What is customer attrition?


Customer attrition, also known as customer churn, is the loss of customers or clients.

To measure customer attrition, it is recommended to use a customer attrition rate which is a marketing indicator used to get the percentage of customers or subscribers that have stopped using your product or service over a given period.

Measuring customer attrition is a fundamental step in analyzing your company's ability to retain customers. And, it will give you information about the general health of your business and the match between market expectations and the features of your product or service.

Voluntary and involuntary customer attrition

When calculating your customer attrition rate, it is important to distinguish customers who leave you by choice and those who leave by force.

Customer attrition is voluntary when the customer decides to stop purchasing your product or service. This may be because he no longer has a need for it or he decided to purchase it from a competitor.

Customer attrition can also be involuntary. This is when customers leave due to factors beyond your control (e.g., they go out of business).

Why should you measure customer attrition?

To understand why customers leave

Customer attrition is useful for companies that offer products or services in the form of a subscription (with recurring payment) such as telecom providers or SaaS publishers.

Customer retention is a key issue for them because they are faced with the highest attrition rates among all industries.

Today, the leading causes of customer attrition are:

1. Poor onboarding

During an onboarding, customers interact with your team and this is where you can make the first positive impact.

They pay for your product or service because they want it to solve a problem for them. If you take too long to show results, they might look for a better alternative.

2. Weak relationship building

It is important to maintain a healthy relationship with your customers. The key is to show them that you are listening to their needs and that you are constantly providing bespoke solutions to solve their problems.

If you do not take care of your customers, someone else will.

3. Poor customer service

To prevent this from becoming a deal-breaker, and driving your customers away from your service, you need to offer fast, responsive customer support.

To define a strategy

Relying on a Key Performance Indicator is helpful, but not sufficient. If you collect data, it is mainly to monitor its evolution. Evaluating your company's attrition rate will allow you to identify the reasons why customers switch to the competition.

It is by measuring that you learn... and take the lead!

Moreover, by identifying your customer attrition rate, you will be able to detect possible weaknesses and find correct actions to implement to improve your solution.

To focus on customer retention

The customer attrition rate also indicates the extent to which the volatility of your customer base affects your sales.

Since the cost of acquiring a new customer is higher than the cost of retaining one, it may be more worthwhile to focus on customer retention to secure your revenue in the long term.

Therefore, a loyal customer should be an asset that you take advantage of since he is likely to purchase more and recommend your brand to others.


How do you calculate a customer attrition rate?

Customer attrition rate formula

First, quantify the following information:

  • the number of customers lost during a given period
  • the number of customers at the beginning of the given period

Then, divide the number of customers lost by the total number of clients over a given period and then multiply by 100 to get a percentage:


Here is an example:

To calculate the attrition rate for a company that had 650 customers at the beginning of the month and 600 customers at the end of the month, the attrition rate formula would be:

  • Number of customers lost: 650 – 600 = 50 customers
  • Number of customers at the beginning of the period: 650
  • Attrition rate formula: 50/650 = .0769 or 7.7%

Gathering this data can be more complex when you are selling a product or service that does not involve repeat purchases or subscriptions. Indeed, it is easier to obtain the number of people that have terminated a contract than it is to identify those who repeat purchase.

How to understand your attrition rate

It is generally recommended to not have an attrition rate of more than 10%. However, this number depends on your product or service and your industry, and it can be much higher for some companies, without being a potential danger.

You can adjust it, by modifying the way it is calculated. Indeed, not all customers have the same value for the company. It is therefore important to segment your customer base and to adapt both the actions taken and the analysis of the indicators.

Other Key Performance Indicators

Calculating a customer attrition rate gives you an idea of the number of customers that you have lost over a specific period. However, this rate is not sufficient to monitor the performance of your company. It is recommended to use other types of Key Performance Indicators as well.

Here are some of the best Key Performance Indicators you can use:

The retention rate

The retention rate, which is a counterpart to the attrition rate, measures the number of clients kept over a given period. It is calculated as follows:


Therefore, if a company has a 20% attrition rate it will have an 80% retention rate.

ARPA and Customer Lifetime Value (CLV)

ARPA is the Average Revenue Per Account (of customers) for a defined period.

This represents how much a customer spends on average during a given month.

For monthly ARPA, divide the revenue generated from monthly subscriptions by the number of monthly customers.

On the other hand, Customer Lifetime Value (CLV) is an estimate of the average gross revenue that a customer will generate before they churn (cancel).


By calculating your CLV, you can set a marketing budget for customer acquisition. Moreover, you can adjust the way you calculate your Customer Lifetime Value by using formulas based on different segments, such as marketing profiles, geographical areas, and so on.

Net Promoter Score (NPS)

This indicator measures the likelihood of your customers recommending your company, service or product to a friend, and the degree of their attachment to the brand.

By using a Net Promoter Score, you will identify:

  • Promoters (score 9-10), loyal customers who will keep buying and referring the brand to others
  • Passives (score 7-8), satisfied customers who are vulnerable to leave if there is a better offer from a competitor
  • Detractors (score 0-6), unhappy customers who can damage your brand through negative word-of-mouth

It is not recommended to use colors on your NPS as it may bias the answers.

How can you reduce customer attrition?

With a general upward trend in recent years, it is becoming necessary to implement marketing campaigns to improve retention strategies and counter customer attrition.

The purpose of a business is to get and keep a customer.

Theodore Levitt, an American economist

Adopting or reinforcing a customer-centric approach may be one of the best techniques to promote customer retention. Therefore, you should focus on improving customer experience to increase customer satisfaction and loyalty.

Here are 4 steps to reduce customer attrition:

Step 1: segment your customer base

To analyze your customer attrition more accurately, segment your customer base and identify the most profitable customers. You will then be able to take actions adapted to different groups of customers that have similar expectations or characteristics (budget, habits, channels used...), to increase their satisfaction.

Customer Relationship Management (CRM) software is the perfect tool to do this with. It allows you to segment your customer base, develop marketing or persona profiles, and follow the entire customer life cycle, from prospect to loyal customer.

By using this type of software, you will be able to pinpoint drivers that encourage different customer profiles to stay with you or switch to the competition.

Step 2: collect consumer data

There are several types of relevant data that you can collect, this includes:

  • customer engagement
  • psychography (opinions, interests, etc.)
  • behavior
  • interactions with the brand in a given environment and on the communication channels used (chatbots, social media, hotline, etc.)

This data can be analyzed to have a better understanding of the expectations and purchasing behaviors of your targets.

Likewise, it is possible to directly ask for their opinion, with surveys and questionnaires, by using tools such as Qualtrics.

Step 3: improve your response time

Offering customers the opportunity to easily interact with your brand has proven to be a source of customer satisfaction. A company that is reactive and proactive in delivering information or solving problems builds a relationship of trust with its customers.

Customers are very sensitive to the quality of their interactions with a brand. Improving your response time limits the number of unsatisfied customers that could spread negative impressions about you to others.

Moreover, a customer engagement platform such as RingCentral Engage Digital is ideal to improve the management of your digital communications, and not miss any opportunity to answer a customer or prospect.

This solution is perfect for telecom companies since there is a high attrition rate in that industry, sometimes as high as 30%. By using RingCentral Engage, you can cover all digital channels and improve customer service by answering your customers, wherever they are.

Step 4: personalize the customer journey

Reinforcing customer relations requires personalized features and messages. To do this, you can create workflows adapted to your targets by following each step of the conversion funnel.

With a CRM or marketing automation solution, you can set up different automated scenarios, focusing on each of the key moments of the customer's purchasing journey to ensure you send the right message to the right target at the right time.

You will guide your prospects or customers throughout all of the steps of their customer journey and increase their loyalty by offering them exactly what they need.


Reward your loyal customers!

To reduce customer attrition, the main challenge for marketers is to retain customers and develop loyalty. Acquiring customers is not enough: once the link is created, it must be nurtured.

You can use the attrition rate to measure customer satisfaction with your brand, measure the impact of your acquisition strategies, but also define or reinforce your retention campaigns.

Identify the reasons for customer attrition, understand the possible points of friction at each stage of the funnel, and design your loyalty programs with this information in mind.



Finally, track your metrics to study the impact of your marketing actions and observe the evolution of the attrition rate over time. This will allow you to gain insights to improve your marketing campaigns for customer acquisition, retention, and loyalty.

Now that we have provided you with all of the right tools to reduce your customer attrition, what will be your first step towards customer retention?
