Prime Cost Calculator

The two costs you control daily.

Prime cost — cost of goods sold plus total labor — is the single best health metric for a restaurant, because it covers the two expenses management actually controls day to day. This calculator combines your food and beverage COGS with fully-loaded labor (wages, payroll taxes, benefits) and scores the result against industry benchmarks.

Why people use this

Operators use it as the monthly health check — COGS plus labor against the 60–65% benchmark tells you whether the problem is the kitchen, the schedule, or neither. Lenders and franchise reviewers ask for prime cost before almost anything else.

How it works

  1. Enter food COGS and beverage COGS for the period (from the food cost calculator or your P&L).
  2. Enter total labor including payroll taxes and benefits, not just gross wages.
  3. Enter total sales for the same period.
  4. Read prime cost %, the COGS and labor splits, and what is left for rent, utilities, and profit.

Common questions

What is a good prime cost for a restaurant?

The classic benchmark is 60–65% of sales for full-service restaurants; profitable quick-service operations often run 55–60%. Above 65% there is rarely enough left for occupancy costs, utilities, and profit — at 62% prime on $55,000 of sales, $21,000 covers everything else.

Should labor include payroll taxes and benefits?

Yes. Labor is fully loaded: wages, employer payroll taxes, workers' comp, benefits, and staff meals. Using gross wages alone understates labor by roughly 15–25% and makes prime cost look healthier than it is.

Which lever matters more — COGS or labor?

Whichever is further from its benchmark. Food cost problems respond to portioning, waste tracking, and menu engineering; labor problems respond to scheduling against forecast sales, not habit. Fix the bigger gap first — one point of prime cost on $55,000 of monthly sales is $550 a month.
