Key takeaways
Planned maintenance percentage (PMP) is a maintenance KPI that measures the share of total maintenance hours spent on planned, scheduled work. It is calculated as planned maintenance hours divided by total maintenance hours, multiplied by 100. A world-class PMP benchmark is 85% or higher, signalling a proactive, reliability-led operation rather than a reactive one.
Planned maintenance percentage (PMP) is the proportion of your total maintenance labour hours that were planned and scheduled in advance, rather than performed as reactive, unplanned repairs. It is one of the clearest single indicators of maintenance maturity.
A high PMP means most work is anticipated, resourced, and scheduled before a machine fails. A low PMP means the team is firefighting, reacting to breakdowns as they happen. Because planned work is cheaper, safer, and less disruptive than emergency work, PMP is widely treated as a core reliability KPI alongside metrics like MTBF and MTTR.
PMP is a labour-hours ratio, not a count of work orders. That distinction matters: a single emergency breakdown can consume more hours than a dozen routine inspections, so measuring in hours gives a truer picture of where your team's time actually goes.
The formula is planned maintenance hours divided by total maintenance hours, multiplied by 100.
PMP = (Planned maintenance hours / Total maintenance hours) x 100
Planned maintenance hours include scheduled preventive maintenance, condition-based tasks, planned corrective work, and any job that was scoped, scheduled, and resourced before the technician started. Total maintenance hours are every maintenance hour logged in the period, planned and unplanned combined.
For example, if your team logged 800 planned hours out of 1,000 total maintenance hours in a month, PMP is (800 / 1,000) x 100 = 80%. The formula is confirmed consistently across reliability sources including Fiix and MaintainX.
The biggest source of error is misclassification. If a job that was actually a reactive scramble gets logged as planned, your PMP looks better than reality. Clean, consistent work-order classification is the foundation of a trustworthy number.
A world-class PMP benchmark is 85% or higher. Several reliability sources place excellent programs in the 85% to 95% range, while a PMP of 80% is treated as a solid industry baseline.
Here is how published benchmarks line up:
| PMP range | Interpretation |
|---|---|
| 90% to 95% | World-class, per MaintainX; reliability-led culture |
| 85% to 90% | Excellent; the widely cited 85% world-class threshold |
| 80% | Good; accepted industry baseline |
| Below 80% | Reactive tendency; rising firefighting and cost |
One important caveat: an unusually high PMP can be a warning sign as much as a trophy. If the number sits at the very top of the range while breakdowns continue, some genuinely reactive work may be getting misclassified as planned, or necessary corrective work may be deferred to protect the metric. Treat PMP as a directional indicator, not a target to game.
Benchmarks also vary by industry and asset mix. A continuous-process plant with stable, well-understood equipment can sustain a higher PMP than a job shop with variable demand, so compare your trend against your own history first, then against peers.
PMP matters because planned work is cheaper, safer, and far less disruptive than reactive work. Every hour you shift from emergency repair to scheduled maintenance reduces cost and risk.
Reactive maintenance carries hidden premiums: expedited parts, overtime labour, lost production while the line is down, and the secondary damage that happens when a failure mode develops undetected. Planned work removes most of that premium because parts, people, and procedures are arranged in advance.
PMP also has a direct line to throughput. Unplanned stoppages are a primary driver of lost availability, one of the six big losses that erode overall equipment effectiveness. When PMP climbs, unplanned downtime tends to fall, and the availability component of OEE improves with it.
Finally, a high PMP is a workforce-retention and safety signal. Teams that spend their days on planned tasks work in controlled conditions with the right tools, instead of being pulled into stressful, hazardous emergency repairs.
You raise PMP by converting reactive work into planned work: catch problems earlier, schedule them deliberately, and complete them on time. The practical levers below compound on each other.
Most of these levers depend on one capability: turning a detected problem into a scheduled, resourced work order quickly enough that it never becomes an emergency. That is where a connected CMMS earns its place.
A CMMS raises PMP by generating, scheduling, and tracking planned work automatically instead of relying on memory and spreadsheets. It issues PM tasks on a calendar or meter trigger, assigns them, and records completion, which feeds a clean PMP calculation with no manual tally.
The decisive factor for PMP is how fast a CMMS moves a problem from "detected" to "scheduled and parts-ready." The faster that handoff, the more work stays on the planned side of the ledger.
Fabrico is built around the fault-to-fix loop, which is exactly the mechanism that moves hours from reactive to planned. Fabrico connects to machine PLCs for real-time OEE and uses computer vision to capture the true cause of a stoppage, then turns that fault into a prioritized, parts-ready digital work order on the technician's phone with QR-enforced checklists.
Because the platform unifies real-time monitoring and a full CMMS, a developing problem can be detected, scoped, and scheduled as planned work before it forces an emergency stop. That is the operational behaviour PMP is designed to reward. As an EU-built platform headquartered in Bulgaria, Fabrico also keeps that operational data under EU data residency, a practical trust asset for European manufacturers.

Tracking the reactive to planned maintenance ratio shows whether a maintenance program is actually improving.
The planned maintenance percentage formula is planned maintenance hours divided by total maintenance hours, multiplied by 100: PMP = (Planned maintenance hours / Total maintenance hours) x 100. Planned hours include scheduled preventive, condition-based, and planned corrective work, while total hours are every maintenance hour logged, planned and unplanned combined.
A good planned maintenance percentage is 80% or higher, and a world-class benchmark is 85% or higher. Several reliability sources place excellent programs in the 85% to 95% range. Most reactive plants sit well below 80%, indicating a firefighting culture rather than a proactive one.
Planned maintenance percentage measures how much of your total maintenance is planned, while PM compliance measures whether scheduled preventive tasks are actually completed on time. The two are complementary: world-class operations pair an 85%-plus PMP with PM compliance near 90%, so work is both planned and reliably finished.
Yes. A PMP at the very top of the range while breakdowns continue can signal that reactive work is being misclassified as planned, or that necessary corrective work is being deferred to protect the metric. Treat PMP as a directional reliability indicator, not a number to maximise at any cost.
A CMMS improves planned maintenance percentage by automatically generating, scheduling, and tracking preventive and planned corrective work, and by moving detected faults into scheduled, parts-ready work orders quickly. The faster a problem moves from detected to scheduled, the more hours stay on the planned side of the ledger instead of becoming emergency repairs.
Planned maintenance is cheaper because parts, labour, and procedures are arranged in advance, avoiding the premiums of reactive work: expedited parts, overtime, lost production during unplanned downtime, and secondary damage from undetected failure modes. Raising planned maintenance percentage shifts hours away from these costly emergencies.
