often called operating expenses, are the necessary costs a business incurs through its normal daily activities. These business expenses are essential for keeping the business’s core operations running but aren’t directly tied to producing goods or services. For businesses making financial decisions, understanding operating expenses provides a clear picture of how much it costs to keep the lights on—literally and figuratively.
Examples of Operating Expenses
Operating expenses appear across all aspects of business operations. Rent payments for office spaces, retail locations, or warehouses typically represent one of the largest operating expenses for many businesses. Commercial real estate costs can account for a substantial portion of total operating expenses for the average business.
Restaurant Expense Allocation: Restaurants spend roughly 85% of revenue on expenses and taxes, yielding about 15% profit.
Staff salaries and benefits form another substantial category of operating expenses. This includes not just base compensation but also payroll taxes, health insurance, retirement contributions, and other benefits. Employee compensation is often the single largest expense category for most businesses.
Utility bills represent a consistent operating expense that can vary significantly based on business type and location. These include electricity, water, heating, air conditioning, and internet services. For manufacturing businesses, utilities might account for a larger share of operating expenses than for service-based companies in office settings.
Other common examples of operating expenses include:
Office supplies and equipment
Professional services (accounting, legal fees)
Business insurance premiums
Marketing and advertising costs
Travel and entertainment expenses
Software subscriptions and technology services
Types of Operating Expenses, including Fixed and Variable Costs
Operating expenses can be categorized in several ways, but the most fundamental distinction is between fixed and variable costs. Understanding the balance between these two types helps businesses make more informed decisions about scaling operations, setting prices, and planning for financial stability.
Fixed costs provide stability but can become burdensome during slow periods. Variable costs offer flexibility but can rise unexpectedly during growth phases. Most businesses aim for an optimal mix that provides both stability and adaptability. Companies with a balanced approach to fixed and variable expenses have demonstrated better financial resilience during economic downturns.
The ratio between fixed and variable costs also impacts a company’s break-even point—the level of sales needed to cover all expenses. Businesses with higher fixed costs typically have higher break-even points, which can create more financial risk but also greater potential for gross profit once that threshold is crossed.
1. Understanding Fixed Costs and Operating Expenses
Fixed operating expenses remain constant regardless of business activity levels. These costs don’t fluctuate with production volume or sales and must be paid regardless of how the business is performing. This predictability makes them easier to budget for but also creates financial obligations that continue even during slow periods.
Commercial lease agreements represent a classic fixed expense. Whether a retail store serves a few customers or many in a day, the monthly rent remains the same. Similarly, insurance premiums for business liability, property insurance, and workers’ compensation typically involve annual contracts with fixed payment schedules. Loan payments for business equipment or property also fall into this category with predetermined payment amounts and schedules.
Many businesses underestimate the impact of fixed expenses when planning for growth or contraction. When fixed costs make up a large portion of total operating expenses, a company has higher operating leverage—meaning small changes in revenue can produce significant changes in operating income. Businesses with high fixed costs experience greater profit swings than those with predominantly variable cost structures when revenue fluctuates.
Managing Fixed Operating Expenses
Effective management of fixed expenses often involves negotiating favorable long-term contracts during periods of strength. Many companies seek to convert fixed expenses to variable ones where possible—for example, by using cloud-based services with usage-based pricing instead of purchasing server hardware outright. Businesses that strategically convert a portion of their fixed IT costs to variable models can improve their financial flexibility and eliminate excess spending.
2. Variable Operating Expenses
Variable operating expenses fluctuate in direct proportion to business activity. As production volumes increase, these costs rise; as activity decreases, these expenses naturally fall. This natural scaling provides financial flexibility but can make budgeting more challenging and unpredictable.
Small Business Cost Breakdown: Small businesses typically spend around 90% of revenue on total costs (expenses and taxes), with 95% being poor and 80% considered good.
Raw materials and direct supplies represent the most obvious variable costs. For a coffee shop, the cost of coffee beans, milk, and cups rises directly with customer volume. Sales commissions exemplify variable expenses in the service sector—more sales mean higher commission payouts, but these increased costs come with proportionally higher revenue. Even some cogs operating expenses can be considered variable.
Utility expenses often have both fixed and variable components. The base connection fee for electricity remains constant, while the actual usage charges vary with consumption. Shipping and delivery costs similarly scale with order volume, making them primarily direct expenses.
Analyzing Variable Cost Patterns
Understanding variable cost patterns helps businesses forecast expenses more accurately. While truly variable costs should scale linearly with activity, many expenses exhibit “step” patterns—remaining stable within certain activity ranges before jumping to a higher level. For example, a business might maintain the same customer service team until reaching a threshold where additional staff becomes necessary.
Companies that effectively track and manage the costs incurred maintain higher profit margins than competitors who treat these expenses as completely unpredictable. It is recommended to establish clear variable cost metrics—such as cost per unit, cost per customer, or cost per transaction—and monitor these ratios over time to identify inefficiencies or changes in cost behavior.
3. Semi-Variable Operating Expenses
Semi-variable expenses (also called mixed costs) contain both fixed and variable components. Understanding these hybrid costs is crucial for accurate financial planning since they don’t respond to activity changes in a simple, linear fashion.
Sales staff compensation illustrates this category well. A typical structure includes a base salary (fixed) plus commission (variable). Similarly, equipment maintenance often includes scheduled preventive maintenance (fixed) plus repairs based on usage (variable). Communication expenses, like cell phone plans with base rates and overage charges, represent another common semi-variable expense. Employee salaries are often a major part of this category.
For accurate budgeting, businesses should separate the fixed and variable components of these expenses. This process, called cost behavior analysis, helps predict how total costs will change with different activity levels. Companies that properly segment semi-variable costs achieve more accurate budget forecasts than those treating these expenses as purely fixed or variable.
4. Discretionary Operating Expenses
Discretionary expenses represent costs that management can adjust or eliminate in the short term without immediately impacting core operations. These expenses provide financial flexibility during economic downturns or cash flow constraints.
Employee training programs, research and development initiatives, and charitable contributions typically fall into this category. Marketing and advertising budgets, while essential for long-term growth, can often be adjusted in the short term without immediate operational impact. Maintenance expenses beyond what’s immediately necessary for equipment function can also be delayed when needed.
During economic downturns, companies that strategically cut discretionary expenses rather than making across-the-board reductions tend to recover faster when economic conditions improve. The key distinction is preserving investments in areas directly tied to competitive advantage while trimming truly discretionary costs.
5. Non-Operating Expenses
While not technically operating expenses, non-operating costs often appear alongside OpEx on financial statements and warrant mention for clarity. These costs relate to activities outside a company’s core operations. To deepen your understanding of these important financial elements, exploring what constitutes non-operating expenses and their impact on business performance is essential. For a comprehensive explanation, check out our detailed post on Understanding Non-Operating Expenses. This resource provides valuable insights into how these expenses influence your overall financial health and strategic decisions.
Interest expenses on business loans represent the most common example. These financial costs don’t directly relate to producing goods or services but significantly impact overall profitability. Similarly, losses from selling assets, legal settlements from past events, and restructuring costs fall outside normal operations.
The distinction matters for financial analysis. When evaluating a company’s operational efficiency, analysts typically exclude these costs to focus on how well the business performs its core functions. According to financial accounting standards, separating operating from non-operating expenses provides stakeholders with a clearer picture of sustainable business performance.
What are the Main Operating Expenses, Excluding Capital Expenditures and Goods Sold?
The largest operating expenses vary by industry, but certain categories consistently rank among the most significant for most businesses.
Personnel costs, including labor costs, typically represent the largest operating expense for service-based businesses. This includes salaries, benefits, payroll taxes, and training costs. For retail and manufacturing businesses, this percentage is typically lower but still substantial.
Facility costs—including occupancy costs like rent, utilities, maintenance, and property taxes—frequently rank second for businesses with physical locations. Technology costs have grown significantly, now representing a large part of operating budgets for most companies, covering software subscriptions, hardware, IT support, and digital infrastructure.
Construction Industry Costs: In construction, around 95% of revenue goes to expenses and taxes, leaving about 5% profit.
Marketing and sales expenses typically account for a notable share of operating budgets, though this varies dramatically by industry. Consumer-focused businesses often spend more heavily in this category than B2B companies.
Retail Sector Spending: Retail businesses often allocate about 95% of revenue to expenses and taxes.
Notably, certain expenses are explicitly excluded from operating expenses on financial statements. Capital expenditures for long-term assets appear on the balance sheet rather than the income statement. Cost of goods sold (COGS)—direct costs attributable to the production of goods sold—appear separately on income statements. Dividend payments to shareholders and stock repurchases represent financial transactions rather than operating expenses. To further understand the financial distinctions and implications, its helpful to explore the various types of capital expenditures. These investments in long-term assets play a crucial role in shaping a companys growth strategy and overall financial health, separate from daily operating expenses.
For businesses seeking to understand their expense structure, the operating expense ratio (OER) provides a useful metric, comparing operating expenses to revenue. Healthy OERs can range widely. Companies with significantly higher ratios than industry peers may have opportunities for cost optimization.
Operating Expenses Breakdown: Understanding Operating Costs
Operating expenses fall into specific categories like administrative, selling, and maintenance costs
Proper classification helps businesses analyze expense necessity and impact on profitability
Understanding these categories enables better financial decision-making and budget optimization
Operating expenses represent the day-to-day costs that keep a business running. Breaking them down into specific categories creates a clearer picture of where money flows within your organization. This breakdown of operational expenses serves as the foundation for cost analysis, budgeting, and financial planning.
When classifying operating expenses, businesses typically use several standard categories. These classifications help track spending patterns, identify areas for potential cost reduction, and make informed decisions about resource allocation. Let’s explore each major category in detail.
Administrative Expenses
Administrative expenses cover the costs related to general business operations that don’t directly generate revenue but are essential for the company’s functioning. These indirect costs support the organizational infrastructure and the business’s operational activities.
Common administrative expenses include office supplies, management and administrative staff salaries, legal and professional fees, insurance premiums, and utilities. For example, the salary of your CFO, the cost of accounting software, or fees paid to your legal counsel all fall under this category. These expenses remain relatively constant regardless of sales volume.
For small businesses, typical monthly administrative costs can include rent, utilities, and insurance. These costs form the backbone of business operations but often present opportunities for optimization.
When analyzing administrative expenses, consider whether each cost is essential for business operations. Some questions to ask: Could certain administrative functions be automated or outsourced? Are there subscription services that overlap in functionality? Could you negotiate better terms with vendors? This critical analysis helps identify potential areas for cost reduction without affecting core business functions.
Selling and Marketing Expenses and Advertising Costs
Selling and marketing expenses are costs directly related to promoting products or services and generating sales. These expenses support revenue-generating activities and help build brand awareness and customer relationships.
This category includes advertising costs across various channels, marketing campaign expenses, sales team salaries and commissions, trade show participation fees, and promotional materials. For example, the cost of running Google Ads, hiring a content marketing agency, or paying your sales team’s commissions all fall under selling expenses.
Digital marketing expenses for small businesses can vary depending on strategy and scale. Salaries for sales and marketing staff can also fluctuate based on team size and roles.
Analyzing Marketing ROI
Each marketing and selling expense should be evaluated based on its return on investment (ROI). Track metrics like customer acquisition cost (CAC), conversion rates, and lifetime value of customers (LTV) to determine which marketing channels deliver the best results. This data-driven approach helps optimize marketing spend by focusing resources on the most effective channels.
Research and Development Expenses
Research and development (R&D) expenses represent costs associated with innovation, product development, and improving existing offerings. These expenses are particularly significant for technology, pharmaceutical, and manufacturing companies.
R&D expenses typically include research personnel salaries, laboratory equipment and supplies, testing costs, patent applications, and prototype development. For software companies, this might include developer salaries and costs associated with testing new features.
The treatment of R&D expenses can vary. While some R&D costs are recorded as operating expenses, others might be capitalized as assets on the company’s balance sheet if they meet specific criteria. This distinction is important for financial reporting and tax purposes.
Businesses should regularly evaluate their R&D spending against outcomes. Are innovation efforts leading to marketable products or improved efficiency? What percentage of R&D projects result in successful market launches? This analysis helps ensure R&D budgets are allocated effectively and align with the company’s strategic goals.
Facility and Occupancy Expenses
Facility and occupancy expenses cover costs related to physical business spaces and their maintenance. These expenses are necessary for providing a functional workspace for employees and, in some cases, serving customers.
This category includes rent or mortgage payments, property taxes, building maintenance and repairs, cleaning services, security, and utilities. For businesses with multiple locations, these costs can represent a significant portion of operating expenses.
In the current business environment, many companies are reassessing their facility needs. The rise of remote and hybrid work models has led some businesses to reduce their physical footprint, resulting in significant cost savings. Others are investing in workspace redesigns to enhance collaboration and employee satisfaction.
When analyzing facility expenses, consider space utilization efficiency. Are you paying for more space than you need? Could you negotiate better lease terms? Would a different location reduce costs while maintaining accessibility? These questions help optimize facility expenses without compromising operational effectiveness.
Technology and Equipment Expenses
Technology and equipment expenses cover costs related to the hardware, software, and technical infrastructure that support business operations. As businesses become increasingly digital, these operating expenditures represent a growing portion of operating budgets.
This category includes computer hardware and software purchases or subscriptions, IT support services, telecommunications, data storage and processing, and equipment maintenance. For example, costs associated with your CRM system, company laptops, and cloud storage services fall under this category.
Technology expenses often present a mix of fixed and variable components. Software subscriptions typically involve fixed monthly fees, while data processing costs might vary based on usage. Understanding this distinction helps with accurate budgeting and forecasting.
When evaluating technology expenses, consider the total cost of ownership (TCO) rather than just the initial purchase price. TCO includes maintenance, training, upgrades, and eventual replacement costs. Also assess whether technology investments are delivering expected productivity improvements or competitive advantages.
How to Classify Operating Expenses on an Income Statement?
Proper classification of operating expenses requires a systematic approach that aligns with accounting standards and business needs. Following these guidelines ensures consistency and accuracy in the company’s income statement.
Start by establishing clear categories that make sense for your business. While standard categories like those discussed above provide a good framework, you might need industry-specific classifications. For example, healthcare organizations might have a separate category for medical supplies, while restaurants would track food costs separately.
Next, create a chart of accounts that defines each expense category and subcategory. This structured approach ensures consistent classification across your organization. Modern accounting software often includes predefined charts of accounts that you can customize to fit your business.
Accounting Treatment Considerations
From an accounting perspective, operating expenses are recorded on the income statement for the period in which they occur. Unlike capital expenses, which are capitalized and depreciated over time, operating expenses are fully deducted in the current period.
When classifying expenses, it’s important to distinguish between operating and non-operating items. Non-operating expenses, such as interest payments or losses on asset sales, should be categorized separately as they don’t relate to core business operations.
For public companies, consistent classification is particularly important for financial reporting. The Securities and Exchange Commission (SEC) and Generally Accepted Accounting Principles (GAAP) provide guidelines for expense categorization to ensure transparency and comparability across financial statements.
Analyzing the Purpose and Necessity of Expenses
Beyond classification, businesses should regularly analyze the purpose and necessity of each expense category. This critical examination helps identify opportunities for cost optimization without compromising operational effectiveness.
Start by asking fundamental questions about each expense: Does this expense directly support our business objectives? Is the cost proportional to the value it delivers? Could we achieve the same outcome at a lower cost? This questioning approach helps distinguish between essential expenses and those that might be reduced or eliminated from all your operating expenses.
For administrative expenses, evaluate whether each function could be streamlined, automated, or outsourced. For selling expenses, analyze the ROI of different marketing channels to focus spending on the most effective approaches. For technology expenses, assess whether current solutions provide value relative to their cost.
Regular expense reviews should become part of your financial management routine. Many businesses conduct quarterly expense reviews to identify trends, adjust budgets, and implement cost-saving measures. This proactive approach helps maintain financial health and competitive positioning. This is particularly true in industries like hospitality, where leaders are focusing on controlling costs such as labor, maintenance, and administrative overhead to maintain profitability.
Understanding the detailed breakdown of operating expenses provides the foundation for effective cost management. By classifying expenses appropriately and regularly analyzing their purpose and necessity, businesses can make informed decisions about resource allocation and identify opportunities for efficiency improvements. This knowledge directly impacts profitability and supports long-term business sustainability.
Managing Business Costs: Benefits of Understanding Operating Expenses for Financial Health
Detailed knowledge of operating expenses directly improves financial decision-making
Clear understanding leads to more accurate forecasting and budgeting
Companies with strong expense management typically see better profit margins
Benefit 1: Improved Budget Management
Operating expenses form the backbone of any business budget. When executives understand these costs in detail, they can make more informed decisions about resource allocation. CFOs who closely track operating expenses can identify spending patterns that might otherwise go unnoticed. This awareness allows for strategic redistribution of funds toward higher-performing areas of the business.
A comprehensive understanding of common business expenses enables finance teams to build more precise budget models. The typical business budget contains hundreds of line items, many of which represent operating expenses that fluctuate based on business conditions. Companies that track these expenses with precision can adapt quickly to changing market conditions. For example, a retail business that carefully monitors its utility costs can adjust staffing and store hours during periods of high energy prices to maintain profitability.
Budget flexibility stems directly from operating expense knowledge. When finance leaders can clearly differentiate between fixed, variable, and semi-variable costs, they can identify which expenses can be adjusted in response to revenue changes. Companies that maintain flexible budgets based on detailed expense tracking tend to recover from economic downturns faster than those with rigid budgeting processes.
Cost Control Mechanisms
Effective budget management requires implementing specific cost control mechanisms. These include:
Regular expense variance analysis (comparing actual vs. budgeted expenses)
Zero-based budgeting for discretionary operating expenses
Departmental spending accountability systems
Monthly expense review meetings with department heads
These mechanisms work best when supported by detailed operating expense data. For instance, a manufacturing company that implemented zero-based budgeting for its administrative expenses discovered unnecessary software subscriptions that employees had signed up for but weren’t actively using.
Benefit 2: Enhanced Financial Performance
Understanding operating expenses directly impacts financial performance metrics. When executives have clear visibility into cost structures, they can make targeted interventions to improve profitability and gross profit. A detailed breakdown of operating expenses reveals opportunities for cost reduction that preserve or enhance value delivery.
Strategic cost management begins with expense categorization and prioritization. Not all operating expenses contribute equally to business success. By analyzing the relationship between specific expenses and revenue generation, companies can identify which costs deliver the highest return. For example, a professional services firm that analyzed its operating expenses discovered that investments in employee training yielded a significant return through improved productivity and client satisfaction.
This principle applies perfectly to operating expense management. Financial leaders must focus not just on reducing costs but on optimizing the value derived from every dollar spent. Companies that adopt this value-focused approach to expense management consistently outperform their peers in profitability metrics.
Setting Realistic Financial Targets
Operating expense knowledge enables more realistic financial goal-setting. When executives understand the true cost structure of their business, they can set achievable targets that motivate teams without creating unrealistic expectations. This balance is critical for maintaining both operational effectiveness and employee morale.
Financial targets should account for:
Fixed cost obligations
Seasonal variations in variable expenses
Industry benchmarks for expense ratios
Growth-related cost increases
Companies that set targets without this foundation often face a cycle of missed projections, hasty cost-cutting, and declining performance. In contrast, businesses with strong operating expense understanding set achievable targets that build credibility with investors and employees alike.
Benefit 3: Improved Cash Flow Management
Cash flow problems sink more businesses than poor profitability. Understanding operating expenses directly improves cash flow management by helping executives anticipate outflows and plan accordingly. This visibility is especially critical for businesses with seasonal revenue patterns or rapid growth trajectories.
Operating expense analysis reveals cash flow optimization opportunities. For example, a detailed review might uncover opportunities to:
Renegotiate payment terms with vendors
Adjust billing cycles to better match expense timing
Identify unnecessary subscriptions or services
Implement just-in-time inventory systems to reduce carrying costs
A mid-sized technology company that conducted a comprehensive operating expense review discovered they were paying for office space in excess of their actual needs. By subleasing the extra space, they generated additional monthly cash flow that funded critical growth initiatives.
Cash Flow Forecasting Accuracy
Precise operating expense data dramatically improves cash flow forecasting. When finance teams understand not just how much they spend but when those expenses hit their accounts, they can build more accurate cash flow models and improve the company’s financial health.
This insight from Drucker remains as relevant today as ever. Operating expenses directly impact cash flow, and businesses that optimize these expenses enjoy greater financial stability. Companies with strong cash flow management can weather economic downturns, invest opportunistically, and avoid costly emergency financing.
Benefit 4: Strategic Decision Support
Operating expense knowledge provides essential context for strategic decisions. When executives consider expansion, new product development, or market entry, detailed expense data helps them evaluate these opportunities more accurately.
A thorough understanding of operating expenses supports:
Make-vs-buy decisions
Market entry evaluations
Pricing strategy development
Investment prioritization
For example, a food manufacturer considering expansion into a new product line used detailed operating expense data from its existing operations to build an accurate cost model for the new venture. This analysis revealed that the fixed costs associated with the expansion would require much higher sales volumes than initially projected to reach profitability.
Competitive Advantage Through Cost Structure
Companies with superior operating expense knowledge gain competitive advantages. They can:
Price products more strategically
Identify areas where competitors with high operating costs are likely struggling
Invest in efficiency improvements with the highest returns
Make faster decisions based on better information
In competitive markets, this advantage compounds over time. While competitors make decisions based on incomplete cost information, businesses with strong operating expense management can target their investments precisely where they’ll create the most value.
Benefit 5: Risk Management and Business Continuity
Operating expense knowledge directly supports risk management. When executives understand their cost structure in detail, they can develop more effective contingency plans for various scenarios. This preparation improves business resilience in the face of economic downturns, supply chain disruptions, or other challenges.
Detailed operating expense understanding enables companies to:
Identify areas of excessive cost concentration
Develop alternative supplier relationships
Create scenario-based contingency plans
Maintain appropriate cash reserves
During recent economic disruptions, companies with strong operating expense management were able to adapt more quickly than their peers. They knew exactly which expenses could be reduced without damaging core capabilities and which investments needed to continue despite financial pressures.
Cost Structure Flexibility
The most resilient businesses maintain flexibility in their cost structures. They understand which operating expenses can scale up or down based on business conditions and deliberately avoid excessive fixed cost commitments. This flexibility acts as a built-in shock absorber during difficult periods.
For example, a business services firm with detailed operating expense tracking was able to rapidly shift a large portion of its workforce to remote work during the pandemic. Because they had previously analyzed their facility costs and technology infrastructure, they quickly identified which expenses could be reduced and which required immediate investment to support the transition.
Implementation Considerations
To fully realize the benefits of operating expense understanding, companies need systematic approaches to expense tracking and analysis. This requires both technological solutions and organizational processes that support expense visibility.
Effective operating expense management systems include:
Detailed expense categorization frameworks
Regular expense review meetings
Variance analysis protocols
Clear accountability for expense management
Technology solutions that provide real-time expense data
The most successful implementations balance detail with usability. While comprehensive expense data is valuable, systems that create excessive administrative burden can become counterproductive. Leading organizations focus on capturing the most decision-relevant expense information while automating data collection wherever possible.
How to Analyze Operating Expenses
Financial ratios provide quick insights into cost performance and efficiency
Regular expense analysis helps identify waste and optimization opportunities
Benchmarking against industry standards reveals competitive positioning
Setting Up Your Operating Expense Analysis Framework
The first step to analyzing operating expenses effectively is establishing a structured framework. Begin by categorizing all expenses into fixed, variable, and semi-variable costs. This classification makes patterns more visible and helps identify which expenses respond to changes in business activity.
A good analysis framework requires clean, accessible data. Pull expense records from your accounting system and organize them in a spreadsheet or financial analysis software. Try to include enough data to spot seasonal trends and long-term patterns. Group similar expenses together (utilities, rent, insurance, etc.) and create subtotals for each category to understand which areas consume the most resources.
Expense Categorization Best Practices
When building your analysis framework, be consistent with your categorization. Create clear definitions for each expense type and apply them uniformly. For example, decide whether software subscriptions belong in “Technology” or “Administrative” expenses and stick with that decision.
Consider creating both functional categories (marketing, operations, administration) and behavioral categories (fixed, variable). This dual categorization allows for multiple analysis angles. Also, assign responsibility centers to each expense, connecting costs to the departments or managers who control them.
Applying Financial Ratios for Operating Expense Evaluation
Financial ratios provide powerful tools for understanding operating expenses in context. The Operating Expense Ratio (OER) measures operating expenses as a percentage of revenue, offering a quick assessment of operational efficiency. Calculate it by dividing total operating expenses by total revenue. A higher operating expense ratio may indicate inefficiencies.
Another valuable metric is the Operating Expense to Sales ratio, which shows how much of each sales dollar goes toward operating costs. A declining ratio over time typically indicates improving operational efficiency. For service businesses, the Cost-to-Income ratio offers similar insights.
Key Operating Expenses by Industry
-Real Estate OER: A “good” operating expense ratio in real estate is between 60% and 80%.
-Farming OER: AgDirect states that a healthy operating expense ratio for farms is around 65%, with corn and soybean typical at 70–75%, sometimes up to 80%.
-Multifamily Property OER: Multifamily property OER typically ranges from 35% to 45%.
-Office Building OER: Office building operating expense ratios generally sit between 35% and 55%.
-Retail Property OER: Retail property OER often falls between 20% and 30%.
-Hospitality OER: Hospitality (hotels and motels) usually have OER in the 50%–65%.
-Average Retail OER: The average retail industry OpEx ratio is about 65%.
-Commercial Real Estate Benchmarks: In commercial real estate: industrial properties have OER between 15% and 25%.
Expense-to-Revenue Relationship Analysis
Beyond basic ratios, examine how expenses change relative to revenue growth. Calculate the incremental expense ratio by dividing the change in expenses by the change in revenue between two periods. This can suggest good operational leverage.
For deeper insights, plot expenses against revenue over multiple periods to visualize the relationship. A linear relationship suggests consistent variable costs, while a curved line might indicate economies of scale or cost control issues at certain revenue levels.
Performing Regular Expense Review Cycles
Consistent review cycles are essential for spotting inefficiencies and controlling costs. Set up monthly, quarterly, and annual review schedules, each with different analysis depths. Monthly reviews should focus on identifying unusual variances and immediate issues. Quarterly reviews can examine trends and progress on cost-saving initiatives. Annual reviews should include comprehensive analysis and strategic planning.
During these reviews, use variance analysis to compare actual expenses against budgets or forecasts. Investigate significant variances, both positive and negative, to understand their causes. This process helps identify both problems and successes in cost management.
Regular reviews through spend analysis—collecting, cleansing, classifying, and analyzing spending data—are proven methods to spot inefficiencies and identify cost-saving opportunities.
Creating Actionable Insights From Reviews
The goal of expense reviews isn’t just to collect data—it’s to generate actionable insights. For each significant finding, document potential actions. If utility costs are rising unexpectedly, investigate energy efficiency measures. If travel expenses are increasing, consider implementing stricter approval processes or virtual meeting alternatives.
Prioritize findings based on financial impact and implementation ease. Quick wins with high impact should be addressed first, while more complex issues might require longer-term planning. Document all insights and actions in a tracking system to ensure follow-through.
Benchmarking Against Industry Standards to Calculate Operating Expenses
Comparing your operating expenses to industry benchmarks helps assess your competitive position. Industry associations, consulting firms, and financial databases offer benchmark data for various sectors. Key metrics to compare include Operating Expense Ratio, Cost of Goods Sold percentage, and specific expense categories like marketing as a percentage of revenue.
When benchmarking, make sure you’re comparing against businesses of similar size and business model. A small retailer shouldn’t compare their expenses directly to large corporations. Look for trends rather than absolute numbers—if your expenses are trending down while industry expenses rise, you’re likely improving your competitive position.
Internal Benchmarking Across Business Units
Beyond external benchmarking, compare performance across your own business units or locations. This internal benchmarking reveals best practices and problem areas within your organization. If one location operates with significantly lower expenses than others, investigate what they’re doing differently.
Create standardized expense metrics for comparing units of different sizes, such as expenses per customer, per square foot, or per employee. These normalized metrics enable fair comparisons despite size differences. Use the findings to spread successful cost management practices throughout the organization.
Implementing Advanced Analysis Techniques
As your analysis capabilities mature, implement more sophisticated techniques. Cost driver analysis identifies the underlying factors that influence expense levels. For example, customer service costs might be driven by call volume, which itself could be driven by product quality issues or unclear instructions. The total operating expenses incurred can often be traced back to a few key drivers.
Trend analysis examines how expenses change over time, helping forecast future costs and identify seasonal patterns. Plot key expense categories over multiple years to spot long-term trends that might not be visible in shorter time frames.
Organizations are increasingly using process optimization, automation, and advanced analytics (including AI) to reduce operating expenses and improve efficiency. These technologies can both assist in analysis and directly reduce costs.
Predictive Analysis for Future Planning
Use historical expense data to build predictive models for future costs. These models can account for factors like expected business growth, inflation, and planned initiatives. Predictive analysis helps with budgeting and allows you to test “what-if” scenarios before making decisions.
For example, you might model how an increase in production would affect variable costs, or how implementing a new technology might reduce labor expenses over time. These projections help inform strategic planning and prepare for future challenges.
Taking Action Based on Analysis Findings
Analysis only creates value when it leads to action. Develop a systematic approach for converting findings into improvements. Start by prioritizing opportunities based on potential impact and feasibility. Create specific, measurable goals for cost reduction or efficiency improvement in each target area.
Form cross-functional teams to address complex issues, bringing together expertise from finance, operations, and relevant departments. Set clear timelines and accountability for implementing changes, and track progress regularly. Celebrate and communicate successes to build momentum for continuous improvement.
Building a Cost-Conscious Culture
Lasting expense management requires building a cost-conscious culture throughout the organization. Make expense data transparent and accessible to managers. Provide training on financial concepts and cost management techniques. Recognize and reward cost-saving initiatives from employees at all levels.
Consider implementing incentive systems that share the benefits of cost savings with the teams responsible for achieving them. This alignment of interests helps ensure everyone contributes to operational efficiency, not just the finance team.
How Operating Expenses Affect Business Success
Operating expenses directly impact your bottom line – every dollar saved increases profits
Effective expense management creates competitive advantage through better pricing or higher margins
Systematic expense control supports sustainable growth and financial stability
Operating expenses form the financial backbone of your business operations. They directly influence your profitability by determining how much of your revenue becomes actual profit. When you manage operating expenses effectively, you create a clear path to business success through improved margins, competitive pricing, and financial stability.
Let’s explore how to systematically manage these expenses to boost your business performance.
Step #1: Conduct Regular Expense Audits
Regular expense audits help you find and eliminate unnecessary costs that drain your resources. These audits require detailed examination of all business expenses to identify patterns, anomalies, and opportunities for savings.
Setting Up Your Expense Audit Process
Start by gathering comprehensive expense data from the past several months. Organize this information by expense category, department, and time period. This organization helps you spot trends and outliers that might indicate waste or inefficiency. For example, if marketing expenses suddenly increased without a corresponding rise in leads or sales, this warrants investigation.
Create a structured audit schedule—quarterly for major expense categories and monthly for variable costs that fluctuate significantly. During each audit, compare current expenses against historical data, budgets, and industry benchmarks to identify areas that need attention.
Creating an Expense Reduction Action Plan
After identifying potential savings areas, develop a prioritized action plan based on:
Potential savings amount
Implementation difficulty
Time to realize savings
Impact on operations and customer experience
For each expense reduction opportunity, assign responsibility to a specific team member, set a clear target, and establish a timeline for implementation. For example, if you discover excessive office supply costs, you might assign your office manager to reduce these expenses within a set timeframe.
Document your findings in a simple tracking tool that allows you to monitor progress and calculate actual savings over time. This documentation creates accountability and helps quantify the value of your expense management efforts.
Step #2: Leverage Technology for Cost Tracking
Modern financial management software gives you real-time visibility into your operating expenses, allowing faster decision-making and more effective cost control.
Selecting the Right Expense Tracking Tools
Choose expense tracking software that offers:
Real-time expense reporting
Automated categorization of expenses
Custom dashboard views for different stakeholders
Integration with your accounting system
Mobile access for on-the-go expense management
Advanced analytics capabilities
The right system should match your business complexity and provide actionable insights without requiring excessive administrative time to maintain.
Automating Expense Workflows
Beyond tracking, technology can help you automate expense-related workflows to reduce overhead costs:
Implement digital approval processes for purchases
Set up automatic bill payments to capture early payment discounts
Create automated alerts for unusual spending patterns
Generate scheduled expense reports for regular review
Use optical character recognition (OCR) to digitize receipts and invoices
When you automate these routine tasks, you free up staff time for more strategic activities while improving expense control. For instance, automated approval workflows ensure proper authorization for all expenses while creating a digital audit trail.
3 Strategies for Optimizing Operating Expenses
Strategy #1: Negotiate Vendor Contracts
Vendor contracts represent significant opportunities for cost savings. Many businesses accept standard terms when they could negotiate more favorable arrangements.
Start by analyzing your spending across all vendors to identify your highest-value relationships. For these key suppliers, prepare for negotiations by:
Researching market rates and competitor offerings
Understanding your historical spending patterns with the vendor
Identifying areas where you could consolidate purchases for better volume discounts
Preparing specific requests for pricing, payment terms, or service levels
When negotiating, focus on creating win-win situations rather than simply demanding price reductions. For example, you might offer longer contract terms or faster payment in exchange for better pricing. Consider using a professional procurement specialist for high-value contracts if you lack internal expertise.
Track your savings from each negotiation to demonstrate the value of this strategy. Many businesses achieve significant savings through systematic vendor negotiations.
Strategy #2: Outsourcing Non-Core Activities
Outsourcing allows you to convert fixed costs to variable expenses while gaining access to specialized expertise. This strategy works particularly well for functions that:
Require specialized skills you don’t need full-time
Have predictable workloads that can be clearly defined
Are important but not part of your core competitive advantage
Have established service providers with proven track records
Common areas for outsourcing include IT support, payroll processing, customer service, accounting, and marketing services. Before outsourcing any function, conduct a thorough cost-benefit analysis comparing in-house expenses (including salaries, benefits, equipment, and management time) against outsourced costs.
When selecting service providers, look beyond price to consider:
Quality standards and service level agreements
Security practices, especially for data-sensitive functions
Cultural fit with your organization
Scalability to accommodate your growth
References from current clients
Successful outsourcing relationships require clear communication, well-defined expectations, and regular performance reviews. When done correctly, outsourcing can reduce costs while improving quality through specialized expertise.
Strategy #3: Invest in Energy-Efficient Solutions
Energy costs represent a significant expense for many businesses, especially those with physical facilities. Energy-efficient investments not only reduce ongoing operating expenses but often qualify for tax incentives and rebates.
Start with a professional energy audit to identify the most promising opportunities. Common energy-saving investments include:
LED lighting upgrades
HVAC system modernization
Smart building controls to optimize energy use
Improved insulation and weatherization
Solar panels or other renewable energy sources
For each potential investment, calculate the return on investment (ROI) considering:
Initial cost minus available rebates or tax incentives
Expected annual savings
Estimated useful life of the improvement
Maintenance requirements and costs
Prioritize projects with the fastest payback periods to build momentum. Many lighting upgrades, for instance, pay for themselves relatively quickly, while more extensive renovations might take longer to recoup their costs.
Beyond direct energy savings, these improvements often deliver secondary benefits like improved comfort for employees, reduced maintenance costs, and enhanced brand image through visible sustainability commitments.
What is the best way to control Operating Expenses?
The most effective approach to controlling operating expenses combines systematic tracking with process improvement and cultural change.
Building a Comprehensive Expense Control System
Develop a tracking and reporting system that provides:
Clear visibility into all expense categories
Regular variance analysis against budgets and forecasts
Trend analysis to identify potential issues early
Responsibility assignment for each expense category
Performance metrics linking expenses to business outcomes
This system should deliver the right information to the right people at the right time. Department managers need detailed expense data for their areas, while executives need summarized information highlighting exceptions and trends.
Schedule regular expense review meetings where responsible parties discuss variances, explain trends, and present cost optimization ideas. These meetings reinforce accountability and keep expense management a priority.
Process Optimization for Sustainable Cost Reduction
While budget cuts provide quick savings, process improvements deliver sustainable cost reduction without sacrificing quality or capacity. Look for opportunities to:
Eliminate redundant activities and approvals
Standardize processes across departments
Reduce error rates that cause rework
Implement lean principles to minimize waste, including improving stock management efficiency
Cross-train employees for greater flexibility
Document current processes before making changes, then measure the results after implementation. This documentation helps quantify savings and captures institutional knowledge for future improvement efforts.
To sustain these improvements, establish clear process ownership and regular review cycles. Each key process should have a designated owner responsible for monitoring performance and identifying new improvement opportunities.
Creating a Cost-Conscious Culture
Lasting expense control requires a supportive culture where all employees understand the importance of financial discipline. To build this culture:
Share financial information appropriately across the organization
Recognize and reward cost-saving ideas from employees
Include cost management in performance evaluations
Provide training on business financial fundamentals
Celebrate cost-saving successes
When employees understand how expenses affect business performance and see their role in managing costs, they become active partners in expense control. This cultural shift transforms expense management from a finance department function to an organization-wide responsibility.
The most successful organizations maintain this cost-consciousness even during prosperous times, creating financial resilience that helps them weather future challenges and invest in growth opportunities.
Frequently Asked Questions (FAQs)
How do operating expenses differ from the cost of goods sold (COGS) on a company’s financial statements?
Operating expenses are day-to-day costs for running the business (rent, salaries) not directly tied to producing goods, while COGS represents the direct costs attributable to creating the products sold.
Are capital expenses for long-term assets considered operating expenses?
No, capital expenses for long-term assets (like major equipment or property) are not operating expenses; they are capitalized on the balance sheet and typically depreciated over time.
According to a typical business operations faq, what is the foundational first step to improving how a business runs?
A foundational first step is to thoroughly assess current operations by mapping core business processes, identifying bottlenecks, and analyzing process waste to understand areas needing improvement.
What are the main categories of operating expenses that businesses typically track?
Main categories include administrative expenses (office supplies, management salaries), selling and marketing expenses (advertising, sales commissions), research and development, facility and occupancy costs (rent, utilities), and technology/equipment expenses.
Why is effective management of operating expenses vital for a business’s success?
Effective management is vital because it leads to improved budget control, enhanced financial performance and profitability, better cash flow management, stronger strategic decision support, and increased business resilience.
