Customer Lifetime Value (CLV) : key metric explained
For any SaaS business, Customer Lifetime Value (CLV) is an indispensable KPI. It quantifies a customer's total revenue throughout their relationship with a company. Businesses can make data-driven decisions to boost profitability and drive sustainable growth by understanding and optimizing CLV. This guide will explain the CLV calculation process, explore the crucial LTV/CAC ratio, and provide actionable strategies to maximize your customers' lifetime value.
What is Customer Lifetime Value (CLV) ?
This metric is mainly found in recurring revenue businesses such as SaaS, although it is sometimes used to analyze e-commerce performance. Let's look at calculating customer lifetime value with a concrete example and how it perfectly complements the analysis of CAC or customer acquisition cost.
Definition of CLV and Synonyms LTV and CLTV
Customer Lifetime Value (CLV), also known as LTV or CLTV, is a metric that predicts the total revenue a business can generate from a single customer account over its entire lifecycle. While this metric is particularly vital for recurring revenue businesses like SaaS, it is also useful for analyzing e-commerce performance.
Key Benefits of CLV
- Optimizing Acquisition: By comparing your CLV to your CAC (Customer Acquisition Cost), you can identify the most profitable channels and the most promising segments.
- Enhancing Retention: CLV enables you to target high-potential customers and implement tailored retention strategies.
- Valuing the Business: A high CLV is a strong signal to investors, demonstrating the robustness of your business model.
How to calculate customer lifetime value ?
The method for calculating Lifetime Value varies depending on the industry. For an online retailer, LTV is typically estimated by considering the average shopping basket value, purchase frequency, and customer lifespan. The formula in this context is: CLV = estimated lifetime × average basket × purchase frequency.
A typical formula for calculating LTV for SaaS companies is
CLV = ARPA / monthly customer churn rate

Breaking down key terms : ARPA vs. Churn Rate
- ARPA (Average Revenue per Account): This represents the average Monthly Recurring Revenue (MRR) per subscriber or customer over a specific period.
- Churn Rate: The percentage of customers lost during the same period. For more accuracy, it's often better to calculate churn over a period longer than a month.
For example, if your company loses 2% of its customers monthly, it would take 100/2 = 50 months to lose all customers and the MRR they generate. By dividing the MRR for the period by the churn rate, you can estimate the LTV. So, if your ARPA is $1,000 and your churn rate is 2%, your LTV would be $1,000 / 0.02 = $50,000.
Although LTV is an estimate, it provides SaaS companies—even those with a limited history—a way to calculate customer lifetime value based on actual performance data.
Another approach to calculating CLV involves multiplying ARPA by the gross margin, offering insight into the value generated after direct costs. However, the examples in this article do not consider this formula.
Practical axample: calculating Customer Lifetime Value in SaaS
Let's break down a SaaS company's monthly revenue and customer churn:
- 50 customers purchased an annual subscription at €120 each;
- 100 customers opted for the basic monthly plan at €12 per month;
- 60 customers subscribed to the premium plan at €18 per month;
- The customer churn rate over the past six months was 3%.
To calculate Customer Lifetime Value, we first determine the Monthly Recurring Revenue (MRR), and then the Average Revenue Per Account (ARPA):
- MRR = ((120/12) 50) + (100 12) + (60 * 18) = €2780;
- Total subscribers = 50 + 100 + 60 = 210;
- ARPA = €2780 / 210 = €13.24;
- LTV = ARPA / churn rate = 13.24 / 3% = €441.33.
Therefore, the average customer lifetime value for this SaaS company is €441.33.
The Importance of the LTV/CAC Ratio
Now that we’ve covered the basics of calculating CLV, let's explore how you can use this metric in tandem with your Customer Acquisition Cost (CAC) to drive more strategic decisions.
The LTV/CAC ratio is a crucial metric that complements LTV by measuring the return on investment for customer acquisition. It compares the customer lifetime value to the customer acquisition cost.
A healthy LTV/CAC ratio typically exceeds 3, indicating that each customer generates three times their acquisition cost in revenue. For example, a CAC of €100 should ideally yield €300 in LTV.
- LTV/CAC < 1: Your business is likely unsustainable, as each new customer generates a net loss.
- LTV/CAC = 1: You’re breaking even with acquisition costs equal to revenue.
- LTV/CAC > 3: This signifies a strong foundation for scalable growth.
By closely monitoring the LTV/CAC ratio, businesses can optimize their customer acquisition strategy, allocate resources effectively, and drive long-term profitability.

How to optimize customer lifetime value in SaaS
Knowing how to calculate Customer Lifetime Value is just the beginning. The real value lies in leveraging it to enhance the profitability and sustainability of your business model. Here are some ways to improve this crucial KPI.
1. Increase revenue per customer
Maximizing ARPA—your estimated average revenue per customer over a given period—can significantly boost CLV. Here are some effective tactics:
- Upselling: Encourage customers to upgrade to higher-tier subscription plans.
- Cross-selling: Offer complementary services, features, or products that add value to the existing offering.
- Price Optimization: Adjust your pricing by offering annual subscriptions with incentives to encourage customers to choose more profitable options.
2. Minimize churn to retain customers longer
Reducing churn is crucial for extending customer lifetimes and thereby maximizing their value. Here are some methods to achieve this:
- Improve Customer Satisfaction: Ensure your customers derive maximum benefit from your product or service through regular engagement and high-quality support.
- Retention Strategies: Implement loyalty programs, offer personalized experiences, and strengthen customer service to encourage retention.
- Benchmarking: Regularly compare your churn rate with industry standards to assess your position and adjust your retention strategies accordingly.
3. Foster customer loyalty
Fostering loyalty among existing customers is as important as acquiring new ones. To strengthen this loyalty, it’s important to:
- Communicate Proactively: Maintain open communication and regularly seek customer feedback to identify and address issues before they lead to churn.
- Reward Customer Loyalty: Implement loyalty programs offering exclusive benefits, such as discounts, early access to new features, or limited-time promotions to encourage upgrades and additional purchases.
Conclusion
Customer Lifetime Value (CLV) is a powerful metric that can guide key decisions in your SaaS business. To recap:
- Understand CLV: Know how to calculate it and what it means for your business.
- Monitor the LTV/CAC Ratio: Ensure you get a strong return on your customer acquisition investments.
- Optimize CLV: Increase revenue per customer through up-selling, cross-selling, and price optimization, and minimize churn by enhancing customer satisfaction and implementing retention strategies.
- Foster Loyalty: Use open communication, feedback loops, and loyalty programs to retain customers longer and increase their lifetime value.
By applying these strategies, you can calculate and enhance your Customer Lifetime Value, driving sustainable growth and long-term success for your business.
With the right tools and insights, you can streamline your decision-making process and concentrate on what truly matters—growing your business.
