You can multiply the individual throughput yields at each process step to obtain the overall, rolled throughput yield. When you calculate throughput yield, you count only the units that make it through the process without rework or scrap. Using the example above, YRT = YTP at step 1 * YTP at step 2 * YTP at step 3.
How is rolled throughput yield calculated?
- Rolled Throughput Yield = Yield 1 x Yield 2 x …. ...
- My processes are working at a nice 95% first pass yield rate, but my rolled throughput rate is just under 60%. ...
- My rolled throughput yield is 100%.
How do you calculate rolled first pass yield?
The total first time yield is equal to FTYofA * FTYofB * FTYofC * FTYofD or 0.9000 * 0.8889 * 0.9375 * 0.9333 = 0.7000. You can also get the total process yield for the entire process by simply dividing the number of good units produced by the number going into the start of the process.
