Billable Hours Calculator

How to calculate billable hours?

Billable hours are the time spent on client-related tasks multiplied by the agreed hourly rate. This ensures that every minute spent working on specific deliverables is accounted for in your professional compensation.

Total Billing = Hours × Hourly Rate

Using the calculator: an example

For a project requiring 25 hours of focused work at a rate of $100/hr, the calculation provides a clear financial breakdown.

Step-by-step calculation:

1. Record total hours for the project
2. Enter your professional hourly rate
3. Multiply to find the invoice total
