FAQ

What's a good churn rate?

For B2B SaaS, 2-3% monthly (or under 5% annual) is excellent. B2C and SMB typically see higher churn.

Should I focus on customer or revenue churn?

Revenue churn is often more important. Losing a $10K customer matters more than losing a $100 customer.

How can I reduce churn?

Improve onboarding, increase engagement, provide proactive support, and identify at-risk customers early.
