A useful labor rate starts with productive hours.

Annual wage is only one part of employee cost. Add payroll burden, workers compensation, benefits, PTO, vehicles, tools, and other costs, then divide by productive billable hours. Allocate company overhead across field staff before applying the gross-margin target.

What a contractor labor billing rate needs to cover

An employee's hourly wage is not the same as the company's cost for a billable hour. Employer-paid burden and employee-related costs increase annual cost, while nonbillable time reduces the hours over which that cost can be recovered. This calculator also allocates annual company overhead across field employees' billable hours before applying a desired gross margin.

The practical labor-rate formula

Loaded employee cost ÷ annual billable hours = employee cost per billable hour. Add allocated overhead per billable hour to get break-even hourly cost. Recommended billing rate = break-even hourly cost ÷ (1 − target margin as a decimal).

Worked example

At $30 per hour, 40 hours per week, and 50 working weeks, base annual wages are $60,000. Assume 10% payroll burden ($6,000), 5% workers' compensation ($3,000), $6,000 benefits, $2,000 PTO cost, $3,000 vehicle, and $1,000 tools: loaded cost is $81,000. At 75% utilization, 2,000 × 75% = 1,500 billable hours, or $54 per billable hour. With $90,000 annual overhead and three field employees, allocated overhead is $90,000 ÷ (3 × 1,500) = $20 per hour. Break-even is $74; at a 20% gross margin, $74 ÷ 0.80 = a $92.50 billing rate.

Common estimating pitfalls

  • Utilization is the share of paid working hours that can be billed. Use an assumption grounded in your operation; do not treat every paid hour as a billable hour by default.
  • Enter annual overhead for the company once. The calculator divides it across the entered field-employee count and each employee's billable hours.
  • Keep allowances and burden categories consistent with your records to avoid omissions or double counting.

Frequently asked questions

Why can the billable rate be higher than the wage?

The rate has to recover employer costs, nonbillable time, and the allocated share of company overhead in addition to the wage. The selected target margin then prices above that break-even hourly cost.

What does utilization mean in this calculation?

Utilization is the percentage of scheduled working hours expected to be billable. At 40 hours per week, 50 weeks per year, and 75% utilization, the calculation uses 1,500 billable hours per employee.

How is overhead divided among the crew?

Annual company overhead is divided by the number of field employees times billable hours per employee, producing an overhead amount per billable hour.
