Idle time is paid technician time that is spent neither working on a job nor traveling between jobs: waiting for access, parts, approvals, a customer or the next assignment.
How to calculate idle time
Idle time is what remains after the measurable parts of the day are taken out:
Idle time = Paid hours − Wrench time − Drive time − Scheduled breaks − Other paid non-field time
From job-level timestamps, the gap between leaving one job and arriving at the next is travel plus idle. Compare it to a realistic drive estimate for that pair of addresses at that hour, and the excess is idle.
Say a gap between jobs is 70 minutes and the drive should take 25. That is 45 minutes idle. Across a day, idle time can come in a few large pieces rather than many small ones.
Why it matters for scheduling
Idle time and drive time both shrink productive hours, but they have different causes and different fixes. Lumping them together hides which problem you have.
Common causes of idle time:
- Padded durations. A job booked for three hours finishes in two, and the next job is not until the original end time.
- Early arrival. The truck reaches the next job before the window opens.
- Waiting on access or parts. The customer is not home, or the part is not staged.
- Cancellations. A gap opens and nothing fills it.
The first two are scheduling problems: better job duration estimates fix them. The last two are often process problems: confirmation calls and parts staging fix them faster than any change to the board. The technician utilization rate post has a table showing how to read idle next to travel and work.
A common mistake
Counting idle time as drive time. If every gap between jobs is called travel, a day with 45 minutes of waiting looks like a routing problem. Teams then work on routes when the real fix is confirming customers the day before.

- Drive time is the other non-work part of the day, with different causes.
- Booked utilization counts idle time inside job blocks as busy.
Common questions
Is idle time the same as downtime?
Mostly. Downtime is sometimes used for equipment or vehicles being out of service. Idle time usually refers to a technician who is paid and available but not working.
How do I reduce technician idle time?
Find the cause first. Use realistic job durations, confirm appointments, stage parts before the day and fill cancellation gaps with flexible work.
Should lunch count as idle time?
No. Scheduled breaks are excluded from the calculation. Idle time is unplanned waiting.
