Customer Churn is talked about as one of the most important metrics for a growing business.  

Customer churn is one of the most important metrics for a growing business to evaluate. While it’s not the happiest measure, it’s a number that can give your company the hard truth about its customer retention.

Customer churn is the percentage of customers that stopped using your company’s product or service during a certain time frame. You can calculate churn rate by dividing the number of customers you lost during that time period — say a quarter — by the number of customers you had at the beginning of that time period.

For example, if you start your quarter with 400 customers and end with 380, your churn rate is 5% because you lost 5% of your customers.

Obviously, your company should aim for a churn rate that is as close to 0% as possible. In order to do this, your company has to be on top of its churn rate at all times and treat it as a top priority.

You may be wondering why it’s necessary to calculate churn rate. Naturally, you’re going to lose some customers here and there, and 5% doesn’t sound too bad, right?

Well, it’s important because it costs more to acquire new customers than it does to retain existing customers. In fact, an increase in customer retention of just 5% can create at least a 25% increase in profit. This is because returning customers will likely spend 67% more on your company’s products and services. As a result, your company can spend less on the operating costs of having to acquire new customers. You don’t need to spend time and money on convincing an existing customer to select your company over competitors because they’ve already made that decision.

Again, it might seem like a 5% churn rate is solid and healthy. You can still make a vast revenue with that churn rate. However, consider the example below when thinking about the impact of your churn rate.
