Free SEO ROI Calculator

Our SEO ROI calculator turns your own numbers into a clear return picture, and helps with the one input most people cannot guess: the conversion rate. Pick your business type (ecommerce, B2B SaaS, lead generation, local services, or other) and the tool pre-fills a typical conversion rate from published 2026 benchmark studies, which you can override with your own data. Then you enter your monthly SEO spend, the organic visitors you expect, your average order value, and an optional profit margin. The tool works out how many conversions that traffic produces, the revenue and profit it generates, your net gain after spend, and the return on investment, all updating live. The core formula is simple: ROI equals (return minus cost) divided by cost, shown as a percentage, alongside ROAS (revenue divided by spend).

Every figure comes from you. The calculator does not predict your traffic or invent a growth curve, because no honest tool can promise rankings. Instead it does the math on the assumptions you provide, so you can test scenarios: a higher conversion rate, a bigger order value, a lower spend, and see how the return changes. One important caveat it states plainly: SEO takes months to ramp, so your early months usually earn less than the steady-state number here. It all runs in your browser, so nothing you enter is uploaded.
