Quick guide
How to use this calculator
- Gather Food cost, Beverage cost, and Total labor cost for the same business scenario before calculating.
- Match the trading period, location scope, available capacity, and revenue definition; gross sales, net sales, receipts, and recognized revenue may differ.
- Apply the displayed restaurant prime cost result to the stated decision only after checking every entered assumption.
Calculation method
Calculation method
Prime cost = food cost + beverage cost + total labor cost.
The calculation uses these named inputs: Food cost, Beverage cost, and Total labor cost. No market rate, benchmark, tax rule, or accounting classification is inserted automatically.
Fixed-decimal arithmetic remains exact through display unless a result is explicitly labelled approximate, such as a square-root inventory quantity.

Where the Restaurant Prime Cost Calculator helps
Calculate restaurant prime cost from food, beverage, and labor costs.
Use the result to relate entered traffic, capacity, sales, stock, labor, seats, rooms, or service time within one clearly bounded operation.
- Review a store or service period
- Compare capacity and demand scenarios
- Identify which entered operating driver explains a variance
Interpretation check
How to audit the result
Recalculate the scenario when any of these inputs changes: Food cost, Beverage cost, and Total labor cost.
Keep this formula beside the result: Prime cost = food cost + beverage cost + total labor cost. Then compare the output with the source records and the calculator-specific assumption below.
- Confirm that all amounts use one currency and reporting period.
- Check that rates, counts, and quantities describe the same population or transaction set.
- Save the entered assumptions with the decision; the result alone is not reproducible evidence.
Worked example
Worked example
Food 30,000, beverage 10,000, and labor 35,000 give prime cost of 75,000.00.
Prime cost = food cost + beverage cost + total labor cost.
Supported inputs
Precision and limits
Visible input limits
Fixed decimals accept up to 30 digits and 12 decimal places and are capped at an absolute value of 1e12 per input. Rates are capped at 1000%; percentage shares and method-specific domains may be narrower.
International scope
No currency, tax jurisdiction, accounting framework, payroll rule, marketplace fee schedule, financing term, or industry benchmark is selected automatically.
Decision boundary
Use the result to relate entered traffic, capacity, sales, stock, labor, seats, rooms, or service time within one clearly bounded operation. Results remain arithmetic scenarios, not accounting records, forecasts, valuations, legal interpretations, professional advice, or recommendations.
Calculator-specific assumptions
This is a scenario from visitor-entered values. Keep currencies, periods, accounting classifications, and operating definitions consistent. It is not accounting, tax, legal, investment, or business advice.
