How to Calculate Billable Hours

What is Billable Hours?

A billable hours calculator converts tracked time into billable amounts and computes monthly revenue at different hourly rates. Attorneys, consultants, and freelancers use billable hour tracking; typical billing efficiency (realization rate) is 85–90% — not all hours worked are billed or collected.
