How do I calculate labor cost percentage?
The formula is straightforward: Total Labor Costs divided by Total Revenue, multiplied by 100. A business with $50,000 in monthly revenue and $15,000 in labor costs has a 30% labor cost percentage.
The math is simple. What trips up most business owners is including all the labor costs. Wages are just the starting point. You also need to add employer payroll taxes, workers’ comp insurance, health insurance contributions, paid time off, bonuses, and any other compensation you provide. Payroll taxes alone add roughly 8% to every dollar of wages before you count benefits.
If you only use base wages in your calculation, you’ll undercount your true labor cost by 15-30% depending on what benefits you offer. That gap matters when you’re comparing your numbers to industry benchmarks or trying to price your services correctly.
Use the same time period for both numbers. Monthly labor costs compared to monthly revenue. Quarterly to quarterly. Mixing March wages with full-quarter revenue produces a meaningless ratio that won’t help you make decisions.
What counts as a healthy percentage varies by industry. Restaurants typically target 25-35%, with quick-service operations on the lower end and fine dining higher. Professional services often run 40-60% because labor is the product being sold. Construction ranges widely based on how much work is subcontracted versus performed by employees.
Track this monthly at minimum. A rising labor cost percentage without corresponding revenue growth signals a problem. Either you’re overstaffed, prices haven’t kept pace with wage increases, or revenue is declining while headcount stayed the same. A bookkeeping service that delivers monthly financials lets you spot these trends before they become emergencies.
When the percentage runs high, the fix depends on the cause. Scheduling inefficiency needs tighter labor management. Wage creep without price increases needs a rate adjustment. Declining sales with flat staffing might mean reducing hours or not replacing departing employees. The numbers tell you something is off. Digging into the details tells you what to do about it.
