How to calculate scrap rate
Scrap rate measures the percentage of produced units that get scrapped rather than sold or used — a manufacturing quality and cost metric.
How the calculation works
Scrap rate = (Scrapped units ÷ Total units produced) × 100.
Example
40 scrapped units out of 1,000 total: (40÷1,000)×100 = 4%.
