About Us

What is Average Calculator?

The site’s main calculator is the Average Calculator on the homepage, with four modes: Standard, Percentage, Weighted, and Geometric. It shows the mean, median, mode, range, sum, count, and population standard deviation for your numbers.

What else is here?

There are 14 more free calculators, each on its own page with its formula, a step-by-step method, and a worked example — covering standard and scientific calculation, fractions, ratios, BMI, age, dates, GPA, loans, compound interest, tips, discounts, unit conversion, and triangles. The homepage also carries a full guide to mean, median, and mode.

How the calculators work

Everything runs in your browser. Your numbers are never sent to a server, stored, or tracked — there are no accounts, no cookies, and no analytics on this site. You get the answer and understand how it was reached.
