How to use the billable hours calculator
- 1
Enter the known information

- 2

- 3
Review the complete result
Check the main answer, supporting values and method before copying, downloading or acting on the result.
What makes this tool more useful
Measure the share of work time that produces revenue and calculate what a target requires. The result separates capacity from actual billable hours.
How the calculation works
Utilization divides billable hours by total working hours. Revenue projections use billable time only and account for selected working weeks.
Plan agency capacity, freelance targets or professional-services workloads.
Private, fast and mobile-ready
The workspace runs with browser JavaScript and does not submit entered values to a Rantey calculation endpoint. Controls use readable labels, large touch targets and responsive result panels for narrow screens.
