Churn Rate Calculator
Calculate churn rate, retention rate, and retained customers using your starting customer count and lost customers during a period. This is useful for SaaS, subscriptions, ecommerce, and customer analytics.
Enter the number of customers at the start of the period.
Enter the number of customers lost during the period.
How This Calculator Works
This calculator divides lost customers by starting customers to estimate churn rate for a given period. It also calculates retention rate and the number of customers retained.
Formula
Churn Rate = (Lost Customers / Starting Customers) * 100
Example
If you start the month with 1,000 customers and lose 75, the churn rate is 7.5%. That means your retention rate is 92.5% and you retained 925 customers.
