CAC to LTV (Customer Acquisition Cost to Lifetime Value) ratios are a powerful tool for gauging profitability of a business. Calculating CAC to LTV can show how much money is being spent to acquire customers, versus how much value each customer is providing over the course of their “lifetime” (e.g. the average customer is retained for 5 years). It is important for companies to consider CAC to LTV ratios in order to maximize their profit margins, as each customer should yield an overall return on investment (ROI). In this blog post, we'll look at an overview of CAC to LTV ratios, their impact on profit margins, and how you can use them to make better decisions for your business.

What Is a CAC to LTV Ratio?

The CAC to LTV ratio is a measure of cost-efficiency in customer acquisition and is expressed as a ratio of the Cost of Acquisition (CAC) to the Lifetime Value (LTV) of a customer. CAC takes into account all the costs associated with the acquisition of a new customer, such as marketing expenses, employee costs, advertising costs, etc., while LTV takes into account the anticipated revenue an acquired customer will generate over the course of their lifetime interaction with a company.

Description of CAC

CAC, or cost of acquisition, measures the actual cost of acquiring a customer. It is typically expressed as a ratio of the total cost of a marketing campaign divided by the number of customers acquired through said campaign. This figure can be very helpful in gauging the effectiveness of a marketing or sales strategy, and can be used to determine whether increasing or decreasing spending on customer-facing activities would result in a more cost-effective approach.

Description of LTV

LTV, or lifetime value, is the estimate of the total value of a customer's engagement with the business over their time as a customer. This calculation takes into account the customer's average purchase amount and frequency, as well as how long they remain engaged with the company. Calculating this figure is helpful in determining the return-on-investment of acquiring a customer, versus how long they remain a customer, and how much value they generate for the company.

Examples of CAC and LTV Ratios

Figuring out the ratio between the cost of acquisition for a customer (CAC) and their lifetime value (LTV) is a key part of maintaining a successful business. If the CAC is higher than the LTV, the business will not be able to generate a profit by acquiring new customers.

An example of a CAC to LTV ratio calculation

To illustrate how to calculate a CAC to LTV ratio, let's consider a sample business. This business has an average CAC of \$100, which it spends on various forms of marketing and advertising, such as search engine optimization, social media campaigns, and email marketing. The lifetime value of a customer to the business is $500, which considers factors such as how frequently the customer purchases, how long the customer purchases for, and how much the customer typically spends during each purchase.

In this example, the CAC to LTV ratio is 0.2, calculated by dividing $100 by $500. Generally speaking, for the business to remain profitable, the ratio should ideally be under 0.5. If the ratio is higher than that, there is a higher chance the business will be making a loss via customer acquisition.

4. Reasons for Low CAC to LTV Ratios

Organizations face low CAC to LTV ratios for a variety of reasons. Here we discuss two of the most common ones: high rates of customer retention and lack of customer acquisition.

a. High Rates of Customer Retention

Organizations with a high rate of customer retention tend to see a decrease in their CAC to LTV ratios. Over time, those customers who continue to purchase products or services from the business help the business to accrue more value, whereas customers who have just been acquired will still be in their early stages and therefore less valuable to the business.

b. Lack of Customer Acquisition

Organizations that are struggling to attract new customers can also experience low CAC to LTV ratios. These businesses may lack sufficient marketing resources to be successful in customer acquisition efforts, or they may have developed an inefficient strategy that is failing to generate the necessary leads. Without ongoing customer acquisition, the business will be unable to expand its customer base, and this could lead to a prolonged period of low CAC to LTV ratios.

Reasons for High CAC to LTV Ratios

A high CAC to LTV ratio indicates that businesses have difficulty monetizing their customers, leading to a low overall Profit Margin. This ratio is determined by the ratio of Customer Acquisition Costs (CAC) and Customer Lifetime Value (LTV). Understanding the reasons behind high CAC/LTV ratios can help businesses adjust their strategies and increase their Profit Margin. There are two main causes of high CAC/LTV ratios: Poorly targeted customer acquisition and a low pricing strategy.

Poorly Targeted Customer Acquisition

Poorly targeted customer acquisition happens when businesses focus their marketing strategies on potential customers that are not economically viable in the long-term. This means that while they acquire new customers at a lower cost, they fail to engage them and convert them into loyal, profitable customers.

Businesses need to focus on proper customer segmentation, so that they can target the right demographics and decrease the CAC/LTV ratio. This involves understanding the customer's needs, their wants, their interests, and how they might benefit from the company's offerings.

Low Pricing Strategy

Another reason for a high CAC/LTV ratio is a low pricing strategy. Many businesses take a competitive approach to pricing and reduce the price of their products or services. This might lead to lower CAC in the short term, but it also decreases the LTV as customers tend to purchase less or upgrade less frequently.

To increase the LTV, businesses need to consider whether their pricing model is competitive enough and if they can increase margins by offering premium product tiers. Premium products can often generate more revenue from the same customer and help increase the overall LTV. Additionally, businesses can increase their pricing at regular intervals to take into account of inflation, so that they are not losing out on any potential revenue.

Benefits of Maintaining Balanced CAC to LTV Ratios

Maintaining a healthy relationship between customer acquisition costs (CAC) and customer lifetime value (LTV) gives businesses the opportunity to maximize their profits. A good ratio points to a successful business, as managing a high CAC to LTV ratio provides numerous benefits, including lower customer acquisition costs, improved customer retention and higher customer satisfaction.

Lower Customer Acquisition Costs

The ultimate aim of maintaining an optimal CAC to LTV ratio is to reduce marketing costs without sacrificing the quality of the acquired customers. A balanced ratio helps businesses target potential customers with a higher lifetime value, thus reducing CAC. Increased customer lifetime values also reduce acquisition costs per order as businesses can target a larger pool of customers with well-defined objectives.

Improved Customer Retention

When businesses maintain a balanced CAC to LTV ratio, they can ensure their customers remain loyal and make repeat purchases. This elevated level of customer loyalty ensures that customers remain engaged with the business and decrease the need for costly customer retention efforts. Additionally, when customers are happy and more likely to stick with a particular brand, sales will likely increase as it only takes a few loyal customers to generate a steady stream of income.

Higher Customer Satisfaction

High CAC to LTV ratios also imply that businesses are investing more time, resources and money into the customer experience.By providing quality services and products to customers, businesses can foster stronger connections and create a more positive experience.​ This in turn can lead to higher customer satisfaction, which can lead to improved customer loyalty and better returns in the long run.


When managing a business, the CAC to LTV ratio is an important metric to consider. Knowing how to maintain a balanced ratio between customer acquisition costs and customer lifetime value is key to optimizing profit margins. Companies should track CAC to LTV ratios over time and adjust their marketing costs and product prices accordingly to ensure that they are running their business at maximum profitability.

Summary of CAC to LTV Ratios

CAC to LTV ratios measure how much a business spends on acquiring new customers (cost of customer acquisition) compared to their estimated customer lifetime value. A high ratio relative to industry standards is usually an indicator of inefficient customer acquisition.

Importance of maintaining a balanced ratio to optimize profit margins

Maintain a lower CAC to LTV ratio relative to industry standards to ensure profitability. Companies should aim to reduce customer acquisition costs while increasing customer lifetime value to optimize their profit margins. There are a few strategies companies can apply to achieve this, such as:

  • Implementing an effective customer loyalty program to help increase customer lifetime value
  • Evaluating and restructuring marketing campaigns to ensure they are targeting only potential customers with high lifetime value potential
  • Optimizing pricing models to ensure they are competitive while still generating profit and covering customer acquisition costs.
