What are good benchmark values for maintenance KPIs?
Widely cited maintenance KPI targets are: reactive maintenance below 20 to 30 percent, planned work above 80 to 90 percent, wrench time around 50 percent or higher, schedule compliance around 90 percent, PM compliance around 90 percent, a ready backlog of 4 to 6 crew-weeks, and OEE around 85 percent for world-class discrete manufacturing.
These are the benchmark target ranges most commonly cited across reliability and maintenance practice. They are orientation, not absolutes: the right target depends on sector, asset criticality, and operating context. Use them to see roughly where you stand, then measure your own figures.
| Metric | Best-practice target | Warning sign |
|---|---|---|
| Reactive maintenance % | Below 20 to 30% | Above 50% |
| Planned work % | 80 to 90%+ | Below 60% |
| Wrench time | ~50% or higher | Below 30% |
| Schedule compliance | ~90%+ | Below 70% |
| PM compliance | ~90%+ | Below 80% |
| Ready backlog | 4 to 6 crew-weeks | Growing without bound |
| OEE (discrete mfg) | ~85% world-class | 40 to 60% common |
Ranges on this page are practitioner estimates drawn from operational experience across heavy industry, provided for orientation. Your actual figures will differ. The Diagnostic measures them against your own CMMS and downtime data.
