Enter the total opportunities and defects to calculate your Six Sigma metrics.

Six Sigma Calculation Formula

The following formula is used to calculate the defects per million opportunities (DPMO) and sigma level.

DPMO = (Defects / Total Opportunities) * 1,000,000
Sigma Level = 1 - (DPMO / 1,000,000)

Variables:

  • DPMO is the number of defects per million opportunities.
  • Total Opportunities is the total number of chances for a defect to occur.
  • Defects are the total number of defects found.

To calculate the DPMO, divide the number of defects by the total opportunities and multiply by one million. The sigma level is calculated by subtracting the DPMO divided by one million from one.

What is Six Sigma Calculation?

Six Sigma calculation refers to the process of determining the quality of processes by measuring the defects per million opportunities and calculating the sigma level. This methodology helps in identifying and eliminating defects in processes to achieve higher quality and efficiency.

How to Calculate DPMO and Sigma Level?

The following steps outline how to calculate the defects per million opportunities (DPMO) and sigma level using the given formula.

  1. First, determine the total number of opportunities for defects to occur.
  2. Next, count the total number of defects found.
  3. Use the formula from above: DPMO = (Defects / Total Opportunities) * 1,000,000.
