Engineering CalculationOEE Calculator - Overall Equipment Effectiveness
Measure how well a machine or line uses its planned time with Overall Equipment Effectiveness, split into availability, performance and quality.
Open the calculator →Formula
OEE = Availability × Performance × Quality
Availability = run time / planned time; Performance = (ideal cycle time × total count) / run time; Quality = good count / total count
Worked example
Planned 480 min, downtime 60 min, ideal cycle 0.8 min, 450 parts made, 430 good
A = 87.5 %, P = 85.7 %, Q = 95.6 % → OEE = 71.7 %
Where engineers use it
- Daily production reports
- TPM and lean programmes
- Finding the biggest loss on a line
