Food cost percentage is what you spent on food divided by what you sold, over the same period. At 30%, every $10 entrée carries $3 of ingredients and leaves $7 for labor, rent, utilities, and whatever is left over for you. The arithmetic is trivial. The useful part is what the number tells you once you have it, which is where most operators stop short.
Treat a food cost percentage as a symptom rather than a grade. Two points higher than last quarter could mean beef went up, or it could mean a new cook is heavy-handed with the protein, or that your walk-in is running warm, or that you never re-priced a menu you costed in 2023. Those have completely different fixes, and picking the wrong one is why so many food cost initiatives produce a cheaper-tasting menu instead of a better margin.
This covers how to calculate it so the number holds up, what range your format should sit in, and how to read a bad one back to its cause.
The Bottom Line
- Food cost % = (beginning inventory + purchases − ending inventory) ÷ food sales for the same period.
- Most full-service restaurants land between 28% and 35%; the industry average sits around 32.4%.
- Judge it alongside labor as prime cost. Under 60–65% combined is the viability line.
- A high number has four usual causes: pricing, portioning, waste, and purchasing. Diagnose before you cut.
- Run it weekly, not monthly. A monthly number tells you what went wrong after you can no longer fix it.

How to calculate food cost percentage correctly
The formula every operator knows:
Food cost % = (Beginning inventory + Purchases − Ending inventory) ÷ Food sales × 100
A worked example for one week. You start Monday with $12,000 of inventory on the shelves. You buy $9,500 during the week. Sunday night you count $11,000 still sitting there. You sold $31,000 of food.
Cost of goods used = 12,000 + 9,500 − 11,000 = $10,500
Food cost percentage = 10,500 ÷ 31,000 = 33.9%
Simple enough. The errors are all in the inputs, and they are common enough to be worth listing:
- Counting inventory inconsistently. Same day, same time, same person, same unit of measure. A count taken Friday one week and Monday the next is not comparable to anything.
- Mixing beverage into food. Alcohol runs at a radically different cost ratio and will flatter or wreck the number depending on your mix. Track them separately.
- Using purchases instead of usage. Purchases alone ignore what is sitting in the walk-in. In a week with a big delivery you will look terrible; the week after, heroic. Neither is real.
- Mismatched periods. The inventory count and the sales figure have to cover the same days. Obvious, routinely violated.
- Forgetting comps, staff meals, and waste. The food left the shelf. If you do not account for it, it shows up as an unexplained variance you will spend an afternoon chasing.
There are two other numbers worth distinguishing. Ideal food cost is what your sales mix should have cost based on costed recipes, the theoretical number. Actual food cost is the one above. The gap between them is the interesting part, and it is where portioning, waste, and theft live. If your ideal is 29% and your actual is 34%, you do not have a pricing problem. You have five points of execution leaking somewhere.
What a good food cost percentage looks like by restaurant format
There is no universal target. A steakhouse and a pizzeria running the same percentage are in very different health, because what they can charge and what their labor costs differ enormously.
| Format | Typical food cost % | Why it sits there |
|---|---|---|
| Pizzeria | 20–28% | Cheap base ingredients, high markup potential |
| Quick service | 25–30% | Tight portion control, simplified menu, low labor |
| Fast casual | 28–32% | Better ingredients traded against counter service |
| Casual dining / full service | 28–35% | The broad middle; industry average around 32% |
| Steakhouse | 35–45% | Expensive protein, offset by beverage and higher checks |
| Fine dining | 30–40% | Premium ingredients, offset by high check averages |
| Bakery / café | 25–35% | Low ingredient cost, high labor and waste exposure |
| Catering | 25–35% | Predictable volume and minimal waste, when it is quoted properly |
The industry average for full-service restaurants is roughly 32.4%, per the National Restaurant Association’s 2026 State of the Industry data. Treat that as a reference point rather than a goal. Being three points above it with a steak program is normal, and being three points below it with a sandwich shop may mean you are under-portioning.
Never read the number alone. Food cost only makes sense next to labor, as prime cost:
Prime cost = food cost + labor cost, as a percentage of sales
The working benchmark is 60%, with 65% as the ceiling for a viable restaurant. This matters because the two trade off constantly. Buying pre-portioned protein raises food cost and lowers labor. Butchering in house does the reverse. An operator who drives food cost down by moving every task into the kitchen has not saved anything — they have moved the cost to a different line. Prime cost is the number that cannot be gamed this way, and it is the one to anchor on. In an industry where the National Restaurant Association’s 2025 operating survey found median pre-tax income of just 2.8% of sales for full-service restaurants, a few points of prime cost is the entire business.
Why your food cost percentage is high: four diagnoses
A high number is never just “food costs too much.” Work through these in order, because they go from cheapest to fix to most expensive.
Menu pricing that hasn’t kept up with invoices
The most common cause and the easiest to miss, because nothing about it feels like a problem. Ingredient prices moved; your menu didn’t. Every item you costed eighteen months ago is now running several points high, and nothing on the floor tells you so.
Check by re-costing your top ten sellers at today’s invoice prices, not last year’s. If the gap is broad across the whole menu, this is your answer, and the fix is a pricing pass rather than an operational one. Small adjustments across many items beat a big jump on a few; customers notice the $2 increase on their regular order far more than $0.50 spread across the menu.
Portion sizes that drift upward
Portion drift is invisible by design. Nobody decides to serve more; it just creeps, especially after a staffing change. Six ounces becomes seven becomes “about that much.” On a dish selling 200 covers a week, an extra ounce of protein is real money by month end.
The tell is a widening gap between ideal and actual food cost with no change in purchasing. The fix is scales, spec photos, and a manager who checks plates during service rather than at the pass once a month. This is also the problem that spreads fastest across locations, which is why consistent plate specs are central to running two or more restaurant locations — when one store runs several points higher than another on the same menu, portioning is the first place to look.
Kitchen waste you aren’t measuring
Three kinds, and they need separate tracking: spoilage (over-ordering, bad rotation, a walk-in running warm), prep waste (yield loss from trim, peel, and bone, which is predictable and routinely underestimated), and service waste (remakes, comps, dropped plates, over-production of specials).
Keep a waste log for two weeks. Not forever, just long enough to find out which of the three is costing you. Most operators are surprised by which one it is, and the guessed answer is usually wrong.
Purchasing terms you haven’t challenged
Line items nobody has re-bid in years. Deliveries received without checking weights against the invoice. Three suppliers where one would give you volume pricing. Specialty products bought at specialty prices out of habit rather than need.
Receiving is the overlooked half of this. A short delivery you sign for is a 100% cost item. Weighing in key proteins and spot-checking case counts takes minutes and catches more than most operators expect. Consolidating volume also gets cheaper the bigger you are, which is one of the few hard financial advantages of expanding to a second restaurant location: two kitchens buying together can ask for pricing neither could get alone.
How often to measure food cost percentage
Monthly is the default and it is too slow. A monthly number tells you in the second week of November that something went wrong in October, by which point the cause has been running for six weeks and the money is gone.
Weekly is the right cadence for the overall number. It is frequent enough to connect a result to a specific thing that happened, whether a new cook, a supplier change or a menu special, and infrequent enough that counting inventory does not consume the business.
Daily counts pay off on your highest-cost items only. Proteins, seafood, anything expensive and portion-sensitive. A short daily count of six items catches the expensive drift without a full inventory.
Per-plate, continuously, if your POS and inventory system talk to each other. Theoretical usage against actual usage, item by item, is the fastest diagnosis available. It tells you not just that you are five points high but which dish is responsible.
The discipline matters more than the tooling. A weekly count on a clipboard, done consistently by the same person in the same order, beats a sophisticated system nobody updates.
Lowering food cost without making the food worse
The failure mode of every food cost project is trading down on quality, improving the percentage for one month, and then watching covers fall as regulars stop coming. The savings disappear into a softer top line and you have made the restaurant worse.
The levers that don’t cost you quality:
- Engineer the menu. Plot each item by popularity and contribution margin. Promote the high-margin items people already like, re-work the popular low-margin ones, and cut the items that are neither. This usually moves the number more than any purchasing change.
- Re-bid, don’t trade down. Same product, better price. Most operators have not tested the market on their top 20 line items in years.
- Use the whole product. Trim into stock, bones into demi, day-old bread into something that sells. Yield improvement is free margin.
- Cross-utilize ingredients. An ingredient that appears in one dish only is a spoilage risk. Ingredients that appear in three dishes turn over faster and waste less.
- Tighten receiving. Weigh it, count it, check it against the invoice. Free.
- Raise prices where the market allows. Not every item, not all at once. But under-pricing is a common cause of a high food cost percentage, and the fix for it is not cheaper beef.
Pick one lever and finish it before starting the next. A kitchen running four cost initiatives at once produces no measurable result from any of them, because you lose the ability to tell which change caused what.
Frequently asked questions
What is a good food cost percentage for a restaurant? Most restaurants target 28–35%, with the full-service average around 32%. The right number depends on your format: a pizzeria should be well under 30%, a steakhouse can run above 40% and still be healthy. Judge it as part of prime cost rather than alone.
What’s the difference between food cost and food cost percentage? Food cost is a dollar amount: what the ingredients cost. Food cost percentage expresses that as a share of food sales, which is what makes it comparable across weeks, locations, and restaurants of different sizes.
How do I calculate food cost percentage for a single menu item? Divide the item’s total ingredient cost by its menu price. A burger with $3.60 of ingredients selling at $14 runs 25.7%. Include everything that goes on the plate: garnish, sauce, bun, and the portion of oil, salt, and seasoning most costings ignore.
Is a lower food cost percentage always better? No. Pushed too low it usually means under-portioning, cheap ingredients, or over-pricing, and all three cost you customers eventually. A restaurant at 24% with falling covers is in worse shape than one at 33% with a line out the door.
Should beverages be included in food cost percentage? No. Track beverage cost separately. Alcohol typically runs 18–24% and will distort your food number in either direction depending on your sales mix.
