📊 Average Calculator

About this Average Calculator

This average calculator takes any list of numbers — marks, prices, measurements, daily sales — and works out the full picture: count, sum, mean, median and mode, plus the smallest and largest values. The median and mode are useful when a few very big or small numbers would distort the simple average.

How to use it

1. Type or paste your numbers into the box, separated by spaces, commas or new lines.
2. Click Calculate average.
3. Read the count, sum, mean, median, mode, minimum and maximum.

Example

For the marks 10, 25, 30, 42 and 25, the mean is 26.4, the median is 25, the mode is 25 and the sum is 132.

Frequently asked questions

What is the difference between mean and median?

The mean adds everything and divides by the count. The median is the middle value when the numbers are sorted, so it is not pulled around by extreme values.

What if no number repeats?

Then there is no mode, and the tool says so — every value appears the same number of times.
