What is Customer Retention Rate?
Customer Retention Rate measures the percentage of customers who continue doing business with you over a specific period. It is the inverse of churn rate and is one of the most important metrics for subscription businesses, SaaS companies, and any business with repeat customers.
Increasing retention by just 5% can increase profits by 25-95%, according to Bain & Company. Retained customers also spend 67% more than new customers and are easier to upsell.
Retention Rate Formula
For example, starting with 1,000 customers, ending with 1,100, and adding 300 new customers:
- Retained Customers = 1,100 − 300 = 800
- Retention Rate = 800 ÷ 1,000 × 100 = 80%
- Churn Rate = 100% − 80% = 20%
Retention Rate vs Churn Rate
✅ Retention Rate
The percentage of customers you keep. Higher is better. Directly measures customer satisfaction and loyalty.
❌ Churn Rate
The percentage of customers you lose. Lower is better. Retention Rate = 100% − Churn Rate. They are exact complements.

How to Calculate LTV from Retention Rate
Customer Lifetime Value (LTV) can be estimated from your retention rate and average revenue per user (ARPU):
Where: (1 − Retention Rate) = Churn Rate
If your monthly ARPU is $50 and your monthly retention rate is 95% (5% churn): LTV = $50 × (0.95 ÷ 0.05) = $950.
Strategies to Improve Customer Retention
- Deliver exceptional onboarding: The first 30 days determine long-term retention. Guide users to their first "win" quickly.
- Build a loyalty program: Rewarded customers are 3-5x more likely to stay. Points, exclusive access, and tiered benefits work well.
- Personalize the experience: Use behavioral data to send relevant product recommendations, content, and offers.
- Ask for feedback regularly: NPS surveys and exit interviews help you fix issues before they cause mass churn.
- Create community: Customers who feel part of a brand community have 30%+ higher retention rates.
Frequently Asked Questions
How do I calculate customer retention rate?
Retention Rate = ((End Customers − New Customers) ÷ Start Customers) × 100. For example, starting with 1,000 customers, ending with 1,100, and adding 300 new = (1,100 − 300) ÷ 1,000 × 100 = 80% retention.
What is a good retention rate?
For SaaS, a monthly retention rate of 90-95% is good. For e-commerce, an annual repeat purchase rate of 20-40% is average.
How does retention rate relate to churn rate?
Retention Rate and Churn Rate are complementary. Retention Rate = 100% − Churn Rate. If you have 95% monthly retention, you have 5% monthly churn.
How can I estimate LTV from retention rate?
LTV = ARPU × (Retention Rate ÷ (1 − Retention Rate)). For example, with $50/month ARPU and 95% monthly retention: LTV = $50 × (0.95 ÷ 0.05) = $950.
