How to Calculate an Average
The average — more precisely the arithmetic mean — is the total of all values divided by how many values there are. It gives a single number that represents the typical size of the values in the list.
- 14 + 8 + 15 + 16 + 23 + 42 = 108
- 2108 ÷ 6 = 18
Therefore: The average of these six numbers is 18.
Mean vs Median
The mean uses every value, so one very large or very small number can pull it up or down. The median is the middle value once the list is sorted, which makes it more resistant to outliers.
For the list 2, 3, 3, 4 and 100 the mean is 22.4, but the median is 3. When a few extreme values are present, looking at both gives a better picture.

Frequently Asked Questions
Add all the values together, then divide the total by the number of values. For 10, 20 and 30 the average is 60 ÷ 3 = 20.
Yes. Values copied from a spreadsheet column arrive on separate lines, which the calculator reads correctly. Commas, spaces and semicolons also work as separators.
Yes. Enter negative values with a minus sign, such as −4.5, and decimals with a period.
In everyday use “average” means the arithmetic mean. Median and mode are other kinds of average, which is why this tool also shows the median.
