Measure how well a specific group of nail clients returns after becoming eligible for another visit. Enter the original cohort, completed return visits, and average value of a returning appointment. The calculator reports retention rate, clients not retained, and revenue tied to returning clients. Keeping the cohort and return window consistent makes the result useful for comparing technicians, service types, promotions, or time periods.
Choose a nail salon 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.
Use clients from a clearly defined starting period who had enough time to complete the return interval you are measuring.
For strict retention, count completed return visits and track future bookings as a separate leading indicator.
No. For client retention, count each eligible client once, even if that person completed several appointments.
Match it to the normal service cadence and apply the same window to every cohort you compare.
Returning clients may choose lower-priced services, use discounts, or visit less often, so retention and revenue should be reviewed together.
