How does the Average Calculator work?

The average (arithmetic mean) is the sum of all the values divided by how many values there are.

Average Calculator formula

mean = (x₁ + x₂ + … + xₙ) ÷ n

Example

The average of 12, 18, 25, 30 and 45 is 130 ÷ 5 = 26.

Frequently asked questions

Should I use the mean or the median?

The median (middle value) is better when a few very large or small values would distort the mean — for example house prices or incomes.
