How to use the billable hours calculator
Enter total hours worked, billable hours, your billing rate and an optional collection percentage. WorkTimeCheck calculates billable utilization, non-billable hours, billable value and estimated collected revenue.
If 30 of 40 worked hours are billable at $100 per hour, billable utilization is 75% and the billable value is $3,000.
Billable utilization formula
Billable utilization equals billable hours ÷ total hours worked × 100. If 30 of 40 hours are billable, utilization is 75%. The remaining 10 hours are shown as non-billable time.
Billable value and collection estimate
Billable value equals billable hours × billing rate. A separate collection percentage can be used for a simple revenue estimate. For example, 30 billable hours at $100 per hour creates $3,000 of billable value; at a 90% collection estimate, that corresponds to $2,700.
What billable hours do not measure
Utilization is only one business metric. This calculator does not determine profitability, realization, write-offs, expenses, taxes or whether particular work should be billed to a client. Use the definitions and billing rules appropriate to your profession and engagement.
