Plumbing Technician Utilization: Define the Hours First
A utilization percentage is only meaningful when both hour categories are defined. This guide calculates billable job hours divided by available work hours. It does not measure workmanship, customer outcomes, or the full value of necessary travel, training, and administrative work.
In this guide
State which utilization measure you use
Businesses use “utilization” to describe different ratios. Some compare assigned hours with available hours; others compare billable time with paid time. Write the exact formula beside the result.
For this worksheet, use billable job hours divided by available work hours over the same period. Define whether available hours exclude leave, holidays, or other categories, and apply the rule consistently.
Do not compare your figure with another business or period that uses a different denominator.
Use the hours calculator
Enter hours from the same person or team and the same reporting period. The calculator expects billable hours to be a subset of the entered available hours. If your billing units can exceed actual work hours, this particular definition is not suitable without changing the measure.
A fictional technician with 28 billable job hours out of 40 available work hours has a billable-hours share of 70%. That leaves 12 hours in other defined categories; it does not prove those hours were wasted.
Keep necessary nonbillable work visible
| Time category | Review question |
|---|---|
| Travel | Was the schedule practical for the service area? |
| Material collection | Was the need known before dispatch? |
| Training | Was this planned capability-building time? |
| Job documentation | Was the work necessary for a reliable handoff? |
| Waiting | What prerequisite or decision caused the delay? |
| Unassigned time | Was demand, staffing or scheduling the constraint? |
Treat these as categories to understand, not automatic reasons to criticize a technician. Some nonbillable work supports safe, accurate, and reliable service.
Avoid turning the percentage into a quality target
A higher billable share does not establish better workmanship or customer outcomes. Pressuring staff to classify all time as billable can make the report less trustworthy.
There is no universal ideal percentage supplied by this calculator. The useful comparison is between consistently defined periods with enough context to explain the differences.
Review overtime, leave, changing team composition, and unusual jobs separately so a percentage does not hide important workload changes.

Reconcile the categories to the underlying records. Overlapping entries, missing travel time, or inconsistent start/stop habits can distort the calculation before any scheduling conclusion is made.
Use the result to improve the system
Investigate repeatable causes such as missing parts, unclear handoffs, or avoidable schedule gaps. Test whether a process change improves the underlying issue rather than focusing only on the percentage.
GoPlumber's schedule and job records can provide context, but do not assume native time tracking or utilization reporting is available. This article provides an independent definition and calculator whose inputs must come from reliable records.
