How it works
- Profit needed = income you want to keep ÷ (1 − your tax set-aside).
- Revenue needed = profit needed + business costs.
- Billable hours = weeks worked × billable hours per week.
- Hourly rate = revenue needed ÷ billable hours.
- This is arithmetic on your own inputs. It does not say what the market pays.
Questions
Why count billable hours instead of working hours?
Time spent on admin, finding work, questions and unpaid rework is real work you do not invoice. Dividing by billable hours only is what makes the rate cover it.
What goes in business costs?
Costs you carry to do the work: software, professional liability and other insurance, continuing education, equipment, memberships and licence fees. Use last year’s actuals if you have them.
Where does the tax set-aside come from?
You choose it. The US self-employed tax set-aside calculator on this site estimates self-employment tax from IRS figures; your income tax rate depends on your whole return.
Does this tell me what to charge?
No. It tells you the rate your own numbers require. What clients will pay is a separate question this tool does not answer.
