OEE Calculator
Calculate availability, performance, quality, and overall equipment effectiveness for a production run.
Formula
OEE = availability x performance x quality; availability = run time / planned production time; performance = ideal cycle time x total count / run time; quality = good count / total count.
About the OEE Calculator
Calculate availability, performance, quality, and overall equipment effectiveness for a production run. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the OEE Calculator Works
Planned and actual run time determine availability, the ideal output rate determines performance, and accepted units determine quality before the three factors are multiplied.
Formula
OEE = availability x performance x quality; availability = run time / planned production time; performance = ideal cycle time x total count / run time; quality = good count / total count.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Planned production time (required) - enter in min.
- Actual run time (required) - enter in min.
- Ideal cycle time (required) - enter in s/unit.
- Total units produced (required).
- Good units produced (required).
Results Reported
The result panel reports the final answer and the intermediate quantities needed to check the calculation:
- Availability (%)
- Performance (%)
- Quality (%)
- Overall equipment effectiveness (%)

Accuracy and Limitations
Use consistent time units and an achievable ideal cycle time. Planned shutdown definitions, speed losses, scrap rules, and changeovers should follow the site's OEE standard.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
