Start for freeUser Churn Rate is the percentage of users who stop using a product or service over a specific period of time. It measures how many users leave or become inactive, helping businesses understand user retention and loss.
Synonyms: User Attrition Rate, Customer Churn Rate, User Turnover Rate, User Loss Rate

User Churn Rate is a critical metric for businesses to track because it directly impacts growth and revenue. High churn means losing users faster than gaining new ones, which can signal problems with user satisfaction, product value, or competition.
Businesses use User Churn Rate to identify trends in user behavior, evaluate the effectiveness of retention strategies, and improve customer experience. It helps prioritize product improvements and marketing efforts to reduce churn.
If a mobile app has 1,000 active users at the start of the month and 100 users stop using it by the end of the month, the User Churn Rate is 10%. Tracking this over time shows whether user retention is improving or declining.
