Measure repeat behavior for a defined cosmetic clinic cohort without mixing clients who have not yet had time to return. Enter eligible clients, those who completed a qualifying repeat visit, and average revenue from a return appointment. The calculator shows retention rate, clients not retained, and return revenue. Choose a window that matches the treatment cadence and compare only cohorts built with the same eligibility and completion rules.
Choose a cosmetic clinic client cohort whose normal return window has passed. Enter how many were eligible, how many returned, the observation period, and average returning-client spend.
The rate shows the share of clients in the selected cohort who completed another visit within the measurement window.
Define eligibility and the return window consistently. A client who is not yet due to return should not be counted in the denominator.
If 200 clients were eligible to return and 140 returned, retention is 70%. At $85 average spend, those returning clients generated an estimated $11,900.
Include clients whose expected return or follow-up interval ended during the measurement window.
For strict retention, count completed qualifying visits and report future bookings separately.
Only if that is the behavior you intend to measure; otherwise separate required follow-ups from elective repeat treatments.
No. Count each eligible person once for client retention, regardless of the number of repeat visits.
Recommended and preferred return intervals differ, so combining unlike services can hide meaningful changes.
