# Churn

From Displayr

Proportion of customers of a firm to switch to another firm. For example, if in a year 7% of a company's customers switched to a competitor, then the churn is 7%.

There is no standard formula for computing churn. Different formulas adjust for things like:

- The amount of revenue obtained from customers (
*weighted churn*). - Excluding customers from the calculation if they left the category.
- Treatment of customers that left and returned.

## Also known as

- Churn out.
- Defection rate.
