Use this DPMO calculator to find out the popular measure of process performance - defects per million opportunities.

We calculate two values: the distance from the mean to the Upper Limit, and from the mean to the Lower Limit. The "min" function means we only report the worst side.

Dec 8, 2025 · To calculate the defects per million opportunities, multiply the number of defects by 1 million, then divide by the product of the number of units times the number of opportunities …

5 days ago · To calculate DPMO, you can use the formula: DPMO = [total number of defects in sample / (sample size units x number of defect opportunities per unit in the sample)] x …

Use this sigma calculator to easily calculate process sigma level, defects per million opportunities (DPMO, PPM), yield, rolled throughput yield (RTY), percent defects, percent defect units, as …

Use this Six Sigma Calculator to calculate the DPMO, DPO, DPU, Sigma Level and the process Yield, based on the number of units, number of defect opportunities per unit, and the number …

To accurately calculate DPMO, you need the number of defects (D), the number of units tested or produced (U), and the number of opportunities for a defect per unit (O). These three …

DPMO is considered long-term measurement of a process and this can be directly converted into a long-term z-statistic (sigma value) DPMO = DPO * 1,000,000. DPO = Defects per …

Apr 10, 2025 · How to Calculate DPMO / DPMO Formula To calculate DPMO: DPMO = DPU × 1, 000, 000 Opportunities Where DPU (defects per unit) is: DPU = Defective Units Total Number …
