Churn Rate Example

How to calculate churn rate?

  1. First, determine the total number of users at the beginning or the period.

    For this example, we will say that our company had 200 total customers.

  2. Next, determine the number of lost customers through the period.

    After a period of 1 month, 20 customers are lost.

  3. Finally, calculate the churn rate.

    Using the formula we find the churn rate to be 20 / 200 * 100 = 20%.
