What Is Cost per New Patient? Definition and Formula
Cost per new patient is the marketing money spent to get one new patient through the door, calculated as total marketing spend divided by new patients from that spend, over the same period.
Cost per new patient is what you paid in marketing for each new patient who actually came in. Rehab Lab, a cash PT client with clinics in Milwaukee and Appleton, Wisconsin, ran a cost per new client of $342.50 in Milwaukee and about $500 in Appleton in June 2026. Those numbers mean nothing alone. Against packages that start at $5,000, they are a bargain.
How do you calculate cost per new patient?
Cost per new patient = total marketing spend / new patients from that spend, over the same period. Worked example: a chiropractic office spends $3,000 on Facebook and Google ads in a month and 20 new patients from those ads arrive, so $3,000 / 20 = $150 per new patient. Two rules keep the number honest. Count arrivals, not bookings. And keep referrals and walk-ins out of the ad calculation, or the ads get credit for patients they did not bring. If you track by channel, compute it per channel too.
| Item | Example |
|---|---|
| Ad spend for the month | $3,000 |
| New patients from ads who arrived | 20 |
| Cost per new patient | $150 |
What is the difference between cost per lead and cost per new patient?
Cost per lead counts people who raised their hand; cost per new patient counts people who walked in. The gap between them is your front desk, your speed to lead and your arrival rate. A $20 lead that becomes a patient one time in ten costs $200 per new patient. A $40 lead that converts one time in three costs about $120. That is why we judge ads on cost per new patient, not cost per lead.
How do you know if your cost per new patient is good?
Compare cost per new patient with what a new patient is worth, not with other clinics. Rehab Lab's June 2026 STEMwave shockwave campaign cost $150 to $180 per client against a $2,850 plan of care, so the clinic doubled the spend. A $150 cost is a problem for a clinic whose patients average $400 in total collections and fine for one whose plan of care is $2,000. The Rehab Lab case study walks through how those numbers were tracked, and how many new patients per month helps set the target.
Questions owners ask
Is cost per new patient the same as patient acquisition cost?
Yes, most clinics use the two terms the same way. Some include staff time and software in acquisition cost; decide what you include and keep it consistent.
Should I count new patients who booked or who arrived?
Count arrivals. A booked patient who never shows cost you the same ad money and brought in nothing, so counting bookings makes the number look better than it is.
What is a good cost per new patient?
It depends on what a new patient is worth to you. Compare it with your average plan of care or first-year collections per patient, not with another clinic's number.
