Maintenance KPI Calculators
Calculate key performance indicators to measure and improve your maintenance operations.
Overall Equipment Effectiveness (OEE)
Measures how well a manufacturing operation is utilized compared to its full potential, combining availability, performance, and quality.
OEE = Availability × Performance × Quality
Equipment Availability
The percentage of time that equipment is available to operate during its scheduled production time.
Availability = (Planned Production Time - Downtime) / Planned Production Time
Mean Time Between Failures (MTBF)
The average time that a repairable asset operates before it fails. A higher MTBF indicates better reliability.
MTBF = Total Uptime / Number of Failures
Mean Time To Repair (MTTR)
The average time it takes to repair a failed asset, from the moment of failure to when it returns to service.
MTTR = Total Downtime / Number of Failures
Mean Time To Failure (MTTF)
The average lifespan of a non-repairable asset. Used to predict when an asset will need to be replaced.
MTTF = Total Hours of Operation / Total Number of Units
Planned Maintenance Percentage (PMP)
Find out how much of your maintenance work is planned vs. reactive. Improve scheduling and reduce emergency repairs.
PMP = (Planned Maintenance Hours / Total Maintenance Hours) × 100
Wrench Time
The percentage of a technician's day that is spent directly working on assets (hands-on maintenance).
Wrench Time = (Direct Maintenance Time / Total Work Time) × 100
Schedule Compliance
Measures the percentage of scheduled maintenance work that was completed within the scheduled week or period.
Schedule Compliance = (Completed Scheduled Tasks / Total Scheduled Tasks) × 100
