Patient lifetime value is the profit one patient brings your clinic over the whole relationship. A simple formula: average revenue per visit, times visits per year, times years the patient stays, times your profit margin. For example, ₹10,000 per visit, three visits a year, for two years, at a 60% margin gives a lifetime value of ₹36,000. Recalculate it every quarter.
Ask a doctor what a new patient is worth and most will say the fee for the first treatment.
That is the wrong number. And it leads to the wrong decisions: under-spending on marketing that would have paid for itself, or over-spending on marketing that never could.
Patient lifetime value tells you what a patient is really worth to your practice. Once you know it, decisions about ads, staff and retention stop being guesses.
What is patient lifetime value?
It is the profit a typical patient brings your clinic across the whole time they stay with you. Not revenue. Profit. Because a ₹1 lakh treatment that costs you ₹90,000 to deliver is not worth ₹1 lakh.
Here is the simple, profit-based formula I use:
Lifetime value = average revenue per visit × visits per year × years the patient stays × profit margin
Use the margin as a decimal. A 60% margin is 0.6.
How do you calculate it, step by step?
- Average revenue per visit. Take the last twelve months of revenue and divide by the number of visits in that time.
- Visits per year. Divide total visits by the number of individual patients who visited in the year.
- Years the patient stays. Look at how long patients typically keep coming back, from their first visit to their last. If you do not have the history, start with a careful estimate and refine it as the data builds.
- Profit margin. Profit as a percentage of revenue, from your monthly books.
- Multiply.
Example: your average visit brings in ₹10,000. Patients visit 3 times a year and stay 2 years. Your margin is 60%.
- ₹10,000 × 3 = ₹30,000 a year
- ₹30,000 × 2 = ₹60,000
- ₹60,000 × 0.6 = ₹36,000 lifetime value
How does it work for different kinds of practice?
The formula is the same. What feeds it is different.
| Practice type | What drives lifetime value | Watch out for |
|---|---|---|
| Session-based (skin, physiotherapy) | Many visits per year, plan completion, maintenance plans | Patients stopping halfway |
| Procedure-based (hair transplant, cosmetic surgery) | A high first ticket, then related care and protection plans | Counting the procedure as the whole relationship |
| Surgical (joint replacement, urology) | The surgery, reviews, the second knee or prevention programme, family members | Losing touch after discharge |
| Long relationship (dental, family medicine) | Years the patient stays, family members joining | Patients drifting with no recall system |
One rule keeps your maths honest: keep your units consistent. If your average ticket already covers a whole plan of six sessions, do not multiply it by six visits again.
Example, procedure-based: say a hair transplant brings in ₹1.5 lakh, and over the next two years the average patient also spends ₹30,000 on a protection plan and scalp care. Total revenue per patient: ₹1.8 lakh. At a 60% margin, lifetime value is about ₹1.08 lakh. That is very different from treating the patient as worth one procedure and nothing else.
How much can you spend to get a new patient?
This is why the number matters.
The benchmark I use is that your cost per new patient should be roughly 10 to 20% of a patient's first-year value. Say a patient is worth ₹5 lakh to you over the first year. At the 10% end, you would aim to keep acquisition cost below ₹50,000.
Then look at the ratio of lifetime value to acquisition cost:
- Around four to five is a good ratio.
- Below three is a warning sign. Check whether your overheads still leave you enough profit.
- Above five can mean you have room to spend more on growth.
Example: if lifetime value is ₹36,000 and you spend ₹9,000 to get each new patient, your ratio is 4. Healthy. If acquisition cost creeps up to ₹15,000, the ratio drops to 2.4, and something needs fixing: lead quality, conversion or retention.
Do not read the ratio alone. A ratio of seven on a tiny budget is not automatically better than a ratio of three on a large one. Look at the total profit created.
What mistakes do clinics make when calculating lifetime value?
- Using revenue instead of profit. It makes every patient look more valuable than they are, and justifies ad spend that never pays back.
- Double counting visits. Multiplying a package price by the visits it already includes.
- Using one month of data. Lifetime value depends on how long patients stay. A single month tells you almost nothing.
- One number for the whole clinic. A laser patient and a surgery patient behave very differently. Calculate it per service line as well as overall, so you know which treatments are worth advertising.
- Ignoring referrals. The formula does not count the family member who books because of this patient. Track referral rate alongside it, so you do not undervalue your happiest patients.
How do you increase patient lifetime value?
Every part of the formula can grow, and each one grows from the six sources of lifetime value:
- Revenue per visit: better packaging and plans instead of single sessions.
- Visits per year: plan completion, follow-ups and maintenance.
- Years the patient stays: recall calendars, long-term plans and staying in touch.
- Margin: pricing on value, controlling costs and never discounting.
- And beyond the formula: family, friends and reviews, which bring new patients who cost you almost nothing to acquire.
Recalculate lifetime value every quarter, using a longer history each time. Then compare it with your cost per new patient every month.
Getting these numbers right, and deciding what to do with them, is the starting point of our growth consulting. Raising lifetime value itself is what our retention, reactivation and referrals work is built for. The full set of numbers is in Chapter 2 of Good Doctors Go Broke.
The short version
- Lifetime value = revenue per visit × visits per year × years the patient stays × margin.
- Use profit, not revenue, and keep your units consistent.
- Aim for cost per new patient around 10 to 20% of first-year value.
- A lifetime value to acquisition cost ratio of four to five is healthy; below three is a warning.
- Recalculate every quarter and grow it through completion, maintenance, related care and referrals.
Frequently asked questions
What is a good patient lifetime value for a clinic in India?
There is no single good number, because it depends on your speciality, pricing and how long patients stay. What matters is the relationship between lifetime value and what it costs you to get a patient. A ratio of around four to five is healthy. Below three is a warning sign that acquisition is too expensive or retention too weak.
Should patient lifetime value use revenue or profit?
Use profit. Multiply the lifetime revenue by your profit margin, because a high-revenue treatment with high delivery costs may be worth far less than it looks. Profit-based lifetime value tells you how much you can genuinely afford to spend to acquire a patient while still running a healthy practice.
How often should I recalculate patient lifetime value?
Update it every quarter, using as long a history as you have. Lifetime value depends on how long patients stay, so it needs more than a month of data to mean anything. Compare it every month with your cost per new patient, so you notice early if acquisition costs are creeping up.
How do I calculate lifetime value for a one-time surgery patient?
Start with the surgery revenue, then add what the typical patient spends afterwards: reviews, physiotherapy, related care such as a second knee, and any prevention programme. Multiply the total by your margin. Then remember the family members and friends that patient refers, who often cost you almost nothing to acquire.
