The proportion of consumers that continue to pay for a product after a certain period of time is referred to as the retention rate. This is an important success statistic for subscription-based businesses, such as SaaS software providers, and firms whose consumers purchase the same items from them on a regular basis. It makes a lot of natural sense to keep your current consumers using your product. To summarise, having a high retention rate is a very efficient and advantageous strategy to build the firm. Measuring your client retention rate enables you to measure your performance and find and correct areas for development.
