Churn Rate

CEO CFO VP Sales CMO VP Product

Churn Rate measures the percentage of customers or revenue lost in a given period due to cancellations, non-renewals, or downgrades. Customer churn rate tracks the number of customers lost; revenue churn (gross revenue retention) tracks the MRR lost. Churn is the primary drain on recurring revenue growth and one of the most critical metrics for SaaS sustainability.

Even small differences in monthly churn compound dramatically over time: a company with 2% monthly churn retains only 78% of customers annually, while one with 1% monthly churn retains 89%.

Common Questions About Churn Rate

What is the difference between customer churn and revenue churn?

Customer churn measures the percentage of customers who cancel. Revenue churn (gross revenue churn) measures the percentage of MRR lost from those cancellations and downgrades. A business with mostly small customers may have high customer churn but low revenue churn if the churned accounts are disproportionately small. Enterprise-focused businesses often focus more on revenue churn because losing one large account has more impact than losing many small ones.

What causes involuntary churn and how do I reduce it?

Involuntary churn occurs when subscriptions lapse due to failed payment: expired cards, insufficient funds, or bank declines. It typically represents 20%–40% of total churn. Reduce it with smart dunning: automated retry logic that times retries based on card network patterns, in-app and email prompts for customers to update payment methods before expiration, and account updater services that automatically refresh card details with issuing banks.

How do I identify customers at risk of churning?

Build a customer health score that combines product usage signals (login frequency, feature adoption depth, seat utilization), support ticket volume and sentiment, NPS score, and contract renewal timeline. Accounts with low usage, recent negative support interactions, or low NPS that are approaching renewal are highest risk. Deploy proactive CS outreach triggered by health score deterioration.

What is negative churn and why is it valuable?

Negative churn occurs when expansion revenue from existing customers exceeds revenue lost to churn, resulting in net revenue growth from the existing base even without new customers. Negative churn is achieved when NRR exceeds 100%. It is extraordinarily valuable because it means the existing customer base is a compounding asset, and the company grows even if new sales temporarily stall.
