How to Use the Average Calculator

Paste or type in a list of numbers — commas or line breaks both work — and the average updates as the list changes.

average = (sum of all values) ÷ (count of values)

4, 8, and 12 average out to 8 — sum them, divide by how many there are. This Average Calculator handles that along with the sum and count themselves. The catch with any average: a single outlier drags it hard. Ten people's average income looks nothing like what nine of them actually earn if the tenth is a billionaire — mathematically correct, practically misleading. Median (the middle value) usually tells the more honest story once outliers are in the mix.

Worth distinguishing from a weighted average, which is a separate tool here: this one treats every number the same, no exceptions. If your values should count unevenly — different importance, different sample sizes — that's a different calculation.
