Maintenance program
Planned maintenance percentage calculator
Planned maintenance percentage is the share of your maintenance hours that were planned rather than reactive. It is the clearest single measure of whether a maintenance team is running the equipment or the equipment is running the team.
PMP = Planned maintenance hours ÷ Total maintenance hours × 100
Work scheduled in advance with parts and labor identified
Show the assumptions
- Formula
- PMP = Planned maintenance hours ÷ Total maintenance hours × 100
Hours, not work order counts. Counting jobs treats a two-minute reset and a two-day rebuild as equals, and reactive work skews heavily towards the short jobs.
Planned does not mean preventive. A corrective repair that was scoped, parted and scheduled for next Tuesday is planned work. Work that started because someone walked past a leak is not, even if it was necessary.

How to calculate Planned maintenance %
PMP = Planned maintenance hours ÷ Total maintenance hours × 100
Hours, not work order counts. Counting jobs treats a two-minute reset and a two-day rebuild as equals, and reactive work skews heavily towards the short jobs.
Worked example
- Planned maintenance hours 640 hrs
- Total maintenance hours 1,000 hrs
Planned maintenance % = 64.0%
Reading the result
Planned does not mean preventive. A corrective repair that was scoped, parted and scheduled for next Tuesday is planned work. Work that started because someone walked past a leak is not, even if it was necessary.
Benchmarks
80% to 90% planned is the range commonly cited for a mature program. Below 50% the team is effectively reactive, whatever the PM schedule says on paper.
Planned maintenance % questions
What is the difference between planned and preventive maintenance?
Preventive means the work was triggered by a schedule or a meter reading before anything failed. Planned means the work was prepared before it started, whatever triggered it. A breakdown repair can be planned work if it was scoped and scheduled rather than attacked immediately.
Should I measure in hours or work order counts?
Hours. Reactive work is dominated by short interventions, so a count-based figure flatters a reactive team. The hours are also what you actually pay for.
