SEO ROI Calculator
Turn traffic estimates into revenue projections — and make the business case for content.
Ground this with our Traffic Potential Calculator.
Visitor → customer/lead. Content sites typically see 0.5–3%.
Customer LTV, or lead value if you sell later.
Writing, tools, editing — everything content costs you per month.
Remember that SEO compounds: the articles you pay for this month keep producing traffic in month 24 at zero marginal cost, so real-world ROI typically climbs well above this steady-state estimate. Runs entirely in your browser.
What this tool does
The SEO ROI Calculator turns SEO assumptions into a revenue projection you can defend in a budget meeting. Enter expected monthly organic visits, your conversion rate, average customer value, and your monthly content investment, and it calculates monthly and annual revenue, profit, ROI percentage, and break-even point — instantly, with every assumption visible and adjustable.
SEO gets funded when it's framed as an investment and cut when it's framed as an expense — and the difference is usually whether anyone did this math. The calculation also enforces honesty in both directions. Optimists discover that 1,000 visits at a 1% conversion rate is ten conversions, not a hockey stick; skeptics discover that content compounds — the same article that breaks even in month four keeps producing traffic for years at zero marginal cost, which is what makes SEO's ROI curve fundamentally different from paid channels that stop the moment spending stops.
Model conservative, expected, and optimistic scenarios by adjusting the inputs — everything runs locally in your browser with no signup. Pair it with our Traffic Potential Calculator to ground the visits number in real data, and with SirWritesALot to make the content side of the equation cheaper.
