About This Calculator
The arithmetic mean — commonly called the average — sums all values and divides by the count. Enter as many numbers as you need, separated by commas or spaces, and get the mean along with the sum, count, and range.
How It Works
Type your numbers separated by commas or spaces. The result updates as you type. The URL updates too, so you can share or bookmark your list.
The Formula
Mean = (x₁ + x₂ + … + xₙ) / n
- xᵢ
- each value in the list
- n
- number of values
Frequently Asked Questions
- Is this the same as the mean?
- Yes. The terms "average" and "arithmetic mean" both refer to the sum divided by the count. Other types of average (median, mode, geometric mean, weighted mean) are different calculations.
- Can I enter negative numbers?
- Yes. Negative numbers are valid inputs and will lower the mean accordingly.
- How many numbers can I enter?
- There is no fixed limit — the calculator handles as many as you type. For very large datasets, consider a spreadsheet application instead.
