Percentage of original customers retained across the period
How to Use This Calculator

Frequently Asked Questions
Why must new customers be subtracted in the CRR formula?↓
If new customers were not subtracted, strong sales acquisition would mask heavy customer cancellations. The standard formula strictly isolates how many original customers continued doing business.
What is a strong annual Customer Retention Rate benchmark?↓
For B2B software and professional services, annual CRR of 90% or higher is considered excellent. For retail e-commerce, repeat customer retention rates typically range between 25% and 40%.
How does improving retention by 5% dramatically increase corporate profits?↓
Bain & Company research demonstrates that increasing customer retention rates by just 5% increases profits by 25% to 95% because retaining customers eliminates expensive acquisition costs.
What strategies are most effective at boosting customer retention?↓
Effective retention strategies include structured customer onboarding, responsive support ticketing, proactive check-ins based on product usage drops, and loyalty rewards.
