What Is Food Cost? How Restaurants Calculate It
Food cost is the ratio of ingredient cost to selling price per portion. This guide covers recipes, waste and inventory.
What is food cost?
Food cost (food cost ratio) is the share of restaurant revenue that goes to raw materials and direct food costs. The most common formula: opening stock + purchases in the period − closing stock = cost used; cost used ÷ net food sales = food cost percentage.
The ratio ties directly to kitchen discipline, portion standards, waste, and menu pricing. Ritapos stock and sales data feed the food cost calculator; the profitability principles in what to watch when building a restaurant menu support your food cost target when you design the menu.
Calculating portion cost
Net portion cost for each recipe: ingredient list × unit price, plus a waste allowance. For example, 200 g beef with 10% waste is calculated from 220 g consumption. If sauce, garnish, and bread costs are omitted, true food cost rises.
Portion scales and kitchen measuring cups align theoretical recipes with what leaves the pass. Recipe definitions in Ritapos automate stock deductions; manual adjustments show up in waste analysis.
- Write the recipe with weights.
- Keep supplier invoice unit prices up to date.
- Add a waste percentage for each ingredient.
- Divide portion cost by selling price; compare to your target food cost.
- Update menu price when needed.
Target rate and sector
Target food cost differs for fine dining, fast casual, and cafe models; one number does not fit every venue. Use your own past-period average as a baseline; when variance spikes, analyze causes (price increases, portion drift, theft, count errors).
In beverage-heavy venues food cost can look low; track categories separately for a blended view.
| Item | Effect on food cost |
|---|---|
| Portion standard | High variance raises the ratio |
| Waste and spoilage | Shows up in stock variance |
| Menu mix | Low-margin bestsellers skew the ratio |
| Discount campaigns | Lower net sales raise the ratio |
Stock counts and period close
Weekly or monthly stock counts make food cost calculations reliable. Keep service stock separate on count night; standardize open containers in the kitchen.
Ritapos count mode reports the gap between physical and system stock; when variance is high, investigate portion or recipe errors.
Menu engineering
Make high-margin signature items visible on the menu; raise prices or shrink portions on low-margin dishes. Food cost is a function of sales mix, not cost alone.
Combo menus raise average ticket but hurt food cost if the bundle is not costed like a recipe; cost combo contents as you would a recipe card.
Theoretical and actual food cost
Theoretical food cost comes from recipes; actual food cost comes from stock counts and sales data. The gap shows portion drift, waste, or count errors.
Review the weekly theoretical vs actual variance report with the chef; a persistent positive gap calls for portion training.
Ritapos recipe module deducts theoretical usage automatically; count variance defines actual cost.
Purchasing and suppliers
When you change supplier, weigh unit price and quality together; cheaper meat can mean higher waste.
Updating menu prices weekly when seasonal vegetable prices move helps avoid food cost spikes.
Central purchasing contracts align branch food cost targets.

Frequently Asked Questions
What food cost percentage should I target?
It varies by business type; track your own trend. Industry averages can be a reference, but the target must fit your P&L structure.
Are food cost and gross margin the same?
Food cost is the food cost ratio; gross margin looks at what remains after all variable costs. Payroll and rent are not in the food cost formula.
How often should I use the calculator?
When prices rise, the menu changes or suppliers change, rerun simulations with the food cost calculator; at monthly close at minimum, calculate the actual ratio.
Does delivery increase food cost?
Packaging, platform commission and promotions cut net margin; use a separate cost and price strategy for the delivery menu. Delaying menu price updates when supplier unit costs rise temporarily inflates food cost; define a temporary tolerance band. If comps and staff meals are not deducted from stock, food cost looks too low; keep the policy clear.
