About this average calculator
This free average calculator computes the mean of a list of numbers. It’s useful for grades, budgets, sports stats, measurements, and quick data checks. Just paste your values (comma- or space-separated) and get the result instantly.
The average (mean) is calculated with the standard formula: average = sum of values ÷ number of values. For example, the average of 10, 20 and 30 is (10 + 20 + 30) ÷ 3 = 20.
This tool runs entirely in your browser (client-side only). No values are stored or sent, which makes it fast and privacy-friendly for everyday use.
Tip: if you need a weighted average (different coefficients), you’ll need a weighted-mean calculator.
