Average Calculator

How to use Average Calculator

Paste numbers separated by commas, spaces, semicolons or line breaks. The arithmetic mean is the sum divided by the number of values.

How Average Calculator calculates the result

Add all input values, then divide by the number of values. A single unusually large value can raise the mean substantially; consider the median for skewed data.

Example

For 10, 20 and 30, the average is 20, the minimum is 10 and the maximum is 30.

What to know

This is the unweighted arithmetic mean; it is not a median. For very large lists, the browser and floating-point precision can limit accuracy.
