📐 Formulas
- Churn Rate—Churn = 100 × Lost / Start
- Retention Rate—Retention = 100 - Churn
- Ending Customers—End = Start - Lost + New
💡 Example
If you start with 1,000 customers and lose 30 during the period:
Churn = 100 × 30 / 1000 = 3%
Retention = 100 - 3 = 97%.
Real-life examples
Example 1: Small SaaS Startup

Example 2: Established SaaS Company
An established company starts with 2,000 customers and loses 60. Churn Rate = 100 × 60 / 2000 = 3%.
