Patient lifetime value calculator
See what each month of new patients is actually worth over time.
Your numbers
- Patients retained after 12 months
- 28.0
- Value of one month's intake
- $98,000
- Annual value (12 months of intake)
- $1,176,000
Show the math
- Retained patients = 40 × 70% = 28.0
- One month's intake value = 28.0 × $3,500 = $98,000
- Annual value = $98,000 × 12 months = $1,176,000
Illustrative example — figures are hypothetical. Lifetime value blends hygiene recall, restorative, and elective case acceptance; most practices underestimate it by 30–50%.
The lifetime-value formula — and what each input really means
Average production per visit. Not the exam fee — total annual production divided by total patient visits. This captures the blend: hygiene visits at a few hundred dollars and restorative visits at several thousand, averaged across your actual case mix. Pull it from your practice management software for the last twelve months.
Visits per year. Hygiene compliance drives this. A patient on a six-month recall schedule shows up twice a year; the average practice runs lower because recall systems leak. This input is really a measure of how good your re-care engine is.
Years retained — the silent multiplier. The input nobody budgets around and everybody feels. A patient who stays seven years isn't worth slightly more than one who stays three; they're worth more than twice as much, because every additional year is production with zero acquisition cost attached.
Worked example: from $400 a visit to a $4,760 patient
Illustrative example — figures are hypothetical.
| Input | Value |
|---|---|
| Average production per visit | $400 |
| Visits per year | 1.7 |
| Years retained | 7 |
| Lifetime value | $400 × 1.7 × 7 = $4,760 |
Now watch what retention does to that number:
| Annual retention quality | Years retained | Lifetime value |
|---|---|---|
| Strong recall system | 7 | $4,760 |
| Average | 4.5 | $3,060 |
| Leaky | 2.5 | $1,700 |
Same clinical quality, same fees — a $3,060 swing per patient from the recall system alone. This is why the lifetime-value math usually redirects owners' attention from "we need more new patients" to "we're losing the ones we have."
Why lifetime value changes what you can spend
Every acquisition budget is secretly a bet on this number. The arithmetic is simple: cost to acquire one patient = marketing spend ÷ new patients acquired (not cost per lead — cost per patient who actually starts treatment).
Illustrative example — figures are hypothetical: $6,000 in monthly spend produces 40 leads. Twelve become consults; six start treatment. Cost per acquired patient: $1,000. Against a $4,760 lifetime value, that's a 4.8x lifetime payback — comfortable. Against a $1,700 value from leaky retention, it's 1.7x — uncomfortably thin.
Two consequences follow:
- Judge campaigns on lifetime economics, not month-one production. A campaign that looks expensive against first-visit revenue can be cheap against lifetime value. Owners who kill campaigns at 90 days on first-visit math routinely kill profitable acquisition.
- Retention improvements are acquisition-budget improvements. Raise years retained from 4.5 to 7 and every future marketing dollar works harder — the same spend buys the same patients, but each patient is worth $1,700 more.
The two things that move lifetime value most
Retention — the recall engine. Confirmed appointments, re-care follow-up, and lapsed-patient reactivation. This is unglamorous operational work, which is why it's usually the highest-ROI line item a practice ignores. Measure it as the percentage of active patients with a next appointment scheduled; if you don't know that number, start there.
Case acceptance — the treatment-plan conversion. A diagnosed-but-unscheduled crown is production the practice already earned clinically and lost administratively. Lifetime value assumes diagnosed treatment gets scheduled; the gap between diagnosed and accepted is the second-biggest leak after retention.
High-value cases deserve their own math
Blending implant patients into the practice average buries the economics that matter. A full-arch case and a prophy patient are different businesses sharing a roof — different acquisition costs, different case values, different decision journeys. Run the lifetime-value math separately for your high-value segments (implant lead generation is the usual starting point), and let each segment justify its own acquisition budget. The practice-wide average is for planning; the segments are for decisions.
