In Excel: select your labels and values, then Insert ▸ Chart ▸ Pie. To show each slice as a percentage, the share of a value is =value/SUM(range).
What this does
A pie chart shows how parts make up a whole, with each slice sized by its share of the total. It works best with a handful of categories that add to a meaningful 100% — market share, budget split, survey responses. Beyond five or six slices it gets hard to read, where a bar chart usually communicates better. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. Treat “doing a pie chart in excel” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected chart shows up while it is still harmless. 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. That turns a visual that makes the number obvious at a glance into a method you can reuse, explain, and defend when the workbook leaves your screen.
A worked example
With quarters Q1–Q4 valued 30, 45, 15, 60 (total 150), each slice is value/total: Q4 is 60/150 = 40% of the pie. In a cell, =B2/SUM($B$2:$B$5) gives that share; format it as a percentage and add data labels so the slices are annotated. The donut above recomputes every slice as you edit the values. A pie chart is the fastest way to make a composition obvious — where the money goes, who holds what share. Used on the right data (a few parts of one whole) it is instantly readable to any audience. 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
Everything above works in Google Sheets too. Excel and Sheets share the formula syntax used here; only the surrounding menus are arranged differently. That portability is deliberate — learn it once and it follows you between the two tools and across Windows and Mac. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. Here is the takeaway for “doing a pie chart in excel”: copy the answer if you are busy, but if you have a spare few minutes, rebuild the example in Excel yourself with the tool above open beside it. That single pass — type it, run it, watch the result move when you change an input — is what turns a formula you found into a technique you trust. Keep your inputs labelled and referenced, never hard-coded, and the same sheet stays correct and auditable as it grows. Done that way, you will not need to look this up again, and you will be the person others ask.
Common mistakes
- Using a pie for more than ~6 categories, where slices blur together — switch to a bar chart.
- Plotting values that do not sum to a meaningful whole, so percentages mislead.
- Including a total row in the data, which adds a giant 50% slice.
- Relying on colour alone; add labels so the chart is readable in greyscale.
Frequently asked questions
How do I show percentages on each slice?
Add data labels, then in label options tick “Percentage”. Excel computes each slice’s share of the total automatically.
Pie or bar chart?
Pie suits a few parts of one whole; bar charts compare many categories or values that do not sum to 100%. When in doubt, use a bar chart — it is easier to read.
Why does my pie look wrong?
Usually a stray total row or a blank category is included. Plot only the category/value pairs that add to your whole.
