What is Customer Acquisition Cost (CAC)?

Customer Acquisition Cost, or CAC, is the average amount a business spends to acquire one new customer, including costs like marketing, sales, advertising, tools, and campaign expenses.

Customer Acquisition Cost (CAC) Explained

CAC tells a business how much it costs to get a new customer.

For example, if a company spends $1,000 on ads and gets 10 new customers, each customer costs $100 to acquire.

CAC is important because getting customers should not cost more than the value those customers bring back.

A low CAC usually means the business can grow more efficiently. A high CAC means the team may need better targeting, messaging, pricing, or retention.
