What is Churn Rate?
Churn rate measures the percentage of customers who stop using your product or service within a given period. It is one of the most important metrics for SaaS, subscription companies, and any recurring-revenue business because it shows how well you retain customers. A high churn rate signals customer dissatisfaction or product gaps, while a low churn rate indicates strong retention and market fit.
Our Churn Rate Calculator simplifies this calculation by converting your starting customers and lost customers into a precise churn percentage. Tracking churn rate consistently gives you a clear picture of customer health, helps identify retention issues early, and shows how customer behavior influences revenue stability.
Why Churn Rate is Important for SaaS and Subscription Businesses?
Churn directly affects growth, revenue predictability, and customer lifetime value. Even small increases in churn can significantly impact ARR and overall business momentum. That is why SaaS companies monitor churn closely to understand whether their product experience, onboarding, support, and pricing strategies are working.
Using a Churn Rate Calculator ensures your measurement stays consistent and accurate. It helps you spot trends, evaluate retention efforts, and determine how much new acquisition is needed just to maintain growth. Low churn strengthens profitability, improves forecasting, and provides a solid foundation for scaling.

FAQs on Churn Rate
How is churn rate calculated?
Churn rate is calculated by dividing the number of customers lost during the period by the number of customers at the beginning, then multiplying by 100.
What is a good churn rate?
It depends on the industry. SaaS companies often target monthly churn below 3% and annual churn below 10%, though expectations vary by business model.
Does churn rate include new customers?
No. Churn focuses only on the customers you lost, not new customers gained during the period.
Should I track churn monthly or annually?
Most SaaS teams track monthly churn for accuracy and annual churn for long-term planning.
Can churn rate affect LTV?
Yes. Higher churn reduces lifetime value because customers stay for shorter periods.
Does churn help identify product issues?
Absolutely. Rising churn often highlights problems with onboarding, product adoption, support quality, or pricing.
