PM completion rate
PM completion rate is the percentage of scheduled preventive maintenance visits that are actually completed within their due window, out of all PM visits scheduled for a period.
The inputs.
- PM visits completed on schedulePreventive maintenance visits completed within their due window, with the required inspection tasks actually recorded.
- PM visits dueAll PM visits due in the period — the denominator completion rate is measured against.
- Grace windowA slip allowance tied to visit frequency — a few days for a monthly PM, wider for quarterly or annual visits, before a visit counts as missed.
How to read PM completion rate.
How to calculate PM completion rate
PM completion rate equals PM visits completed on schedule divided by total PM visits due in the period. "On schedule" is typically defined by a grace window tied to the visit frequency — a monthly PM might allow a few days of slip, while a quarterly or annual visit might allow a wider window before it's counted as missed rather than late.
Why PM completion rate matters for commercial contractors
Every agreement with PM coverage is a promise to perform those visits, and a low completion rate is both a liability exposure — if a covered piece of equipment fails and the PM history shows missed visits — and a renewal risk, since facilities managers increasingly ask for PM completion evidence before signing again. It's also a leading indicator for callback rate and equipment failure, since deferred PM work tends to show up later as reactive calls.
PM completion rate vs PM compliance rate
Completion rate answers "did we do the PM visits we scheduled" — it's about execution against a schedule. Compliance rate answers "is the covered equipment currently up to date" — it's a point-in-time status of the asset itself. A shop can have a strong completion rate this month while still carrying non-compliant equipment from a prior gap that was never caught up.
How Thermal tracks PM completion rate automatically
PM visits generated from a service agreement's schedule are tracked against their due window automatically, and completion rate rolls up by branch, technician, or agreement without a manual log. Missed or at-risk visits surface on the dispatch board before the window closes, rather than being discovered during a renewal audit.
Questions attached to this term.
How is PM completion rate different from PM compliance rate?
Completion rate measures whether scheduled visits were performed on time — an execution metric. Compliance rate measures whether covered equipment is currently up to date — a status metric. They're related but answer different questions.
What counts as a "completed" PM visit?
A visit performed within the grace window defined for that PM frequency, with the required inspection or maintenance tasks actually recorded — a visit logged but with incomplete checklist items typically isn't counted as fully completed.
How do missed PMs affect agreement renewal?
A pattern of missed PM visits is one of the most common reasons a commercial customer doesn't renew, since it undermines the core value proposition of the agreement — predictable, proactive maintenance instead of reactive repair.
Can PM completion rate be viewed across multiple branches?
Yes, when every branch schedules PM visits from the same agreement data instead of separate local processes, which is what makes a company-wide rollup meaningful rather than an apples-to-oranges comparison.
