Food Cost Percentage: Formula, What's a Good %, and How to Lower It

A good food cost percentage for most restaurants is roughly 28–35% of food sales, though it depends on the concept: quick-service usually runs lower and fine dining higher. Calculate it as cost of goods sold ÷ food sales × 100, where COGS = opening inventory + purchases − closing inventory. Then work on the gap between what your recipes say food should cost and what it actually cost.

This guide covers the food cost formula with a worked example, realistic benchmarks by restaurant segment, the five leaks that quietly inflate food cost, and ten concrete control tactics you can start this week — whether you run a cafe, a coffee shop, a quick-service concept, or a full-service kitchen.

What Is Food Cost Percentage? The Formula

Food cost percentage is the share of your food revenue that goes to ingredients. It is the single most important number in restaurant cost management because it links purchasing, kitchen discipline, and menu pricing in one metric you can track weekly.

Worked example: your cafe starts the month with $4,000 of stock, purchases $9,500 during the month, and ends with $3,500 on the shelves. COGS = 4,000 + 9,500 − 3,500 = $10,000. If food sales for the month were $32,000, food cost percentage = 10,000 ÷ 32,000 × 100 = 31.25%. That means $0.31 of every dollar of food revenue is spent on ingredients before you pay for labor, rent, or anything else. The free food cost calculator does this math for a week, a month or a single dish.

Two versions of this number matter. Theoretical food cost is what your recipes say each dish should cost, multiplied by what you actually sold. Actual food cost is what the formula above shows really left your inventory. The difference — the variance — is your waste, over-portioning, theft, and untracked shrinkage. Many operators aim to keep variance under about 2 percentage points; anything wider means money is leaking somewhere you cannot see.

Food Cost Benchmarks by Segment

There is no single "correct" food cost — a sushi bar and a coffee shop live in different worlds. What matters is knowing the realistic range for your concept and holding your kitchen to it:

Where Food Costs Actually Leak

Before you can control food costs, you need to know where they escape. In most kitchens the gap between theoretical and actual cost comes from five sources, and none of them show up on an invoice:

Yield loss is the most underestimated of these. If a 5 lb beef tenderloin trims down to 3.8 lb of servable portions, your true cost per servable pound is 32% higher than the invoice price. Use a yield calculator to convert purchase prices into real cost-per-servable-portion — it changes how you price dishes and which cuts you buy.

Worked example: splitting the gap between theoretical and actual

Say your recipes put theoretical food cost at 30.0% of $40,000 in monthly food sales, but your inventory count shows an actual 33.5%. The 3.5-point gap is $1,400. Split it with the records you already keep, and each piece points to a different fix (example numbers):

10 Food Cost Control Strategies That Work

These tactics are ordered roughly by impact. You do not need all ten at once; start with the first four, which cover most kitchens’ biggest leaks.

1. Cost Every Recipe on a Standardized Recipe Card

You cannot control what you have not costed. Build a standardized recipe card for every menu item with exact weights for every ingredient, including garnish, sauce, bread and oil. Cost each line at its edible-portion price, not the invoice price: the food yield calculator converts one into the other. Multiply by current supplier prices to get the cost per portion, then re-cost monthly. A dish you costed in January is fiction by July.

2. Enforce Portion Control at the Line

Recipe cards are worthless if the line ignores them. Put scales at stations for proteins and expensive items, use numbered scoops and ladles for sides and sauces, pre-portion premium ingredients before service, and post plating photos at each station. Spot-check plates during service — consistency drifts within weeks without inspection.

3. Count Inventory Weekly

A monthly count tells you that you had a problem four weeks ago. A weekly count of your top 20–30 items by value (proteins, dairy, coffee, alcohol) lets you compute actual food cost weekly and catch variance while the trail is still warm. Full counts can stay monthly; high-value counts should be weekly.

4. Track Yield on Everything You Break Down

Run yield tests on proteins, fish, and produce you process in-house: weigh as purchased, weigh after trim, record the percentage. Feed real yields back into recipe costs so pricing reflects servable weight, not invoice weight. Re-test when you change supplier — the same cut from a different vendor can yield 5–10% differently.

5. Run FIFO and Tight Storage Discipline

First in, first out: date-label everything on receipt, store new stock behind old, and make rotation part of closing checks. Combine it with correct storage temperatures and covered containers and you eliminate most spoilage. For the full playbook, see our guide on how to reduce food waste in restaurants.

6. Log Waste Daily

Keep a waste sheet by the bin: item, quantity, reason, who logged it. Within two weeks patterns appear — burnt remakes point to training, spoilage points to over-ordering, plate waste points to portion sizes. What gets logged gets managed; unlogged waste just disappears into your food cost percentage.

7. Audit and Negotiate Supplier Prices

Review invoice prices on your top 20 purchased items monthly and compare at least two vendors per category quarterly. Ask for price locks on volatile items, volume tiers on high-use products, and early-payment discounts. Suppliers expect negotiation — silence is read as acceptance. Our guide on how to negotiate with restaurant suppliers covers scripts and tactics in detail.

8. Engineer the Menu Around Margin

Cross-reference each item's popularity with its contribution margin. Feature the stars (popular and profitable), re-price or re-cost the plowhorses (popular but thin margin), promote the puzzles (profitable but overlooked), and cut the dogs. Guide guests with menu placement, photos, and server recommendations toward the dishes that make you money.

9. Control Beverage Cost Separately

In cafes and bars, drinks deserve their own cost line. Coffee drinks usually carry a much lower cost percentage than food, and free-poured alcohol can drift well over spec without anyone noticing. Track pour cost per category with a pour cost calculator and standardize recipes for every drink, not just the food menu.

10. Re-Price Deliberately, Not Reactively

When ingredient costs rise, act on data: re-cost the recipe, then either adjust the price, adjust the portion, or re-engineer the dish. Small quarterly increases beat one painful annual jump. Knowing your numbers also tells you how much volume you need at current margins — run your figures through a break-even calculator to see exactly how many covers per day keep you profitable.
