Many garment factories average 50–65%; well-run lines on long runs achieve 70–80%.
Produced minutes = Output × SMV
How it works
Line Efficiency Calculator
How productive was the line today? Compare produced minutes with available minutes.
Efficiency is the share of paid minutes that turned into standard minutes of output.
Formula
The formula, in full
- Produced minutes
- Output × SMV
- Available minutes
- Operators × Hours × 60
- Efficiency
- Produced ÷ Available × 100
Example
Daily line report
- 01Produced = 12,320 min
- 02Available = 19,200 min
- 03Efficiency = 64.17%
