Your hourly rate is more than wages
Client hours must also fund taxes, overhead, unpaid admin time, vacation, and enough profit to keep the business resilient.
How it works
- Set the annual take-home income you want after estimated tax.
- Enter realistic billable hours and vacation weeks.
- Add overhead, non-billable time, and a profit buffer.
Labor rate formula
- Annual billable hours = billable hours per week × working weeks.
- Minimum revenue adjusts take-home income for tax, overhead, and non-billable capacity.
- Recommended rate = yearly gross target ÷ annual billable hours.
Common labor-rate mistakes
- Using personal wage as the client charge-out rate.
- Assuming every working hour can be invoiced.
- Leaving overhead or profit at zero because they are not direct job costs.
Frequently asked questions
How do contractors calculate an hourly labor rate?
Start with required annual take-home income, account for tax, overhead, non-billable time and vacation, then divide required revenue by realistic billable hours.
Why is my charge-out rate higher than my wage?
A client-paid hour must also fund insurance, tools, vehicles, administration, quoting, unpaid time, tax, and profit.
How many billable hours should I expect?
It varies by trade. Independent contractors rarely invoice every working hour because sales, travel, purchasing, and administration consume time.
Should profit be included in a labor rate?
Yes. A rate that only replaces wages and costs leaves no buffer for risk, growth, equipment replacement, or slow periods.
