How to Calculate Food Cost Percentage (The Complete Guide for Food Operators)
8 min read
Quick answer
Food cost percentage = (cost of ingredients used ÷ food sales) × 100. Calculate it per plate by adding the cost of every ingredient in one serving and dividing by the menu price, and calculate it per period using beginning inventory + purchases − ending inventory, divided by sales.
The two ways to measure food cost
Food cost percentage tells you how much of every sales dollar goes to ingredients. There are two versions, and you need both.
Plate cost (theoretical) is what one serving should cost if it is made exactly to recipe. Period cost (actual) is what you really spent over a week, event, or season, including waste, comps, and over-portioning.
Plate cost formula
List every ingredient in one serving, including the bun, sauce, oil, garnish, and packaging if you sell to-go. Convert each to the unit you use in the recipe, multiply by the price per unit, and add them up.
Then divide by the menu price. A sandwich that costs $3.10 to build and sells for $11 has a plate food cost of about 28%.
Period food cost formula
Actual food cost = beginning inventory + purchases − ending inventory. Divide that by food sales for the same period.
The gap between plate cost and actual cost is where money leaks: waste, theft, inaccurate portions, and price increases you have not passed on.
What to do when the number is too high
Start with the items you sell the most, because small fixes there move the total the most.
- Re-cost recipes with your latest receipt prices
- Standardize portions with scoops, scales, and pre-portioned packs
- Raise prices on high-volume items with thin margins
- Track leftovers and run-outs after every event
- Engineer the menu toward high-margin sellers
Keeping it current without spreadsheets
Ingredient prices change constantly, so a recipe costed once is out of date within weeks. MyFoodCostIQ reads your receipts, updates ingredient prices, and recalculates every plate automatically so you always see today's margin.
Frequently asked questions
What is a good food cost percentage?
It depends on your concept and menu. Many operators aim for roughly 25–35%, but the right target is the one that leaves profit after labor, fuel, fees, and other operating costs.
Should packaging be included in food cost?
If you sell mostly to-go, include it per plate. It is a real cost of every serving and it is easy to miss.
How often should I recalculate food cost?
Re-cost plates whenever supplier prices change and review actual food cost after every event or at least weekly.
