Restaurant Food Cost Calculator and Menu Pricing
This restaurant food cost calculator compares a dish's ingredient cost with its selling price: current food cost percentage, the target selling price for your goal, gross margin and tax-inclusive prices. An alert flags any dish selling below its ingredient cost.
Calculated results
Gross margin on ingredient cost does not account for wages, rent, commissions, untracked losses or other overhead: it is not net profit.
The tax rate is configurable by country and category: the calculator does not determine the applicable legal rate (e.g. VAT).
Method and limits
How to use this calculator
Enter the dish's ingredient cost — plus any additional direct cost — and its current selling price excluding tax. Set your target food cost percentage, for example 30% for a classic benchmark, and the applicable tax rate. The current ratio, target selling price, gross margin and tax-inclusive prices appear immediately, with an alert if the dish sells below its ingredient cost.
Food cost percentage is FC = cost / price × 100; the target selling price is P_target = cost / (FC_target / 100). Gross margin is M = price − cost, in dollars and as a percentage of the selling price, and tax-inclusive prices follow P_taxed = P × (1 + t). This margin does not account for wages, rent, commissions or untracked losses.
Current food cost and target price
The calculation keeps ingredient cost separate from the additional direct cost: the first defines the food cost percentage, both together define gross margin. The target price follows from the goal: at a 25% target food cost, every dollar of ingredients calls for $4 of sales before tax. A zero selling price, a zero target and a target above 100% are blocked with explicit messages; selling below ingredient cost triggers a warning.
Gross margin, tax and limits
Gross margin on ingredient cost is never presented as net profit: wages, rent, energy and commissions remain to be covered — adding labor turns the figure into prime cost, which is benchmarked differently. The tax rate, set per country and product category, converts prices to tax-inclusive for display without ever mixing the two bases in the ratio: collected sales tax or VAT is not operating revenue. The calculator does not determine the applicable legal rate, and this is not tax advice.
Worked example
A dish with $6.00 of ingredients plus $0.50 of takeout packaging, sold at $20.00 before tax: a 32.50% food cost and a $13.50 gross margin (67.50% of the selling price). For a 25% target, the target selling price rises to $26.00 before tax — $28.08 with an 8% sales tax — while the current price becomes $21.60 with tax. Reproduce these values in the tool: you must get exactly the same results.
Assumptions and limits
The ratio is computed on the selling price excluding tax: including collected sales tax or VAT would mechanically understate the food cost percentage. Gross margin on ingredient cost is a purchasing-control indicator, not an income statement — it deducts neither wages, nor rent, nor commissions. The tax rate is yours to enter: the calculator does not determine the applicable legal rate, and this is neither accounting nor tax counsel. Values are per-dish estimates and ignore purchase price fluctuations.
