If you’re running a business, it’s extremely important to understand how your customer lifetime value to acquisition cost ratio (or LTV to CAC ratio) impacts your bottom line. In a nutshell, this ratio answers, “Are we making a profit and attracting the right customers?”
Successful customer acquisition means attracting buyers who are most likely to do business with you. But when you have these customers, how do you know if your acquisition methods actually turn a profit? Comparing customer acquisition cost against lifetime value is a great way to calculate this.
Let’s walk through the differences between CAC and LTV, how to calculate the LTV/CAC ratio, and how to get the most from this metric for your business.

Customer Acquisition Cost vs. Lifetime Value
Customer acquisition cost (CAC) is how much your business spends on sales and marketing to attract a new customer.
Lifetime Value (LTV) is the average amount of revenue one single customer generates for the duration of their business with you.
These metrics exist independently, but they also are used as a comparison to help you understand the effectiveness of your acquisition efforts and business profitability.
LTV:CAC Ratio
An LTV:CAC ratio helps you understand your customers’ overall spending with your business based on how much you spend to acquire them.
You’ll see whether you’re outspending on acquisition or missing out on valuable opportunities to gain new customers because you don’t spend enough.
Overall, your ratio tells you if your business is profitable and companies use this metric to guide spending and find a balance between acquisition and retention that achieves profitability.
How to Calculate LTV to CAC
To calculate LTV:CAC ratio, divide customer lifetime value by your customer acquisition cost. Not sure how to calculate these?
Here’s a post from a former HubSpot service employee on how to calculate customer lifetime value. And, here’s a post that will teach you how to calculate customer acquisition cost.
The most common way to interpret results is to view it as an X:1 ratio, where X is the result of your equation and 1 represents one dollar spent on acquisition.
So, for example, if your business’ LTV is $1200 and your CAC is $500, your equation would be
1000/500 = 2.4
Your LTV, rounded, for this example, would be 2:1, where for every $1 spent on acquisition, you get $2 back.
If your business’ LTV is $600 and your CAC is $200, your equation would be
600/200 = 3
And your business’ LTV:CAC would be 3:1.

Once you’ve conducted your equation, how do you know if you have a good score?
What is a good LTV:CAC ratio?
Most experts like Sergey Pirogov, Founder and CEO of molfar.io, agree that 3:1 is a good LTV to CAC ratio. You can interpret it as your business makes 3x what it costs to acquire a customer, or for every $1 spent on acquisition, you get $3 back.
A ratio closer to 1:1 means you’re spending just as much on acquisition as customers spend, so you’re not generating a profit, and you can stand to improve your acquisition strategy.
If your ratio is significantly higher than 3:1, like 6:1, you might not be spending enough on sales and marketing and are missing out on valuable opportunities to attract new customers.

- Focus on conversion rate optimization so it’s easy for prospects to convert into leads and for leads to convert into customers.
- Use acquisition channels that are the right fit for your customers based on their behaviors and needs.
- Build customer loyalty through things like exciting loyalty programs, excellent customer service, and active feedback loops that show customers you’re invested in supporting them.
