What is Churn, Why is it Bad, and Why it Needs to be Fixed?


In the competitive landscape of modern business, understanding and managing customer churn is critical for sustained success. Churn, in its simplest terms, refers to the phenomenon where customers cease their relationship with a company. In this essay I delve into what churn is, why it is detrimental to businesses, and the reasons for addressing and mitigating its effects. These effects are particularly adverse for SaaS (software-as-a-service) businesses.

What is Churn?

Customer churn, also known as customer attrition, is the rate at which customers stop doing business with an entity over a specific period. It is commonly expressed as a percentage of total customers lost within a given timeframe. For example, if a subscription service starts with 1,000 customers and loses 100 over a month, the churn rate for that month is 10%. Churn can be voluntary, where customers actively decide to leave, or involuntary, due to circumstances beyond the customer’s control, such as expired credit cards or geographic relocations.

Why is Churn Bad?

Churn poses significant challenges to businesses for several reasons:

1. Revenue Loss: The most immediate and apparent impact of churn is the loss of revenue. Every departing customer represents lost future income, which can be particularly damaging in subscription-based models where revenue is expected to recur.

2. Customer Acquisition Costs (CAC): Acquiring new customers is typically more expensive than retaining existing ones. Marketing campaigns, promotions, and onboarding processes require substantial investment. High churn rates mean that these investments yield lower returns, as companies must continuously replace lost customers just to maintain their revenue levels.

3. Company survival: If the churn rate is higher than the new customer acquisition rate, the company is slowly decaying. This scenario is unsustainable in the long term because it signifies that the company is losing customers faster than it can attract new ones. The consequences of this imbalance can be severe and include cash flow problems, increased costs, and loss of market share.

4. Negative Brand Perception: High churn rates can signal dissatisfaction among the customer base, which can damage a brand’s reputation. Dissatisfied customers are more likely to share their negative experiences, potentially deterring new customers and compounding the issue.

5. Operational Strain: Constantly addressing churn requires resources that could be better spent on innovation and improvement. High churn necessitates a focus on short-term fixes rather than long-term strategic growth, hindering overall business development.

6. Impact on Valuation: For many businesses, especially startups and companies seeking investment, churn is a critical metric for potential investors. High churn rates can lead to lower valuations as they indicate potential instability and higher risk.

Why Churn Needs to be Fixed

Addressing churn is not just about plugging a revenue leak; it is about fostering sustainable growth and ensuring long-term business health. Here are several reasons why fixing churn is imperative:

1. Enhanced Customer Lifetime Value (CLV): By reducing churn, businesses can increase the average lifetime value of their customers. This means more revenue from each customer over time, leading to a healthier bottom line.

2. Stronger Customer Relationships: Efforts to reduce churn often involve improving customer service, enhancing product offerings, and personalizing customer experiences. These improvements foster stronger, more loyal customer relationships, creating advocates who can drive organic growth through referrals and positive word-of-mouth.

3. Better Competitive Positioning: Companies with lower churn rates typically enjoy stronger market positions. They can invest more in innovation and expansion rather than in replacing lost customers. This strategic advantage allows them to stay ahead of competitors who are bogged down by higher churn rates.

4. Operational Efficiency: Reducing churn can lead to more stable and predictable revenue streams, allowing for more accurate forecasting and efficient resource allocation. Businesses can focus on optimizing and scaling operations rather than constantly firefighting churn-related issues.

5. Improved Employee Morale: High churn can also affect employee morale, especially in customer-facing roles. Constantly dealing with dissatisfied customers can be demoralising. By addressing the root causes of churn, businesses can create a more positive work environment, leading to higher employee satisfaction and retention.


Churn is a critical metric that reflects the health of a business’s customer relationships and overall operational effectiveness. While the adverse effects of churn can be severe, they also underscore the importance of addressing this issue proactively. By understanding the causes of churn and implementing strategies to reduce it, businesses can ensure sustained growth, stronger customer loyalty, and a more robust market position. Fixing churn is not merely a reactive measure but a strategic imperative that underpins long-term success in today’s competitive business environment.
