Find the average, sum, count, minimum and maximum of a list of numbers pasted in any common layout.

For 10, 20, 30 and 40 the sum is 100, the count is 4 and the average is 25. Adding a missed test recorded as 0 to scores of 72, 85 and 90 gives a sum of 247 and an average of 61.75.
Values may be separated by spaces, commas, semicolons or new lines. They are added together and divided by how many there are. The result also reports the sum, the count and the smallest and largest values, which makes a mistyped entry easy to spot. Every entry must be a valid number; anything else is rejected rather than skipped.
A comma is treated as a separator, not a decimal mark, so 12,5 is read as 12 and 5; write 12.5 instead. Zeros count as values and pull the average down, and every number carries equal weight, so this is a plain arithmetic mean rather than a weighted average.
Separate values with spaces, commas, semicolons or new lines, so a column copied from a spreadsheet works as it is. For 10, 20, 30 and 40 the sum is 100, the count is 4 and the mean is 25. The result also lists the minimum and maximum, which is a quick way to spot a value typed with an extra zero. Do not use a comma as a decimal separator: 12,5 is read as two numbers, 12 and 5, so write 12.5 instead.
Every value has equal weight, including zeros. Test scores of 72, 85 and 90 average about 82.33, but adding a missed test recorded as 0 drops the mean to 61.75. A single extreme value has a similar effect: 1, 2, 3 and 100 have a mean of 26.5, while the median is 2.5. When one number is far from the rest, compare the mean with the Median Calculator before describing a typical value.
Negative and decimal numbers are valid, so temperatures of −5, 0, 5 and 12.5 degrees average 3.125. This tool calculates a simple arithmetic mean only. If items carry different weights, such as course credits or quantities bought at different prices, multiply each value by its weight, add those products and divide by the total weight; entering the values once each would give every item the same importance. For grade point averages with credits, use the GPA Calculator.
| Input | Result |
|---|---|
10, 20, 30, 40 | 25 (Σ 100 · n 4) |
72, 85, 90, 0 | 61.75 (Σ 247 · n 4) |
-5, 0, 5, 12.5 | 3.125 (Σ 12.5 · n 4) |
1, 2, 3, 100 | 26.5 (Σ 106 · n 4) |
Not with this tool, which gives every value equal weight. Multiply each value by its weight, add those products and divide by the total weight. For course credits use the GPA Calculator, and for prices paid in different quantities multiply each price by its quantity first.
Compare both when one value sits far from the rest. The numbers 1, 2, 3 and 100 have an average of 26.5 but a median of 2.5, so the average describes none of them well. The Median Calculator returns the middle value, which is steadier when outliers are present.
Blank space between values is ignored, so a column copied from a spreadsheet works as it is. Negative and decimal values are valid: −5, 0, 5 and 12.5 have a sum of 12.5 and an average of 3.125. Text or symbols that are not numbers produce an error instead of being skipped.
