Planned Maintenance Percentage (PMP) Calculator

PMP = (Planned Maintenance Hours / Total Maintenance Hours) x 100
Your Planned Maintenance Percentage (PMP) is: 0%

What is PMP?

Planned Maintenance Percentage (PMP) is a key metric used to evaluate the effectiveness of your preventive maintenance program. It tells you what proportion of your total maintenance effort is dedicated to planned activities.

In simpler terms, PMP indicates how well you're sticking to your maintenance schedule and proactively addressing potential equipment issues before they snowball into breakdowns.

Example: Wind Energy Industry


A wind farm operator strives for a high PMP to minimize downtime and maximize energy production.

PMP Calculation

Let's say the maintenance team spends 120 hours per month on scheduled inspections, lubrication, and minor repairs (planned maintenance) and another 40 hours on emergency repairs due to unexpected failures. Their PMP would be:

(120 planned hours / 160 total hours) x 100 = 75%


This 75% PMP indicates a well-structured preventive maintenance program that catches most potential issues before they escalate into major breakdowns. However, there's still room for improvement. The wind farm operator could:

Analyze maintenance data to identify components prone to failure and adjust preventive maintenance schedules accordingly.
Invest in remote monitoring technologies to detect early signs of trouble and schedule maintenance before failures occur.

How to Calculate Planned Maintenance Percentage (PMP)?

The formula for PMP is straightforward:

PMP = (Planned Maintenance Hours / Total Maintenance Hours) x 100

Planned Maintenance Hours:

This includes all the time spent on scheduled maintenance tasks like inspections, lubrication, adjustments, and minor repairs.

Total Maintenance Hours:

This represents the total time your maintenance team spends on all maintenance activities, including planned and unplanned work (corrective repairs, emergency fixes).

If your maintenance crew logs 200 hours in a month, with 160 hours dedicated to planned maintenance tasks (lubrication, filter changes, etc.), your PMP would be:

(160 planned hours / 200 total hours) x 100 = 80%

Factors Affecting Planned Maintenance Percentage (PMP)
