❓ FAQs

3. Should I track churn monthly or yearly?
Track monthly for agility, yearly for trends. Most SaaS companies use monthly churn.
4. What’s the difference between customer churn and revenue churn?
- Customer churn = number of customers lost.
- Revenue churn = percentage of recurring revenue lost.
5. How does churn affect growth?
High churn forces you to spend more on acquiring new customers just to maintain the same revenue level.
6. Is churn rate only for SaaS?
No. It’s also critical for gyms, mobile apps, media subscriptions, and B2B services.
7. Can churn rate be negative?
Not typically. But if you're calculating net churn, it's possible to have negative churn when expansion revenue offsets lost revenue.
8. What is gross churn?
The total loss in customers or revenue, not accounting for any new or expanded revenue.
9. How does churn impact CAC?
High churn increases your Customer Acquisition Cost (CAC) because you'll need to acquire more customers to replace the lost ones.
