How this calculator works
The calculator starts with your desired annual take-home income and business expenses, then grosses up for taxes at your estimated tax rate. It determines the required annual revenue by dividing the after-tax target by (1 minus the tax rate). This revenue requirement is then divided by your expected annual billable hours — accounting for vacation, holidays, sick days, and non-billable admin time. The result is the minimum hourly rate you need to charge, with a recommended buffer to cover sales cycles, client gaps, and unexpected scope changes.
Useful scenarios
- A new freelance writer setting a baseline hourly rate of $65/hour to cover $60K take-home, $8K expenses, 25% taxes, 4 weeks off, and 60% billable utilization.
- A consultant checking whether their current $100/hour rate supports a $120K target income with $15K in tool subscriptions and 30% tax rate.
- A solo developer repricing work from $80/hour to $110/hour after AI tools increase their delivery speed and effective billable output per week.
FAQ
Why is the recommended rate higher than the minimum?
The buffer helps cover sales time, client delays, scope creep, and weeks where billable work is lower than expected.
Should I charge hourly or project-based?
Use the hourly rate as your cost baseline even if you package work as fixed-price projects.
How many billable hours can I realistically expect?
1,200–1,500 billable hours per year is typical for a full-time freelancer. That accounts for vacation (3-4 weeks), holidays, sick days, and non-billable time spent on marketing, admin, proposals, and learning. At 40 hours/week, maximum billable is about 1,500–1,800 hours, but most freelancers fall in the 1,000–1,400 range.
