Frequently Asked Questions
How is churn rate calculated?
Churn rate = (Customers lost ÷ Customers at start) × 100. If you started with 1,000 customers and lost 50 in one month, churn is 5%.
What is a good churn rate?
For SaaS, monthly churn below 5% is common; elite companies target under 2%. Consumer apps may see higher churn. Track trends and compare within your industry.
How does churn affect customer lifetime value?
Higher churn shortens customer lifetimes and lowers LTV. Use the Customer Lifetime Value Calculator to see the revenue impact.
Should I use monthly or annual churn?
Monthly churn is standard for subscription businesses. Enter the period in months — use 12 for annual churn. Consistency matters more than the time frame you choose.
