Patient Acquisition Cost (PAC) — the fully-loaded cost of acquiring one new patient.
Patient Acquisition Cost is ad spend + agency fees + platform tooling + inside-sales cost, divided by newly-registered patients who actually consulted. Different from CAC because PAC counts consultations, not leads. ICG portfolio median PAC in 2026 sits at Rs 2,800-4,500 for consultation-driven specialties.
How it works.
Most clinics quote a CPL number and call it acquisition cost. It is not. A lead is not a patient. In a healthy dental practice, roughly one in three leads makes it to the chair. In IVF the number is closer to one in six. PAC forces the honest arithmetic — count what you actually spent, divide by patients who actually walked in, and read the number that comes out. Marketers argue the four-bucket definition is unfair because it loads agency and tooling into the cost of a paid-media lead. Founders argue those buckets are real cash out the door. The founders are correct.
- Isolate the source-tagged patient. Only count patients whose registration form or CRM record traces back to a marketing source. Walk-ins and word-of-mouth belong in a separate bucket.
- Sum the four cost buckets. Direct paid-media spend, agency retainer, platform tooling (CRM + WhatsApp API + IVR + dashboarding), inside-sales salaried time. For the exact window being measured.
- Anchor the denominator to consultation, not lead. A lead who did not consult never became a patient. If they consult in a later window, count them in that later window.
- Check consent scope. DPDP-compliant patients only. If a patient's consent record does not permit paid-attribution use, they do not enter the denominator.
- Segment by specialty. A blended PAC across dermatology and IVF is not useful. Split by specialty, then by channel.
- Read alongside pLTV. PAC alone is a cost number. PAC-to-pLTV ratio is a viability number. The ratio is what matters.
Why it matters for
Indian healthcare.
The Digital Personal Data Protection Act 2023 changed what PAC even means. Sections 5-9 of the Act require purpose-limited consent — a patient consenting to be treated is not automatically consenting to be counted as a paid-media acquisition. That distinction sits at the heart of what a defensible PAC denominator can look like. If the consent form bundles "treatment", "follow-up communication", and "marketing attribution" into one checkbox, DPDP-Rule-compliant lawyers will not sign off on that consent, and any PAC number built on it is retrospectively questionable. NMC's Code of Ethics adds a second layer — a doctor cannot solicit patients directly, so any PAC attribution that runs through the treating physician's own promotional channel invites a state-council flag. ASCI adds the third — unsubstantiated outcome claims in the ad that acquired the patient can invalidate the acquisition itself. A clean PAC calculation is therefore not just a marketing exercise; it is the audit trail that says the patient in the denominator arrived through a compliant path.
How ICG uses this.
PAC is computed on the HealthPro 360 operating layer, which owns the consultation-registration event, and cross-referenced with Meta Catalyst IQ for spend and CPQL context. Every ICG-managed engagement runs against a specialty-tagged PAC target set on Day-0, with the four cost buckets pre-loaded so no bucket is hidden. For clinics running the ICG Setup engagement, the ICG Dental Clinic Setup Calculator is the fastest way to model expected PAC against realistic Year-1 patient volumes before the first ad rupee is spent. Related term: CPQL, which sits one step upstream in the funnel.
| Specialty band | Typical PAC range | Lead-to-consult ratio |
|---|---|---|
| Dental · single clinic | Rs 1,800-3,200 | 30-40% |
| Dermatology · chain | Rs 2,400-4,200 | 25-35% |
| Orthopaedics · hospital | Rs 4,500-8,500 | 20-28% |
| IVF · single centre | Rs 18,000-32,000 | 15-22% |
| Cardiac · tertiary | Rs 22,000-45,000 | 12-20% |
Frequently asked questions.
How is PAC different from CAC?
CAC (Customer Acquisition Cost) counts anyone who paid — which in healthcare gets muddled by walk-ins, referrals, and family members added later. PAC counts only patients who registered against a marketing source and actually consulted. It strips out the ambiguity that makes CAC unreliable for clinics. ICG portfolio median PAC in 2026 sits between Rs 2,800 and Rs 4,500 for consultation-driven specialties.
What sits inside the fully-loaded PAC?
Four buckets. Direct paid-media spend (Meta, Google, YouTube). Agency retainer or performance fees. Platform tooling — CRM, WhatsApp Business API, dashboarding, IVR. Inside-sales cost — the salaried front-desk time attributable to that lead pipeline. Add them, divide by patients who actually consulted in the window, and the result is a number the founder can sit with.
What is a good PAC for an Indian clinic?
PAC only makes sense against pLTV. A dental clinic with a Rs 8,000 lifetime value cannot afford a Rs 4,500 PAC unless referral loops offset it. An IVF centre with a Rs 4,50,000+ lifetime value can defensibly run PAC at Rs 25,000 or more. The right question is not the absolute number — it is the ratio of pLTV to PAC, and whether that ratio holds after the retention curve is honestly modelled.
How does DPDP consent affect PAC calculation?
A patient only counts in the PAC denominator if their consent scope permits marketing attribution — the Digital Personal Data Protection Act 2023 requires purpose-limited consent, and "attribution to a paid campaign" is a distinct purpose. If consent was only granted for treatment communication, that patient is a treated patient but cannot legally be attributed to a paid-source PAC calculation. Which is why the consent form design decides what the PAC denominator can honestly be.
