Formula
Churn rate = customers lost ÷ customers at the start of the period. Retention rate is simply 100% minus churn.
How it works
Small changes in churn compound enormously. Cutting monthly churn from 5% to 3% can lift the average customer lifespan from 20 to over 33 months — raising lifetime value by more than half without acquiring a single new customer.
Frequently asked questions
What is a good churn rate?⌄
It varies by business, but many subscription companies aim for monthly churn below 3–5%. Lower is better; annual churn under 5–7% is considered strong.
How does churn affect lifetime value?⌄
Average customer lifespan is roughly 1 ÷ churn rate. Lower churn means longer lifespans and higher lifetime value for the same acquisition cost.
What's the difference between customer and revenue churn?⌄
Customer churn counts lost accounts; revenue churn counts lost dollars. Revenue churn can differ when you lose large or small accounts, or when customers downgrade.
Sources & methodology
