Pareto Chart Generator for 80/20 analysis
Free Pareto chart generator. Paste categories and counts to draw the 80/20 bar-and-line chart, then download SVG.
Paste categories and counts — renders an exact 80/20 bar-and-line chart as SVG, free
Categories and counts
Paste a category column plus a count. The chart sorts largest first. This tool does not run ABC inventory analysis.
6 categories parsed
n=6 · total=106 · first 3 categories reach 80%. The 80/20 split is a visual cutoff — this page does not rank root causes for you.

What is a Pareto chart?
A Pareto chart ranks categories by count and overlays the cumulative percent. The tall bars on the left are the vital few; the long tail is the useful many. The name comes from Pareto’s 80/20 observation, later turned into a quality tool by Juran. This page draws that figure from counts you already have. It does not run root-cause analysis, ABC inventory ranking, or a statistical test.
How to read the bars and the 80% line
- Paste a category column plus a count, or upload CSV/TSV. The engine sorts largest first. Blue bars are the categories that first reach 80% of the total; gray bars are the remainder. The orange line is cumulative percent on the right axis. The dashed red line is the 80% cutoff — a visual aid, not a decision this page makes for you.
- A generic bar chart keeps your original order. A histogram bins a continuous variable. A waterfall shows signed increments. None of those is a Pareto chart.
Pareto chart versus a bar chart or histogram
Use this page when you want ranked frequencies plus a cumulative percent. Use the bar chart maker for grouped or stacked comparisons that should not be re-sorted. Use the histogram maker for a distribution of one numeric variable. Use the fishbone diagram when you already know the vital few and need causes, not counts.
