Quality calculator
Rolled Throughput Yield Calculator
See how individual operation yields combine into the true end-to-end first-pass yield of a process route.
What this calculator does
- Calculate total process yield by multiplying yield across sequential operations.
- Use when a product passes through multiple steps and small losses compound into a larger final yield loss.
- Calculate total process yield by multiplying yield across sequential operations.
Formula used
- RTY = step 1 yield × step 2 yield × step 3 yield × step 4 yield
- Final good units = input units × RTY
- Total loss = input units − final good units
Inputs explained
- Step 1 yield: undefined
- Step 2 yield: undefined
- Step 3 yield: undefined
- Step 4 yield: undefined
- Input units: undefined
How to use the result
- Use when a product passes through multiple steps and small losses compound into a larger final yield loss.
- This is a planning calculator. Validate assumptions against your process data before using the result as a final quote, schedule, or engineering decision.
Common questions
- Which inputs usually drive the rolled throughput yield result? step 1 yield, step 2 yield, step 3 yield, step 4 yield, and input units usually have the biggest effect. When one of those assumptions changes, rerun the calculator and compare the new % result before updating the plan.
- What does the rolled throughput yield calculator do? Calculate total process yield by multiplying yield across sequential operations.
- What inputs do I need for the rolled throughput yield calculator? You need step 1 yield, step 2 yield, step 3 yield, step 4 yield, and input units. Use measured values from your line, quote package, supplier data, or current production plan whenever possible.
- How should I interpret the rolled throughput yield result? Treat the % output as a planning estimate for quality work. Compare it against process history, quoted assumptions, and operating limits before making final decisions.
