Average Calculator
Find the mean, median, mode, sum, range, min and max of any list of numbers instantly.
Calculate the average and more
The Average Calculator finds the mean, median, mode, sum, count, range, minimum, and maximum of any list of numbers — all at once. Paste your data separated by commas, spaces, or new lines, and every statistic updates instantly. It is the fast way to summarize a dataset without a spreadsheet.
Mean, median, and mode explained
These three "averages" each describe the center of your data differently. The mean is the sum divided by the count — the everyday average. The median is the middle value when the numbers are sorted, which resists being skewed by extreme outliers. The mode is the value that appears most often. Looking at all three gives a fuller picture than any one alone.
Which average should you use?
| Measure | Best when |
|---|---|
| Mean | Data is fairly symmetric with no big outliers |
| Median | Data is skewed or has outliers (e.g. incomes) |
| Mode | You need the most common value or categories |
How to use it
- Enter or paste your numbers, separated by commas, spaces, or line breaks.
- Read the mean, median, mode, and the rest of the statistics instantly.
- Add or remove values and the results recalculate immediately.
What each statistic tells you
- Sum — the total of all values.
- Count — how many numbers you entered.
- Range — the spread between the smallest and largest values.
- Min / Max — the extremes of your data.
Common uses
Averages are everywhere: a student averaging test scores, a manager summarizing sales, a scientist reporting measurements, or anyone making sense of a column of numbers. Because this tool also shows median and mode, it is especially useful when your data has outliers that would distort a plain mean — incomes, prices, and response times are classic examples.

Frequently asked questions
What is the difference between mean and average?
They are the same thing in everyday use — the sum of the values divided by how many there are.
When should I use the median instead of the mean?
Use the median when your data has outliers or is skewed, because it is not pulled toward extreme values.
What is the mode?
The mode is the value that appears most frequently. A dataset can have one mode, several, or none.
How do I enter my numbers?
Separate them with commas, spaces, or new lines. The calculator parses them automatically.
