About Churn Rate Calculator
Monthly vs annual churn
A 5% monthly churn compounds to about 46% annual churn (1 − 0.95¹² = 0.46). Small monthly numbers can hide huge yearly losses. Always report both.
Benchmarks
Consumer SaaS (B2C): 3-7% monthly is typical. Enterprise SaaS: under 1% monthly is excellent, 1-2% normal, 3%+ concerning. Net negative churn (expansion exceeds losses) is the holy grail.
Revenue vs customer churn
Customer churn counts heads. Revenue churn weights by spend — a single big customer leaving can dwarf many small ones. Always track both; the gap tells you about your customer mix.
