Cost Per New Patient (CPNP)
Cost per new patient (CPNP) is total marketing spend divided by new patients acquired over the same period. The single most important practice marketing metric — and the one most practices cannot calculate accurately.
CPNP = (total marketing spend) / (new patients from marketing). The "from marketing" qualifier is what trips most practices up — referrals from existing patients should not count against the marketing budget. Tracked properly, CPNP tells you which channels actually work.
Healthy benchmarks by specialty
Chiropractic: $80-200. Dental general: $150-300. Dental implant/cosmetic: $300-600. Med spa: $80-200. Functional medicine: $200-500. Optometry: $50-150. These vary widely by market and channel mix.
Tracking it correctly
(1) Every new patient gets asked "how did you find us?" and the answer is recorded. (2) Phone calls are tracked with call tracking numbers per channel. (3) Form submissions tagged with UTM source. (4) Walk-ins counted as "organic/word of mouth" unless they explicitly cite a campaign.
How to lower it
Two levers: convert more of existing traffic (better booking flow, faster response time, more compelling website), or shift spend from expensive channels to cheaper ones (Google Ads → SEO, paid social → referral programs).
What AI changes
AI voice and AI texting raise conversion rate on inbound interest dramatically — a call that used to go to voicemail and never convert now becomes a booked appointment. Same marketing spend, lower effective CPNP.
