Labor Cost Calculator (+ Percentage)

Labor cost percentage formula

Labor cost % = total labor cost ÷ total revenue × 100. Example: $15,000 of labor in a month with $50,000 of sales is $15,000 ÷ $50,000 × 100 = 30%. Put another way, every $1 of labor brought in $3.33 of revenue.

Formula for total labor cost

Total labor cost = gross wages + employer payroll taxes + benefits + workers comp. Example: 2 staff working 160 hours each at $18 per hour earn $5,760.00 in wages. Employer Social Security and Medicare (7.65%) add $440.64, so labor cost before benefits is $6,200.64. Use this loaded figure in the calculator, not wages alone, or the percentage will look better than it really is.

Labor cost percentage: the operator's vital sign

Labor % = total loaded labor ÷ revenue. A restaurant doing $48k a month on $15.5k of labor runs 32.3%, inside the 28% to 33% restaurant band, catastrophic for retail, and luxurious for a consultancy. The percentage only means something against your industry's benchmark, which is why the calculator puts them side by side and prices the gap in dollars.

Loaded labor or the number lies

Wages alone understate labor by a quarter. Count employer payroll taxes (7.65%+), workers comp, benefits, and payroll for salaried managers, plus your own draw if you work the floor. The employee cost calculator builds the loaded figure per person; sum them here.

Moving the percentage

Two levers, and the denominator is usually stronger: revenue per labor hour (pricing, upsells, throughput) beats hour-cutting, which hits service and revenue in a spiral. Where hours are the problem it's rarely headcount; it's schedule shape: overtime creep (see the overtime calculator), full staffing through dead hours, and no demand-based scheduling. A 2-point improvement on $50k/month is $12k a year of pure margin.

How labor cost percentage is calculated

Industry benchmarks by sector

Labor cost percentage targets vary sharply by industry. Full-service restaurants average 30% to 35% of revenue; fast-casual operations run 25% to 30%. Retail targets land at 15% to 20%, while manufacturing benchmarks sit around 20% to 25% of cost of goods. Construction trades typically budget labor at 25% to 35% of total project cost, depending on trade complexity. Hospitality housekeeping departments often spike to 40% to 45% because the work is almost entirely manual with near-zero material offset. These figures assume fully loaded labor (wages, payroll taxes, and benefits combined). A raw wage comparison against any of these benchmarks will understate true cost by 20% to 30% in most jurisdictions.

What this calculator does not cover

This tool evaluates direct labor percentage against revenue benchmarks. It does not allocate indirect administrative salaries, temp agency recruitment premiums, or variable workers compensation insurance tiers. For a full breakdown of what one worker costs the business including PTO accrual and payroll taxes, run those figures through the employee cost calculator first, then feed the loaded total here.

Overtime as a percentage distortion

Hours worked beyond 40 per week under the Fair Labor Standards Act must be compensated at 1.5× the regular rate. A technician at $22/hr straight time costs $33/hr in overtime, a 50% increase in unit labor cost for those hours. If that technician works 45 hours in a week, the blended hourly rate rises to $23.22, a 5.5% cost increase that the calculator will correctly capture only if you input total wages paid, not hours × base rate. Some states, including California, impose daily overtime after 8 hours and double time after 12 hours, compounding this effect further. Use the overtime pay calculator to determine total wages before entering them here.

Break-even intersection

Labor cost percentage and break-even analysis are directly linked. If fixed costs are $18,000/month and variable costs (including a 32% labor rate) consume $0.58 of every revenue dollar, the contribution margin is $0.42. Break-even revenue equals $42,857/month. Dropping the labor percentage to 28% widens the margin to $0.46, cutting break-even to $39,130, a $3,727/month reduction in required sales. That sensitivity makes labor percentage the highest-leverage variable in most service businesses. The break-even point calculator lets you model these shifts interactively once you have a reliable labor cost figure.
