How to Calculate Customer Acquisition Cost (CAC)
CAC is calculated by dividing the total cost of sales and marketing by the number of new customers acquired in a given period. This includes every expense dedicated to acquiring customers, such as digital advertising, team salaries, software, events, and commissions.
Customer Acquisition Cost (CAC) = (Total Marketing Costs ($) + Total Sales Costs ($)) / Number of New Customers
Example: If your total spend was $7,500 and you acquired 125 new customers, CAC = $7,500 / 125 = $60.
