Churn Rate Calculator Formula & Method
This tool utilizes standard accounting algorithms to compute business returns:
Customer Retention Rate (%) = 100% - Churn Rate (%)
Where:
- Customers Lost: Cancelled or non-renewed accounts.
- Start Customers: Total active account count at period start.
- Churn Rate (%): Customer attrition percentage.
Worked Example
Example: 25 Customers Lost out of 500 Start Customers
- Customers Lost: 25 clients
- Start Customers: 500 clients
Applying the formula yields:
Customer Churn Rate: (25 / 500) * 100 = 5.00% / month
Retention Rate: 100% - 5.00% = 95.00%
Implied Lifespan: 100 / 5.00 = 20.0 Months
