Calculation

(10 + 20 + 30 + 40 + 50) ÷ 5 = 30

How it works

  1. 1

    Enter numbers

    Paste a list of numbers, separated by line breaks, semicolons, or commas.

  2. 2

    Review the metrics

    Review the mean, median, mode, minimum, maximum, range, and sum at once.

  3. 3

    Copy the result

    Copy the mean, the sorted values, or all metrics together.

Good to know

The average calculator computes the mean, median, mode, minimum, maximum, range, sum, and the count of values, duplicates, and unique values from an entered list of numbers directly in your browser, all at once. The list can be entered via line breaks, semicolons, tabs, or a comma-separated list.

Calculation runs locally in the browser. Ambiguous or invalid values are not guessed; for outliers, also check the median and range, since they can shift the mean significantly.

Typical use cases

Get multiple metrics from a data list at once

Paste a list of measurements or grades to see the mean, median, mode, and range at once, without separate calculations.

Spot duplicates and outliers in a list

Use the display of duplicates and unique values to quickly check whether a data list contains recurring values or outliers.

Tips for better results

Also check the median with outliers

A single extremely high or low value can shift the mean significantly — the median is often more informative in such cases.

Use the input format flexibly

Values can be pasted via line breaks, semicolons, tabs, or as a comma list — convenient when copying from spreadsheets.

Features

  • Eight metrics at a glance

    Mean, median, mode, minimum, maximum, range, sum, and count are calculated simultaneously.

  • Flexible list input

    Line breaks, semicolons, tabs, and comma lists are all recognized equally.

  • Local calculation

    Calculation happens directly in the browser, without transmission to a server.
