Understanding Churn
Churn rate measures the percentage of customers who stop using your service. It's calculated as:
Churn Rate = (Customers Lost / Customers at Start) × 100Frequently Asked Questions
What is a good churn rate?
For B2B SaaS, monthly churn under 3% is good, under 2% is excellent. B2C typically has higher churn (5-7%). Context matters - early-stage startups often have higher churn than mature companies.
What is Net Revenue Retention (NRR)?
NRR measures revenue retention including expansion. NRR > 100% means expansion revenue (upsells, cross-sells) exceeds lost revenue from churn. This is the gold standard for SaaS companies.
How can I reduce churn?
Focus on customer success, improve onboarding, provide excellent support, regularly gather feedback, identify at-risk customers early, and ensure your product delivers continuous value.
Why does churn matter?
High churn makes growth expensive and unsustainable. If you lose customers as fast as you acquire them, growth stalls. Reducing churn is often more cost-effective than acquiring new customers.
