How to use this calculator

Enter monthly SEO spend, time horizon, organic traffic, conversion rate, value per conversion and gross margin. The result shows ROI, profit, payback and a conversion-improvement scenario.

Why payback period matters

SEO is an investment that compounds; payback period tells you when the program turns net-positive. The benchmark bar grades your ROI.

Sources

SEO ROI and conversion benchmarks are sourced from public industry data including HubSpot and Ahrefs research reports, versioned in the platform configuration.

Frequently asked questions

How is SEO ROI calculated?

ROI% = (attributable revenue − SEO investment) ÷ SEO investment × 100, over your chosen time horizon. Revenue = traffic × conversion rate × value per conversion × gross margin.

What is a good SEO ROI?

SEO commonly returns 2–5× over 12+ months once content compounds. The benchmark bar compares yours to a typical program.

Why include a time horizon?

SEO compounds slowly, so short horizons understate ROI. Modeling 12+ months gives a fairer picture of payback.
