How the calculation works
Churn rate = users lost during the period ÷ users at the start × 100
Example
Losing 75 of 1,500 starting subscribers produces a 5% churn rate.
Why this result matters
Churn quantifies audience loss and can help forecast the replacement growth needed to keep a community or subscription base stable.
Tips for a more useful estimate
- Choose one time period and definition.
- Do not count new users in the starting base.
- Analyze voluntary and payment-failure churn separately.
Frequently asked questions
Is churn the opposite of retention?
