What Are Billable Hours?

Billable hours are hours of work that can be charged directly to a client, as opposed to non-billable time spent on administration, marketing, or learning. Freelancers, consultants, and law firms track them closely because income depends on billable time, not total time worked.

Billable Utilization

Utilization rate = billable hours ÷ total hours worked × 100. Rates are often set so that billable hours cover all working time and costs.
