The wage is not the labor cost
A cleaner’s wage is the most visible input, but a contract must recover more than productive task time. Employer payroll taxes, workers’ compensation, unemployment insurance, paid leave, benefits, training, uniforms, and nonproductive time may affect the cost of one billable hour.
If a bid multiplies job hours by wage alone, missing costs are absorbed by overhead, reduce margin, or create pressure to rush. A burdened rate makes the estimate more honest before it reaches the customer.
Use wage evidence as an anchor
The U.S. Bureau of Labor Statistics reported a $17.71 median hourly wage for janitors and building cleaners in May 2025. Workers in services to buildings and dwellings had a $17.21 median. These are national references, not recommendations for a specific city or contract.
Use the wage required to recruit and retain the job’s crew. Account for shifts, unions, prevailing wage, healthcare, background checks, and customer requirements. National data cannot override local law or a labor agreement.
Separate burden components
Begin with employer payroll taxes and required insurance. Add expected paid leave, health or retirement benefits, bonuses, and other compensation. Then include paid activity that supports service but is missing from productive task minutes.
BLS reported that benefits represented 30.1% of total private-industry compensation in March 2026. That broad figure includes industries unlike many cleaning companies, so it provides context rather than a default percentage.
Calculate a burdened hourly factor
One method divides expected annual employer labor cost by productive annual hours. Another applies a burden percentage to wage for early planning. At an $18 wage and 25% modeled burden, the burdened rate is $22.50 before supplies and overhead.
The productive-hours method reveals how holidays, leave, training, meetings, and utilization reduce hours available for customer work. Document the method so costs are not duplicated later.
Keep supervision and overhead visible
Decide whether site supervision is direct labor, a job line, or overhead, and apply the rule consistently. Operations management, estimating, accounting, sales, insurance, software, vehicles, and office costs also need a deliberate allocation.
Avoid hiding every expense inside one labor multiplier. A separated model lets estimators update wage, benefits, supervision, and overhead without accidentally charging an item twice.
Test wage and productivity together
A lower wage does not guarantee a lower delivered cost if turnover, retraining, absence, or slower production increases hours. A higher hourly wage with stable staffing and stronger output can produce a more reliable contract.
Pressure-test overtime, coverage, wage increases, and slower production. After launch, compare budgeted labor with payroll and timekeeping results. Feed the difference into the next estimate and into any necessary scope review.
Keep recruiting, onboarding, relief coverage, and supervisor time visible even when they are not charged directly to one visit. Consistent classification makes contract comparisons meaningful and shows whether a wage decision changes total labor economics rather than merely moving cost between categories.
