Patient acquisition cost calculator
Divide marketing and sales spend by new patients acquired in the same period.
Introduction
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.

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.
