To calculate CAC, you divide the total cost of acquiring customers by the number of customers acquired within a specific period. The formula is: Total CAC = (Total Marketing Costs + Total Sales Costs) / Number of New Customers Acquired For example, if a company spends $100,000 on marketing and $50,000 on sales in a month, and acquires 1,000 new customers, the CAC would be: CAC = ($100,000 + $50,000) / 1,000 = $150
