Customer Acquisition Cost (CAC) measures the total expense required to attract and convert a new customer, including marketing, sales, and related costs. It’s calculated by dividing total acquisition expenses by the number of new customers gained during a specific period. This metric helps businesses evaluate marketing efficiency and return on investment in customer growth strategies.
Example: Spent $10,000 on marketing/sales, got 100 new customers CAC = $10,000 ÷ 100 = $100 per customer
