What Is Food Cost Percentage?

Food cost percentage is the share of food sales spent on the ingredients that produced those sales. It is one of the clearest signals of how tightly a kitchen controls product cost relative to menu revenue.

Operators use it to compare periods, check a dish against the menu mix, and spot when supplier prices or portion habits are drifting. It does not replace a full P&L—but it answers a practical question fast: “What portion of each food dollar is going to ingredients?”

The simple definition

Total food cost is usually the cost of goods sold for food (ingredients used in the period, adjusted for inventory when you run a full COGS calculation). Food sales are the revenue from food items for the same period—not beverages unless you intentionally include them in a combined food-and-beverage cost percentage.

The formula

Food cost % = (Total food cost ÷ Food sales) × 100

Typical targets

Many restaurants aim for roughly 25–35% food cost, but the “right” number depends on concept, price point, and whether labor or food carries more of the margin story. Fine dining with high plate costs may run differently than a high-volume QSR with tight portion control.

• Under ~25%: often strong control or higher menu prices—verify quality and portion perception.
• About 25–35%: a common working range for many full-service concepts.
• Above ~35%: investigate waste, theft, portion creep, supplier changes, or underpriced dishes.

Why it matters operationally

A rising food cost percentage can mean ingredient inflation, inconsistent portioning, spoilage, comps that are not tracked, or menu prices that have not kept pace. A falling percentage can mean better purchasing—or cutting portions in ways guests notice.

Tracking the metric weekly (or by period close) keeps the conversation concrete: which dishes, which suppliers, which prep habits moved the number.

How to calculate it quickly

1. Choose a period (for example, last week or last month).
2. Total food cost for that period (or a dish’s ingredient cost for a plate-level check).
3. Total food sales for the same period (or the dish’s selling price).
4. Divide cost by sales and multiply by 100.
5. Compare the result to your target range and last period.

Plate cost vs period food cost

The same percentage formula works for a single dish (plate cost ÷ menu price) and for a full period (period food cost ÷ period food sales). Plate-level checks help engineer the menu; period-level checks show whether the kitchen as a whole is holding the line.

If you only know one kitchen metric by heart, make it food cost percentage—and know the formula behind it.
