Do you know what customer churn is? And more importantly, do you understand why it matters for your business?

Customer churn can go from unexpected nuisance to full-blown disaster, depending on the industry. For example, services such as streaming video or subscription-based software require customers to consistently renew their contracts to keep enjoying the service – so a high customer churn rate can quickly become unsustainable.

And here’s the shocking stat: research from SugarCRM shows UK businesses facing an average churn rate of 33%! That means you can expect to lose a third of your customers every year.

This article will help you to identify and stop customer churn.


What is Customer Churn and Why Does It Matter?

Customer churn, also known as customer attrition, is the phenomenon where customers stop using your products or services. Basically, it’s what happens when you realise you have fewer customers than you did before.

Churn could be due to various reasons, such as dissatisfaction, pricing, switching to a competitor, or simply no longer needing your offerings. Identifying and understanding the reasons behind customer churn is crucial, as there are often steps you can take to ensure your customers keep using your services.


The Customer Churn Formula

In order to understand customer churn, you need to calculate your customer retention rate. The customer churn formula measures how many customers have left over a given period of time. It’s expressed as a percentage and is calculated by:


(Number of customers at the start of the period - Number of customers at the end of the period) / Number of customers at the start of the period


For example, if you had 200 subscription customers at the start of a quarter and 165 customers at the end, your customer churn rate would be (200-165)/200 = 17.5%.


Why Does Customer Churn Matter?

But why does customer churn matter so much? The answer lies in its direct impact on your bottom line.

When customers leave, you lose not only their current revenue but also the potential revenue they could have brought in the future. But that’s not all – customer churn can tarnish your reputation and damage your relationship with existing customers.

If customers are constantly signing up and then quickly leaving, it conveys your product or service isn’t up to par. And word can spread quickly, with hungry competitors ready to take advantage of any perceived weakness.

That’s why it’s important to understand the factors influencing customer churn and to implement strategies to reduce or prevent it from happening. A key way to identify and solve customer churn issues? A robust customer churn analysis.


What is Churn Analysis?

The sneaky thing about customer churn is that it often happens quietly. It can be difficult to identify and analyse problems when customers don’t reach out and complain directly. Without a reason to actively examine your customer churn, you may wake up one day to learn customers have been leaving for months or years without your knowledge.


Enter customer churn analysis – a powerful tool allowing you to identify trends in customer churn and determine the impact of potential solutions. But what is churn analysis, and how does it work?


How To Do A Customer Churn Analysis

Customers offer you tons of actionable insights and data every time they interact with your business. To start a customer churn analysis, collect and analyse data from existing customers who have already turned away from your company.

  1. Collect customer data: Start by gathering all the relevant customer information in one place. This typically includes demographic information such as age, gender, location, and purchase history. 
  2. Identify patterns: Look for commonalities in the data that could point to underlying reasons for churn. For example, customers who leave soon after signing up may have been misled by your messaging or pricing model. Or have you noticed that customers from a certain region or demographic are more likely to churn?
  3. Analyse trends: Compare customer data against your overall business performance. Are there any changes in customer behaviour corresponding with shifts in the market or product updates? Using analytics tools, you can pinpoint what happened before and after customers left to uncover potential causes of churn.
  4. Take action: Once you understand why customers are leaving, it’s time to prevent it from happening again. Consider changes in pricing, product updates, or customer outreach tactics to keep your customers engaged and on board for the long term. Knowing how to price your product, which features to prioritise, and when to conduct customer outreach can all help you minimise churn.
  5. Assess effectiveness: You must measure the effectiveness of changes you make to keep your customers. Use analytics tools to track customer activity over time and measure customer retention rates. With this data, you can evaluate how successful your customer churn analysis is and tweak it as needed.


Being Proactive: Identifying High-Risk Customers to Minimise Churn

One of the key steps in effective churn management is identifying high-risk customers. These are the customers who are most likely to churn based on their behavioural patterns, product usage, or engagement with your business.

By identifying them early, you can take proactive measures to minimise churn and retain their loyalty. However many eCommerce companies find they are so busy dealing with the day-to-day operations that they don't have the resources or time to effectively monitor customer activity and detect changes in behaviour.

  • Segmentation: Divide your customer base into segments based on various factors such as purchase history, duration of the relationship, or demographic data. Analyse the churn rates within each segment to identify patterns and outliers.


  • Monitoring customer activity: Keep a close eye on customer behaviour and engagement metrics such as frequency of product usage, number of support tickets raised, or any decline in activity. Sudden changes in these metrics can signal a higher risk of churn.
  • Utilising predictive analytics: Leverage predictive analytics techniques to forecast future churn probabilities for individual customers. By using historical data combined with machine learning algorithms, you can identify customers who are likely to churn before it happens.
  • Keeping in touch: Make sure you reach out to customers periodically to stay top-of-mind and offer relevant discounts or promotions. Real-time monitoring of customer sentiment can help you detect if a customer is unhappy or frustrated with your product/service so you can take corrective actions before it's too late.


Getting Reactive: Using Data to Drive Retention Strategies

Data is at the heart of effective churn management. This is where data-driven applications can help you out. With the right tools, you can drive targeted retention strategies that will keep your customers satisfied and loyal.


  • Predictive modeling: Build predictive models to anticipate churn before it happens. By combining historical customer data with advanced algorithms, you can identify early warning signs and take proactive steps to prevent churn.
  • Personalisation: Use customer data to personalise your marketing messages, product recommendations, and customer experiences. By delivering tailored experiences, you can enhance customer satisfaction and reduce the likelihood of churn.
  • Ongoing monitoring: Continuously monitor customer behaviour and satisfaction metrics to identify any changes or trends. By proactively addressing issues or dissatisfaction, you can prevent customers from churning.
  • Feedback loops: Establish feedback channels to gather insights from your customers regularly. Actively listen to their needs, concerns, and suggestions, and use this information to continuously improve your offerings and customer experience.



In a competitive business landscape, customer churn is a pervasive threat that can erode profits and damage your reputation. Understanding its impact and employing proactive strategies are essential for long-term success. By embracing customer churn analysis, identifying high-risk customers, and leveraging data-driven techniques, you can effectively reduce churn rates and foster customer loyalty. This holistic approach ensures not only the retention of valuable clients but also strengthens your market position. Commit to these insights and strategies to minimize customer churn, safeguard your revenue, and establish a resilient and thriving business.
