What This Calculator Does
This calculator analyzes your billable hours utilization rate, which measures how efficiently you convert working time into revenue. It shows your effective hourly rate when accounting for all hours worked, not just billable ones.
The Formula
Utilization rate is the percentage of your working time spent on billable client work. Your effective rate divides total billable revenue by ALL hours worked, revealing your true earnings per hour.
Step-by-Step Example
Track total hours
Record all hours worked including admin, marketing, proposals, and learning. Example: 160 hours in a month.
Track billable hours
Record only hours billed to clients. Example: 100 billable hours.
Enter your rate
Your billing rate. Example: $85/hour.
Analyze results
Utilization: 62.5%. Revenue: $8,500. Effective rate: $53.13/hour (your real earning rate).
Real-World Use Cases
Profitability Analysis
Understand if your billing rate is high enough to compensate for non-billable time.
Time Optimization
Identify if too much time goes to admin tasks and find areas to streamline or delegate.
Rate Adjustment
Use effective rate data to justify rate increases to clients.
Common Mistakes to Avoid
Not tracking non-billable hours. If you only track client hours, you cannot accurately assess profitability.
Targeting 100% utilization. You need time for marketing, learning, and admin - 65-75% is a healthy target.
Ignoring the gap between your billing rate and effective rate when assessing your income.
