What the result means
The average is the arithmetic center of the values you entered and treats every value with equal weight. Use the minimum and maximum alongside it to see whether the mean is being pulled by a low or high value, especially for small lists.
Use the result this way
- Start with Average, then use supporting outputs for context.
- Verify Values before copying the result.
- Check the formula, example, and assumptions before reusing the answer.

How to use this calculator
Use Average Calculator when you need average, then use sum and count to check the context for data review, classwork, quality checks, and quick descriptive summaries.
Best for
- Summarizing a list of values
- Checking spread, center, or sample assumptions
- Reviewing a default example before entering your own values.
Check before relying
- Confirm whether the data is a sample or population and whether outliers should stay in the list.
- All entered values have equal weight.
- The calculator uses arithmetic mean, not median or mode.

Formula
Average = sum of values / count of values. The calculator also reports count, sum, minimum, and maximum so you can check whether the mean is being shaped by the data range.

Inputs
Enter values separated by commas, spaces, or line breaks. Each value is weighted equally.
Example
Values 12, 15, 18, 21, and 24 have a sum of 90 and a count of 5. The average is 90 / 5 = 18.
FAQ
How do I calculate average?
Add all values and divide by how many values there are. For example, five values with a total of 90 have an average of 18.
Is average the same as mean?
In this calculator, average means arithmetic mean: all entered values are added together, then divided by the count.
Can I paste values from a spreadsheet?
Yes. You can paste values separated by commas, spaces, or line breaks, including a copied spreadsheet column.
Does each value have the same weight?
Yes. This calculator uses an unweighted arithmetic mean, so every entered value contributes equally to the result.
What should I verify before using average calculator?
Verify values, the displayed formula, and the worked example before copying the result into another document or decision.
What is the main output of average calculator?
Average is the first value to read. Use the supporting outputs and assumptions to understand why it changed.
