Industrial Equipment, Machinery & Capital Goods calculator
Factory Acceptance Yield Calculator
Use this calculator to measure factory acceptance yield for industrial equipment. It helps quality, test, and production teams see whether machines are reaching FAT ready status with acceptable first-pass performance.
What this calculator does
- Calculate first-pass factory acceptance yield from machines passing FAT, machines presented for FAT, and target yield.
- Use it when tracking how often equipment passes factory acceptance without major rework or retest.
- The result shows first-pass FAT performance against the target.
Formula used
- Factory acceptance yield = machines passing FAT first pass ÷ machines presented for FAT × 100
- Factory acceptance yield gap to target = factory acceptance yield - target FAT first-pass yield
Inputs explained
- Machines passing FAT first pass: Count machines, skids, panels, or systems that pass required FAT checks without major rework or retest.
- Machines presented for FAT: Use the total machines or systems submitted to FAT during the same period.
- Target FAT first-pass yield: Enter the internal KPI, customer requirement, or launch target for factory acceptance yield.
How to use the result
- Use it to prioritize debug reduction, test procedure improvements, supplier quality, and build readiness work.
- It depends on consistent FAT criteria and whether minor punch list items are counted as passes.
Common questions
- What is the factory acceptance yield calculator for? It calculates the share of machines that pass factory acceptance on the first pass.
- What information should I enter? Use first-pass FAT passes, total machines presented for FAT, and target yield.
- What does the result tell me? The result helps decide whether build and test readiness are improving.
- When is the result only an estimate? It is only an estimate when FAT pass criteria, product mix, or retest rules change.
