Home › Food Business Calculators › Food Cost Percentage Calculator
Calculate the percentage of a portion’s selling price represented by its ingredient or food cost. The tool also reports gross profit per portion and the corresponding gross-margin percentage. Use a consistent currency and cost basis for both inputs.

Equation and interpretation
Food cost percentage = cost per portion ÷ selling price per portion × 100%. Gross profit per portion = selling price − cost. Gross margin percentage = gross profit ÷ selling price × 100%. The calculator requires a non-negative cost and a selling price greater than zero.
Food cost percentage and gross margin are complementary only under the entered two-value model: food cost percentage + gross margin percentage = 100%. If the cost input includes ingredients only, the gross margin shown is before labor, rent, utilities, taxes, commissions and other expenses.
Verified numerical example
If one portion costs 4.50 and sells for 12.00, food cost percentage = 4.50 ÷ 12 × 100 = 37.5%. Gross profit per portion = 12.00 − 4.50 = 7.50. Gross margin = 7.50 ÷ 12 × 100 = 62.5%. The two percentages add to 100% because the model compares only the entered food cost with the selling price.
How to use the calculator
- Enter the ingredient or food cost for one portion.
- Enter the selling price for that same portion, in the same currency.
- Calculate and review the food-cost percentage and gross profit.
- Check whether other variable or operating costs need a separate calculation before setting a final menu price.
Cost basis and limitations
The tool does not determine whether a food-cost percentage is good or bad for every business. Targets vary by concept, menu mix, labor model, location and operating expenses. A low ingredient-cost percentage does not guarantee profitability if labor, rent, waste or sales volume are unfavorable.
Use actual recipe quantities and current purchase prices to estimate portion cost. If you compare the result over time, keep the recipe, serving size, purchase-price basis and treatment of waste consistent. Tax-inclusive selling prices can distort comparisons if one input includes tax and another does not.
Frequently asked questions
Is food cost percentage the same as gross margin?
No. In this simple model they add to 100%, but they describe different shares: food cost is cost divided by selling price, while gross margin is profit divided by selling price.
Should labor be included in food cost?
This calculator uses the cost you enter. Many operators track food cost and labor cost separately, then combine them for broader prime-cost analysis.
What if the cost is higher than the selling price?
The calculator returns a food-cost percentage above 100% and a negative gross profit, indicating the portion sells below its entered cost.
