Customer Acquisition Cost (CAC)

Definition

Customer Acquisition Cost (CAC) measures how much a business spends to acquire one new customer, including marketing, sales, and sometimes onboarding expenses. It is commonly used in subscription and eCommerce models to understand profitability and budgeting needs. If a brand spends $10,000 on campaigns and gains 200 customers, the CAC is $50. Healthy CAC ensures the business isn't overspending just to drive sign-ups or purchases.

How CAC Is Used

Teams track CAC alongside Customer Lifetime Value (LTV) to see whether growth efforts are sustainable. CAC influences how aggressively teams bid on ads, optimize funnels, and prioritize growth channels. Companies often run experiments across landing pages, onboarding flows, and ad messages to bring CAC down while preserving conversion quality.
