How to use this calculator
Enter the number of customers, subscribers, or accounts you started with and how many were lost during the period. The calculator turns those numbers into a churn rate percentage.
What the result means
Treat the result as a retention signal, not the whole story. Churn can change because of pricing, onboarding, product quality, support, seasonality, competition, or the type of customer acquired.
Useful next checks
After calculating churn rate, compare it with conversion rate, ROI, break-even point, and the cost of replacing lost customers.
