A net profit margin of 5% to 10% is typical for a small business, and anything around 20% counts as strong. But the single most important thing to know about profit margin for small businesses is that the benchmark is almost entirely a function of your industry. A 4% net margin is comfortable in a restaurant and a crisis in a retail shop, and comparing yourself to the wrong sector is worse than not comparing at all.
This post covers the two margins you need, what the figures look like trade by trade, and the five levers that move the number once you know where you stand.
The Bottom Line
- Gross margin = (revenue − cost of goods sold) ÷ revenue. Net margin = net profit ÷ revenue. Track both; the gap between them is your overhead.
- DoorDash’s industry data puts full-service restaurants near 2.8% net, quick service around 4%, retail at 3–8% and flower shops around 20%.
- Five levers move margin: price, product mix, cost of goods, fulfilment cost and overhead. Price is the fastest and the most feared.
- A thin margin is only dangerous relative to volatility. 3% is survivable with predictable costs and fatal without.
- Discounting to defend revenue is the most common way small businesses destroy their own margin.

Gross margin and net margin, and why you need both
Two calculations, measuring different things.
Gross profit margin = (revenue − cost of goods sold) ÷ revenue × 100
This is what remains after the direct cost of whatever you sold: ingredients, stock, materials, the labour that goes directly into the product. It tells you whether the thing you sell is priced properly.
Net profit margin = net profit ÷ revenue × 100
This is what survives everything: rent, wages, insurance, vehicles, software, interest and tax. It tells you whether the business works.
Watch them together, because the gap between them is your overhead burden and it tells you where a problem lives. Healthy gross margin with poor net margin is an overhead problem, and no amount of price increase fixes it sustainably. Poor gross margin is a pricing or purchasing problem, and cutting overhead will not touch it.
A worked example. Revenue of £300,000, cost of goods £180,000, overheads £105,000. Gross margin is 40%, net margin is 5%. The 35-point gap is the overhead, and in this business the realistic route to a better net margin runs through that £105,000, not through the pricing.
Average profit margin by industry
The ranges below are drawn from published industry figures and should be read as orientation rather than precision. Margins vary by region, scale and business model within every one of these categories.
| Sector | Typical net margin |
|---|---|
| Full-service restaurants | ~2.8% |
| Quick-service restaurants | ~4% |
| Retail | 3–8% |
| Landscaping | ~8% |
| Salons | 10–20% |
| Liquor stores | 15–20% |
| Flower shops | ~20% |
| Professional services | 15–25% |
Food businesses sit at the bottom of this table for structural reasons: perishable stock, labour-intensive preparation and customers who are price-sensitive. If you are in that category, average restaurant profit margins and how to improve them goes into the specific cost lines that move the number. Service businesses sit at the top because they carry little inventory and sell time rather than goods.
The useful takeaway is not where you rank but what the number implies about your margin for error. A 3% net margin means a 3% increase in costs wipes out your profit entirely. A 20% margin absorbs a bad quarter. Thin margins are workable, but they demand much tighter control of the things that move, which in practice means watching the cash flow metrics weekly rather than reviewing the accounts quarterly and hoping.
The five levers that move profit margin
Margin only improves through five routes. Most owners reach for the fourth and fifth and avoid the first, which is backwards.
Raise prices
The fastest and most effective lever, and the one that generates the most anxiety.
The arithmetic is worth sitting with. On a 5% net margin, a 5% price increase roughly doubles your profit, provided volume holds. Losing even 10% of your volume still leaves you ahead. Compare that to cost-cutting, where you would need to find savings equal to 5% of total revenue to achieve the same result, and those savings usually cost something in quality.
The reason owners resist is fear of losing customers, and that fear is usually overstated for a small, established business with real relationships. Customers who value reliability and service do not leave over 4%. The ones who leave over 4% were price shoppers who would have left anyway, and they are typically your least profitable accounts.
Practical approach: raise prices on new customers first, give existing customers notice, and raise selectively rather than across the board. Which items can take an increase is a question about per-product economics rather than about the business average.
Change the product mix
Not every line you sell makes the same money. Shifting volume toward the profitable ones raises your blended margin without changing a single price.
This requires knowing margin per product rather than overall, which many small businesses do not. The analysis frequently turns up a surprise: a popular item sold at or below cost, propped up by the belief that it brings people in, or a slow-moving line carrying the best margin in the catalogue and getting no promotion at all.
Reduce cost of goods
Supplier negotiation, consolidating orders for better pricing, substituting inputs, and reducing waste.
Waste is the one most often left on the table in food businesses, where spoilage can quietly consume several points of margin. It rarely shows up as a line item labelled “waste”, which is precisely why it persists.
Supplier pricing is worth revisiting annually as a matter of routine. Prices agreed three years ago at a smaller volume are usually improvable simply by asking, and the conversation costs nothing.
Cut fulfilment and delivery cost
For anyone shipping goods, this is frequently the largest cost sitting outside the cost of goods, and the least examined.
The number to know is cost per delivery, calculated honestly: vehicle, fuel, driver time, insurance, maintenance and the admin around it. Set against the average order on that route, the result is often uncomfortable, especially for small orders travelling a long way.
Two fixes, both structural. Consolidate drops so each journey carries more revenue, which is a routing question. And raise the revenue per drop, which is where average order value does more for margin than it does for growth: the delivery cost is largely fixed per stop, so a larger order at the same stop is almost pure margin. A minimum order value for delivery is the blunt version of the same idea and often the right call.
Trim overhead
The lever everyone starts with, and usually the smallest.
Subscriptions nobody uses, insurance never re-quoted, premises larger than needed, finance arranged when your credit profile was weaker. Worth a review annually, and worth being honest that it is a one-off gain rather than a structural improvement. You cannot cut your way to a good margin twice.
Reading your margin against volatility rather than a benchmark
The most useful question about your margin is not “is it above average” but “how much can go wrong before it disappears”.
Work out what a 5% rise in your main input cost does to net profit. Then what losing your largest customer does. Then a month of bad weather, or a vehicle off the road for three weeks.
A business with a 4% margin and highly predictable costs can be perfectly sound. A business with a 12% margin and one customer representing 40% of revenue is more fragile despite looking healthier. Margin and risk have to be read together, which is also why margin alone is a poor guide to whether growth is working: revenue rising while margin falls is a pattern worth catching early, and the revenue growth metrics set out how to watch the two lines side by side.
Before any investment intended to improve margin, run the numbers as a return-on-investment calculation rather than a hope. Equipment that reduces waste or labour has a payback period you can estimate, and estimating it beforehand is what separates a margin improvement from an expensive guess.
What not to do to your margin
Do not discount to hold revenue. On a 30% gross margin, a 10% discount costs a third of your gross profit on that sale. Volume has to rise by roughly 50% just to break even on the trade. Discounting is occasionally the right tactic and almost never the right strategy.
Do not cut the things customers notice. Reducing portion sizes, downgrading packaging or slowing delivery buys a point or two of margin and costs you advocacy, which shows up later in orders. If service quality starts slipping under cost pressure, net promoter score will register it before revenue does.
Do not rely on a blended average. A 15% overall margin can comfortably contain lines losing money. The average hides exactly the information you need to act.

Frequently asked questions
What is a good profit margin for a small business?
Net margin of 5% to 10% is typical and around 20% is strong, but industry is the dominant factor. Restaurants operate on single digits by nature; professional services routinely clear 20%. Compare within your own trade.
What is the difference between gross and net profit margin?
Gross margin deducts only the direct cost of what you sold. Net margin deducts everything, including rent, wages, insurance and tax. The difference between them is your overhead.
How do you calculate profit margin?
Divide profit by revenue and multiply by 100. Use gross profit for gross margin and net profit for net margin, and make sure both come from the same period.
Is a 10% profit margin good?
For most small businesses, yes, and it is likely sustainable. Going much below it leaves little tolerance for cost increases or a quiet month, which is the real risk of a thin margin rather than the headline figure itself.
What is the fastest way to improve profit margin?
A price increase, by a wide distance. On thin margins a few percent on price produces more profit than any cost-cutting exercise you could realistically complete, and it takes effect immediately.
Where to start
Calculate both margins for the last full quarter. If the gross margin looks weak for your trade, the work is in pricing and purchasing. If the gross looks fine and the net does not, the work is in overhead and fulfilment.
Then break gross margin down by product line. That analysis takes an afternoon and more often than not identifies a line you are selling at a loss, which is the single most valuable thing a margin review can turn up.
