Client Retention Rate

It measures how many customers come back after their first visit — repeat clients are cheaper than constantly finding new ones.

Formal definition

Client retention rate equals returning clients divided by total active clients in the period, expressed as a percentage.

Why it matters

Salons, clinics, and spas with retention below about 65% often spend heavily on ads just to stay flat.

Where you see it

• Spa and salon management software reports
• Dental and veterinary practice dashboards
• Subscription and membership business reviews
• Customer success team KPIs
• Marketing analytics for service businesses

Worked example

1. Total active clients this year: 400.
2. Clients who booked at least twice: 280.
3. Retention rate = (280 ÷ 400) × 100 = 70%.
4. Interpretation: 70% of clients returned — 30% were one-and-done.

How Business metrics calculates it

Returning clients ÷ Client base as entered × 100.

The range we use for status labels

On Business metrics, the status band for this KPI is roughly 65 to 100. Higher values are generally healthier in this band. Your niche can sit outside it honestly — the label is a prompt to read the coaching, not a certificate.

Where people fool themselves

Retention that counts a client who bought once three years ago as “active” is a mailing list, not a practice. Define the window (12 months is honest for many shops).
