Frequently Asked Questions
Why is client retention more cost-effective than acquisition?
Acquiring a new client costs 5-7x more than retaining an existing one. Retained clients also spend 67% more on average and are 50% more likely to try new services, making retention the highest-ROI growth strategy for service businesses.
What's a good client retention rate for service businesses?
Top-performing service businesses maintain retention rates of 80-90%. The industry average is around 60-70%. Even a 5% improvement in retention can boost profits by 25-95% due to compounding lifetime value.
How does lifetime value factor into retention calculations?
Lifetime value (LTV) accounts for total revenue a client generates over their entire relationship, including repeat visits, upsells, and referrals. Our calculator uses LTV to show the true cost of each lost client, not just the value of a single appointment.
What tools help improve client retention?
Automated rebooking reminders, personalized follow-ups, loyalty programs, and consistent communication are the top retention drivers. Scheduling software with built-in reminders typically improves rebooking rates by 25-40%.
Our Methodology
Retention ROI is modeled using client lifetime value, churn rates, and acquisition costs. We calculate the revenue difference between retaining existing clients versus replacing them with new ones, factoring in higher spending from loyal customers, referral value, and the compounding effect of even small retention improvements.

“I was spending all my marketing budget on new clients while my existing ones quietly disappeared. This calculator showed me that keeping 10 more clients per month was worth more than 50 new leads.”
