Customer Acquisition Cost (CAC)
The total cost of sales and marketing required to acquire a new customer, including salaries, advertising, tools, and overhead.
What is Customer Acquisition Cost?
Customer Acquisition Cost (CAC) is the total expense of winning a new customer. It includes all sales and marketing costs — salaries, advertising, tools, events, and overhead — divided by the number of new customers acquired.
Formula
CAC = Total Sales & Marketing Spend ÷ New Customers Acquired
