Average Calculator

Enter numbers separated by commas, spaces, or new lines to see mean, median, mode, and other stats.

Paste or type a list of numbers separated by commas, spaces, or new lines. The tool computes the arithmetic mean, median, mode (or notes when every value is unique), plus min, max, range, sum, and count. All work happens locally so your numbers stay on your device.

How to use

  1. Enter the numbers. Use commas, spaces, tabs, or line breaks between values.
  2. Watch the statistics update live below the input.
  3. Mode shows the most frequent value or values, or none when all are unique.
  4. Click Copy summary for a one line report, or Reset to clear the list.

Examples

  • Input 1, 2, 2, 3, 4 gives mean 2.4, median 2, mode 2, min 1, max 4, range 3, sum 12, count 5.
  • Input with all unique values like 10 20 30 shows mode as none (all unique).
  • Even count 1 3 5 7 yields median 4 (average of the two central numbers).

FAQs

How is the median calculated for an even number of values?
The two middle numbers after sorting are averaged. For the list 1, 3, 5, 7 the median is (3 plus 5) divided by 2, which equals 4.
When is there no mode?
When every value appears exactly once, the highest frequency is 1 and there is no repeated value. The tool reports mode as none in that case.
Does it handle negative numbers and decimals?
Yes. Negative values and decimals are accepted and included in every statistic. Only the count guard and finiteness checks can reject input.
How many numbers can I enter?
Up to 100,000 values are processed. Larger lists are rejected with a message so the page stays responsive.
Is my data sent anywhere?
No. The calculations run entirely in your browser. Nothing you paste leaves your device.
