Production Yield Calculator
Production yield measures the percentage of units produced that meet a chosen quality definition.
How to use this calculator
- Enter total produced and good units. The calculator returns yield and rejected-unit rate.
- Check the labels and units before using a result outside this page.
- Change one input at a time if you want to compare scenarios.
Formula and method
Yield = good units ÷ total units produced × 100%
- Yield = good units ÷ total units produced × 100%
- Define treatment of rework, test failures and scrap consistently across periods.
Worked examples
Worked example
940 acceptable units from 1,000 produced.
Yield is 94%; 60 units, or 6%, are rejected or not counted as good.
