Frequently Asked Questions
What's a good churn rate?
It depends on your industry. For B2B SaaS, aim for <5% annually (<0.5% monthly). For B2C, <10% annually is good.
Should I include new customers in churn calculations?
No. Use customers at the start of the period as your denominator to get a more accurate picture of retention.
How does churn affect growth?
High churn is like a leaky bucket—you need to acquire more customers just to maintain your current size.
What is Churn Rate?
Churn rate (also called attrition rate) is the percentage of customers who stop using your product or service during a given time period. It's one of the most critical metrics for subscription businesses and any company focused on customer retention.
