Frequently asked questions
- What is a good monthly churn rate?
- For SaaS, monthly churn below 2% is considered good; below 1% is excellent. Annual equivalents: 2% monthly ≈ 21% annual churn. Enterprise software tends to have lower churn (0.5–1%/mo) than SMB-focused products (2–5%/mo).
- What is the difference between customer churn and revenue churn?
- Customer churn counts the number of accounts lost. Revenue churn (MRR churn) measures the dollar value lost. Revenue churn can be negative (net negative churn) if expansion revenue from existing customers exceeds cancellations — a sign of a very healthy business.
- How does churn relate to customer lifespan?
- Average customer lifespan ≈ 1 ÷ monthly churn rate. At 10% monthly churn, average lifespan is 10 months. Use this to estimate LTV.
