What Is Churn Rate? Learn and Calculate with Our Churn Rate Calculator.

Churn rate is the percentage of subscribers who cancel their subscriptions over a specific time period. High churn undermines growth, while lower churn supports stronger long-term LTV and profitability. By using a Churn Rate Calculator, you can easily measure and track your churn rate, helping you identify trends and take proactive steps to reduce subscriber loss. This tool provides valuable insights, enabling you to improve retention strategies and boost overall business performance.

Churn Rate

Example : Calculating Churn Rate for a Coffee Subscription Brand

Over the past 30 days, Sara reviewed her store's subscription data:

She started the month with 400 active subscribers
By the end of the month, 360 subscribers remained
This means 40 customers canceled their subscriptions during that period

To calculate churn rate, Sara divides the number of lost subscribers by the number at the beginning of the period:

40 ÷ 400 = 0.01 or 10% churn rate

That means Sara is losing 10% of her subscribers every month.
At that rate, she could lose nearly half of her subscriber base in just 5 months, if churn isn’t addressed.
By tracking churn regularly with Churn Rate Calculator, she can catch issues early and take action to retain more customers.
