What is Customer Acquisition Cost (CAC)?
Customer acquisition cost is the total cost of sales and marketing efforts divided by the number of new customers acquired in a given period. If you spend $1,000 on marketing in a month and gain 20 customers, your CAC is $50.
A complete CAC includes everything spent to win customers: ad budget, software, content production, and the cost of any time or people dedicated to acquisition. Leaving costs out produces a flattering but useless number.
CAC only means something in context. It is judged against lifetime value (LTV) — how much a customer is worth over time. A healthy business earns back its CAC well within the customer's lifespan, ideally with an LTV at least three times the CAC.
Why it matters
If you spend more to acquire a customer than they are worth, you lose money on every sale — and growth makes the problem worse, not better. CAC is the metric that tells you whether your growth is profitable or a slow-motion bankruptcy.
Knowing CAC per channel also tells you where to invest. A channel with low CAC and high-quality customers deserves more budget; a channel with high CAC deserves scrutiny or the cut.
