Production Yield
Production yield is the proportion of input or total produced quantity that becomes acceptable output without being lost as scrap or rejected material.
What this term means in maintenance
Production yield is the proportion of input or total produced quantity that becomes acceptable output without being lost as scrap or rejected material.
Common calculation
Yield = Acceptable output ÷ Total input or total produced × 100
The selected basis should be stated.
Practical example
A process produces 1,000 units and 940 are accepted.
Yield = 94%
Yield losses
Losses may result from:
- Scrap
- Process defects
- Startup loss
- Material loss
- Equipment settings
- Calibration error
- Wear
- Contamination
Maintenance connection
Equipment condition and measurement accuracy can materially affect yield.
Common mistake
Using different input and output boundaries between periods makes yield trends unreliable.

Quality Rate
Quality rate is the OEE component measuring the proportion of total production that meets the defined good-output requirement.
Scrap Rate
Scrap rate is the percentage of produced material or units that cannot be accepted or economically reworked.
Production Rework Rate
Production rework rate is the percentage of output requiring additional processing or correction before it can meet acceptance requirements.
Production Yield FAQs
- What is production yield?
The proportion of input or produced quantity becoming acceptable output.
- What reduces yield?
Scrap, defects, startup loss, settings, calibration, wear, contamination, and process variation.
- Why must the calculation boundary be defined?
Input and output definitions materially affect the result.
