Almost no clinic can answer this, and it is not carelessness. Google Analytics cannot produce the number on its own — it needs your booked-patient count reconciled against what you spent, and nothing does that automatically.
Below is a two-part answer. First, work out roughly where you stand using your own figures. Then see the reporting that measures it properly, every month.
Clinics that track CAC report 50 new patients a month against 35 for those that don't — 42.9% more. Applied to your own numbers, that difference is worth the figure above each year.
Figures from the UK Private Practice Barometer 2026 (715 clinic owner responses, 358 full completions, collected August–November 2025). The relationship between tracking CAC and higher turnover is an association observed in that survey, not proof of cause. Measuring your cost per patient does not by itself create patients — it tells you which half of your spend to stop. This calculator is a planning model, not a forecast of your results.
That figure is a model built on averages. The real one is specific to your clinic, and it changes every month. Which means it is not something you work out once — it is something you need reported to you.
Every clinic we work with gets a login to this. It updates monthly, and the bottom line of it is the number the calculator above could only estimate.
The clinic on screen is a worked example, not a real client account. Treat the numbers as illustrative — they are there to show the layout. The report itself, and every figure it pulls, is exactly what you would get.
No sign-up, no email gate. If you would rather read than watch, the four things it covers are below.
I will tell you which of your numbers are worth tracking, which are noise, and whether there is anything here worth doing at all for a clinic your size. No deck, no pitch.
