How to calculate quality rate
Quality rate measures the percentage of good units produced out of total units — one of the three components of Overall Equipment Effectiveness (OEE).
How the calculation works
Quality rate = (Good units produced ÷ Total units produced) × 100.
Example
960 good units out of 1,000 total: (960÷1,000)×100 = 96%.

Pro Tips for Quality Rate
- Quality rate is one of three OEE components (with availability and performance) — track all three together for a complete efficiency picture.
- A declining quality rate trend often points to a specific process, material, or equipment issue worth investigating promptly.
Common Quality Rate Mistakes to Avoid
- Treating quality rate as a complete efficiency metric on its own, when it's only one of three components that together make up full OEE.
