Customer acquisition cost (CAC) is a vital metric in business growth strategies. It measures the total expenses involved in gaining new customers, including marketing, sales, and technology costs. Understanding CAC helps companies assess their profitability and make informed decisions about resource allocation.

Calculating CAC involves various methods, from basic formulas to segmented analyses. By comparing CAC to customer lifetime value, businesses can determine the long-term viability of their acquisition efforts. Factors like industry competition, marketing channel effectiveness, and product complexity all influence CAC, making it a dynamic metric to monitor and optimize.
