Is it about quantity or quality in customer acquisition? How can you measure if your methods bring profitable customers?

That’s where two essential metrics come into play: Customer Acquisition Cost (CAC) and Customer Lifetime Value (LTV). The LTV: CAC ratio is a very important metric showing the profitability of your marketing efforts, giving you insights into long-term sustainability and success.

We’ll discuss the LTV:CAC ratio’s significance, factors affecting it, accurate calculations, and strategies for enhancement in this article.

Let’s Understand the LTV:CAC Ratio

The LTV to CAC ratio gauges customer profitability by comparing the lifetime value (LTV) to the cost of acquiring them (CAC).

What Is the Customer Lifetime Value?

Customer Lifetime Value (LTV) estimates a customer’s total profit over their entire relationship, considering all purchases, referrals, and cross-selling. It informs decisions on marketing budgets and retention strategies by showing long-term customer value.

Calculating Customer LTV

To understand what is a good LTV, let’s take a look at calculations. The LTV calculation SaaS companies normally use is the following:

Relationship time

This method suits SaaS, marketplaces, or subscription-based businesses with consistent customer spending over a set period. For instance, if monthly customer revenue is $100, their annual LTV calculation would be:

LTV = $100 * 12 = $1,000

If you are an eCommerce or Retail brand, it’s better to use Average Order Value as a basis for calculations:

For instance, in eCommerce company XYZ, if the average order value is $100 and customers shop seven times a year for two years, their lifetime value is calculated as:

LTV = $100 x 7 x 2 = $1,400

Churn rate

If you have a subscription-based model and your average customer revenue is $100 with a churn rate of 15% per month, the LTV calculation would be:

LTV = $100 / 15%

LTV = $666.67

This method emphasizes customer retention and suits subscription models. While these are two examples, various methods exist to calculate LTV. A higher LTV generally indicates more lifetime value, yet what’s deemed good can vary among businesses.

What Is the Customer Acquisition Cost?

CAC represents the total expense to acquire one new customer’s initial purchase, encompassing marketing, sales, and advertising costs.

Calculating CAC

Examples of costs included in CAC calculation are:

Suppose a business spends $10,000 on marketing, $5,000 on sales commissions, and $2,000 on lead generation tools, acquiring 100 new customers in that period.

To calculate the CAC:

CAC = ($10,000 + $5,000 + $2,000) / 100

CAC = $17,000 / 100

CAC = $170

In this example, the Customer Acquisition Cost is $170 per customer. This means that the business spends an average of $170 to acquire a new customer.

How LTV:CAC Ratio Is Calculated

To calculate the LTV:CAC ratio, divide the customer’s lifetime value (LTV) by the customer acquisition cost (CAC).

Let’s say your business has an LTV of $1,000 and a CAC of $170. To calculate the LTV:CAC ratio, divide the LTV by the CAC:

$1,000/$170 = 5.88

The LTV:CAC ratio here is 5.88:1 (or 1:5.88 for CAC to LTV). This ratio indicates that for every dollar spent on acquisition, nearly six dollars in customer lifetime revenue can be expected.

What Makes a Good LTV to CAC Ratio Benchmark

After calculating the LTV:CAC ratio, the next step is to learn what is a good LTV to CAC ratio and whether the score means a favorable result.

Note: It might be different for your specific business based on the industry you are in (eg. very competitive niche), your specific cost structure (eg. selling low-margin products), or your business goals (eg. getting more clients no matter what to raise more money)

Less than 3:1

An LTV:CAC ratio below 3:1 signals unsustainable customer acquisition, implying that the cost exceeds the lifetime value they bring, leading to an unprofitable strategy.

3:1

A 3:1 LTV:CAC ratio indicates a healthy balance, with the customer’s lifetime value three times higher than the acquisition cost. It reflects efficient customer acquisition and a satisfactory ROI for the business.

Higher than 3:1

A ratio above 3:1 is like hitting the jackpot. It signifies that a customer’s lifetime value far exceeds the acquisition cost, reflecting a highly profitable strategy with substantial revenue from each customer.

Challenges with the LTV:CAC Ratio Calculations

Achieving a profitable LTV:CAC ratio comes with its fair share of challenges. Let’s explore some common problems businesses face in accurately assessing and optimizing this metric:

Accurate Data

Getting accurate LTV and CAC data can be challenging. It requires gathering data from various sources, ensuring reliability and consistency. Incomplete or missing data can disrupt calculations, hampering accurate decision-making insights.

Complex Calculations

Calculating the ratio involves considering customer retention, average purchase value, marketing costs, and more. It’s time-consuming and demands careful analysis, posing challenges to accurately crunch numbers and derive meaningful insights.

Attribution Difficulties

Attributing revenue and costs accurately to various channels becomes challenging due to multiple touchpoints in a customer’s decision-making process. This complexity makes it hard to determine each channel’s exact impact on the LTV/CAC ratio.

Customer Behavior Changes

Customer interests and buying habits can swiftly change, complicating the prediction of future customer value and adjustments in acquisition strategies. Adapting to evolving trends is crucial as previous successful approaches might not remain effective.

Scalability

Rapid company expansion can raise acquisition costs. Ensuring sustainable costs involves scaling the lifetime value (LTV) of new customers in line with or above the increased acquisition costs. Balancing this as the business grows demands careful resource and strategy management.

Industry

Comparing the LTV/CAC ratio between SaaS and retail/ecommerce businesses can vary significantly. Finding suitable benchmarks for comparison becomes challenging due to these differences, emphasizing the need to consider your business’s specific context.

Approaches to Increase LTV While Minimizing CAC

Implementing these methods boosts engagement, reduces churn, activates more customers, and fosters lasting relationships, enhancing the overall lifetime value of the customer base.

How to Increase LTV

↑ Frequency

Increase the frequency of customer engagement and repeat purchases. Offer incentives, loyalty programs, or personalized recommendations to encourage customers to do business with you more often.

↓ Churn

Reduce churn by addressing pain points, enhancing satisfaction, and improving retention strategies. Offer excellent support, personalized experiences, and proactive communication for lasting relationships.

↑ Activation rate

Improve the onboarding process to activate and engage customers from the start. Provide clear guidance, tutorials, and personalized assistance to help customers understand the value of your products or services.

↑ Upsells and cross-sells

Identify opportunities for upselling and cross-selling to existing customers, offering relevant products or upgrades that improve their overall experience.

↑ Loyalty

Nurture loyalty by maintaining regular communication, providing exclusive benefits, and consistently delivering value to encourage long-term relationships.

How to Reduce CAC

Paid vs. organic cost

Balance paid and organic acquisition wisely. While paid traffic can get expensive, optimize organic channels by enhancing search rankings, social media engagement, and leveraging affiliates.

Cart abandonment recovery

Send automated emails for abandoned carts, offering incentives like discounts or free shipping to prompt hesitant customers to complete purchases, leveraging collected email addresses.

Streamline onboarding

Streamline onboarding for a smooth customer experience. Offer clear instructions, tutorials, or videos for quick understanding and usage. Consider interactive tutorials or a dedicated onboarding portal.

Customer rewards initiative

Reward and retain customers with exclusive discounts, early product access, or special perks. Consider a loyalty program where points earned lead to freebies or discounts upon reaching a set threshold.

Key Takeaways

The LTV:CAC ratio gauges customer acquisition profitability. Improving recurrence, reducing churn, optimizing activation rates, and nurturing long-term relationships enhances customer lifetime value (LTV).

To reduce CAC, balance paid and organic acquisition, improve conversion rates, assess marketing team efficiency, and analyze acquisition channel costs. Implementing these strategies drives sustainable growth, boosts profitability, and ensures long-term success.
