What it calculates
Churn rate is the percentage of customers who leave during a period. It is the leak that silently cancels out your acquisition efforts.
Formula & methodology
Churn Rate = (Customers Lost ÷ Customers at Start) × 100
Example
Losing 40 of 800 customers in a quarter is a 5% churn rate.
