Understanding the Difference: Lifetime Value (LTV) and Customer Lifetime Value (CLV) in SaaS


In the Software as a Service (SaaS) realm, the usage of metrics to gauge business health and growth is ubiquitous. Two often-confused metrics are Lifetime Value (LTV) and Customer Lifetime Value (CLV). At first glance, they seem interchangeable; however, subtle differences distinguish these two key performance indicators (KPIs). This blog post aims to explore and clarify the difference between LTV and CLV, shedding light on their distinct roles in your SaaS business.

What is Lifetime Value (LTV)?

In the context of SaaS, Lifetime Value, or LTV, is a prediction of the net profit attributed to the entire future relationship with a customer. The importance of LTV lies in its relationship with Customer Acquisition Cost (CAC). Your LTV should ideally be at least three times your CAC for a sustainable SaaS business model. LTV helps you make informed decisions about how much money to invest in acquiring new customers and retaining existing ones.

Understanding Customer Lifetime Value (CLV)

Customer Lifetime Value, or CLV, is a slight variation of LTV. It is also a predictive metric that estimates the total monetary value a specific customer is expected to bring to your business over the duration of their relationship with your company.

While similar, CLV provides a more customer-centric perspective, focusing on maximizing the value of each individual customer. This view is especially crucial in the SaaS world, where nurturing customer relationships is key to recurring revenue.

The Difference Between LTV and CLV

While both metrics seem similar - and they are, in that they both look at the value a customer brings over the duration of their relationship - there are subtle differences.

LTV is generally used to understand the overall value derived from an average customer, considering factors such as churn rate, recurring revenue, and gross margin. It helps companies understand how long it takes to recoup the investment made in acquiring a new customer.

On the other hand, CLV is used to understand the value derived from a specific customer, often used to segment customers based on their value. This helps companies identify high-value customers and tailor their marketing and retention strategies accordingly.

Why are LTV and CLV Important?

LTV and CLV are vital metrics that help businesses make informed decisions about sales, marketing, product development, and customer support. Understanding these metrics can aid in the development of strategies to increase the value derived from customers over their lifespan, thus increasing profitability.

For instance, a company with a high LTV can afford to spend more on customer acquisition and retention. On the other hand, companies with a high CLV might want to focus more on nurturing and upselling to their high-value customers.

The Role of LTV and CLV in Customer Segmentation

Diving deeper into LTV and CLV's functionality, these metrics can significantly contribute to more precise customer segmentation. By distinguishing high CLV customers, you can identify your most valuable clientele and the sources they come from, helping you concentrate your resources and marketing efforts where they count the most.

Adjusting LTV and CLV over Time

Another important aspect to remember is that both LTV and CLV are not static metrics. They evolve with your business growth, market changes, and customer behavior shifts. Regularly updating and adjusting these metrics can provide a more accurate, real-time understanding of your customer value, ensuring your strategies stay relevant and effective.

LTV, CLV, and MRR: The SaaS Growth Triad

LTV and CLV become particularly impactful when considered alongside Monthly Recurring Revenue (MRR). While LTV and CLV focus on the value from customers, MRR represents the predictable income generated from those customers. Balancing the pursuit of high LTV and CLV with steady MRR growth forms a powerful strategy for SaaS success and profitability.


While LTV and CLV may seem similar, they offer different perspectives on the value derived from customers. Both are valuable metrics that, when used in conjunction, can provide a more comprehensive view of a company's profitability and long-term growth potential. Understanding these metrics is crucial for any SaaS company looking to increase its profitability and achieve sustainable growth.
