Customer Acquisition Cost (CAC)

Customer Acquisition Cost (CAC) is the total expense a business incurs to convince a potential lead to become a new customer. This metric is a fundamental component of analyzing the profitability and scalability of a business, as it measures the financial investment required to grow its customer base. A comprehensive CAC calculation includes all sales and marketing costs, such as advertising spend, salaries for marketing and sales teams, creative costs, and technology or software fees, over a given period.

The formula to calculate CAC is: $CAC = \frac{\text{Total Marketing & Sales Spend}}{\text{Number of New Customers Acquired}}$. For example, if a company spends $10,000 on sales and marketing in a quarter and acquires 1,000 new customers, the CAC is $10. Businesses constantly strive to lower their CAC while also improving the lifetime value (LTV) of their customers. A healthy business model is one where the LTV is significantly higher than the CAC, often at a ratio of 3:1 or more.
