Why Customer Retention is Important?

Retaining customer with different methods

Customer retention is important for any business. It can be more expensive to keep existing customers than recruit new ones. 

We’ll give you all the reasons why your business should focus on customer retention. 

Let’s get started. 

The different ways to retain customers.

What is customer retention?

Customer retention is getting repeat purchases from existing customers. Ideally, the average retention rate for a small business is 20% and for ecommerce owners, it’s around 35%.

In a perfect world, businesses would have a 100% retention rate, but this is near impossible. Customers have a number of reasons to shop with some being location, convenience and accessibility

However, there are strategies businesses can use to increase their retention rate and continue to have existing customers.

Some of those strategies:

  • Improving customer support
  • Creating a loyalty program
  • Using a referral strategy
  • Offering personalized experience

Why is customer retention important?

Customer retention needs to be part of a business’s overall strategy. It’s 5 times more costly to acquire a new customer than an existing customer. 

Furthermore, the success rate of selling to repeat customers is 60-70% while the success rate to new customers is 5-20%. Businesses have to consider the importance of customer retention. 

Here are some of the main reasons.


With customer retention being 5 times cheaper than recruiting new customers, the cost savings alone are a big reason to start implementing strategies. 

The overall goal is to increase the lifetime value of the customer. When customers shop more at your store, they’ll also be spending more. 

This is because they have become familiar with your brand and your products. 

The average repeat customer spends 67% more in the 31st to 36th month of their relationship compared to the beginning interactions.

Word of mouth

Repeat customers are your best marketers. If customers are pleased with your products or service they will easily refer others to your business. 

Word of mouth is a powerful tool because the recommendation is coming from someone that person already knows. People are more likely to trust a friend or family member over an advertisement

By getting customers to talk about your products you’re getting your business name out there in a natural and authentic way. 


Customers that make repeat purchases can provide valuable feedback. These customers have visited your store, digitally or in person and they’ve used your products a number of times. 

By asking for feedback you can be aware of areas of improvement. This information can only help your business grow. 

Often times owners can be overlooking something. Maybe it’s with a product design or website issue. 

You can use the information to make the changes you need, so new customers will also want to make repeat purchases. It’s great to get real feedback from customers that care about your business

How to calculate your customer retention rate? 

Figuring out your customer retention rate can give you a baseline before you start implementing retention strategies. 

Here’s a quick calculation – [(E-N)S] x100 = CRR

Steps to calculating customer retention rate:

  1. Identify a time frame. 
  2. Collect the number of existing customers at the start of the time frame. This we’ll be “S”.
  3. Collect the total of the number of customers at the end of the time frame. This will be “E”.
  4. Determine the number of new customers within the time frame. This will be “N.”

Let’s put this as an example. 

A cleaning company has 60 customers at the start of the month. In that same month, you lose 10 customers but gain 15 new customers. 

  • Number of customers at the end of the period = 65
  • Number of customers at the start of the period = 60

[(65-15)/ 60]x100 = 83% retention rate. The cleaning company has an 83% retention rate.
