What is a Pareto Chart?
Pareto charts combine bar charts and line graphs to illustrate the Pareto principle (the 80/20 rule)—the idea that 80% of effects typically come from 20% of causes. The bars show individual values in descending order, while the cumulative percentage line shows how each value contributes to the total. Pareto charts help identify which factors have the most significant impact.
Pareto charts are essential for quality improvement and process optimization, helping teams focus on the vital few problems that account for the majority of issues. They're used in Six Sigma initiatives, customer complaint analysis, and failure mode analysis. By visualizing the cumulative contribution of each category, Pareto charts guide resource allocation to areas with maximum impact.

Pareto Chart Example: 500 Product Returns
An online store logged 500 product returns and tallied them by reason. The file has two columns, a reason and a count, in no particular order. That's all a Pareto chart needs: CleanChart sorts the bars largest first, adds the cumulative percentage line and draws the 80% reference line for you.
| Return reason | Returns | Share | Cumulative % |
|---|---|---|---|
| Wrong size | 168 | 33.6% | 33.6% |
| Damaged in transit | 121 | 24.2% | 57.8% |
| Not as described | 77 | 15.4% | 73.2% |
| Arrived late | 41 | 8.2% | 81.4% |
| Changed mind | 35 | 7.0% | 88.4% |
| Defective part | 27 | 5.4% | 93.8% |
| Wrong item shipped | 19 | 3.8% | 97.6% |
| Missing accessories | 12 | 2.4% | 100.0% |
How to read it
- The red line crosses 80% at the fourth bar. Four of the eight reasons (wrong size, damaged in transit, not as described, arrived late) cause 407 of the 500 returns, or 81.4%.
- That's a 50/81 split, not 80/20. The 80/20 rule is a rule of thumb, so read the chart at the point where the cumulative line crosses 80%, wherever that falls.
- The first two bars alone cover 57.8% of returns. Better size guidance and sturdier packaging are where a fix pays off first.
- The four reasons right of the cutoff add up to 93 returns (18.6%). They're worth tracking, but not worth fixing first.

- 3.Include a descriptive title that explains what the chart shows
- 4.Ensure data is accurate and up-to-date before creating your chart
- 5.Consider your audience when choosing complexity and detail level
