How to calculate machine availability
Machine availability measures what percentage of planned production time a machine was actually able to run — one component of Overall Equipment Effectiveness (OEE).
How the calculation works
Availability = (Run time ÷ Planned production time) × 100.
Example
420 minutes run time out of 480 planned: (420÷480)×100 = 87.5%.
Frequently asked questions
How is Result calculated?

Pro Tips for Machine Availability
- Availability is one of three OEE components (along with performance and quality) — track all three for a complete efficiency picture.
- Unplanned downtime (breakdowns) and planned stops (changeovers) both reduce availability, though they may warrant different improvement approaches.
Common Machine Availability Mistakes to Avoid
- Treating availability alone as a complete efficiency metric, when it's only one of three components that together make up OEE.
