Product Yield Formula
Variables:
- PY is the Product Yield (%)
- GP is the good first-pass products for first-pass yield; use final good products, including successfully reworked units, for final yield
- TP is the number of units started in the same tracked cohort
Divide the corresponding good-unit count by units started in the same cohort, then multiply by100. First-pass yield excludes rework; final yield includes only additional units successfully recovered. The remaining reject pool is not necessarily final scrap. The optional cost calculation assumes every unrecovered unit is scrapped and excludes rework costs. Rolled throughput yield multiplies conditional first-pass stage yields for the same process route, not unrelated marginal percentages.
How to Calculate Product Yield?
The following steps outline how to calculate the Product Yield.
- First, count good first-pass products, or clearly choose a final-good count that includes successful rework.
- Next, count units started in the same cohort and time window.
- Next, gather the formula from above: PY = GP / TP * 100.
- Finally, calculate the Product Yield.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total good products made = 50
total of good and bad products made = 70
Yield = 50 / 70 ×100 ≈71.428571%. For input planning, ceiling(target good / yield fraction) gives an expected-output plan at the stated yield, not a guaranteed good-unit count. Actual batch yield can vary.
Frequently Asked Questions
What is Product Yield?
Product Yield refers to the percentage of good (or acceptable) products out of the total products manufactured, including both good and bad items. It's a key performance indicator in manufacturing that measures the efficiency and quality of production.
Why is Product Yield important?
Product Yield is crucial for manufacturers because it directly impacts profitability and operational efficiency. High yield rates indicate efficient use of materials and resources, reducing waste and production costs, while ensuring a higher output of marketable products.
How can manufacturers improve Product Yield?
Manufacturers can improve Product Yield by optimizing production processes, investing in quality control systems, training employees, maintaining equipment properly, and using high-quality materials. Continuous improvement practices like Lean and Six Sigma can also contribute to higher yields.
What is the difference between First Pass Yield and Overall Yield?
First Pass Yield measures the percentage of products that meet quality standards without requiring rework or repair right after the first manufacturing process. Overall Yield, or Product Yield, considers all products that eventually meet quality standards after any necessary reworks or repairs throughout the entire production process.
