Gross Profit vs Net Profit

Introduction

Gross profit is what remains from revenue after subtracting food cost. It is a clear lens on food margin before labor and other operating expenses. Net profit is the final bottom-line after all expenses, including labor, rent, utilities, marketing, and more.

Use the table of contents to jump to formulas, worked examples, and the common mistakes that confuse food margin with full profitability.

Step-by-step: understand gross profit math

1. Start with revenue (menu sales for food, or your selling price multiplied by covers).
2. Enter food cost for the same item or period (plate cost or total food cost).
3. Compute gross profit = revenue − food cost.
4. Compute gross profit % = (gross profit ÷ revenue) × 100.
5. Compute food cost % = (food cost ÷ revenue) × 100. For a single item/period, these sum to 100%.

Gross profit formula

Gross Profit = Revenue − Food Cost
Gross Profit % = (Gross Profit ÷ Revenue) × 100
Food Cost % = (Food Cost ÷ Revenue) × 100

Gross profit vs net profit (what changes?)

Common mistakes

• Using net profit thinking when you only have gross profit math.
• Mixing food cost definitions (e.g., including labor in “food cost”).
• Comparing a single dish gross profit to period net profit without controlling for sales mix.
• Assuming gross profit % predicts full profitability without considering labor and overhead.

Best practices

• Use this calculator to isolate food margin and then pair it with labor and prime cost work for full economics.
• Recompute with the same food revenue scope you use for food cost (food sales only, not beverages unless intended).
• Validate after pricing: once sales are live, measure actual gross profit % and food cost %.
• Use dish-level gross profit comparisons to guide menu engineering decisions.
