How to use the average calculator

  1. Type or paste your numbers into the field — one number per line, or separated by commas or spaces.
  2. The calculator automatically works out the average, sum and median as you type.

How average and median are calculated

The average (also called the arithmetic mean) is found by summing all the numbers and dividing by the count:

Average = Sum of all numbers ÷ Count of numbers

Median is the number that falls in the middle of the list when the numbers are sorted in ascending order. If the count is even, the median is the average of the two middle numbers. Median is useful because, unlike the average, it isn't heavily affected by extreme individual values (outliers).

Frequently asked questions

What's the difference between average and median?

The average takes into account the value of every number, while the median only looks at which number is in the middle. If your dataset has a few very high or low numbers, the average can be "skewed" more than the median.

Which separators can I use between the numbers?

You can use line breaks, commas, semicolons or spaces — the calculator interprets all of these as separators between numbers.
