Plain-language meaning
Customer acquisition cost, often shortened to CAC, estimates how much a business spends to acquire one new customer over a defined period. It is most useful when the cost period and customer cohort are clear.
Example
If a company spends 30,000 on acquisition activity in a month and gains 600 new customers, CAC is 50 per customer.
Limitations
CAC can change depending on whether salaries, software, agency fees, discounts, brand spend or sales commissions are included. Blended CAC and paid-channel CAC answer different questions.
