SEO value comes from organic traffic replacing paid acquisition plus direct conversions. This calculator totals both against SEO spend.
50k SEO annual, 5,000 new monthly organic visitors × 3 PPC equivalent CPC = 180k traffic value + 5k × 2% × 500 AOV = 600k conversion value = 780k total. Net 730k, 1,460% ROI.
SEO compounds over 12-24 months. Year 1 often negative; years 2-3 strongly positive. Typical mature SEO ROI 500-2000% when measured against PPC equivalent traffic cost.
Quick example
With annual seo spend of 50,000 and monthly organic traffic from seo of 5,000 (plus ppc equivalent cpc of 3 and conversion rate of 2%), the result is calculator. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Annual SEO Spend, Monthly Organic Traffic from SEO, PPC Equivalent CPC, Conversion Rate %, and Customer Value. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
What's happening under the hood
Traffic value = monthly visitors × 12 × PPC CPC. Conversion value = visitors × conversion × customer value. Net = traffic + conversion - spend. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Using this as a check-in
Re-run this every three months. A single reading tells you where you stand; four readings tell you whether things are improving. The trend matters more than any individual snapshot.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
£50,000 £ vs 5,000/mo × £3 £ + 2% × £500 £ = calculator.
