AI Invisibility Cost Calculator
Getting started
How to Use This Calculator
Work through Steps 1 to 3 and type your own figures into each box. Each step tells you where to find the number. The boxes start with an example so you can see how the calculation works.
Steps 1 to 3 give you the number of AI answers each month that do not include you.
In Step 4, enter your enquiry rate, close rate and average order value. The calculator turns your missed answers into an annual revenue figure, shown two ways: the top end if you won every one, and a conservative estimate.
Step 1
Demand
Monthly search volume behind your top 20 buying questions.
Where to Find It: Google Keyword Planner, Semrush or SE Ranking. Add up the volumes for the questions your buyers ask before they choose.
searches / month
Step 2
AI Search Users
The share of those searchers using AI tools to make the decision.
Where to Find It: Industry research puts it at 40% to 55% of consumers. Use 40% to stay conservative, or your own survey data if you have it.
% use AI search
Step 3
Your Absence
How often you are missing from those AI answers.
Where to Find It: Run your 20 prompts, signed out, across ChatGPT, Google AI Overviews, Gemini and Perplexity. Count the answers that do not name you.
% not naming you
12,000 searches a month × 40% use AI search × 70% of those answers miss you
= 3,360 answers a month without you in them

How to Read Your Number
This is an estimate of the revenue opportunity, not a forecast. If you only know some of your inputs, keep the worked-example figures for the others and refine them when you have the data.
Before You Start
Run your prompts signed out or in a temporary chat, otherwise you are measuring your own history. Unbranded prompts tell you the truth; branded ones flatter you.
Enquiry, close and order-value figures will vary by business and sector. Annual totals are rounded to the nearest £1,000.
