Average (Mean) Calculator
Paste any list of numbers — the mean, sum, median, and range appear with the working shown.
How the average is calculated
The mean is the everyday "average": add every number to get the sum, then divide by the count of numbers.
Mean = sum of values ÷ number of values
The median is the middle value once the numbers are sorted (or the average of the two middle values if there's an even count). It's handy when a few very high or low numbers would pull the mean in a misleading direction.
FAQ
How do you calculate the average of numbers?
Add all the numbers to get the sum, then divide by how many numbers there are. That's the mean.
What's the difference between mean and median?
The mean is the sum divided by the count. The median is the middle value when sorted, which is less affected by outliers.
What separators can I use?
Commas, spaces, tabs, or new lines all work — mix them freely. Anything that isn't a number is ignored.
