How To Calculate Customer Acquisition Cost

How do you calculate customer acquisition cost

You can determine your customer acquisition cost by adding all costs associated with your customer acquisition efforts (marketing costs) and dividing that by the number of new customers you acquired as a result. 

Depending on your reporting needs, you may calculate overall customer acquisition cost at a high level or dive into your channel costs or campaign costs to bring in new customers. Below, we offer a few templates and resources to better understand your own customer acquisition costs, including:

Customer Acquisition Cost Formulas

Basic CAC Formula

At its most basic level, the customer acquisition cost formula looks like this:

Marketing Costs (MC) / Number of Customers Acquired (CA) = Customer Acquisition Cost (CAC)



For example, say you want to check how effective your PPC advertising has been over the past week. Let's say you spent $300.00 and acquired 8 new customers. Your customer acquisition cost would be calculated as follows:

$300.00 / 8 = $37.50

And your CAC for that campaign would be $37.50.

But when you start to look at larger marketing campaigns or at your entire marketing efforts for a given period of time, you need a formula that accounts for more detailed expenditures.

More Detailed CAC Formula

This larger formula takes more specific expenditures into account including: wages for sales and marketing staff,  and marketing & sales software used.

(Marketing Costs (MC) + Wages (W) + Software (S) + Outsourced Services (OS) + Overhead for Marketing & Sales (OH)) / Number of Customers Acquired = Customer Acquisition Cost (CAC)


(MC + W + S + OS + OH) / CA = (CAC)

Let’s say you want to figure out your CAC for January, and during January your expenses looked like this:

CAC Component  Value

Marketing Costs (MC)


Wages (W)


Software (S)


Outsourced Services (OS)


Overhead (OH)




New Customers Acquired During January (CA)

$13,125.00/1,235 = $10.63 Customer Acquisition Cost
