Labor cost percentage is the sum of gross wages, salaries, payroll taxes, and benefits for a period, expressed as a percentage of total sales for that period.
Formula: Labor cost % = (Wages + Salaries + Payroll Taxes + Benefits) ÷ Total Sales × 100
For full-service independent restaurants, the operational target band is 28–35% labor cost. The National Restaurant Association's 2024 Restaurant Operations Data Abstract reports a full-service median of 36.5% in 2024; the profitable-operator subset ran 34.2%. Limited-service ran a median of 31.7%.
Push below 28% and service quality typically suffers — the schedule is too tight to absorb a single call-out without overtime or a missed shift. Stay above 35% and operating margin is squeezed before the rest of the P&L is calculated.
The most common operator mistake is reporting "labor cost" as gross wages only. True labor cost includes the full burden:
Net: indies without health/401k run at 1.15–1.20× gross wages. Operators offering benefits run at 1.20–1.30×. Reporting only gross wages systematically understates labor cost by 3–7 percentage points.
Example: $40,000 weekly sales, $11,500 gross wages, $1,725 burden (15% layered on). Labor cost = ($11,500 + $1,725) ÷ $40,000 × 100 = 33.1% — inside the operational band.
Plug in your weekly numbers. The calculator computes labor cost percentage with the proper burden multiplier and flags the result against the NRA-aligned operational band.
Inside the operational target band (28–35% full-service).
Reference: NRA 2024 full-service median 36.5%; profitable-operator subset ran 34.2%.
