Understanding Customer Acquisition Cost: Importance, Calculation, and Examples

As an entrepreneur or business owner, it’s good to be aware of the costs associated with acquiring a customer. Customer Acquisition Cost (CAC) refers to the amount it takes to get someone to become a new customer. It’s crucial to the success of your business and a metric you can use to measure various marketing and sales strategies. In this article, we will take a closer look at customer acquisition cost, why it’s important, how to calculate it, and real-life examples of how it works.

What is Customer Acquisition Cost?

A customer acquisition cost (CAC) is a metric that measures the cost of acquiring new customers. To calculate CAC, you sum up all lead generation and sales expenses that went into attracting new customers. These costs include marketing campaigns, promotions, incentives, and sales team salaries or commissions.

Why use Customer Acquisition Cost?

It’s crucial to measure customer acquisition cost because it helps businesses determine the profitability of their customer acquisition process. It enables companies to see if they’re spending too much to acquire a new customer or if they’re under-investing. CAC is a fundamental benchmark for any business that wants to remain profitable.

Why is it important to be below Customer Acquisition Cost?

For a business to remain profitable over time, customer acquisition cost must be lower than the customer’s Lifetime Value (LTV). In other words, CAC should be less than the amount of revenue a customer is likely to bring in over their lifetime with your business. If CAC is higher than LTV, then your business might be in trouble, and acquisition strategies need to be changed.

How does it work?

To calculate CAC, you need the following variables:

Total cost of sales and marketing over a given period
Number of customers acquired during that same period
Once you have the above numbers, plug them into the CAC formula: CAC = Total Cost of Sales and Marketing / Number of Customers Acquired.


Let’s say your business spent $10,000 on marketing campaigns, promos, and incentives in a month and gained 50 new customers in that same period. The CAC will be calculated thus:

CAC = $10,000 / 50
CAC = $200

Therefore, it costs $200 to acquire a new customer.

Common Questions and answers:

Can CAC vary between industries?

Yes, it can. For example, it’s more expensive to acquire a new customer in the healthcare or finance industry than in the retail industry.

Can I use CAC to measure the effectiveness of my marketing campaigns?

Yes, you can. CAC will help you evaluate which marketing campaigns and sales tactics generate the most customers and which channels are less effective.

In conclusion, customer acquisition cost is a crucial metric that businesses need to keep track of to remain profitable. It’s essential to measure CAC for each customer acquisition channel, optimize operational efficiency, and maximize ROI. By understanding what customer acquisition cost is, why it’s important to business success, how to calculate it, and real-life examples of how it works, you can make data-driven decisions and grow your business.
