SEO ROI Calculator
Start with a quick revenue-to-spend scenario, then explore an optional monthly plan with explicit incremental traffic, contribution margin and costs. Both models depend on your assumptions, not guaranteed SEO outcomes.

Build a monthly acquisition scenario
This detailed scenario is independent of the quick estimate above. All defaults are editable examples. Additional organic visits follow a linear ramp, then stay at target. Costs include only the amounts entered here.
Results stay on your device. Copy, download or print includes your inputs and the stated assumptions. Enquiries do not automatically attach your inputs.
Example, assumptions and model details
At its default inputs over 12 months the quick model projects $115,200 extra revenue; at a 40% gross margin that is $46,080 gross profit, or $16,080 profit after $30,000 of SEO spend (about +54%).
Forecast traffic, conversion and timing are user assumptions. Observed attribution, seasonality, execution and competition can make outcomes materially different.

How to use this tool
Use analytics for current organic traffic and CRM or sales records for conversion and customer value. Keep periods consistent.
Enter expected additional traffic and conversion assumptions. Zero is valid; growth is a scenario, not a promise.
Compare revenue, contribution and costs using the stated model. Test a lower-growth case before making a spending decision.
How the projection works
The model grows your current organic traffic by the target percentage, converts the extra visits into enquiries at your conversion rate, closes them at your close rate and values them at your average customer value.
Extra visits build up evenly over the first 9 months, then hold at your target for the rest of the period. The headline is profit after SEO spend: extra revenue at your gross margin, minus the monthly SEO investment over the period. The optional monthly model below uses your incremental traffic ramp, conversion, margin and costs. It reports contribution after marketing and a payback month only when the scenario reaches one. Retained traffic beyond the horizon is not modelled.
Frequently Asked Questions
Straight answers about what this tool measures, the assumptions behind it, and what to do with the result.
Explore SEO revenue scenarios with explicit traffic, conversion, value and cost assumptions. Keep revenue multiples separate from profit ROI.
At the default inputs over 12 months, extra visits build up to 800 a month over the first 9 months: $115,200 of extra revenue, or $46,080 at a 40% gross margin. Less $30,000 of SEO spend, that leaves $16,080 of profit after spend, a return of about +54%. Revenue on its own is not profit.
Forecast traffic, conversion and timing are user assumptions. Observed attribution, seasonality, execution and competition can make outcomes materially different.
