What is Retention Rate? Examples for Retention Rate

Retention Rate is a key performance indicator in analytics that quantifies the proportion of users who continue to engage with a product, service, or website over a given timeframe. It helps businesses understand user loyalty, satisfaction, and the effectiveness of their engagement strategies. A high retention rate typically correlates with strong user experience and product-market fit, whereas a declining rate can indicate issues that may lead to churn. This metric is usually expressed as a percentage and can be calculated for various periods (e.g., daily, weekly, monthly). Tracking retention rate enables data-driven decisions around marketing, product development, and customer success initiatives, ultimately driving sustainable growth.
