Frequently Asked Questions
What is a good churn rate?
For SaaS businesses: monthly churn of 3-5% is average, below 2% is good, below 1% is excellent. Annual churn below 10% is considered best-in-class. B2B companies typically have lower churn (3-7% annual) than B2C (5-15% annual). Enterprise SaaS targets below 5% annual.
What is the difference between gross and net churn?
Gross churn only counts lost revenue (cancellations + downgrades). Net churn subtracts expansion revenue (upsells + upgrades) from lost revenue. Net churn can be negative (called 'negative churn'), which is ideal because it means existing customers are growing in value.
What is Net Revenue Retention (NRR)?
NRR measures total revenue retained from existing customers including expansions. NRR = (Start MRR - Lost + Expansion) / Start MRR. 100%+ means the cohort is growing. Top SaaS companies have NRR of 110-140%. NRR above 100% indicates negative net churn.
