Frequently Asked Questions

How do you calculate churn rate?

Churn rate = (Customers lost during period / Customers at the start of the period) x 100.

How do I convert monthly churn to annual churn?

Annual churn = 100 x (1 - (1 - monthly churn rate)^12), since customers who churn each month compound over the year rather than adding up linearly.

What is a good churn rate?

For subscription businesses, monthly churn under 3-5% is often considered healthy, though acceptable rates vary significantly by industry and customer segment.
