How the Average Calculator works
Add all the numbers together, then divide by how many numbers there are. That is the arithmetic mean, which is what people usually mean by “the average”.
The median is shown too. If the average and the median are far apart, a few unusually high or low values are pulling the average.
The formula
Worked example
Using the default values shown in the calculator:
| Numbers to average | 85, 92, 78, 90, 88 |
|---|
- 85 + 92 + 78 + 90 + 88 = 433.
- 433 ÷ 5 = 86.6.
Result:
| Average | 86.6000 |
|---|---|
| Sum | 433.0000 |
| How many numbers | 5 |
| Median, for comparison | 88.0000 |
Frequently asked questions
How do I average percentages?
If each percentage is based on the same total, average them directly. If the totals differ, use a weighted average, with each percentage weighted by its total.
Does a zero count in the average?
Yes. A zero is a real value and lowers the average. Leave a value out completely if it is missing rather than zero.
