Utilization Rate Calculator
Utilization is the #1 metric agencies optimize for. Compute yours weekly and see how it scales annually.
Calculate your weekly utilization rate by comparing billable to available hours. See how your weekly pace scales annually and where non-billable time goes.
Frequently Asked Questions
What utilization rate is healthy for a service business?
Most agencies target 70 to 80 percent for billable staff. Below 60 percent usually signals a pipeline problem or too much non-billable overhead. Above 85 percent leaves no buffer for proposals, knowledge transfer, or absorbing scope creep without burning people out.
Should non-billable time include internal projects?
Yes. Any hour not invoiced to a client is non-billable, whether it goes to an internal product, a free pitch, a team meeting, or onboarding. Tracking all of it is the only way to see where capacity actually disappears.
How does utilization relate to billable hours and realization rate?
Utilization measures the percentage of available time spent on client work. Billable hours is the raw count. Realization rate then measures what fraction of those billable hours actually became invoiced revenue. High utilization with low realization usually means time is being written off or discounted after the fact.
Why is 100% utilization a red flag, not a goal?
At full utilization there is no slack for proposal writing, onboarding new clients, or unexpected scope changes. Teams that stay at 100% for extended periods either burn out, let quality slip, or both. Most high-performing agencies treat anything above 85% as a trigger to hire or renegotiate scope before delivery suffers.
Which part of this does Teetrack provide?
Teetrack records your own time against projects and marks each entry as billable or non-billable, so the billable hours for this calculator come straight from your records. Available hours depend on your schedule, which Teetrack does not store, so enter them yourself. Each Teetrack account belongs to one person, and there is no team utilization dashboard. The Profitability report's Billable % shows billable hours as a share of recorded hours, not of available hours.
