Yield and First-pass Yield
How much good output are you getting from input?
Calculates final yield and first-pass yield and shows the rework burden.

How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Units started | units | Units started in the period |
| Good units | units | Good units after any rework |
| Good first time (no rework) | units | Units good first time without rework |
Method and formulas
- Final yield = good ÷ started
- First-pass yield = good first time ÷ started
- Reworked units = good − good first time
Limitations
- Single step; multiply step yields for rolled throughput yield
Typical uses
- Quality reporting
- Spotting hidden rework
Who it is for
- Quality engineers
- Production supervisors
What you get
- Final yield and first-pass yield
- Lost and reworked units
- Data checks
Interpreting the result
- A gap between final and first-pass yield is hidden cost and capacity
