Frequently Asked Questions
What's a good monthly churn rate for SaaS?
For B2B SaaS, under 2% monthly (or under 5% annual) is considered healthy. Enterprise products aim for under 1% monthly. B2C/freemium naturally have higher churn (5-10% monthly).
What's the difference between customer churn and revenue churn?
Customer churn counts accounts lost. Revenue churn measures MRR lost. They can differ significantly — losing many small accounts vs. one large enterprise account produces very different revenue impacts.
How does negative churn work?
Negative churn occurs when expansion revenue from existing customers (upgrades, add-ons) exceeds the revenue lost from churned customers. It's the holy grail of SaaS — your revenue grows even without new customers.
How do I reduce SaaS churn?
Focus on: strong onboarding (first 90 days are critical), proactive customer success outreach, usage monitoring to identify at-risk accounts, regular product improvements, and making cancellation harder through deep integrations.
Why does even a small churn improvement matter so much?
Churn compounds! Reducing monthly churn from 5% to 3% means retaining 69% vs 54% of customers annually. Over 3 years, that's 33% vs 16% retention — a 2x difference from just 2% monthly improvement.
Should I track gross churn or net churn?
Both. Gross churn shows how many customers/revenue you're losing (your retention problem). Net churn factors in expansion revenue (your overall growth picture). A company can have high gross churn but negative net churn through upselling.
