Formula
Utilization rate formula
Utilization rate = Billable hours ÷ Total available hours × 100.
The higher the rate, the more of your time is being converted into revenue.
Examples
Busy but inefficient
You bill 90 hours out of 160 available.
Utilization rate is 56.25%.
This may mean too much time is being lost to admin or unbillable work.
High utilization
You bill 140 hours out of 160 available.
Utilization rate is 87.5%.
Great in the short term, but it can be hard to sustain every week.
When to use
Use it when checking whether your work week has enough billable time to support your pricing and income goal.
Common mistakes
- Counting all working hours as billable.
- Forgetting admin, sales, and unpaid prep time.
- Treating a very high utilization rate as automatically better without checking burnout risk.
FAQ
What is a good utilization rate?
It depends on the business model, but you usually want a rate that leaves room for admin and rest without starving revenue.
Can utilization be over 100%?
In practice, not for a normal working period. If it happens, the time inputs likely need a second look.
Next step
Need better time and money tracking?
QuickBooks or Xero can help you connect time, invoices, and revenue so your utilization targets are easier to manage.
Recheck the rate whenever your billable schedule changes.
