Food cost percentage is the proportion of food sales represented by the cost of the food used to produce those sales, expressed as a percentage. Restaurants use it to monitor ingredient spending, evaluate menu pricing and compare actual performance with theoretical recipe costs.
Food cost % = Food cost ÷ Food sales × 100
For an actual period calculation, food cost should be based on inventory usage and purchases according to the business’s accounting method. For an individual menu item, use the standardized recipe cost and the selling price, excluding applicable taxes and using a consistent sales basis.
If a dish has an ingredient cost of $3.60 and sells for $14.00, its recipe food cost percentage is:
$3.60 ÷ $14.00 × 100 = 25.7%.
Theoretical food cost estimates the cost expected from standardized recipes and the sales mix. Actual food cost measures the food consumed during a period using inventory and purchasing records. The difference between them is a useful variance to investigate.
Supplier prices, recipe specifications, yield, portion size, menu mix, waste, spoilage, staff meals, complimentary items, inventory accuracy and sales recording can all influence food cost percentage. A lower percentage is not automatically better if it comes at the expense of quality, portion satisfaction or sales.
Chef’s tip: Compare food cost percentage with contribution margin, sales volume and guest satisfaction. A single target cannot suit every restaurant, menu style or price point.
Key distinction: Food cost percentage is a ratio, not a dollar amount. It should be calculated using a clearly defined food-cost and sales basis.
