Churn Rate is the percentage of customers lost over a specified time. It measures customer retention and business health.

​
Calculating Churn Rate

If 100 customers start the year and 50 remain at the end, ChurnRate = (100−50)/100 = 50% Churn rate can be calculated for any period but is usually annualised. Multiply monthly churn by 12 or daily churn by 365 to estimate yearly rates. Longer periods and more data generally increase accuracy.

​
Variability

Churn varies across customer segments, products, and acquisition sources. Upmind provides both short-term and long-term churn rates to help identify retention trends.
