Enter values to calculate.

Churn rate is the percentage of customers who stop using your product over a set period. The formula is simple: customers lost ÷ customers at the start of the period × 100.

Track it as a trend, not a one-off number. A rising churn rate quietly cancels out new signups, so catching it early matters.

The calculator tells you the what; closing the loop tells you the why. Collect cancellation reasons and product feedback in Feedjolt to fix the causes behind your churn.
