Billable Hours Calculator
Measure how much of your time is billable. Enter your total hours and the hours you can bill, and the calculator returns your utilization rate, your non-billable hours and, if you add a rate, the revenue.
How to calculate billable hours utilization
- Enter the total hours available or worked in the period.
- Enter how many of those hours are billable.
- Add your hourly rate to also see revenue, then read your utilization rate.
Examples
120 billable of 160 total at 150 per hour
totalHours: 160, billableHours: 120, hourlyRate: 150
75% utilization, 40 non-billable hours, revenue 18,000
Frequently asked questions
How is the utilization rate calculated?
Divide billable hours by total hours and multiply by 100. If you billed 120 of 160 hours, that is 120 / 160 = 0.75, or 75 percent utilization. The rest are non-billable hours.
What is a good billable utilization rate?
It varies by role and industry. Many agencies and consultancies target somewhere around 70 to 90 percent for billable staff, leaving time for admin, sales and training. Use your own target as the benchmark.
What counts as non-billable time?
Hours you cannot bill to a client: internal meetings, admin, business development, training and breaks. The calculator shows these as total hours minus billable hours.
How is revenue worked out?
Revenue multiplies your billable hours by your hourly rate. At 120 billable hours and 150 per hour that is 18,000. The rate is optional, so you can also use the tool for utilization alone.
