Planning tool only Figures are for illustration. They are not financial, tax, legal, or clinical advice, and they may not match your contracts or accountant’s treatment.

What this calculator covers

This patient acquisition cost calculator is publisher content for UK private clinics, therapists, and physios. You supply acquisition spend and new patients acquired. It reports cost per new patient using the simplified assumptions described below—not as a substitute for an accountant, solicitor, or clinical record.

Patient acquisition cost (PAC) helps compare channels. Sum the spend you attribute to acquisition and divide by new patient registrations you believe those efforts produced.

Organic word-of-mouth will skew results if excluded inconsistently.

What this model does not do

This patient acquisition cost calculator is original publisher copy for UK private clinic administration. It does not measure creative quality or ad-auction dynamics. Ratios are only as good as how you count enquiries and bookings.

The form cannot see your contracts, payer mix, or diary software. If a clause matters and there is no field for it, the output will not include it.

How it works

  1. Enter acquisition spend

    For this Patient acquisition cost model, enter acquisition spend and new patients acquired. Keep those definitions consistent with your diary or management accounts.

  2. Read cost per new patient

    The patient acquisition cost model then reports cost per new patient. The arithmetic runs in your browser; we do not receive the numbers you type.

  3. Check against marketing & growth records

    Treat cost per new patient as planning figures for marketing & growth conversations, then confirm VAT, contracts, and filings with your own records and qualified advisers.

Context and how to use this

PAC divides acquisition spend by new patients attributed to that spend. Organic word-of-mouth will distort PAC if you omit it from both numerator and denominator.

Useful for comparing channels quarter to quarter with stable definitions.

Common questions

Blended versus marginal PAC?
This is simple average PAC. Marginal cost of the next patient may differ at higher spend.
Include staff time?
If you want a fully loaded PAC, add an hourly cost for marketing labour to the spend field.
