Churn Rate


Churn rate, also known as attrition rate, is a business metric that calculates the number of customers who leave a product over a given period of time, divided by the remaining number of customers. It is a measure of customer or employee retention and turnover. Essentially, it determines the percentage of users who have stopped using a company’s product or service within a particular period.


The phonetic spelling of “Churn Rate” is: “churn reit”

Key Takeaways

  1. Definition: Churn Rate, also known as attrition rate, refers to the rate at which customers stop doing business with a company during a certain time period. It’s a vital business metric, especially for those with subscription-based models.
  2. Implication: A high churn rate could indicate customer dissatisfaction, cheaper and/or better offers from competitors, unsuccessful customer onboarding, or a mismatch between the product or services and customer expectations. It’s important to identify and analyze reasons behind the churn to improve customer retention.
  3. Reduction Strategies: To lower the churn rate, businesses need to focus on improving the customer experience, maintaining effective communication, and providing continual value to their customers. This might include implementing customer feedback, improving customer service, offering competitive pricing or loyalty programs.


Churn rate, in the realm of business and finance, represents the percentage of customers or subscribers who discontinue using a product or service during a given time period. It’s extremely important as it reflects customer dissatisfaction, competitive pressures, the impact of price changes, or the success/failure of customer service initiatives. High churn rates can imply that a company is not maintaining its customer base well, negatively affecting its customer lifetime value and potentially its revenues. Conversely, a low churn rate indicates high customer retention, signifying happy customers and successful customer relationship strategies. Thus, monitoring churn rates is essential for businesses to understand their market performance, maintain profitability, and strategize future action plans.


The purpose of calculating the Churn Rate is mainly to understand the rate at which customers stop doing business with an entity over a specific period of time. This metric is particularly important in determining a company’s customer retention and is widely used across numerous industries, such as e-commerce, telecommunications, banking, and subscription-based businesses. By monitoring churn rate, businesses can acquire insights into customer behavior, identify potential reasons for customer loss, and strategize appropriately to increase customer retention.Churn Rate serves as a key performance indicator (KPI) in evaluating a company’s customer satisfaction and product/service value. A high churn rate may indicate dissatisfaction with a company’s products, services, customer service, or prices, while a low churn rate could signify customer loyalty. Therefore, businesses use this measurement to identify areas that require improvement and boost customer retention strategies. In the longer term, managing and reducing churn rate can lead to improved customer loyalty, increased revenue, and enhanced sustainability for a business.


1. Telecommunication Industry: In this industry, the churn rate represents the rate customers stop using a particular telecom service. For instance, if AT&T has a churn rate of 2% per month, it would mean that on average, 2% of AT&T’s total subscribers stop using their services every month.2. Streaming Services: Streaming platforms like Netflix, Hulu, or Disney+ track their churn rate to evaluate customer retention and satisfaction. For instance, if Netflix had a churn rate of 5% annually, it would mean that Netflix loses 5% of its subscriber base over the course of a year. High churn rates might indicate competitive pressures or customer dissatisfaction, prompting these businesses to reassess their strategies.3. Subscription Box Services: Businesses like Blue Apron or Birchbox, which offer subscription-based products, often experience churn when customers decide to cancel their subscriptions. For example, if Blue Apron has a monthly churn rate of 3%, it indicates that every month they lose 3% of their subscribers. They then use this data to strategize ways to retain existing customers and attract new ones.
