Methodology
The churn rate is the difference between initial and remaining customers, divided by the initial customer count, then multiplied by 100 to express the result as a percentage.
Formula
Churn Rate = (Initial Customers - Remaining Customers) / Initial Customers × 100%
- Initial Customers: Count at the beginning of the period.
- Remaining Customers: Count at the end of the period.
- Churn Rate: Percentage of customers lost during the period.
Example
Starting with 200 customers and ending with 180 customers gives:
Churn Rate = (200 - 180) / 200 × 100% = 10%
