How should labor cost be calculated as a percentage of sales, and what is a typical benchmark for full-service operations?

• A. Labor cost % = total payroll taxes ÷ gross sales
• B. Labor cost % = (total labor costs including wages, benefits) ÷ gross sales × 100; typical benchmark 20-40%
• C. Labor cost % = (gross sales) ÷ (total labor costs)
• D. Labor cost % is not used in financial analysis

Answer: (B)

The key idea is measuring how much of your revenue is consumed by labor. By expressing labor costs as a percentage of sales, you can see how efficiently you’re staffing relative to what you’re bringing in.

Compute this by taking all labor-related expenses—wages, benefits, payroll taxes, overtime, and other labor costs—and dividing that total by gross sales, then multiplying by 100 to turn it into a percent. This shows, for every dollar of sales, how much is spent on labor.

For full-service operations, a typical benchmark range is about 20% to 40%. This broad range reflects differences in service level, concept, and location. Some high-service environments may sit higher on the scale, while leaner full-service concepts might be toward the lower end. This metric is useful because if labor costs creep above the benchmark, profitability can suffer; if they’re too low, service quality or staffing levels may be inadequate.

Why the other ideas don’t fit: labor cost should include all labor-related expenses, not just payroll taxes; using gross sales divided by labor costs reverses the ratio; and stating that labor cost percentage isn’t used in financial analysis is incorrect because this metric is a fundamental, widely used measure in restaurant finance.
