Contractor field notes
An employee’s wage is not their full employer cost
Employer payroll burden, benefits, training, and paid nonproductive time can make cost per productive hour substantially higher than the advertised wage. This tool distinguishes paid hours from productive hours and separates employer cost from a customer billing rate.
Annual employment cost divided by productive hours
Annual cost = regular wages + overtime wages + wage-based employer burden + benefits + other annual costs. Paid hours = regular hours/week × paid weeks + overtime hours/week × overtime weeks. Productive hours = paid hours − paid nonproductive hours. Productive-hour cost = annual cost ÷ productive hours.
Worked example
At $30/hour, 40 regular hours/week for 52 weeks costs $62,400. Five overtime hours for 20 weeks at 1.5× adds $4,500. A 20% employer burden on $66,900 wages adds $13,380. With $6,000 benefits and $3,000 other costs, annual employer cost is $89,280. Total paid hours are 2,180; subtract 480 nonproductive hours to get 1,700 productive hours. Cost is $52.52 per productive hour, versus $40.95 per paid hour.
Common estimating pitfalls
- Do not charge paid leave as extra wages if the paid-week wages already include it.
- Apply employer burden to the intended wage base and avoid repeating benefits in both burden and annual costs.
- Do not confuse this employer cost with a selling rate that includes overhead recovery and company profit.
Frequently asked questions
What is paid nonproductive time?
Paid leave, training, meetings, or other paid hours without project production. It reduces the productive-hour denominator; wages for those hours are already included in total paid wages.
Should I use the productive-hour rate in the employee-versus-subcontractor tool?
That tool asks for a paid-hour cost and applies a separate efficiency factor. Use this tool’s paid-hour cost there, or use 100% efficiency with a carefully aligned productive-hour cost, to avoid counting downtime twice.
Does it determine legally required overtime or payroll taxes?
No. Enter applicable rates and eligible hours after checking your payroll rules. It does not determine exemptions, statutory rates, wage thresholds, or worker classification.
