What it is
Cost Per Acquisition is how much you spend on marketing to win one paying customer — not just a lead, but an actual closed deal. If you spend $5,000 on marketing in a month and it results in 10 new customers, your CPA is $500. Unlike CPL, CPA accounts for the full journey from lead to customer, making it a more complete picture of marketing efficiency.
Why it matters
CPA is the number that tells you whether your marketing is profitable. If your CPA is higher than your average first sale value, you're losing money on every customer you win. If it's well below your customer lifetime value, you have a machine worth scaling.
The mistake most people make
Not tracking CPA at all and relying on gut feel about whether marketing is "working." Without the number, you can't make good decisions about where to invest, what to cut, or when to scale. Know your CPA. It's one of the most important numbers in your business.
