LTV:CAC, or Customer Lifetime Value to Customer Acquisition Cost ratio, is a vital metric used in marketing and business analysis to evaluate the effectiveness of customer acquisition efforts. In essence, it compares the long-term value a customer brings to a company (LTV) with the cost incurred to acquire that customer (CAC). LTV represents the predicted revenue a business expects to generate from a customer over their entire relationship, while CAC accounts for the expenses incurred in acquiring that customer. The ratio LTV:CAC is a powerful tool for assessing the sustainability and profitability of a company’s marketing strategies.

To calculate LTV:CAC, you first determine the LTV by considering factors such as average purchase value, purchase frequency, and customer retention rate. Once you have LTV, you divide it by CAC, which includes expenses like advertising costs, sales team salaries, and marketing campaigns. A high LTV:CAC ratio (typically 3:1 or higher) suggests that the company is generating more revenue from each customer than it costs to acquire them, indicating a healthy and sustainable customer acquisition strategy.

TL;DR What is LTV:CAC?

LTV:CAC is a metric that compares the lifetime value of a customer to the cost of acquiring that customer. It helps businesses determine the efficiency and sustainability of their marketing efforts.


The importance of LTV:CAC cannot be overstated in the context of marketing. This metric serves as a compass for businesses, guiding them toward strategies that are not only effective in acquiring customers but also in retaining and maximizing their value over time. Here are some key points highlighting its significance:

  1. Strategic Decision Making: LTV:CAC aids in strategic decision-making by providing insights into the return on investment for each customer acquired. This enables companies to allocate resources more efficiently.
  2. Sustainability: Businesses with a high LTV:CAC ratio can withstand competition and market fluctuations better. It signifies that the revenue generated from customers surpasses the cost of acquiring them, ensuring long-term profitability.
  3. Focus on Quality: Instead of pursuing a high volume of low-value customers, LTV:CAC encourages companies to focus on attracting high-value customers who are likely to contribute significantly to the bottom line.
  4. Optimizing Campaigns: By tracking LTV:CAC over time, marketers can fine-tune their campaigns and strategies, ensuring they continue to yield positive results.
