Churn Calculation Examples
Example 1: Monthly Churn
January 1: 5,000 customers
January 31: 4,650 customers
New customers acquired: 150
Customers lost: 500
Churn Calculation:
Lost customers: 5,000 + 150 - 4,650 = 500
Churn rate: (500 ÷ 5,000) × 100 = 10%
Example 2: Annual Churn
January 1, 2024: 10,000 customers
December 31, 2024: 6,500 customers
New customers acquired: 2,500
Customers lost: 6,000
Annual Churn:
Lost: 10,000 + 2,500 - 6,500 = 6,000
Churn rate: (6,000 ÷ 10,000) × 100 = 60%
Example 3: Cohort Analysis
January 2024 cohort:
Acquired: 500 customers
Still active after:
- Month 1: 450 (10% churn)
- Month 3: 380 (24% churn)
- Month 6: 310 (38% churn)
- Month 12: 225 (55% churn)
