How this utilization rate calculator works

Utilization is the share of paid working hours that are actually billable, and small gaps add up fast.

  • Utilization rate = billable hours ÷ available hours.
  • Revenue = team size × hours per week × utilization × billing rate.
  • Revenue gap = revenue at your target utilization − revenue at your current rate.

The annual opportunity is that monthly gap carried across the year.
