LTV/CAC Ratio: Meaning, formula & importance

CAC/LTV Ratio

CAC and LTV are two important metrics that every business should track, and the relation between them is key to understanding how you grow.CAC is the amount of money you spend to acquire a new customer, while LTV is the total value of all the purchases a customer makes over their lifetime. To get a clear picture of your business's health, it's important to track both metrics and calculate your LTV/CAC ratio. This ratio will tell you how much money you can afford to spend on acquiring new customers, and whether or not your current customer base is profitable.

There are a few ways to reduce your CAC, such as improving your marketing efforts or streamlining your sales process. To increase your LTV, you can focus on providing more value to your customers through loyalty programs, upsells, and cross-sells.No matter what your LTV/CAC ratio is, tracking both metrics is essential for understanding the health of your business and making informed decisions about where to allocate your resources.

Why a company's CAC/LTV ratio is important

As a startup, you’re constantly being asked to invest in new initiatives and grow your top line. But with limited resources, you can’t just go out and acquire new customers indiscriminately – you need to be strategic about how you spend your acquisition budget.

This is where the LTV/CAC ratio comes in.

CAC, or customer acquisition cost, is the amount of money you spend on acquiring a new customer. This includes all marketing and sales expenses, from advertising to salaries to commission.

Lifetime value (LTV) is the total value of all the purchases a customer makes over their lifetime. This takes into account not only the initial purchase, but also any upgrades, cross-sells, or upsells they may make.

LTV/CAC ratio is therefore the correlation between these two metrics.

How to calculate LTV/CAC ratio

There are two ways to calculate your LTV/CAC ratio:

The first way is to take your total marketing and sales expenses for a period of time (say, one year) and divide it by the number of new customers acquired during that time. This will give you your CAC. Then, take your LTV and divide it by your CAC. The result is your LTV:CAC  ratio.

For example, let’s say you spend $100,000 on marketing and sales in one year, and acquire 200 new customers as a result. Your CAC would be $500 ($100,000 divided by 200). If each of those customers has an LTV of $1,000, your LTV:CAC ratio would be 2 (1,000 divided by 500).

The second way to calculate your LTV/CAC  ratio is to take your total marketing and sales expenses for a period of time (say, one year) and divide it by the number of new customers acquired during that time. This will give you your CAC. Then, take your LTV and divide it by your CAC. The result is your LTV:CAC V ratio.

For example, let’s say you spend $100,000 on marketing and sales in one year, and acquire 200 new customers as a result. Your CAC would be $500 ($100,000 divided by 200). If each of those customers has an LTV of $1,000, your LTV/CAC  ratio would be 2 (1,000 divided by 500).

The CAC/LTV golden number – 3:1

There is no magic number for what a good LTV/CAC  ratio is – it depends on your business model and your specific industry.

In general, though, a ratio of 3:1 or higher is considered healthy. This means that for every dollar you spend on acquisition, you're making at least three dollars in return. Of course, the higher your LTV:CAC  ratio, the better. A ratio of 5:1 or 10:1 is even better, as it means you're generating a significant return on your investment. If your CAC/LTV ratio is below 3:1, it means you're not generating enough revenue from your customer base to cover the costs of acquisition. This is often indicative of a problem with either your marketing or your sales process – or both.

To improve your LTV/CAC ratio, you need to either reduce your CAC or increase your LTV. Reducing your CAC can be done by improving your marketing efforts, such as increasing your conversion rate or reducing your cost per lead. Alternatively, you can streamline your sales process to make it more efficient. Increasing your LTV can be done by selling additional products or services to your existing customer base, or by increasing the frequency or value of their purchases.

Factors can affect your CAC/LTV ratio

There are a number of factors that can affect your LTV/CAC  ratio. For example, if you're selling a high-priced product or service, your LTV is going to be higher than if you're selling a low-priced product or service. Similarly, if your customers are likely to make repeat purchases, your LTV is going to be higher than if they're only going to make a single purchase.

Another factor that can affect your LTV/CAC  ratio is the lifetime of your customer relationships. If you have long-term customers who continue to do business with you for years, your LTV is going to be higher than if your customers only stick around for a few months.

Finally, the source of your customers can also impact your LTV/CAC  ratio. If you're acquiring customers through word-of-mouth or referrals, your CAC is going to be lower than if you're using paid advertising to acquire customers.

How you can improve your LTV/CAC

If you want to improve your LTV/CAC  ratio, you need to either reduce your CAC or increase your LTV. Reducing your CAC can be done by improving your marketing efforts, such as increasing your conversion rate or reducing your cost per lead.

Alternatively, you can streamline your sales process to make it more efficient. Increasing your LTV can be done by selling additional products or services to your existing customer base, or by increasing the frequency or value of their purchases.

You can also improve your LTV/CAC  ratio by focusing on other areas of your business, such as customer acquisition or product development. By doing this, you can offset the impact of a low LTV/CAC  ratio and still grow your business.

How do you calculate LTV to CAC?

To calculate an LTV to CAC ratio, you first need to calculate the customer lifetime value (LTV). This is done by multiplying the average purchase frequency per customer times the average revenue per purchase and then multiplying that result by the retention rate.

For example, if a customer purchases twice a year and spends an average of $50 each time, with a retention rate of 50%, then their LTV would be calculated as follows: ($50 x 2) x 0.5 = $50.Once you have calculated the LTV for your customers, you can then divide it by your total current cost of acquisition (CAC).

CAC can include any costs associated with acquiring new customers such as advertising, marketing materials or fees associated with services like a customer relationship management (CRM). To calculate the LTV to CAC ratio, simply divide the LTV by the CAC.For example, if your total current cost of acquisition is $200 and the lifetime value of each customer is $500, then your LTV to CAC ratio would be 2.5 ($500/$200 = 2.5). A ratio higher than 3:1 indicates that you are successfully investing in customer acquisition and generating sustainable revenue.

A lower ratio could indicate problems with either your marketing strategy or the quality of your offering.

What is a good LTV to CAC ratio?

The optimal LTV to CAC ratio depends on a variety of factors such as the size of your customer base, the type of product or service you offer and your current financial situation.

This means that for every dollar you invest in acquiring new customers, you should generate at least three (or up to five) dollars in revenue from those customers over their lifetime. A higher ratio indicates that you are successfully investing in customer acquisition and are likely generating sustainable revenue.

On the other hand, if your ratio is too low it could indicate problems with either your marketing strategy or the quality of your offering. It’s important to monitor this ratio closely and adjust your strategies as necessary.

The goal should be to maximize your return on customer acquisition investments while still providing a great product or service.  Additionally, understanding your LTV to CAC ratio is essential for calculating return on investment (ROI) from marketing campaigns and measuring overall performance.
