Technician utilization
Technician utilization is the percentage of a technician's available paid hours that are billed to customer work, calculated by dividing billable hours by total scheduled or paid hours over a period.
The inputs.
- Billable hoursHours billed to customer work — time-and-materials and agreement-covered visits; training, vehicle maintenance, and unpaid downtime excluded.
- Total paid hoursPaid (or scheduled available) hours for the same period — the denominator utilization is measured against.
- Read withWrench time, which measures hands-on-tool hours rather than billable hours.
How to read technician utilization.
How to calculate technician utilization
Technician utilization equals billable hours divided by total paid (or scheduled available) hours for the same period. What counts as "billable" is a policy decision — most contractors include time-and-materials work and agreement-covered visits, and exclude training, vehicle maintenance, and unpaid downtime, though some also count warranty work as billable depending on how it's structured against the manufacturer.
Why technician utilization matters for commercial contractors
Utilization is the direct link between headcount and labor cost recovery — it's the number that tells an operations or branch manager whether the shop needs to hire, whether it's overstaffed for current demand, or whether the gap is really a dispatch and scheduling problem rather than a staffing one. Across multiple branches, comparing utilization side by side is often the fastest way to spot a branch that's under-booked or over-committed relative to its crew size.
Utilization vs wrench time — what's the difference
Utilization measures billable hours against paid hours; wrench time measures hands-on-tool hours against paid hours. A technician can be fully utilized (all their time is billed to a job) while still having lower wrench time if a chunk of that billed time goes to travel or paperwork rather than the repair itself. The two metrics are meant to be read together, not as substitutes.
How Thermal tracks technician utilization automatically
Work order timestamps and job assignment data roll up into per-technician and per-branch utilization automatically, without a separate timesheet reconciliation step. Because the same data feeds job costing, utilization and labor cost recovery stay consistent with each other rather than coming from two different systems that can drift apart.
Questions attached to this term.
What's a good technician utilization target?
It varies by trade, route density, and how much of the day is billable versus administrative — treat published targets as general guidance and track your own trend rather than a fixed benchmark.
Does PM or warranty work count as billable for utilization?
Usually yes for agreement-covered PM work, since it's billed against the agreement even if the customer doesn't see a line-item invoice. Warranty work depends on your reimbursement structure with the manufacturer or distributor.
How does utilization tie into payroll?
Utilization compares billable hours to paid hours, so it directly reflects labor cost recovery — but it isn't a payroll calculation itself; payroll still runs through your accounting system, with Thermal feeding the operational hours data alongside it.
Can technician utilization be compared across branches?
Yes, as long as billable-hour definitions are applied consistently — which is easier when every branch dispatches from the same system instead of separate spreadsheets or regional tools.
