Churn Rate
No one likes to talk about customers leaving. But in the world of subscription-based businesses, it can’t be ignored, and that’s where churn rate comes in. At its simplest, churn rate is the percentage of customers who stop using your product or service over a given time period. It’s a key health check, letting you know if your business is holding on to its users or if people are slipping through the cracks.
Churn rate matters because keeping an existing customer tends to be far more cost-effective than acquiring a new one. A high churn rate can suggest something isn’t quite right: your product may not meet users’ needs, onboarding is too tricky, or competitors are luring your customers away. On the other hand, a low churn rate is a healthy sign that people are finding value and sticking around.
There are a few ways to slice churn. Customer churn is about the number of users leaving; revenue churn looks at the money lost when subscribers downgrade or cancel. Understanding churn rate helps you:
- Improve product experience and customer support
- Spot early signs of customer dissatisfaction
- Align teams around reducing avoidable losses
- Forecast future revenue more accurately
- Balance your growth strategy with long-term sustainability
