Customer Lifetime Value is a key performance indicator all companies should calculate to keep track of their health. You could use multiple CLV formulas to find yours, but which one is the most reliable? You’re about to discover how to measure customer lifetime value so you can have an accurate representation of how profitable your customers are.

What is Customer Lifetime Value?

Customer Lifetime Value (CLV) represents the predicted net profit that a customer generates throughout their relationship with a company. Instead of looking solely at the value brought by a customer at their first purchase, CLV helps you calculate how valuable that customer could be for an unlimited period.

In marketing resources, you will find “Customer Lifetime Value” under different initialisms, such as “CLV,” “LTV,” or “CLTV.” Marketers also refer to the same concept when they say “customer equity.” 

Customer Lifetime Value indicates how healthy your business is. Companies measuring and analyzing CLV realize that their customer-centric strategies should be inspired by their best customers, not their average customers. 

“In the world of customer centricity, there are good customers… and there is everybody else.”Peter Fader

In other words, if you want to generate better profits in the long term, you must focus on the right customers. You need to track CLV to see how good you are at attracting and keeping those profitable customers. 

Why is Customer Lifetime Value Important?

Customer Lifetime Value is one of the most important metrics because it shows you how healthy your business is and keeps all your departments focused on bringing the most value and generating the most profitable customers.

Measuring Customer Lifetime Value helps you answer some of the essential questions for your business:

Do the efforts of your departments work?

Calculating customer lifetime value and constantly keeping track of it allows you to measure the financial impact of your marketing, merchandise, and sales efforts. Customer value optimization is the responsibility of all departments.

Thus, CLV becomes a company-wide measure of your store’s success and helps you use all resources wisely.

> Read all about improving CLV from the customer value optimization guide.

Is your store’s growth sustainable?

Acquiring new customers that never come back after the first purchase is not a sustainable plan for any company. The more repeat customers you have, the higher the chances to increase CLV and keep a steady cash flow.

Plus, keeping an eye on the CLV to CAC ratio helps you adjust the budget for acquisition campaigns and optimize your efforts to acquire more customers like your most loyal ones.

Do you know which are your best-performing products? 

Product assortment has a significant impact on how low or high your customer lifetime value is. If you want to improve your customer lifetime value, look for sticky products, add new ones to your offer, and eliminate the toxic products that generate churn.

Keep in mind that both CLV and product optimization result from interdepartmental efforts – marketing, merchandising, and customer experience.

Do you know what the impact on the bottom line is?

Not all customers are profitable from the first purchase, but that doesn’t mean they can’t become top customers in the long term. Tracking CLV helps you optimize the entire customer journey, from customer acquisition campaigns to onboarding, prevention, and reactivation campaigns.

Comparing customer lifetime value with the costs of acquiring and retaining customers helps balance your efforts to positively impact the bottom line.

Do you know what generates long-term loyalty? 

Knowing the CLV across all customer segments helps you identify who your most valuable customers are. Next, you can dig deeper, looking at what generates customer loyalty and identifying opportunities.

As a result, you can refine your loyalty program, offer your best customers the VIP treatment and make your business stronger regardless of competitors’ aggressive campaigns.

How to Measure Customer Lifetime Value

You can calculate Customer Lifetime Value in multiple ways. 

The easiest way to calculate CLV is by using the following formula:

CLV = customer revenue – the cost of acquiring and serving that customer

As simple as it is, it’s not a reliable one because businesses are more complex than that and other metrics influence CLV.

For a more accurate business overview, companies calculate the historical and predictive customer lifetime value. 

Historical CLV is calculated based on historical data, so you need access to the total purchases and the total gross profit at the individual level (per customer).

The historical customer lifetime value formula is:

Historical CLV = (Transaction 1 + Transaction 2 + … + Last transaction) * Average gross margin

Predictive CLV is calculated based on historical transactional data and behavioral indicators that help you forecast the evolution of a customer’s relationship with your store.

To find the predictive customer lifetime value, you can use the simple or detailed formula.

The formula for the simple predictive CLV is:

CLV = (Average monthly transactions * Average order value) * Average gross margin * Average customer lifespan

In this formula, the average customer lifespan is measured in months. The simple predictive CLV is used to calculate the detailed predictive CLV, so we note the former as “CLVs.”

The formula for the detailed predictive CLV is:

CLV = CLVs * Monthly retention rate1 + Monthly discount rate – Monthly retention rate

You’re already collecting plenty of transactional data for each customer, so calculating CLV shouldn’t be that hard.

Although manually measuring customer lifetime value is better than no measurement at all, manual work is tiring, and you’re prone to errors.

Switching to a solution that helps you calculate CLV automatically means you constantly have updated values, and you can analyze CLV among different segments and during various periods.

Now, let’s take a look at the historical CLV of a fashion retailer. The CLV at the company level increased from USD 145 to USD 165 in a year. The overall evolution of CLV is good, but you want to go more granular and look at the CLV at the segment level.

Below, you can see the CLV for the most valuable RFM segments over the same period. The CLV for Soulmate segment, which includes the most valuable customers of the fashion retailer, had two lows in January and July 2021. To avoid these trends, the company should perform a qualitative analysis, identify why the CLV dropped during these two months, and use the insights to improve future initiatives for this valuable customer segment.

Tips to Increase Customer Lifetime Value

Although retaining customers is cheaper than acquiring new ones, it’s not necessarily easier. It takes time to win your customer’s trust. Details that seem insignificant can put an end to a lasting relationship. 

Here are some tips to help you increase CLV and keep your business healthy:

Attract better new customers

Knowing your ideal customer helps you create better customer acquisition campaigns. Get away from the trap of assumptions and define your ideal customer profile based on updated customer data. One way to avoid misleading customer profiles is using RFM segmentation to identify the best customer segments.

We call the best customers “Soulmates,” and analyzing what they like and what makes them loyal helps you design better campaigns for attracting new customers like the best ones you already have.

Improve the customer retention rate

When you calculate CLV, you need the customer lifespan (CL), which you calculate based on your Customer Retention Rate (CRR). Improving CLV is highly dependent on your ability to retain customers in the long term, so you always need to keep an eye on CRR and your retention curve.

The retention curve shows you how many orders you need to win your customers’ trust and after how many orders they become engaged. If a segment of high potential customers doesn’t come back for multiple orders, you still have to figure out how you can generate a habit in this segment.

Use NPS before and after delivery

When aiming for a higher CLV, you must stay aware of customer feedback – how customers feel about your products and their interaction with your brand. Measuring the Net Promoter Score pre and post-delivery and analyzing the scores helps you predict future customer behavior

If you want to build long-lasting relationships, you must keep track of customer sentiment and act in real-time to resolve complaints and prevent churn. 

> Learn all you need to know about the difference between pre-delivery NPS and post-delivery NPS.

Improve customer support response

Along with monitoring NPS, you also need metrics that help you evaluate the customer support team, such as Time to First Response and Time to Resolution. All these metrics help you know if there are any customer experience issues that you must fix and stay in the way of CLV improvement.

Let customers know you care about them and put in place a system that allows you to answer right away.  You can’t aspect customer loyalty if you can’t keep them satisfied at every interaction.

Pay attention to the Purchase Frequency and the Average Days Between Transactions

The purchase frequency varies across industries, and it’s highly dependent on the habit formed around your offer, the onboarding process, and the experiences you create for your customers. Analyze your best customers’ behavior and purchase frequency and see how you can replicate that behavior among other high potential segments.

Average days between transactions (ADBT) is another important metric that allows you to fine-tune your campaigns to encourage habit forming, increase purchase frequency, and avoid churn. Monitoring ADBT helps you anticipate the next moment of purchase and send the right message at the right time.

Frequently asked questions

What is customer lifetime value, and could you give an example?


Customer Lifetime Value is a prediction of the net profit a customer can bring to your business during their relationship with your brand. For example, a woman ordered for her family the same amount of water every month for the last two years. Each month she paid $95 to the company that delivers bottled water. If the cost of acquisition was $45, then the CLV is $2,235.

How do you calculate the lifetime value ratio?


The Customer Lifetime Value (CLV) ratio or the CLV to Customer Acquisition Costs (CAC) ratio is calculated by dividing CLV by the CAC. If you’re using the net margin to calculate CLV, your CLV should be three times greater than the acquisition cost.

What is the CLV formula?


The simplest and most common Customer Lifetime Value formula is the customer revenue minus the cost of acquiring and serving the customer. For more accuracy, businesses use the historical and predictive CLV formulas: Historical CLV = (Transaction 1 + Transaction 2 + … + Last transaction) * Average gross margin; Predictive CLV = CLVs * Monthly retention rate1 + Monthly discount rate – Monthly retention rate.

How do you calculate the lifetime value of customer LTV?

To calculate the LTV or Customer Lifetime Value, you need access to the transactional data of that customer, including the customer revenue and the cost associated with acquiring and serving that customer. The simple CLV formula is customer revenue minus the cost of acquiring and serving that customer.
