What is Customer Churn? Why You Should Analyze Customer Churn

Analyze Customer Churn

Customer loss isn’t a fun topic. It takes lots of effort, money, and time to gain customers. So, losing them is always a blow to the ego. Stats consistently show that it costs up to five times more to get a new customer than it does to keep one.

Yet, so many companies focus on customer acquisition instead of retention. In fact, only 18% of companies in the United States value retention over acquisition. 

What does all of this have to do with churn? The answer is simple. To get a handle on customer retention, you must understand and analyze customer churn. 

Let’s talk a bit about customer churn. We’ll look at what it is, how it’s useful, and why you should be analyzing it. 

What is Customer Churn? 

If you don’t know what churn is, it’s simply a number or percentage that represents the total number of customers who stop doing business with you over a given period. They either stop buying products, end their regular subscription, or otherwise quit their relationship with you.

These are customers whose business you had earned, but couldn’t keep. It isn’t a metric that most people like to discuss, but unfortunately, it’s a critical one. 

There are several different methods for calculating churn. The most popular methodology lies in finding the percentage of customers lost over a given time frame.

For example, if you began with 200 customers at the beginning of the year and ended with 150 customers at the end of the year, you would have a churn percentage of 25%. That means that you lost 25% of your customers in that year. 

You can also look at customer churn as a flat number. Using the example above, your churn rate would be 50, because you lost 50 customers.

Additionally, some companies like to look at the total value lost instead. This enables them to stay laser-focused on the actual ramifications and profit consequences of customer churn. 

Why Customer Churn is Important

Regardless of how you calculate, customer churn is a necessary and often painful metric. So, if it’s not fun to calculate, why do it, right? Wrong.

In the U.S. alone, businesses lose about $83 billion each year thanks to customer churn. (That’s billion, with a “b.”) 

Additionally, in study after study, customer loyalty and customer retention remain vital factors for maintaining and increasing profitability. 

If you aren’t calculating churn, then you’re choosing blissful ignorance over actionable change. Avoiding the calculations won’t diminish the loss of customers. Instead, it just eliminates your option to make a difference. However, knowing the number isn’t enough.
