A 5.0% monthly churn rate is within the typical SaaS range (3–8%). Reducing it by even 1% could significantly increase customer lifetime value.

How to calculate churn rate

Churn rate: Customers lost during the period divided by customers at the start of the period, multiplied by 100. If you lost 25 out of 500 customers in a month, your monthly churn rate is 5%.

Annualised churn: For monthly periods, we use the compound formula: 1 − (1 − monthly rate)^12. This accounts for the compounding effect and gives a more accurate annual projection than simply multiplying by 12.

Benchmarks: Most SaaS businesses see monthly churn rates between 3–8%. Best-in-class companies aim for under 3%. A significant portion of churn is involuntary, caused by failed payments rather than active cancellations, and is recoverable through dunning. Understanding the difference between involuntary and voluntary churn helps you target the right fix.

Looking for attrition rate instead? The formula is the same. Try our attrition rate calculator.
