C Letter # Churn Rate **Churn Rate** is an important customer metric that shows the percentage of customers a business loses within a specific period. It is calculated based on customers who stop purchasing a product, using a service, continuing a subscription or maintaining an active relationship with the brand. Churn rate is especially critical for subscription- based companies, SaaS businesses, telecom, finance, e-commerce and digital platforms. Measuring churn rate is important not only to see how many customers leave, but also to understand why they leave. Customers may move away from a brand due to price increases, poor product experience, insufficient support, competitor offers, changing needs, low usage frequency or unmet expectations. If these reasons are not analysed properly, customer loss may increase over time and negatively affect revenue, growth and profitability. Churn rate is usually calculated by dividing the number of customers lost during a specific period by the total number of customers at the beginning of that period. The basic formula is: **Churn Rate = Number of Customers Lost During the Period / Number of Customers at the Start of the Period x 100**. For example, if a company has 100 customers at the beginning of a quarter and loses 20 customers during that period, the churn rate is 20 / 100 x 100 = 20%. This rate can be calculated monthly, quarterly or annually. However, the customer definition used in churn calculations should be clear. For some businesses, customer loss means subscription cancellation, while for others it may mean no purchase within a certain period or the end of active usage. For example, in a SaaS company, cancellation of a subscription is considered churn, while in an e-commerce brand, customers who have not purchased in the last 6 or 12 months may be considered churned customers. Therefore, the churn metric should be defined according to the business model and customer lifecycle. A low churn rate is generally a positive signal. It may indicate that customers are satisfied with the product, service or brand experience and are likely to continue the relationship. However, reducing churn rate to absolute 0% is not always realistic. Some customer loss may be natural, such as the end of a customer's need, budget changes, relocation or the product no longer being relevant. The important goal is to identify and reduce preventable causes of churn. Churn rate should be evaluated together with customer retention rate. Customer retention rate shows how many existing customers are retained, while churn rate shows the percentage of customers lost. These two metrics complement each other in understanding customer loyalty and sustainable revenue. Churn rate becomes more meaningful when analysed together with customer lifetime value, customer acquisition cost, repeat purchase rate, satisfaction scores and support requests. One of the most common reasons for customer churn is that the product or service does not meet customer expectations. Selling to the wrong target audience, weak onboarding, insufficient product usage or the customer not seeing the expected value can increase churn risk. In subscription-based business models, cancellation reasons, usage frequency, payment issues and support records should be reviewed regularly. These analyses help identify which customer segments have a higher risk of leaving. Competitor influence is also an important factor in customer churn. Customers may switch to competing products or services because of better pricing, stronger features, better support, easier usage or stronger brand perception. For this reason, churn analysis should not be limited to internal company [data](https://kriko.io/services/data-analysis-insight); market conditions, pricing strategy, competitor innovations and changes in customer expectations should also be monitored. Understanding why customers leave provides valuable insights for improving pricing, product development, communication and loyalty strategies. In summary, **Churn Rate** is a strategic metric that shows the percentage of customers a company loses within a specific period. When calculated correctly, it provides important insights into customer loyalty, revenue sustainability and product-market fit. To reduce churn, customer feedback should be analysed, risky segments should be identified, product usage should be monitored, support processes should be improved and the value that keeps customers with the brand should be communicated clearly. ## Discover it in the dictionary ### Schema (schema.org) Schema is a structured data markup system, commonly used through the schema.org vocabulary, that helps search engines better understand the content on web pages.… ### Simple Mail Transfer Protocol (SMTP) SMTP, short for Simple Mail Transfer Protocol, is an application-layer protocol used to send emails and transfer them between mail servers.
