Frequently asked questions
What does this average calculator do?

How do I use this average calculator?
Enter each value in the list.
What does the result mean?
The mean is the total divided by the count.
What should I check before relying on it?
Outliers can make an average misleading.
What's the difference between the average and the median shown here?
The average, or mean, is the sum divided by the count, so it's pulled toward unusually large or small values. The median is the middle value when sorted, which stays more stable when a few numbers are far from the rest.
How many numbers can I enter?
Enter as many comma-separated values as you need — there's no fixed limit, so it works equally well for a handful of numbers or a longer list.
