What is maintenance overtime percentage?

Quick answer

Maintenance overtime percentage is overtime hours as a share of total maintenance hours. Rising overtime alongside flat output is a classic symptom of a reactive plant, where emergency work fragments the day and pushes jobs past normal hours.

FormulaOvertime % = (overtime hours / total maintenance hours) x 100

Warning signHigh or climbing overtime with flat throughput usually signals a reactive, poorly planned operation.

Why it matters

Overtime is one of the most visible symptoms of poor planning, and it is expensive at premium rates. When overtime climbs without a matching rise in output, it is almost always paying for the disruption that better planning would remove.

How to improve it

Attack the reactive work that drives emergency overtime, plan and schedule properly so jobs fit normal hours, and use overtime deliberately rather than as a default.

Frequently asked questions

Why is maintenance overtime rising at my plant?
The most common cause is a high reactive maintenance share. Emergency work fragments the planned day and pushes work past normal hours, so overtime climbs even when output does not.
