Average Calculator
Find the mean, median, sum, min, max, and range of a list of numbers.
Enter or paste a list of numbers — separated by commas, spaces, or new lines — to get the average (mean) along with the median, sum, count, minimum, maximum, and range. Results update as you type.
It is the fast way to summarise a set of values without a spreadsheet, whether that is test scores, prices, or measurements.

Formula
Mean (average)
sum of values ÷ count = mean
Add every number, then divide by how many there are. Example: (2 + 4 + 9) ÷ 3 = 5.
Median
the middle value when sorted
Sort the numbers; the median is the middle one (or the average of the two middle ones for an even count).

Mean vs. median — which average?
The mean adds all the values and divides by the count; it is the everyday “average”. The median is the middle value when the numbers are sorted. The mean is sensitive to outliers — one very large or very small value pulls it up or down — while the median is more robust. For skewed data like incomes or house prices, the median often describes the typical value better.
The other statistics
Sum and count tell you the total and how many values there are. Min and max are the smallest and largest values, and the range is the difference between them — a quick measure of how spread out the numbers are.
Frequently asked questions
How do I calculate the average of numbers?
Add all the numbers together, then divide by how many numbers there are. The average (mean) of 2, 4, and 9 is (2 + 4 + 9) ÷ 3 = 5.
What is the difference between mean and median?
The mean is the sum divided by the count; the median is the middle value when sorted. The median is less affected by outliers.
How should I separate my numbers?
Use commas, spaces, or new lines — any mix works. Non-numeric text is ignored.
Is my data private?
Yes. The list is processed in your browser and never uploaded.
