What the result means

CAC is what you pay to win one customer. It only means something beside what a customer is worth, so compare it with your LTV. Count new customers only, not repeat buyers.

The formula

CAC = acquisition spend ÷ new customers

A worked example

A month of ads costs 6,000.00 and brings in 150 new customers. Dividing the spend by the customers gives a CAC of 40.00.
