What is a healthy restaurant prime cost percentage?

For most full-service concepts, healthy prime cost runs 55-60% of sales. 60-65% is a watch zone where small leaks compound, and above 65% prime cost is eroding the margin that should cover rent, overhead, and profit.

How do you calculate restaurant prime cost?

Add cost of goods sold (food plus beverage) to total labor (wages, payroll taxes, and benefits) for the same period, then divide by net sales and multiply by 100. Example: $34,000 COGS + $31,000 labor on $100,000 in sales = 65% prime cost.

Restaurant Prime Cost: How to Calculate, Benchmark & Fix It

Prime cost (your cost of goods sold plus labor) is the clearest single signal of whether a restaurant is built to keep its profit. Here’s how to calculate it, what it should be in 2026, and how San Diego operators bring it back down.

The formula

What Is Restaurant Prime Cost?

Restaurant prime cost is the sum of a restaurant's cost of goods sold (food and beverage) and total labor (wages, payroll taxes, and benefits), expressed as a percentage of sales. It is the single most important controllable cost metric, and most full-service restaurants aim to keep it between 55% and 60%.

The threshold

Why Prime Cost Above 65% Signals Trouble

For most full-service concepts, healthy prime cost runs 55–60% of sales. The 60–65% band is a watch zone where small leaks compound. Above 65%, prime cost is consuming the margin that should cover rent, overhead, and profit — and under 2026 wage and rent pressure, that gap rarely closes on its own.

How to Calculate Prime Cost

Add food and beverage COGS for the period, add total labor for the same period, then divide by net sales. Example: on $100,000 in sales with $34,000 COGS and $31,000 labor, prime cost is $65,000 — or 65%. That one percentage tells you more about the health of the business than almost any other line.

The discipline is consistency: same period boundaries and the same definition of labor every time. Most operators who think their food cost is fine are comparing inconsistent periods or leaving payroll taxes out of labor. Run it the same way monthly and the trend becomes your early-warning system.

Add COGS. Total food + beverage cost for the period.
Add labor. Wages + payroll taxes + benefits for the same period.
Divide by net sales. (COGS + labor) ÷ sales × 100 = prime cost %.

Benchmarks

Prime Cost Benchmarks by Concept (2026)

Full-service: 55–60%. Quick-service: 55–62%, where lower food cost is offset by a higher labor ratio. Bars run lower COGS but live or die on pour-cost variance. Fine dining often pushes 65%+ by design, trading prime cost for check average and experience. Benchmarks are a starting line, not a verdict — your concept and market set the real target.

Concept	Healthy Prime Cost	Note
Full-service	55–60%	Balanced COGS and labor
Quick-service	55–62%	Lower food cost, higher labor ratio
Bar / high-volume	50–58%	Watch pour-cost variance
Fine dining	60–65%+	Higher by design; check average offsets

Prime Cost	Status	What it means
≤60%	Healthy	Margin to protect
60–65%	Watch zone	Small leaks compound
>65%	Bleeding	Profit erosion — fixable

How to lower a high prime cost

You don't cut prime cost with across-the-board reductions — you find the specific points leaking and close them. The usual suspects: theoretical-vs-actual food variance from over-portioning and waste; labor scheduled to a weekend pattern on slow weekdays; pour cost drifting above spec; and a menu mix that pushes your lowest-margin items. Fix those four and most operators recover two to four points without touching a single guest-facing price.
