About GrowthMath

GrowthMath is a small collection of free calculators for people who buy traffic, run affiliate programs or sell online. It is built by people who work hands-on in affiliate marketing, paid acquisition and conversion optimisation.

Every tool follows three rules: it is free with no signup, it runs entirely in your browser, and it explains the formula and what the result means for your business.

The site is supported by display advertising. We also run Traffic Goat, an affiliate program audit service - some tools link to it where it is relevant.
