How to calculate defects per million opportunities
Defects Per Million Opportunities (DPMO) is a standard quality metric, especially in Six Sigma methodology, that normalizes defect counts to a common million-opportunity scale.
How the calculation works
DPMO = (Defects found ÷ Total opportunities) × 1,000,000.
Example
12 defects out of 8,000 opportunities: (12÷8,000)×1,000,000 = 1,500 DPMO.

Pro Tips for Defects Per Million Opportunities
- DPMO allows comparison across processes with very different opportunity counts, unlike a raw defect count or percentage alone.
- This metric underlies Six Sigma quality levels — a 'six sigma' process corresponds to roughly 3.4 DPMO, an extremely low defect rate.
Common Defects Per Million Opportunities Mistakes to Avoid
- Comparing raw defect counts between processes with very different opportunity counts, instead of normalizing to DPMO for a fair comparison.
