Food Cost Percentage: How to Price Your Menu So It Actually Makes Money
If you don't know your food cost percentage, you're guessing at your prices. Here's the simple formula, the numbers to aim for, and how to use them to price a menu that actually turns a profit.
Food Cost Percentage: How to Price Your Menu So It Actually Makes Money
Plenty of restaurants are busy and still broke. The tables are full, the kitchen’s slammed, the reviews are good — and at the end of the month there’s somehow nothing left. Nine times out of ten, the leak is the same one: the prices were set by feel, not by numbers, and the food cost quietly eats the profit.
The number that fixes this is your food cost percentage — how much of every dollar a dish brings in gets spent on the ingredients to make it. It’s the single most important figure in a kitchen’s economics, and a surprising number of owners have never actually calculated it. If that’s you, don’t feel bad. Let’s fix it, because once you can see this number, pricing stops being a guess.
What food cost percentage actually is
Food cost percentage is just the cost of the ingredients divided by the price you sell the dish for. If a burger costs you $3.50 in ingredients and you sell it for $12, your food cost on that burger is:
$3.50 ÷ $12 = 0.29, or 29%.
That means 29 cents of every burger dollar goes to the ingredients, and 71 cents is left to cover everything else — rent, staff, gas, equipment, and, eventually, your profit. Do that math for every dish and you can see, plate by plate, which items are quietly making you money and which are barely worth cooking.
Most restaurants aim for a food cost percentage somewhere between 28% and 35%. Below that and you might be underspending on quality or overcharging; well above it and you’re giving away margin you can’t afford. But “the industry says 30%” is a starting point, not gospel — a fine-dining tasting menu and a high-volume pizzeria live in very different places, and both can be healthy.
The whole-kitchen version of the number
The per-dish number tells you how each item performs. There’s a second version that tells you how the whole operation is doing, and you calculate it from what you actually bought and sold over a period — a week or a month:
Food cost % = Cost of Goods Sold ÷ Total Food Sales × 100
Cost of Goods Sold (COGS) is what the food you actually used cost you. You work it out like this:
Starting inventory + purchases − ending inventory = COGS
In plain terms: take what was in your fridges and store room at the start, add everything you bought during the period, then subtract what’s still on the shelf at the end. That’s what you consumed. Divide it by your food sales for the same stretch, and you’ve got your real, whole-kitchen food cost percentage.
Here’s why this one matters even if your per-dish math looks fine: it catches everything the recipe card doesn’t. Waste, over-portioning, spoilage, theft, the cook who’s heavy-handed with the expensive cheese — all of it shows up as a gap between what your dishes should cost and what your kitchen actually spent. If your menu says 30% but your monthly number is 38%, you’ve got eight points leaking out somewhere on the floor, and now you know to go find it.

Pricing a dish from the cost up
Once you know a dish’s food cost, pricing it stops being a vibe. Flip the formula around. If you want a dish to hit a 30% food cost and it costs you $4.50 to make:
$4.50 ÷ 0.30 = $15.
So $15 is your floor for that plate if 30% is your target. That’s the number that keeps the lights on. From there you adjust for the real world — what the place down the street charges, what your guests will happily pay, whether it’s a signature dish people will stretch for or a staple they expect to be cheap. The formula gives you the honest starting line; your judgment sets the final price. What you never do again is pull a number out of the air and hope.
This is also where pricing psychology and food cost meet. Costing tells you the floor; smart menu pricing and menu design decide how far above it you can comfortably go. The two work together — one keeps you safe, the other grows the margin.
Turning the number into more profit
Knowing your food cost is step one. Using it is where the money is.
- Reprice the losers. Some dish on your menu almost certainly has a food cost of 45% because ingredient prices crept up and the price never moved. Find it and fix it — a small bump, or a small tweak to portion or plating, often rescues the margin without a single complaint.
- Push the winners. The flip side: your lowest-food-cost, highest-margin dishes are the ones you want to sell the most of. Once you know which they are, feature them — top of the section, a photo, a staff recommendation.
- Watch it over time, not once. Ingredient prices move constantly. A number you calculated last year is fiction now. Recheck your costs when supplier prices jump, and treat food cost as a dial you monitor, not a thing you did once.
- Update prices without the pain. A big reason menus fall out of sync with costs is that changing them is a hassle — reprinting, reformatting, redesigning. When your menu is digital, you can adjust a price the moment a supplier cost changes and it’s live instantly, so your prices never fall a year behind your costs again.
Keep your prices and your costs in sync
With Lekro’s digital menu, you can reprice any dish in seconds the moment your costs change — so your menu never drifts out of profit. Start free.
You don’t need to be an accountant to run a profitable kitchen. You need one number, checked regularly, applied honestly. Calculate your food cost percentage this week — per dish and for the whole kitchen — and you’ll almost certainly find a few points of profit that have been walking out the back door. Prices set by math beat prices set by hope, every single month.
