Actual food cost is the value of food inventory consumed during a defined accounting period, calculated from opening inventory, purchases and closing inventory. It shows what the business actually used, rather than what it should have used according to recipe and sales calculations. It is commonly expressed as a dollar amount and as a percentage of food sales.
Opening food inventory + food purchases − closing food inventory = actual food cost.
For example, if a restaurant begins the month with $8,000 in food inventory, purchases $12,000 during the month and ends with $7,000, the basic actual food cost is:
$8,000 + $12,000 − $7,000 = $13,000.
To calculate the food cost percentage, divide actual food cost by the relevant food sales for the same period and multiply by 100:
Actual food cost % = (actual food cost ÷ food sales) × 100.
If food sales are $40,000 and actual food cost is $13,000, the food cost percentage is 32.5%. Use sales figures consistently, normally excluding sales tax and separating food from beverage or other revenue where appropriate.
Use consistent inventory categories and purchasing records. Depending on the accounting method, adjustments may be needed for transfers between locations, supplier credits, staff meals, complimentary items, waste, spoilage and non-food purchases. Document these consistently so period-to-period comparisons are meaningful.
Actual food cost is based on inventory movement and purchases. Theoretical food cost estimates what ingredients should have cost based on recipes, portion standards and items sold. Comparing the two can reveal over-portioning, waste, unrecorded sales, inventory errors, price changes or recipe-costing problems.
Chef’s tip: take physical inventory consistently and use the same cutoff dates for purchases and sales. A reliable actual food cost is only as accurate as the inventory counts and accounting records behind it.
