Measure how effectively your business keeps salon chair clients over a chosen period. This calculator uses a starting-client cohort to avoid counting new acquisitions as retained clients, then shows churn, net client-base movement, and a monthly-equivalent retention rate. It is useful for tracking rebooking behavior after maintenance cycles, comparing periods, and separating client loyalty from new-client marketing.
Retention isolates the share of the original cohort that returned. Net change can still be positive when retention is weak if enough new clients were acquired, so both measures should be reviewed together.
Define “active,” “returned,” and the measurement window before counting. Changing definitions makes period-to-period comparisons misleading.
With 120 starting clients, 84 returning clients, 30 new clients, and 110 ending clients over three months:
Count a starting client as retained only if that same client completed another qualifying visit during the selected period.
No. New clients can be entered for context, but they are excluded from the retention-rate numerator and starting-client denominator.
Use a period that matches the normal return cycle, such as a month, quarter, or extension maintenance window, and use it consistently.
No. Retained starting clients cannot be greater than starting clients; the calculator flags that input combination.
Ending clients minus starting clients gives net client change, while ending clients divided by starting clients gives the ending-base ratio.
| Measure | Uses new clients? | Purpose |
|---|---|---|
