Customer Lifetime Value Definition

Customer lifetime value (CLV) is a key performance indicator from the field of business administration. As a rule, it describes the contribution margin that a customer generates over his entire customer life cycle, discounted to the point in time under consideration. The CLV can therefore be understood as the average value that customers have had for the company over the years or that they will have in the future. Therefore, in addition to past revenues, expected future revenues are also taken into account. When determining customer lifetime value, it is important to separate potential customer value from actual customer value. Potential customer value takes into account a customer's total spend, including competitors' spend in a particular area, while actual CLV only takes into account the customer's own company spend. Companies use CLV to more effectively tailor marketing to their customers. For example, a higher CLV may justify a higher budget for servicing a particular customer.

Calculate CLV: Here's how

You can easily calculate the Customer Lifetime Value in just two steps:You can easily calculate the Customer Lifetime Value in just two steps:

1. record characteristic values:

  • T is the duration of the business relationship.

    eT is the expected deposit of an individual customer.

    aT is the costs incurred in maintaining the customer.

    i is the calculation interest rate, which uses the duration of the entire customer relationship as the calculation variable. Here, the average over the entire customer term is often used.

    In other models, aspects such as sociodemographic factors (income, social environment or other reference variables) or data provided by the customer can be included in the calculations as meaningful values.

    2. calculate CLV: A general formula for calculating CLV:

CLV = (eT – aT) ÷ ((1 + i) × T)

Customer Lifetime Value Example

Suppose you want to calculate the CLV of the customer of a mobile phone provider. The term of the business relationship T is set to 10 years. Therefore, the calculation interest rate is 10%, which is used in the formula 0.1. Every two years, customers buy a new smartphone worth €400 (eT). The manufacturer spends €50 (aT) per year on customer service in the form of correspondence, phone calls and e-mails. Since eT and aT are values that must be related to the duration of the customer's existence, the following is calculated in advance: 5 × 400 = EUR 2000, 50 × 10 = EUR 500. Now put the value into the CLV formula:

CLV = (2000 – 500) ÷ ((1 + 0,1) × 10)

CLV = 136,36

The customer's CLV is thus 136.36 euros per year. Optionally, further aspects can be included here. For example, if a customer has recruited another, this new customer can be included in the calculation. The resale rate or cross-sellings can also be used. Accordingly, there are various models for calculating the Customer Lifetime Value.

Customer Lifetime Value: How to track it in your online store

To track Customer Lifetime Value (CLV) in your online store, you need a suitable analytics tool and the relevant data. Here are some steps on how to track CLV in your online store:

  1. Collect data: To calculate CLV, you need information about customers' purchases and their order history. Make sure you have a database that contains information such as order totals, purchase date, customer ID, and products.

  2. Use an analytics tool: To perform the calculations, a reliable analytics tool or e-commerce platform is helpful. Tools like Google Analytics can help you collect the necessary data and track CLV.

  3. Segmentation: look at CLV in different segments, e.g. by customer groups, product categories or marketing campaigns. This will allow you to develop more targeted strategies to increase CLV for specific audiences.

  4. Update your data regularly: Since CLV depends on actual customer engagement and buying behavior, it's important to regularly update your data and review your calculations.

Customer lifetime value is an important metric for evaluating the profitability of your online store and fostering long-term customer relationships. By collecting and analyzing data, you can better understand how much value an average customer represents to your business and what strategies you can implement to increase that value.

CLV: The advantages and disadvantages of customer lifetime value

Now that we know how Customer Lifetime Value is calculated, let's take a look at the benefits of knowing this value for your business. After that, we will also look at the weaknesses of the CLV.

Advantages of the CLV

1. increasing CLV can increase sales over time.

The longer the life cycle or the more value the customer brings into this life cycle, the more revenue the company generates. Measures to optimize the CLV, e.g. cross-selling or upselling, therefore lead to higher sales.

2. CLV can help identify problems and thereby increase customer loyalty.

By prioritizing CLV in your organization, you can identify worrying trends and take action to correct them. For example, if you find that your CLV is consistently low, you can optimize your customer service strategy or loyalty program to better meet your customers' needs.

3. it helps you to target the optimal customers.

If you know your customer's lifetime value, you'll also know how much they spend with your company over time - so whether it's 50, 500 or 5,000 euros, for example. With this knowledge, you can develop a customer acquisition strategy that targets the customers who buy the most from your company.

4. increasing CLV can help reduce the cost of customer acquisition.

Statistics show how important it is for companies to identify the most valuable customers and nurture the customer relationship. This way, you can achieve higher profit margins, higher customer lifetime value and lower customer acquisition costs.

Reading tip: Conversion rate optimization is another key factor for sustainable business success.

Disadvantages of the CLV

However, the CLV also has its weaknesses. In particular, the sales expected in the future are an estimate. They could turn out to be considerably smaller than assumed or even fail to materialize at all. In addition, it requires a usable database to calculate the CLV. In e-commerce in particular, it can be difficult, for example, to assign all transactions to a singular customer in order to achieve a usable database for the CLV while at the same time complying with privacy and data protection.

Increase Customer Lifetime Value: These 8 methods make it happen

You now know what CLV is, how important it is to know it, and how you can calculate it. Now it's time to demonstrate methods you can use to increase your Customer Lifetime Value.

1. improve onboarding process

The onboarding process is the period of time during which you introduce your customers to your brand and products, slowly building trust and a relationship. By optimizing this process, you can create a framework for long-term customer relationships and, over time, increase your CLV.

2. increase AOV

The AOV is the average order value. If this is increased, the customer lifetime value can of course also be improved. This can be achieved, for example, by offering relevant additional products to the products the customer is about to buy (cross-selling). Even if it's just a low-cost additional product, this method can add up and increase revenue and CLV over time.

3. maintain customer relationships

If you build a real relationship with your customers and maintain it for the long term, this will increase their satisfaction, they will buy from you again and again, and you can significantly increase the CLV of these buyers. To improve the relationship with your customers, you can take various measures. First of all, it is important to establish a continuous connection. After all, the easier it is for your clientele to get in touch with your brand, the more trustworthy they seem and the more connected buyers feel with your company. Of course, a continuous connection is closely related to good customer service. However, you should not only be easily accessible, but also create other positive experiences for your customers in terms of support. This can include good return policies, for example, as this will make your buyers feel that quality and satisfaction are priorities for you and that you are not just concerned with sales. The result: a satisfied customer experience means a higher CLV in many cases. Who can give you more informed suggestions for improvement and feedback on your products than your clientele? That's right: no one. They use your products or services, which is why your buyers' opinions should matter to you. So take advice from your customers. This can not only optimize your products, but also foster long-term loyalty among your customers, thereby increasing CLV.

4. introduce loyalty programs

Loyalty programs are another effective way to increase CLV. Various benefits and special offers result in your clientele becoming more loyal to your brand. Loyal customers are not only more likely to purchase from your business themselves, but they are also more likely to recommend it to friends and colleagues. For this reason, you should consider such a program and, if possible, always offer added value to your buyers.

5. increase product quality

While customer relationships should play an important role in any business, don't forget the importance of product quality. Problems or inferior products can have a big impact on your CLV. This, of course, can quickly affect the brand's reputation. Therefore, ensuring good product quality is a necessary condition for the sustainable development and growth of the company.

6. Use customer feedback

Listen to your customers' feedback and turn it into tangible improvements. Customers who feel heard and valued are more likely to continue supporting your brand.

7. Email marketing

Use email marketing to regularly update your customers on news, offers and relevant information. Keep the dialogue going to strengthen customer relationships.

8. Customer service

Exceptional customer service is critical to satisfying customers and building long-term customer relationships. Quick response times, easy return policies, and problem resolution all contribute to customer loyalty.


As we have now established, calculating CLV is often very good for business. Understanding the value of a "customer life" can help the marketing and sales department in particular to allocate marketing budgets appropriately or reactivate customers at risk of inactivity. Separating profitable customers from unprofitable ones also prevents bad investments and creates the conditions for sustainable customer relationships. Even though you should know and understand the CLV calculation formula, you may still rely on reporting tools and a modern CRM for implementation.
