Prime Cost Explained: Food, Beverage, and Labor in One Number
A plain-English guide to prime cost and why new restaurants should review food and labor together from week one.
Updated 2026-06-11 for owners and gms.
Prime cost is the controllable core
Prime cost combines cost of goods sold and labor. For a restaurant owner, it is the operating pressure number that connects purchasing, prep, staffing, sales mix, and service execution.
Review it by service pattern
Weekly totals can hide operational reality. Compare lunch, dinner, catering, wholesale, and event patterns separately so a profitable daypart is not carrying a broken one.
Use it as a conversation, not a verdict
A high prime cost should trigger questions: Did vendor prices change? Did overtime spike? Did prep waste increase? Did a low-margin item become popular? The system should preserve enough context to answer those questions.
