What this calculator measures
Billable hours remove administrative and other non-client time from total hours; utilization expresses the billable share.
Formula
Billable = Total - Non-Billable; Utilization % = Billable / Total x 100
Worked example
- 1A 40-hour week contains 12 non-billable hours.
- 228 hours are billable and utilization is 70%.
How to interpret the result
Higher utilization is not automatically healthier if sales, administration, and recovery time are neglected.
Common mistakes and limits
- Counting unapproved time as billable, omitting internal meetings, or setting non-billable hours above total hours.
Frequently asked questions
