How is this calculated?
  • ramp(m) = m ≤ lag ? 0 : min((m − lag) / rampMonths, 1)
  • incrRevenue(m) = traffic × (uplift% × ramp(m) × scenario) × convRate% × dealValue × margin%
  • netGain(M) = Σ incrRevenue(1..M) − monthlyCost × M
  • ROI% = netGain(12) / (monthlyCost × 12) × 100
  • payback = first month where cumulative net gain ≥ 0

Frequently asked questions

How is SEO ROI calculated?

We project the incremental organic traffic from your uplift target, ramped up over time, then convert it to revenue using your conversion rate, average deal value and gross margin. ROI is the 12-month net gain divided by your 12-month SEO cost. The full formula is shown under “How is this calculated?”.

What is a good SEO ROI?

SEO usually pays back over several months rather than immediately, so a healthy program often shows a clear positive 12-month ROI once traffic ramps. Rather than chase a single benchmark number, compare the ROI and payback period against your other channels using your own conversion and margin figures.

How long does SEO take to pay back?

This calculator models a lag before results appear and a ramp-up period (defaults: 3-month lag, 9-month ramp to full speed). Payback is the first month your cumulative net gain turns positive — adjust the lag and ramp in Advanced inputs to match your situation.

Where do the default values come from?

The pre-filled numbers are demonstration defaults that produce a realistic example — they are not claimed industry averages. Replace them with your own figures for an accurate result. Where a field is labelled as an assumption, adjust it to match your business; the methodology page lists every default and its status.

Is my data stored anywhere?

No. Every calculation runs entirely in your browser. Nothing you type is sent to a server — there is no account and no copy of your numbers. If you download the PDF report, only the email you enter on the report form is stored, so we can follow up; your inputs stay on your device.
