Calculate customer churn rate and retention metrics to understand your subscriber health.
Understanding Churn Rate
Churn Rate measures the percentage of customers who stop using your product or service during a given period. It is one of the most critical metrics for subscription-based businesses.
Retention Rate is the inverse of churn, the percentage of customers who remain active. Even small improvements in retention can have a significant compounding effect on revenue over time.
Annualised Churn projects your periodic churn rate across a full year using compound calculation. A 5% monthly churn does not equal 60% annual churn, it compounds to approximately 46% annually.
Revenue Churn measures the percentage of recurring revenue lost from existing customers during a period. Unlike customer churn, it weights the financial impact of each lost account.
Net Revenue Retention (NRR) accounts for expansion revenue (upgrades, cross-sells) alongside losses. An NRR above 100% means your existing customers are generating more revenue over time, even after accounting for churn.
Acceptable Rates: SaaS companies typically target less than 5-7% annual churn for SMB customers and under 1.5% for enterprise accounts. If your annualised churn exceeds 10%, it signals a significant retention problem that requires attention. Best-in-class SaaS companies achieve NRR of 120%+.
