Pareto Analysis by the Numbers
How to Make an 80/20 Rule Chart
From raw data to actionable Pareto analysis in minutes
Enter Your Categories and Counts
Add each category and its frequency or impact value in the data table. Type them in, paste from a spreadsheet, or ask AI to generate the chart from a plain-language description.
e.g. Wrong order: 45, Billing error: 38, Long wait: 31, Poor communication: 18, Packaging damage: 9, Delayed delivery: 7
Chart Builds Itself Instantly
MakeCharts sorts bars from highest to lowest, draws the cumulative percentage line, and places the 80% reference line - all automatically and without any configuration.
Bars rank from largest defect category down, cumulative line crosses 80% after the third bar
Identify the Vital Few
Read off which categories fall to the left of the 80% line - these are your top priorities. Everything to the right is the trivial many you can address later.
e.g. 3 out of 6 defect types cause 80% of all customer complaints - focus resources there first
Export and Share
Download your Pareto chart as PNG or SVG, copy a shareable link, or embed it in a report, dashboard, or slide deck.
Paste into a PowerPoint slide or share the link directly in Slack for a team review

Frequently Asked Questions
What is a Pareto chart?
A Pareto chart is a combination bar and line chart where categories are ranked from highest to lowest frequency or impact, with a cumulative percentage line overlaid on a secondary axis. It is based on the Pareto principle - commonly called the 80/20 rule - which observes that roughly 80% of effects come from 20% of causes. It is a core tool in quality management, Six Sigma, and root-cause analysis.
What is the 80/20 rule in a chart?
The 80/20 rule in a chart refers to the visual boundary where the cumulative percentage line crosses the 80% mark. Categories to the left of that line are the 'vital few' - the small number of causes responsible for the majority of outcomes. Our 80/20 rule chart maker draws this reference line automatically so you can read the threshold at a glance without any manual calculation.
How do I make an 80/20 rule chart?
Enter your categories and their frequency or impact values into the data table, then MakeCharts sorts the bars automatically, overlays the cumulative percentage line, and adds the 80% reference marker. You can also describe your data in plain language to the AI and it will generate the Pareto chart for you. The whole process takes under two minutes.
Is this Pareto chart maker free?
Yes. The core 80/20 rule chart maker is free with no signup required. You can create, customize, and download Pareto charts at no cost. Free AI credits are included so you can also try AI-powered chart generation. Paid plans unlock more AI usage, file upload, and embed codes.
Can I use this for Six Sigma or quality control analysis?
Absolutely. Pareto charts are a standard tool in Six Sigma, Lean, ISO quality frameworks, and DMAIC root-cause analysis. Our chart maker produces correctly formatted Pareto diagrams with sorted bars, a cumulative line, and an 80% reference line - everything required for a quality improvement report or a DMAIC presentation.
