This free online average calculator instantly finds the mean, median, mode, sum, minimum, and maximum of any list of numbers. Simply paste or type your values separated by commas, spaces, or new lines to get a complete statistical summary in one click.
How to Use the Average Calculator
Type or paste your list of numbers into the "Enter Numbers" box, separated by commas, spaces, or new lines.
Click "Calculate" to process the list.
Review the results table for the count, sum, mean, median, mode, minimum, and maximum.
How Each Value Is Worked Out
Mean (Average): the sum of all values divided by how many values there are.
Median: the middle value once the list is sorted. With an even count, it is the average of the two middle values.
Mode: the value that appears most often. If several values tie for the highest count, all of them are listed. If every value appears only once, the tool reports "No mode".
Minimum and maximum: the smallest and largest values. Subtract one from the other to get the range, a quick measure of spread.
The sum, mean and median are rounded to four decimal places. Duplicates are kept, so a value entered twice counts twice.
Worked Example: When Mean and Median Disagree
Say a small shop records daily sales (in thousands of rupees) for a week: 12, 15, 15, 18, 22, 25, 95. The last day had an unusually large bulk order.

One extreme day pulls the mean up by about 11, while the median moves by only 1.5. The mean of 28.86 describes no typical day, because six of the seven days were below it. When data has a few very large or very small values, as salaries, house prices and order values often do, the median is the better summary of a typical value.
Things to Watch For
Commas are treated as separators, so do not type thousands separators. Enter 125000, not 1,25,000, otherwise the tool reads it as three numbers: 1, 25 and 0.
This is a simple (unweighted) average. If items carry different weights, such as subjects with different credits, multiply each value by its weight, add those products, and divide by the total weight. Marks of 78, 85 and 62 with weights 4, 3 and 2 give a weighted average of 76.78, not the simple average of 75.
Do not average percentages or rates taken from groups of different sizes. Go back to the underlying totals instead.
Words, units and symbols such as ₹ or % attached to a number make that entry invalid, and it is silently skipped. Check that the Count matches the number of values you meant to enter.
Frequently Asked Questions
Along with the average (mean), it also reports the count, sum, median, mode, minimum, and maximum of the numbers you enter, all from a single list.
The numbers are sorted from smallest to largest, and if there is an even count the median is the average of the two middle values; for an odd count it is simply the middle value.
Use the mean when values are fairly evenly spread and you need a figure that reflects every value, such as average marks across tests. Use the median when a few extreme values could distort the picture, such as incomes or property prices, because the median is not pulled by outliers.
If two or more values share the highest frequency, all of them are modes and the tool lists them in ascending order. If no value appears more than once, there is no mode, and the tool says so.
Yes. Values such as -4.5 or 0.25 are read normally. Use a dot for decimals; a comma is treated as a separator between numbers, so 2,5 is read as two separate values, 2 and 5.
