How to Do a Pareto Chart in Excel

What this does

A Pareto chart is a sorted bar chart with a cumulative percentage line drawn over it on a secondary axis. It answers one question: how few categories account for most of the total. Since Excel 2016 it is a native statistic chart, so the sorting, the running total and the second axis are all handled by the chart type rather than by helper columns. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “do a pareto chart in excel”. Start on a copy or a tiny sample, keep the affected chart visible, and compare the result with the tool above before you touch the real workbook. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. The point is a visual that makes the number obvious at a glance, but the practical win is that someone else can open the file and understand what happened without asking you.

A worked example

Six defect types with counts 142, 96, 41, 22, 12 and 7 — 320 failures in total. Insert ▸ Insert Statistic Chart ▸ Pareto. The bars reorder themselves largest first and the cumulative line reaches 74% at the second bar (238 of 320), so two of the six defect types account for roughly three quarters of all failures. Prioritisation arguments are won with the cumulative line: it converts a list of complaints into a defensible claim about where two fixes remove most of the pain. One habit worth forming early: name the cells that hold your inputs, so the formula reads in plain language instead of a string of cell addresses. A reviewer — or you in three months — can then follow the logic without decoding what B7 and D2 were supposed to mean, which is most of what makes a sheet maintainable.

In Google Sheets

If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. Nothing on this page is behind a login: the tool runs entirely in your browser, the formula is shown in full with one-click copy, and the steps work the same on Windows and Mac. That is the whole promise here — the exact answer, a way to prove it on your own numbers, and just enough context to make it stick. If you take one thing from this page on “do a pareto chart in excel”, make it the habit rather than the keystrokes: set the problem up with labelled inputs, reference those cells, and let Excel do the recomputing. Bookmark the page for the syntax, but do the example once in a blank sheet and check it against the tool above — five minutes of hands-on practice fixes the method in memory far better than re-reading, and it surfaces the small snags while they are still harmless. After that the technique is genuinely yours: faster than searching for it again, and reliable enough to drop into work that other people depend on.

Common mistakes

• Feeding it percentages instead of counts, which makes the cumulative line meaningless.
• Charting thirty categories, where the tail is unreadable and an Overflow bin would tell the same story.
• Comparing counts of things with different costs — twenty cheap defects can outrank one expensive one and hide the real problem.
• Building it manually in Excel 2013 or earlier and forgetting to sort descending, which breaks the cumulative reading entirely.
