Skincare Routine Client Retention Calculator
Measure client retention for a skincare practice over a chosen period while separating returning clients, lost clients, and revenue retained. The calculator uses the standard cohort formula and adds repeat-visit and client-lifetime indicators for a clearer view of relationship durability.
Calculator
Client cohort performanceFormula
Retained clients = ending clients − new clients. Period retention = retained clients ÷ starting clients. Equivalent monthly retention = period retention^(1 ÷ months).
What the result means
Retention describes how much of the opening client base remains active after removing newly acquired clients. Keep the definition of “active” consistent across periods.
Retention is sensitive to cohort definitions, reactivation rules, duplicate records, and the measurement window. This is an operational estimate, not a clinical outcome measure.
Example calculation
Starting with 200 clients and ending with 215 after adding 45 new clients leaves 170 retained clients. Period retention is 85%, with 30 opening clients lost.
Tips for better results
- Define active-client status before counting.
- Exclude new clients from the retained numerator.
- Use the same period length when comparing trends.
- Review retention by first service or practitioner.
- Pair retention with satisfaction and outcome measures.
Frequently asked questions
Why are new clients subtracted from ending clients?
They were not part of the opening cohort, so subtracting them isolates clients who could actually have been retained.
Can retention exceed 100 percent?
A standard cohort retention rate should not exceed 100%; a higher result usually indicates inconsistent counts or reactivated clients.
What is equivalent monthly retention?
It is the constant monthly rate that compounds to the entered retention over the selected number of months.
How should reactivated clients be counted?
Choose a written rule and apply it consistently; depending on your cohort definition, reactivated clients may need to be separated from both new and retained clients.
Is retention the same as repeat booking rate?
No. Retention tracks an opening cohort that remains active, while repeat booking can measure whether visits lead to another appointment.
