Average Calculator makes everyday statistics easier to understand. Use our free browser-based tools to calculate averages, compare data and follow the steps behind each result.
More than a single average
Our collection includes arithmetic, weighted, geometric and harmonic means, median, mode, moving averages and trimmed means. You can also explore grades, GPA, growth rates, speed, fuel economy and sports averages.
Built for clear answers
Each calculator explains its inputs, gives a worked example and shows how the result is calculated. No account is required. Calculator inputs are processed locally in your browser.
Understand the limits
Results use floating-point arithmetic and may be rounded. Different statistical conventions can produce different quartiles. GPA scales vary between institutions, so use your own institution’s numeric grade points. Investment tools describe mathematical returns and do not provide investment recommendations.
For important decisions, check your inputs and confirm the result against the relevant official rules or source data.
