Customer retention 101

Updated: Nov 16


TL;DR Customer retention starts with delivering an excellent customer experience.


What comes to mind when you see, hear and say the word ‘retention’? For some, it could mean a businesses’ efforts to ensure their top talent doesn’t quit their jobs, or on the other side of the coin—the customers.


Keeping your existing customers is more profitable, cheaper, and easier than gaining a new customer. So let’s see how you can add value to your business using different customer retention strategies focused on improving customer experience.


What is customer retention?


Is customer retention a relationship? A strategy? A performance metric? No matter what you’ve heard and how you want to define it, retention matters to your role and business because it’s all about making sure customers continue purchasing your company’s product or service.


Customer retention defined


Customer retention refers to the actions undertaken by a business to keep its existing customers satisfied, and loyal, over time. Businesses across many different industries use customer retention as a customer service metric, and it can also be at the core of any business strategy.


Although there is some strategic overlap, customer retention and customer acquisition are not one and the same. Whereas customer acquisition is transactional, customer retention focuses on relationships with customers. In other words, customer retention builds long term trust and loyalty.


Why is customer retention important for business? Customer retention is essential for companies during all stages of growth. When it comes to a healthy business, customer retention is a key player.


  • Lower cost compared to acquiring new customers: Acquiring a new customer can be anywhere from five to 25 times more expensive than selling to existing customers. And you don’t need to put in as much effort into sales, and marketing since they’re already in your net. It’s less about convincing, and more about nurturing the relationship.

  • Increased profits: Providing quality customer service. Increasing customer retention by 5% can increase profits anywhere from 25% to 95% and existing customers provide 65% of the company’s business.

  • Greater lifetime ROI: Returning customers deliver

  • Reduced costs: on marketing and sales

  • Brand ambassadors: Keeping customers coming back is good for business. Customer needs that are fulfilled and loyalty rewarded more likely lead to positive reviews, great word-of-mouth marketing and more.


How do you measure customer retention rate?


The most straightforward way of assessing how effectively a company is retaining its customers over a period of time is with the customer retention rate (CRR). The result is displayed as a percentage of previous customers that a company has retained over a period of time.


To make it easier, let’s draw it out with a customer retention formula:





The formula for calculating the retention rate is ((number of customers at the end of the period – the number of customers gained throughout)) / number of customers at the start of the period)) X 100.


Start by picking a time period you want to examine (e.g. last 6 months). You can even look at shorter periods with days or weeks.
