Continuous Improvement & Quality Analysis

Rolled Throughput Yield Calculator

Calculate rolled throughput yield across sequential process steps and estimate expected good output from a starting quantity.

Required Data Structure

Use one row per sequential process step. Yield may be entered as either a percent or decimal.

Step column: process step name
Yield column: step yield, such as 98 or 0.98
Starting units are optional and are used to estimate expected good output

Step	Yield Percent
Receiving inspection	98
Machining	96
Deburr	97.5
