How to Estimate the Value of Your Past-Patient Database
Your booking system holds patients who already know you. Here is simple math to size the opportunity, using your own numbers rather than ours.
Past patients already know your clinic, so reaching them can cost far less than finding someone new. But a contact list isn't money in the bank. A simple, honest estimate will tell you whether it's worth pursuing.
The basic math
Reachable contacts × response rate × average package value = estimated revenue
Our calculator uses 1.2% of contacts booking a $3,200 package as its working assumption.
| Contacts | Clients at 1.2% | Revenue at $3,200 |
|---|---|---|
| 1,000 | 12 | $38,400 |
| 2,500 | 30 | $96,000 |
| 5,000 | 60 | $192,000 |
These figures are the output of that assumption, not a prediction. Your rate could be much higher or lower.
Make the estimate yours
Clean the list first
Your real starting number is smaller than your total contact count. Remove duplicates, invalid numbers, opt-outs and patients who shouldn't be contacted. Then check what consent you hold, because this decides who you can text at all.
Segment it
Not every past patient is equally likely to respond. Useful cuts include time since last visit, services received, total spend and active memberships. A patient who bought a high-ticket treatment last year is a very different prospect from someone who came once five years ago.
Test before you scale
Pick a small, consented segment and run a test. Measure:
- Delivery rate
- Reply rate
- Opt-out rate
- Booked consultations
- Show rate
- Packages sold and their margin
Replace our 1.2% with your own result, then rerun the math.
Revenue isn't EBITDA
A $96,000 campaign doesn't add $96,000 to your valuation. Subtract product, provider and marketing costs to find the profit. Then ask whether it will repeat, because buyers may treat a one-time campaign differently from recurring revenue.
That's why reactivation is often best seen as a way to raise near-term cash and test demand, while you build recurring programs that can support your valuation.
Protect the relationship
These are your patients, so what you send reflects on your clinic. Keep messages relevant, respect opt-outs at once and avoid sensitive assumptions about someone's health or body. Read our compliance checklist before sending anything.
