Understanding Performance Rate
How we calculate. Performance % = (ideal cycle × total count) ÷ run time × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Performance Rate case uses ideal cycle time 0.5 and total count 800. Enter the same figures below to reproduce the worked path.
What is Performance Rate?
The OEE performance factor. Captures speed losses and small stops when the machine is “running” but slower than ideal.
- Ideal cycle = theoretical best cycle
- Total count includes good and reject if your standard says so
- Run time matches availability run time
The Formula
Worked Example
Common Use Cases
- OEE build: performance factor
- Speed loss analysis: micro-stops
- Line balancing: rate vs ideal
Pro Tips
- Freeze the ideal rate
- Don’t inflate ideal cycles
- Feed the OEE calculator
Limitations: Performance Rate results are educational manufacturing and lean/TPM planning aids—not process-safety, quality-system, or financial advice. Confirm definitions with your MES/SCADA and quality policies.
FAQ
What if performance exceeds 100%?
Usually the ideal cycle is too slow or counts include rework incorrectly—recheck the standard rate.
What if run time is 0?
Performance is undefined—enter positive run time.
