Behind the numbers

What is Churn?

The formula

Churn rate is typically calculated by dividing the number of customers lost during a specific time period by the total number of customers at the beginning of that period. For example, if a company starts a quarter with 100 customers and loses 5 of them by the end of that quarter, the churn rate is 5/100 or 5%.
