Frequently Asked Questions

How is churn rate calculated?

Churn Rate = (Customers Lost ÷ Customers at Start of Period) × 100. If you started with 1000 customers and lost 50, churn = (50 ÷ 1000) × 100 = 5% monthly churn.

What is an acceptable churn rate?

SaaS businesses target 3-5% monthly churn (15-20% annually). Enterprise software aims for <1% monthly. Consumer subscriptions may see 5-7% monthly. Industry and business model matter greatly.

What is the difference between voluntary and involuntary churn?

Voluntary churn: customers actively cancel. Involuntary churn: failed payments, expired cards. Involuntary churn (often 20-40% of total) can be reduced through payment retry and card updater services.

How does churn affect business growth?

At 5% monthly churn, you lose about 46% of customers yearly. To grow, new acquisitions must exceed churn. Reducing churn often provides better ROI than increasing acquisition.

What is negative churn?

Negative churn occurs when expansion revenue from existing customers (upgrades, add-ons) exceeds lost revenue from churned customers. It's a powerful growth driver that compounds over time.
