Churn rate calculator
The most-asked churn question is "did I calculate this right?" This calculator takes the only three numbers you need — starting subscribers, cancellations, and new signups — and returns monthly gross churn with the correct denominator.
Calculate monthly churn
Monthly gross churn
5.00%
60 / 1200 = 5.00%. Ending subscribers: 1,290.
Note: new signups are deliberately excluded from the denominator. Dividing by ending subscribers (start - cancellations + new) artificially lowers the number and hides churn problems.
