Why Pay Attention to Customer Acquisition Cost (CAC)?

Business 101 says this:

If you’re selling something, you need to promote it.

Getting new customers usually means spending money.

That money could be spent on any marketing activity, such as paying for Facebook ads, purchasing AdWords, printing out leaflets and posting them or standing on a street and asking people to sign up.

Whichever option you go with, you’ll have to pay.

The AMOUNT you’ll have to PAY, at the most basic level, is your CAC. If you spend $100 on Facebook ads, that’s how much you’ll have to pay your 1st client.

Your CAC is $100. You spend $100 on paid search ads and $50 on direct mailers, but end up only getting 2 new customers.

Your CAC is $75 ($150 2).

This simplified explanation of the CAC equation shows how to calculate CAC.

In our calculation above, we calculated CAC by dividing total acquisition costs by new customers. However, you can calculate CAC by channel by breaking out the spend on a specific medium by how many customers it brought in.

Acquiring new customers and retaining existing ones are two of the most important parts of running a business. This is why it is so important that you monitor your budget and spend, so you can increase your number of customers and minimise your costs.

Understanding your CAC can accelerate your sales funnel and increase your odds of success.

The customer acquisition cost (or CAC) is the total cost of marketing and sales efforts required to acquire a customer.

Below we will look at why it’s important to calculate CAC, what it consists of and how you can do it.

Common mistakes when calculating CAC

Some marketers will try to work around the problem of users converting outside of the desired time period by pinning down their user’s average time between first touch and conversion to then work this into their CAC calculation.

Let’s say that your average user converts 60 days from when they first sign up. A marketer may then suggest adding your past sales and marketing costs that influenced that conversion and dividing that by the current CAC.

You would expect, based on past sales and marketing costs, that 60 days after incurring them, half would be paid off.

In practice, I have found that this rarely happens. Your sales, marketing campaigns, and discounts, for example, will continually change the data in your analytics.

One common mistake when calculating CAC is using an inflexible formula that is based on assumptions. This will not provide meaningful data and might work sometimes, but certainly not all the time.

One common mistake when calculating CAC is using a relative cost per click and conversion rate channel by channel. This can lead to inflexibility by attributing the conversion to the user in the door and using a fluid conversion rate to project conversion success.

This raises the question of how to correctly assign credit to a user for a single advertisement and not all five advertisements they previously saw. The simplest method for most advertisers is to assign credit based on the last impression.

The attribution model uses the user’s interaction with their most recent advertisement or marketing campaign.

The amount of time it takes for a prospect to become a customer is relative to each specific ad campaign, marketing campaign, or marketing medium.

If you attempt to split your CAC into different time frames, your calculations will get too complicated.

For smaller businesses, attribution is a topic that’s probably better left on the back burner.


There are many CAC formulas available for basic business analysis. It is important that you choose the one that is most appropriate for your business and your current needs. Cost per customer acquisition calculator tool can help you determine the costs of acquiring a new customer easily by inputing the required factors like advertising and marketing expenses, the cost of sales, and the cost of customer service.
