How we calculate

Conversions = AI-referral sessions × conversion rate.
Attributed gross profit = conversions × gross profit per conversion.
Net return = attributed gross profit − AEO cost.
ROI = net return ÷ AEO cost. This measures direct attribution; it does not claim that AEO caused every conversion.

An AEO ROI calculator built to be defensible

This calculator separates measured referral value from indirect influence, so the result can be checked and challenged.

Auditable inputs

Use sessions, conversion rate, gross profit per conversion, and cost from your own records. The formula is shown beside the result.

Direct attribution first

The calculator does not turn an assumed traffic lift into revenue. It starts with AI-referral sessions you can observe.

Easy to stress-test

Lower the conversion rate or gross profit value to see how sensitive the result is before presenting it.

How the AI search ROI model works in plain English

Start with AI-referral sessions that your analytics can identify. Multiply sessions by the observed conversion rate, then multiply conversions by gross profit per conversion.

Subtract content, tooling, agency, and allocated staff cost. Divide that net return by the same cost to calculate ROI. A $3,000 net return on $3,000 of spend is 100% ROI.

This is a direct-attribution model. It can undercount people who discover a brand in an AI answer and return later, but it avoids assigning every rise in direct or branded traffic to AEO without evidence.

The assumptions, the math, and the things to watch for.

What does this AEO ROI calculator measure?
It measures direct-attribution ROI: gross profit from tracked AI-referral conversions, minus AEO cost, divided by AEO cost. It does not automatically assign branded-search or direct-traffic growth to AEO.
Where do I find AI-referral sessions?
Use your analytics acquisition report and group known AI referrers such as chatgpt.com, perplexity.ai, claude.ai, and gemini.google.com. Keep the source list and reporting window with your result so it can be audited.
Why use gross profit instead of revenue?
Revenue ignores the cost of delivering the product or service. Gross profit produces a more defensible return figure. Use a finance-approved value and document whether it includes renewals, refunds, and repeat purchases.
Does a positive result prove AEO caused the conversions?
No. Referral attribution shows an observed path, not full incrementality. Compare with a baseline or control and record other changes such as paid campaigns, launches, seasonality, and pricing.
Should I adjust the defaults?
Yes. The defaults reproduce the illustrative example in the linked measurement guide. Replace them with your analytics, conversion, finance, and cost records before reporting the result.
What about AI influence that has no referral?
Track branded search, direct traffic, customer survey answers, and CRM attribution as supporting evidence. Do not add those values to ROI without a defensible method for estimating how much AEO caused.
Is this free?
Yes. The calculator runs entirely in your browser — no signup, no email. If you want a real assessment of where your site stands today across up to nine major AI engines, run the free FixAEO audit.
