Get churn rate, retention, average customer lifetime, and a simple LTV — with the retention curve. The short answer Churn rate = customers lost ÷ customers at the start. Losing 6 of 200 is **3% monthly churn** (97% retention) — about **33 months** of average lifetime and **$2,667** LTV at $80/mo. Customers at start of period Customers churned in period ARPA / mo (for LTV) Lifetime ≈ 1 ÷ churn; LTV ≈ ARPA ÷ churn. A simple model — gross revenue churn and expansion change the full picture.

Retention is the floor everything else stands on. **Churn has an address.** When churn links to the accounts and the support themes behind it, you fix causes — not a percentage on a slide. **Revenue-weighted, not logo-counted.** Losing one large account hurts more than ten tiny ones. Churn beside revenue shows which losses actually matter. FAQ ### Churn & retention questions **How do I calculate customer churn rate?** Customer churn rate = customers lost in a period ÷ customers at the start of that period. For example, losing 6 of 200 customers in a month is a 3% monthly churn rate (97% retention). **How does churn rate relate to customer lifetime and LTV?** Average customer lifetime ≈ 1 ÷ churn rate. At 3% monthly churn that is about 33 months. Multiply by ARPA for a simple LTV — at $80/mo that is roughly $2,667. **What is a good churn rate for SaaS?** For SMB-focused SaaS, 3–5% monthly logo churn is common; the best products, and enterprise-focused ones, run well below 1% monthly. Lower churn compounds — small improvements in retention have an outsized effect on LTV and growth. **Why does churn matter more than it looks?** Churn is a leak under your growth. You can add MRR all year and still stall if it drains out the bottom. Tying churn to the customers and feedback behind it — not just a percentage — is how you fix the cause, not the symptom.
