Free Pareto Chart Maker — Paste Data, Download Instantly
A Pareto chart answers one question: which few causes drive most of the effect? Bars are sorted largest to smallest, and the line tracks the cumulative percentage — where it crosses 80%, you have your vital few.
| Month | Product A | Product B |
|---|---|---|
Bars sorted descending; the line shows the cumulative percentage (80/20 rule).

Frequently asked questions
Do I need to sort my data before pasting?
No — the chart sorts the bars descending automatically and computes the cumulative percentage line for you.
What is the 80/20 rule in a Pareto chart?
In most datasets a small number of categories accounts for about 80% of the total. The cumulative line shows exactly where that threshold falls so you can prioritize.
