LTV:CAC Ratio for ECommerce: What Is It and How to Improve It

ltv cac ratio image 1

Every business has a different strategy for customer acquisition, but there are certain similarities among startups.

One of the metrics that’s considered before optimizing customer acquisition is the Customer Lifetime Value (LTV) to Customer Acquisition Cost (CAC) ratio (LTV:CAC ratio). For e-commerce, this is the ratio between the average value of a customer and the average cost per customer. 

This can be useful in many ways, and you should include it when deciding how to acquire customers. Correctly understanding this metric enables optimization of customer acquisition by focusing on getting customers in your market worth more than what’s spent on acquiring them.

This post will show you what are LTV and CAC, why they are important, how to calculate the LTV:CAC ratio for e-commerce and discuss its benefits.

 

What is LTV?

LTV, or Customer Lifetime Value (CLV), is a metric that defines the total average annual recurring revenue a customer will bring to your business.

It’s usually calculated as the present value of future income from that customer. If you’re just starting and don’t have any data on your customers’ lifetime value, LTV is usually estimated by calculating some average value for each customer. 

To calculate and predict LTV, you need to know three things:

  • The average purchase frequency rate—how often your customers buy from you

  • The average purchase value—how much they spend per purchase

  • The customer lifespan—how long they stay as an active customer

For example, a typical customer spends about $1000 per month with you for ten months in total before he leaves (or you stop serving him). Then LTV = $1000 * 10 = $10000.

 

What is CAC?

 Customer Acquisition Cost (CAC) is the cost of acquiring a customer or converting a prospect into a paying customer. The metric includes the costs associated with marketing, advertising, sales, and all other efforts a business puts into finding and converting a customer. This is a critical metric for any business as it impacts revenue and gross margin.

Customer acquisition cost can be calculated using this formula: 

Customer Acquisition Cost = Cost of Sales plus Cost of Marketing expenses divided by the Number of New Customers Acquired.

I.e, CAC = cost of sales + cost of marketing/ number of new customers acquired.

 

What is the LTV: CAC Ratio?

When you’re looking to start an eCommerce store, one of the most important metrics to consider is the ratio between customer lifetime value (LTV) and customer acquisition cost (CAC). LTV: CAC ratio can be used to determine whether your store is performing well enough. 

A good LTV: CAC ratio indicates that your eCommerce business has a positive ROI. This section explores the meaning of the LTV: CAC ratio, how it’s calculated, and what constitutes a good LTV: CAC ratio. You’ll also learn some strategies to improve your LTV: CAC ratio.

So what exactly is the LTV: CAC Ratio?

In simple terms, you can think of this metric as the given period it takes for you to make money from a new customer.

For example, you have a customer who purchased $100 worth of products on their first purchase and then an additional $50 worth in future purchases over two years before they unsubscribe from your services or stop buying from you. This would give you an LTV per customer of $150 ($100 + $50 = $150).

Suppose we assume it costs you about $30 in advertising and other marketing costs to acquire this same customer. This means that each dollar spent acquiring customers eventually generates around five dollars in revenue ($150 / 30 = 5).

 

What is the LTV: CAC Ratio Formula?

The formula for calculating your LTV: CAC ratio is as follows:

(LTV/CAC) = (Average Lifetime Value per Customer)/(Average Cost to Acquire Each Customer)

Let’s use an example that demonstrates how the formula works. Say you have a company that sells a product with an average lifetime value of $1000 and an average acquisition cost of $200. That means your LTV: CAC ratio is 5:1. That’s good — it means that every dollar you spend acquiring new customers will result in $5 in profits over those customers’ lifetime.

 

What is a Good LTV: CAC Ratio for eCommerce Businesses?

A good LTV: CAC is highly dependent on the type of business you’re operating. SaaS companies should shoot for around 3:1, and E-commerce companies have a much lower ratio and should vary between 1:1 to 2:1.

When it comes to your business model, the answer will be completely different from another company. 

For example, let’s say you sell a $5,000 product that requires an entire team of field engineers to install, and then over time, you need to provide them with customer support. Your CAC will likely be much higher than a SaaS company that sells an annual subscription for $500. If you have such a high CAC, your LTV will also have to be higher for this ratio to make sense.

The key here is that your LTV should always exceed your CAC (ideally by 3X or more). So if each customer costs you $100 in sales and marketing expenses before they purchase anything, then the average lifetime value of each customer needs to be more than $300 for this expenditure to make sense.

This can vary based on industry verticals and how the product is marketed and sold. The bottom line is knowing what makes sense for your business model and what doesn’t so that you don’t lose money on every sale while hoping that they’ll stay around long enough to break even – because by then, it’ll likely be too late.

 

Ways to Improve your LTV:CAC Ratio

These strategies will increase Customer Lifetime Value (or LTV) without increasing CAC:

  • Find an ideal customer profile.

  • Watch which channels your top customers use to find you.

  • Optimize your pricing strategy.

  • Identify the lifetime habits of your top consumers by segmenting out different customer base.

  • Take constant feedback to reduce customer churn rate.

  • Find ways to upsell, cross-sell, and upcharge.

  • Consider moving away from transactions and giving customers more options for subscriptions and memberships.

  • Improve customer engagement in your app or online and watch for any changes in usage and frequency that can lead to more profit for you.

 

Conclusion

This article provided an overview of the customer lifetime value to customer acquisition cost ratio, its importance, and how it can be determined.

You should now have a strong sense of the importance of the LTV: CAC ratio and how to calculate it. You’ve seen several examples of the metric in action, and you’re aware of some ways to improve it.

Not only does this metric help you better understand how much money you gain from each of the customers added, but also it highlights opportunities for improvement for your company as a whole and how to enhance the gross margin for your brand.

The next time you find yourself examining the financial modeling of your marketing department’s impact on the company’s gross margin and the average revenue, ask your team whether they have checked their LTV: CAC ratio lately. It will surely be worth your while!

FAQs

The RFM model is a marketing model for identifying customers who are more likely to respond to a new offering, based on their past purchasing patterns.

To do RFM segmentation, you first have to determine what the key components of your business model are. This can vary from company to company, but it usually includes things like:

  •  What is your revenue model?

  • How often do people purchase from you?

  • What is your average order size?

Once you know these factors, you need to determine what a high or low-end value would be for each one.

The RFM model is used in customer relationship management (CRM) systems to determine the quality of relationships with customers. If a customer spends a lot of money and does so frequently, they are considered to have a high-quality relationship with the company and should be considered valuable. Conversely, if a customer has made few or no purchases recently, they are not seen as having as high-quality a relationship with the company and are considered less valuable.

RFM is a great tool for small and medium-sized businesses because it helps them use data to target their campaigns and provides a strong framework to build strategies around.

The power of RFM comes in its ability to help businesses make sense of their customer data, segment customers into groups, and then create more effective campaign strategies based on those segments. A business can organize its customers based on spending, recency, and frequency, which helps them see what kind of customer activity is happening in their business.

The reason RFM is so useful for planning marketing campaigns is that it allows you to see which customers are most likely to respond positively to your campaign. This means you’re not wasting valuable time and resources on marketing efforts that won’t pay off; instead, you can focus on those customers who are most likely to respond positively.
