Frequently Asked Questions
What is billable utilization?
It is the share of available time spent on billable work.
Should vacation be excluded?
That depends on your company methodology.
Is higher always better?
No. Sustainable targets vary by role.
Using Billable Utilization Responsibly
Billable utilization compares billable hours with the available or worked hours used as the denominator. A consultant with 30 billable hours out of 40 tracked hours has 75% utilization. The percentage is only meaningful when teams use the same definition of available time.
Vacation, holidays, training, sales work and internal projects may be included or excluded depending on company policy. For staffing and profitability analysis, document the denominator clearly and compare like-for-like periods rather than treating one utilization percentage as a universal benchmark.
Calculation Method and Interpretation
Billable utilization is billable hours divided by the chosen available-hours base. Using paid hours, workable hours or capacity after leave produces different rates, so teams should keep the denominator consistent when comparing employees or periods.
