LTV/CAC Ratio: the Metric You Must Be Aware of in Digital Product Development

CAC, LTV, CAV, Churn Rate: Some Key Metrics You Should Know

CAC, LTV, CAV and Churn Rate are all Key Performance Indicators (KPIs).

While it can convey a variety of pertinent information about the actions and customer base of a company, the LTV to CAC ratio essentially quantifies how efficiently a business uses its resources.

CAC : Customer acquisition cost refers to the average money output needed to gain a paying customer.

LTV : Customer Lifetime Value refers to the total revenue a customer is predicted to generate during the duration of their subscription.

CAV: Refers to the average money output needed to acquire a customer visit.

Churn Rate: Churn rate refers to the number of customers or subscribers who don’t renew their membership or subscription.

Learning how to properly calculate and compare these indicators will allow you to perform an accurate analysis of your project. You’ll then be able to develop strategies to ensure the success of your digital project.

You already know where we’re going with this? Skip to the last section where we explain how to improve your CAC to LTV ratio.

 Customer Acquisition Cost (CAC) Formula

Customer Acquisition Cost includes all expenses related to your brand’s marketing and sales activities for a given period (sales spending + marketing spending). This amount mustn’t include employee salaries as those aren’t directly related to CAC.

The easiest way to calculate the cost of customer acquisition is to divide the sum of your marketing costs and sales investments by the number of paying customers acquired. Correctly calculating acquisition costs is very important to ensure that the rest of your calculations are not biased.

Be careful not to confuse CAC with the cost of acquiring new customers in general (CAV = Cost of Acquiring Visits). Do not include costs related to CAV in your calculations.

Customer Churn Rate

The customer churn rate represents the percentage of customers who unsubscribe or cease to use your product or service. In general, the average product in a recurring subscription usually has a 3 to 5% monthly churn rate.

With this percentage, you’ll be able to calculate the lifetime value of a customer, i.e., the average income that a customer will generate throughout the entire duration of their subscription. This number is also a key indicator of customer turnover and loyalty.

How to Calculate Lifetime Value (LTV)

Lifetime Value (LTV) is the estimated total profit that a single customer will yield to the company throughout their entire relationship or subscription period. If you’re launching a new digital product, it is very important that you understand this formula.

You’ll need to take into account the churn rate. Here’s how to calculate LTV: divide the average revenue per subscriber by the churn percentage. Your subscription software should automatically calculate the latter. This formula will give you the approximate value of a paying customer.

What is the LTV to CAC Ratio?

Now that you understand LTV and that you know how to calculate CAC, you need to figure out how these two metrics relate. The ratio between these two numbers will determine whether or not a customer’s average Lifetime Value (LTV) is high enough when compared to cost of acquisition.

You should be aiming for a 3:1 LTV to CAC ratio. This means that a customer’s lifetime value should be at least three times greater than its acquisition cost.

Why is the LTV CAC Ratio Relevant for your company?

Being aware of your project’s LTV to CAC ratio will allow you to properly assess its sustainability as well as contribute to improving your marketing strategies. It will help you measure the efficiency of your marketing and sales campaigns. 

For example, having a 3:1 ratio is an indicator that your project is not generating enough revenue. Your project is therefore not feasible in the long run. You’ll need to take action to increase profit or reduce Customer Acquisition Costs if you want a healthy business. You could, for example, shorten your sales cycle.

On the other hand, if your ratio is higher than 5:1, then that’s an indicator of growth potential. You could afford to invest more money into project development. 

LTV to CAC ratio will tell you whether or not your business model is viable. It allows you to understand how effectively your company is utilizing its resources. This ratio can give you insight on various aspects of your business, including customer behaviour and overall performance.

How to Increase LTV:CAC Ratio ?

An LTV to CAC ratio lower than 3:1 may indicate that:

  • Customer Lifetime Value is too low
  • Conversion rate is too low
  • Retention rate is too low
  • Customer Acquisition Strategy Cost is too high

To find out where the problem lies and to choose the best strategy for your business, you’ll need to analyze your Key Performance Indicators (KPIs).

Here’s a bit of food for thought:

  • Analyze the CAC payback period: for how many months must a customer keep their subscription for the acquisition cost to be covered? Compare this number with the retention rate. For example, if you need customers to remain subscribed for 8 months ($800) to cover CAC, but you have a 5-month retention rate ($500), then your problem is a low retention rate. You must therefore discover why your customers are unsubscribing so quickly. In this particular example, the ideal retention rate would be 24 months, i.e., 3 times the cost of acquisition.
  • Analyze the conversion rate of your acquisition channels: this will allow you to reduce the cost of acquiring paying customers. You must optimize the conversion steps that are key to a visitor becoming a paying customer. If your conversion rate is low, it may be wise to work on optimization levers or to go with a more efficient acquisition channel.
  • Study your CAC: Is it too high? Could you lower customer acquisition costs by switching communication methods used to reach your target audience? Or simply by using a different acquisition channel?
  • Look into your retention rate: is your churn rate superior to the average churn rate in your field? The number of subscriptions cancelled reduces Lifetime Value (LTV), which has a negative impact on your LTV to CAC ratio. If that’s the case, then the solution to your problem may lie in improving customer loyalty strategies.

Basically, you can improve your ratio by either improving customer value, reducing acquisition costs or improving customer retention.

The Importance of Key Performance Indicators (KPIs)

It’s no secret that being able to track and analyze your company’s KPIs will allow you to make well-informed decisions that will help you achieve your growth goals.

As a business owner, there are several indicators that you can (should) keep track of. The LTV to CAC ratio is probably the most important one to keep an eye on if a digital product is what you’re launching.
