A pie chart shows how a total is split into parts. This pie chart maker turns a list of labels and values into a clean pie or donut chart, with the percent and angle of every slice. Students use it for statistics homework and science projects. Adults use it to show budgets, survey results and market share.
Type one item per line, like Rent, 1200. The chart updates as you type, and you can download it as an image.
How to use it
- Type one item per line as a label, a comma and a number.
- Add a title and choose pie or donut, and whether slices show percent, value or nothing.
- Read the chart and the table of percents and angles, or download the image.
How a pie chart is calculated
Each slice is its value divided by the total. Percent = value ÷ total × 100, and angle = value ÷ total × 360°. All the angles add up to 360° and all the percents to 100%.
Example
A budget has Rent 1,200, Food 450, Transport 220, Savings 300 and Fun 180, a total of 2,350. Rent is 1,200 ÷ 2,350 = 51.1%, which is an angle of 184°.
When to use a pie chart
Pie charts work best for a few parts of one whole. With many slices or values that are close together, a bar graph is easier to read.

What angle does a 25% slice have?
Correct answer: 90°. 25% of 360° = 90°.
The slices of a pie chart always add up to

Enter one label and value per line, like Rent, 1200. The chart is drawn for you.
How do I find the angle of a slice?
Divide the value by the total and multiply by 360 degrees.
Can the values be percents?
Yes. Any numbers work. Percents like 40, 35 and 25 make slices of 40%, 35% and 25%.
Can I download the chart?
Yes. Use Download image (SVG), which works in documents and slides.
Can values be negative?
