SEO ROI Calculator | Model Your Return by Month

Model the return on an SEO or link building budget, including the ramp-up period and break-even month. Runs entirely in your browser — nothing is uploaded, nothing is stored.

Why SEO needs a ramped model

Paid media returns from day one and stops when the budget stops. SEO returns nothing for the first months, then compounds and keeps returning after the invoice ends. A flat spend-versus-revenue comparison always makes SEO look worse than it is, so this calculator phases the gain in and reports the break-even month alongside the year-two run rate.

Inputs that make the model honest

• Traffic lift — 30–60% over six to twelve months is realistic for a site with existing authority; be far more conservative for a new domain.
• Conversion rate — use your actual organic figure from analytics, not a site-wide average inflated by paid brand traffic.
• Order or lead value — for lead generation, use lead value (deal value multiplied by close rate), not deal value.

What the calculator deliberately excludes

Brand search lift, assisted conversions, the content asset you keep, and the compounding effect of links acquired this year still working in three years. Real returns tend to sit above this model, which is the right direction for a forecast to be wrong in.

From forecast to campaign

Pair the ROI figure with per-keyword upside from the traffic and CTR estimator, then tell us your targets and we will send back the link plan and timeline behind those numbers.
