A single treatment can look like a small sale. A client who returns every few months for years is worth far more. Client lifetime value puts a number on that.
A simple formula
Lifetime value = average contribution per visit × visits per year × average years a client stays
Use contribution margin, not revenue, so the result reflects what the client actually adds after product and provider costs.
For example: average contribution per visit of $180, four visits a year and an average client relationship of three years gives a lifetime value of $2,160.
Where to get the numbers
- Average contribution per visit: from your service-level margin analysis
- Visits per year: from your POS, for clients active in the past year
- Average years a client stays: estimate from how long clients keep returning; start with a conservative figure
Segment it
Lifetime value differs by client type. Calculate it separately for:
- Members versus non-members
- Clients who started with injectables versus skin treatments
- Clients by acquisition channel
These differences show where to focus marketing and retention.
How to use it
Marketing
Compare lifetime value with client acquisition cost by channel. A channel with higher CAC can still be the best investment if its clients stay longer and spend more.
Retention
Small increases in visit frequency or retention raise lifetime value significantly. Rebooking at checkout, treatment plans, reminders and personal follow-up often pay off more than new-client campaigns.
Service design
If clients who start with a certain service tend to stay longer, that service may deserve a place in your introductory offers.
Review yearly
Recalculate lifetime value annually, or when pricing, membership design or your service mix changes significantly.
