About This Tool

Knowing what a developer truly costs per hour is essential whether you're hiring, managing a team, or pricing your own freelance work. This calculator factors in salary, employer-paid benefits, payroll taxes, and actual billable hours to give you an honest number — not just a salary divided by 2,080.

Use our Salary to Hourly Rate Calculator if you want a simpler conversion without benefits and overhead. To see how unpaid admin time erodes your effective rate as a freelancer, try the Hourly Rate Lie Detector. And for teams dealing with legacy code, the Technical Debt Cost Calculator helps quantify the cost of quick hacks and maintenance overhead.

Frequently Asked Questions (FAQ)

Why multiply the true hourly cost by 2.0–2.5 for freelance rates?
Employees receive benefits (health insurance, 401k match, paid time off, payroll taxes) that add 20–40% on top of salary. Freelancers cover these costs themselves and also need to account for non-billable time (marketing, admin, learning), gaps between projects, equipment, and profit margin. A 2.0× multiplier covers basic solopreneur overhead; 2.5× is the agency rate that accounts for additional management and infrastructure.
What is the difference between billable hours and total work hours?
Billable hours are hours you can directly invoice a client or that produce measurable output. Total work hours include meetings, email, training, and other overhead. The calculator assumes you input only your billable hours per week — your actual working hours may be higher. Use a lower billable-hour number if you do a lot of non-billable work.
How should I use this when negotiating a contract rate?
Start with the true hourly cost as your absolute floor (break-even rate). The solopreneur rate (2.0×) is your minimum sustainable rate. The agency rate (2.5×) is what you should target if you want healthy margins. For reference, check your effective rate against our Hourly Rate Lie Detector to see how unpaid hours affect your real earnings.
