What is prime cost?

Prime cost combines your cost of goods sold and your total labor cost, then expresses the total as a percentage of sales. It's considered the single most important number in restaurant finance because food and labor together typically make up 60-70% of every dollar you take in.

Prime Cost % = ((Food Cost + Labor Cost) ÷ Total Sales) × 100

What's a good prime cost percentage?

Most full-service restaurants aim for 60-65%, quick-service often targets closer to 55-60%, and anything above 70% usually signals a cost or pricing problem that needs attention. Unlike food cost or labor cost alone, prime cost gives you room to balance the two — a slightly higher labor cost is fine if food cost is well controlled, and vice versa.
