Billable utilization

Billable utilization measures what fraction of paid technician hours are actually billable to customers. The calculation: billable hours / total paid hours.

A tech paid for 40 hours per week who bills customers for 28 of those hours has 70% billable utilization. The remaining 12 hours are typically: drive time between jobs, returning to the shop for parts, administrative tasks, lunch and breaks, and idle time waiting for the next job.

Healthy utilization in residential service: 60-75%. Numbers above 75% suggest aggressive scheduling that may be sacrificing customer experience or tech satisfaction. Numbers below 55% suggest meaningful operational drag — typically either dispatch inefficiency, parts-supply chain problems, or insufficient demand to fill the schedule.

For service operators, billable utilization tracking surfaces where operational improvements pay back most. Specific levers: reduce drive time (better routing, geographic concentration, on-truck inventory to avoid shop returns), reduce admin time (mobile field app for paperwork rather than after-hours data entry), shorten transition time between jobs (better preparation, faster loadout). Each percentage point of utilization improvement on a 5-tech operation generates roughly $20,000-$40,000 in additional annual revenue at the same labor cost.
