Subscriber churn rate calculator

Worked example

• Subscribers at start: 1,000
• Starting subscribers lost: 40

Starting cohort churn · 4%

How to interpret the result

Count losses from the starting cohort. Include the same cancellation policy and time window in both periods.

Publisher example

A starting group of 600 loses 30 paid members, so churn is 5%. Adding 100 subscribers during the month changes net growth but leaves starting cohort churn at 5%.
