Labor Cost Calculator

Labor is the single largest controllable expense in QSR operations, typically accounting for 22-33% of gross revenue. Unlike rent or franchise royalties, labor costs can be actively managed through scheduling, training, technology, and retention strategies. This calculator helps you model your current staffing structure and identify opportunities for improvement.

Labor Cost Percentage vs. Prime Cost

Your labor cost percentage tells only half the story. Industry operators focus on prime cost, which combines food cost and labor cost into a single metric. Most successful QSR operators keep prime cost below 60% of revenue. If your food cost runs 30% and labor is 28%, your prime cost is 58%, leaving 42% for occupancy, overhead, and profit.

Why Sales Per Labor Hour (SPLH) Matters

SPLH is the metric that top QSR operators track most closely. It measures the revenue generated for every hour of labor scheduled. A high SPLH during peak hours (lunch, dinner) indicates efficient staffing. A low SPLH during off-peak periods suggests overstaffing. The goal is not to minimize labor hours but to maximize the revenue each hour produces.

Most QSR concepts target $35-55 in SPLH, with higher-volume locations and drive-thru-heavy formats trending toward the upper end. Track SPLH by daypart (breakfast, lunch, dinner, late night) to identify your biggest scheduling opportunities.

The True Cost of Labor: Beyond Wages

The hourly wage you pay employees is just the starting point. Employer-paid payroll taxes (Social Security, Medicare) add 7.65% on top of gross wages. Workers' compensation insurance, which is mandatory in most states, adds another 2-4% for restaurant operations. If you offer benefits like health insurance or paid time off, that adds another 3-8%.

This means a $15/hour employee actually costs $16.50-$17.50/hour when you include burden costs. The calculator above lets you toggle these costs on or off to see the impact on your total labor percentage.

Managing Overtime in QSR

Overtime is one of the most common labor cost leaks in QSR operations. Federal law requires 1.5x pay for hours exceeding 40 per week (some states, like California, also require daily overtime after 8 hours). A single shift manager working 50 hours per week at $17/hour costs an extra $127.50 weekly in overtime premium, or $6,630 annually.

The solution is cross-training. When multiple employees can fill multiple positions, you gain the scheduling flexibility to keep everyone under the overtime threshold without sacrificing coverage.
