Apply the 80/20 rule to identify the vital few causes that drive most effects. Prioritize your improvement efforts where they matter most.
All calculations are processed locally. Your data never leaves your browser.
Pareto Charts embody the 80/20 rule: approximately 80% of effects come from 20% of causes. Identify the "vital few" issues that will have the greatest impact when solved.
The cumulative line shows how quickly issues accumulate. See exactly how many categories you need to address to reach 80% improvement—or any threshold you choose.
Focus limited resources where they'll have the biggest impact. Pareto Charts help teams avoid spreading effort across trivial many while ignoring vital few.
Create Pareto Charts to apply the 80/20 principle. Named after Vilfredo Pareto and popularized by Joseph Juran, identify the vital few causes that drive most effects. Prioritize quality improvements with our free online tool.
Named after economist Vilfredo Pareto, this principle was popularized in quality by Joseph Juran. Pareto observed that 80% of Italy's wealth was owned by 20% of the population—a pattern repeated across many domains.
In quality management, this translates to: 80% of defects come from 20% of causes, 80% of customer complaints come from 20% of issues. Finding and fixing the vital few delivers maximum improvement.
Bars are sorted from tallest to shortest, left to right, showing each category's individual contribution. The cumulative line rises to show running total percentage. Where the line crosses 80% marks your vital few.
Categories to the left of the 80% threshold are your priority targets. Address these first for maximum impact before moving to the "trivial many" on the right.
Pareto Charts often follow Check Sheet data collection and precede root cause analysis with Fishbone Diagrams. After identifying what to fix, use Control Charts to verify improvements are maintained.
