Customer Acquisition Cost (CAC)

Churn rate is a metric used to measure the rate at which customers stop doing business with a company. It is often expressed as a percentage of the total number of customers at the beginning of a period (such as a month or quarter) compared to the number of customers who left during that period. A high churn rate can indicate that a company is losing customers at an alarming rate and may need to take action to improve customer retention.
