Overview
GrowthMath is a free set of 21 calculators for people who buy traffic, run affiliate programs or sell online: ROAS and break-even ROAS, CPM/CPC/CPA, break-even CPA, affiliate EPC and revenue leak, customer LTV, CAC, churn, Shopify profit, YouTube earnings, engagement rate, A/B test significance and sample size, a UTM builder and a SERP snippet preview. Every tool shows the formula, benchmarks and what the result means - not just a number. It is not an AI chatbot: the math is deterministic and runs locally in your browser, so nothing you type is sent anywhere. Marketers use it alongside AI ad and analytics tools to sanity-check the numbers. No signup, no paywall, and any calculator can be embedded on your own site for free with a short HTML snippet. There is also a free Affiliate Link Checker Chrome extension that lists every affiliate link on a page with its network, tracking ID and rel="sponsored" status.
