Utilization rate calculator
Utilization rate is billable hours divided by available hours. Available hours are the hours a person is expected to work in a year, less paid time off and holidays. Enter a normal week and the time off, and the calculator returns annual utilization and the billable hours per week a target needs.

Common questions
- Most firms leave paid time off and holidays out of available hours, so a person is not measured against weeks they were never expected to work. Whichever way you choose, use it for everyone and every period, or the numbers will not compare.
- Principals spend more of their time on business development, management and mentoring, which is necessary and not billable. A single firm-wide target treats that work as a shortfall.
- No. The calculator runs in your browser. Nothing you type is sent anywhere or stored.
