Billable Hours Calculator
(Utilization Rate Tool)
Calculate your billable utilization rate, non-billable hours, and the true blended hourly rate you're actually earning once every hour worked is counted, not just the ones you invoice.
Step 1 — Time Tracked This Period
Every hour on the clock — client work, admin, meetings, business development
Only the hours you can actually invoice a client for
Calculated Results
Enter total hours worked and billable hours to calculate utilization.
Your Quoted Rate Isn't Your Real Rate
Utilization rate exposes the gap between what you charge per billable hour and what you actually earn per hour worked. A consultant billing $100/hour who only invoices 70% of their working time is really earning a $70 blended rate — the other 30% of the week (admin, proposals, meetings) is unpaid overhead baked into the job.
