CAC

Customer Acquisition Cost - the total cost to acquire a new customer.

Full Definition

CAC (Customer Acquisition Cost) is the total cost of acquiring a new customer, including marketing, sales, and related expenses. It's a critical metric for understanding unit economics and business sustainability. A healthy business typically has an LTV:CAC ratio of 3:1 or higher, meaning customers generate 3x more value than it costs to acquire them.

Formula

CAC = Total sales & marketing costs ÷ Number of new customers acquired
