MENU COSTING
Food Cost Percentage Explained
Separate plate cost from period food cost, use comparable net sales, and investigate yield, waste, and mix before changing a menu price.

DIRECT ANSWER
The calculation in one paragraph
For a menu item, food cost percentage equals edible-portion ingredient cost divided by the item’s net selling price, multiplied by 100. For a period, actual food cost percentage equals cost of food used divided by food sales, multiplied by 100; cost used is beginning inventory plus purchases minus ending inventory, adjusted consistently for transfers and credits.

Recipe food cost percentage tests one item: total the edible-portion cost of every ingredient used in one sellable portion, then divide by the comparable net menu price. Period food cost percentage tests purchasing and operating results across the menu. Do not mix a plate cost numerator with total restaurant revenue.
Use net food sales under one documented policy. Taxes collected for government, tips, and non-food sales are normally kept outside this comparison. Discounts and comps need consistent treatment because a full menu price in the denominator can make actual recovery look better than it was.
Cost the portion you serve, not just the pack you buy
Convert purchase price to the recipe unit, then adjust for edible yield. If a $30 case produces 24 usable portions, the usable cost is $1.25 per portion before labor or overhead. If trim loss means only 80% of purchased weight is usable, edible-portion cost per pound equals as-purchased cost per pound divided by 0.80.
The USDA Food Buying Guide provides yield information specifically to estimate purchase quantities, control food cost, reduce waste, and produce adequate portions. Your supplier pack, specification, and observed kitchen yield should be retained because actual products and methods vary.
Food cost percentage is not profit margin
The percentage excludes labor, occupancy, utilities, merchant fees, delivery commissions, packaging, spoilage, and other operating costs unless you deliberately add them to a broader contribution model. A low food-cost item can still be unprofitable if it consumes scarce labor or generates high channel fees.
Compare theoretical food cost from recipes and sales mix with actual food used. The gap can point to portion drift, waste, unrecorded comps, receiving errors, price changes, or inventory-count problems. Investigate the driver before reacting with an across-the-board price increase.
WORKED EXAMPLE
Plate-cost example
- Edible-portion ingredients: $4.65
- Garnish and sauce: $0.55
- Net menu price: $18.00
($4.65 + $0.55) ÷ $18.00 × 10028.9% recipe food costThe remaining $12.80 is not profit. It must cover labor, occupancy, supplies, fees, waste, and other operating costs.
Two common food-cost views
| View | Numerator | Denominator |
|---|---|---|
| Menu item | Edible-portion recipe cost | Net selling price for that item |
| Accounting period | Beginning inventory + purchases − ending inventory | Net food sales for the same period |
| Theoretical period | Standard recipe cost × items sold | Net food sales for the same period |
A practical workflow
- Standardize the recipe, portion, and ingredient form.
- Convert each supplier price into the exact recipe unit and edible yield.
- Add portion ingredient costs and divide by net selling price.
- For period analysis, count inventory consistently and calculate food used.
- Compare theoretical and actual percentages, then investigate the largest variance.
EDGE CASES
Frequently asked questions
What is a good food cost percentage?
There is no universal target. It depends on concept, menu mix, labor model, rent, channel fees, waste, and required profit. Compare each item and period with a complete operating model and your own baseline.
Should labor be included in food cost?
Traditional food cost excludes labor. For a pricing decision, calculate a broader contribution or prime-cost view so labor and other variable costs are not ignored.
How often should ingredient costs be updated?
Update when supplier prices, pack sizes, specifications, or yields change materially, and review high-cost or volatile ingredients more frequently than stable minor ingredients.
