Average Calculator

Whether you are totting up test scores, monthly bills or match results, this average calculator gives you the mean, median, mode and range of any list of numbers in one go. Paste your figures, and the tool sorts them, adds them up and shows the working, so you can see exactly how the arithmetic mean is found and check it against your own sums. It accepts whole numbers, decimals and negative values.

Quick answer: An average calculator finds the mean by dividing the sum of values by the number of values. For 72, 85, 85, 90, 64, 78 and 91, the sum is 565 across 7 values, so the mean is 80.71, while the median and mode are both 85 and the range is 27.

What Is an Average?

An average is a single number that represents a whole set of values. In everyday use it usually means the mean, but there are three common types. The mean is the total divided by how many numbers there are. The median is the middle value once the list is sorted. The mode is the value that appears most often.

The formula for the mean is mean = sum of values ÷ number of values. For the scores 72, 85, 85, 90, 64, 78 and 91, the sum is 565 and there are 7 values, so the mean is 565 ÷ 7 = 80.71. Sorted, the middle value is 85, which is the median, and 85 also appears twice, so it is the mode. The range is the highest minus the lowest: 91 minus 64 is 27.

How Do You Use the Average Calculator?

Step 1: Enter Your Numbers

Type or paste your numbers into the box, separated by commas, spaces or new lines, so a column copied from a spreadsheet works fine. Type or paste your numbers into the box. You can separate them with commas, spaces or new lines, so a column copied from a spreadsheet works fine. Leave out thousands separators, because a comma is treated as a gap between two numbers.

Step 2: Choose the Decimal Places

Pick how many decimal places you want in the results. Two is right for most purposes, including money. If you need to express a decimal answer as a share of something, the fraction to decimal calculator helps you move between fractions, decimals and percentages without any guesswork.

Step 3: Read the Mean, Median and Mode

The mean appears in large type, with the median, mode, range and sum below it. If no number repeats, the mode shows as None. If several values tie for most common, each one is listed.

Step 4: Check the Working

The working box shows the sum divided by the count and the full sorted list, so you can follow every step. To see how much one average has moved since last month, the percentage increase calculator compares the two figures and shows the change as a percentage.

Mean, Median or Mode: Which Should You Use?

Average	How it works	Best for
Mean	Sum ÷ count	Even data without extreme values, such as test scores
Median	Middle value when sorted	Data with outliers, such as house prices or salaries
Mode	Most common value	Categories or repeated values, such as shoe sizes
Range	Highest minus lowest	Showing how spread out the data is

A few very large values can pull the mean upwards, which is why official statistics on pay and house prices often quote the median as the typical value instead of the mean. When the mean and median are far apart, your data is skewed and the median is usually the fairer figure to report.
