What Is LTV To CAC?

The LTV to CAC ratio is a key indicator of your business's profitability and scalability. It tells you whether the value you can deliver for each customer exceeds what you spend to acquire them.

To understand what the ratio means, you’ll need to break the LTV to CAC ratio down into its two key components first: LTV (also known as CLTV) stands for Customer Lifetime Value. CAC stands for Customer Acquisition Cost.

What is Customer Lifetime Value

Customer lifetime value (CLTV or LTV) is the total revenue a business expects to earn from a single customer over their entire relationship with the brand. It indicates the long-term financial contribution of each customer, meaning a high LTV suggests strong customer loyalty and a sustainable business model.

How To Calculate Customer Lifetime Value​

A basic LVT formula is:

Average Order Value × Purchase Frequency × Average Customer Lifespan = LTV

Here, purchase frequency can be synonymous to conversion rate, assuming the set definition of a conversion is a product purchase. (Note: A conversion can be defined as any action and depends on the end goal that you want audiences to achieve.)

More complex formulas can include gross margin and churn rate. In some cases, Customer value (Average Purchase Value × Average Purchase Frequency) can also be used. More advanced (and usually more accurate formulas) are run by predictive LTV models that use historical data to forecast future lifetime value among customers.

What Is Customer Acquisition Cost​

Customer acquisition cost (CAC) represents the total cost an ecommerce business incurs to acquire a single new customer. It's a crucial metric for assessing the profitability of customer acquisition efforts and the success of the chosen marketing or customer acquisition channels.

How To Calculate Customer Acquisition Cost​

Customer acquisition cost (CAC) is calculated by:

Total Marketing And Sales Expenses / Number of New Customers Acquired Within A Specific Period = CAC

The value of total marketing and sales expenses includes advertising spend, marketing software, employee salaries, and sales costs. A more comprehensive calculation may even include the Cost of Goods Sold (COGS).

What Is A Good LTV To CAC Ratio?

A strong LTV/CAC ratio signifies that your business is generating more revenue from each customer than it spends to acquire them. This indicates efficient marketing, strong customer retention, and a product or service that delivers significant value. High-performing ecommerce businesses share these LTV/CAC characteristics:

  • Ratio Above 1: At a minimum, your LTV should exceed your CAC. A ratio above 1 means you're making a profit on each customer. A ratio at 1 means you are just breaking even for each customer.
  • Ideal Ratio of 3:1 or Higher: An LTV/CAC ratio of 3:1 or greater is generally considered a benchmark for a healthy, scalable business. This means for every $1 spent on acquiring a customer, you're generating $3 in lifetime value.
  • Consistent Monitoring: The LTV/CAC ratio isn't a static number. It's crucial to track it regularly to identify trends, react to changes in marketing effectiveness, and make data-driven decisions. Optimizing your LTV/CAC ratio involves strategies to both increase customer lifetime value and decrease customer acquisition costs.

Interpreting Your LTV To CAC Ratio Results

Here's what the qualitative assessment from our calculator means:

  • Exceptional (5:1 or higher): Your brand is doing very well! Consider a more aggressive approach to customer acquisition on both sales and marketing fronts to expand your customer base. Your CAC will increase, but your total revenue will grow in the long run.
  • Excellent (3:1 or higher): Your business is in a strong position. Focus on scaling your successful strategies.
  • Good (2:1 - 3:1): Your business is healthy, but there's room for improvement. Explore strategies to further increase LTV or reduce CAC.
  • Fair (1:1 - 2:1): Your business is breaking even or slightly profitable. Significant optimization is needed to achieve sustainable growth.
  • Poor (Below 1:1): Your business is losing money on each customer. Immediate action is required to address this unsustainable situation.
