Dental patient lifetime value for private practices
Dental patient lifetime value is the margin a new patient brings the practice over the whole time they stay with you: the first treatment, hygiene and recall visits, a membership plan, later treatment, and anyone they refer. You can estimate it from your own records, and you should, because the figures quoted in marketing content are not about your patients.
It's a useful number and an easily abused one. Used well, it tells you which patients are worth acquiring and how much retention is worth. Used badly, it justifies acquisition costs the practice can't pay for in cash this year. Both uses are covered below, as part of tracking ads to booked treatment. For the method behind every stage, see how to measure dental marketing.
Definition
The main parts, each defined for a practice:
| Component | What it means |
|---|---|
| First treatment | The course of treatment that brought them in |
| Recall | The routine examinations a patient returns for at an agreed interval |
| Hygiene | Scale and polish or periodontal appointments with a hygienist or therapist |
| Plans | Monthly membership or capitation fees, if you offer a plan |
| Later treatment | Anything they go on to have: crowns, aligners, implants, whitening |
| Retention | How many of the group are still attending each year |
| Referral | New patients they introduce, where the referrer is recorded |
The dental marketing glossary carries the short definition.
Calculating it from your records
The method uses a cohort: a group of new patients who joined in the same period, followed forward in time. Pick a cohort old enough to have a history, say patients who joined three or more years ago, so you're measuring what happened rather than guessing.
Illustrative figures, not benchmarks. The table uses invented round numbers for a cohort of 100 new patients.
| Illustrative figures, not benchmarks | Year 1 | Year 2 | Year 3 | Total |
|---|---|---|---|---|
| Patients still attending | 100 | 70 | 55 | |
| Contribution from the cohort | £30,000 | £9,000 | £8,000 | £47,000 |
| Contribution per original patient | £300 | £90 | £80 | £470 |
Four points make the estimate hold up:
- Use contribution, not revenue. Same reason as in whether the marketing paid for itself: lab fees and clinician pay are real.
- Split by first treatment. A patient who arrived for an implant consultation and one who came for a check-up are different populations. One blended figure hides that.
- Split by source where you can. Patients from referrals, search and social may stay for very different lengths of time. This only works if the source was recorded when they joined.
- Keep private and NHS separate in a mixed practice. They have different fees and different reasons for staying.
Two components need care. Plan income is recurring, so count the fees actually received from the cohort, not the plan price multiplied by the months you hope they stay. Referral value only counts where the referrer was recorded against the new patient; if your system has no field for it, leave referrals out rather than estimating them, and start recording them now.
Your practice management system (PMS), the software that holds your appointments, treatment and payments, holds everything you need. Most will export treatment income by patient and date; a spreadsheet does the rest.
When to use it
LTV earns its place in three decisions.
| Decision | How LTV helps |
|---|---|
| Which patients to target | If implant patients from one channel stay and return far more than another, that channel deserves a closer look |
| How much retention is worth | Recall reminders, hygiene capacity and plans all protect the later years of the table |
| The ceiling on acquisition cost | LTV sets the upper limit of what one new patient could ever be worth acquiring for |
That third use is the most useful and the most dangerous, which is why it needs a second number next to it.
When not to
Do not use lifetime value to justify an acquisition cost the practice can't carry in cash. LTV is earned over years. Ad spend is paid this month. A practice that pays more to acquire a patient than that patient returns in the first year is lending money to its own future, and has to fund the gap from somewhere.
So I always put LTV next to payback period: how long a new patient takes to return, in contribution, what it cost to acquire them. If the payback period is longer than the practice can fund, the acquisition cost is too high, whatever the lifetime figure says.
| Misuse | Why it misleads |
|---|---|
| Borrowing an industry LTV figure | It describes someone else's patients, prices and retention |
| Projecting from a young cohort | A year-one cohort has no retention history yet; the later years are guesses |
| Using revenue | Overstates value by the full cost of delivering treatment |
| Folding LTV into monthly ROI | Makes a losing month look profitable with money not yet earned |
| Reporting projected value as if it were booked | It has not happened yet, and Google Ads will not import an offline conversion uploaded more than 90 days after the last click1, so later treatment cannot be sent back to the ad that way |
Lifetime value is a planning number. The monthly question, whether this month's spend produced treatment that paid for it, still has to be answered on its own.
