Cost Per Acquisition tells you how much you spend on average to get one conversion — whether that is a purchase, sign-up, or lead. It is the key metric for evaluating whether your campaigns are cost-effective relative to the value each customer brings.

CPA (Cost Per Acquisition) is the average amount you spend to acquire one customer or conversion. It is calculated as Total Ad Spend divided by Number of Conversions. CPA helps you understand whether your advertising is cost-effective relative to the value each conversion brings.
A good CPA depends entirely on your industry and the value of each conversion. For ecommerce, the average Google Ads CPA is around $45. For B2B and SaaS, it can be $100-$133. Your CPA should always be lower than your customer lifetime value to be profitable.
CPA (Cost Per Acquisition) is a broader term that can refer to any conversion action — a purchase, sign-up, or download. CPL (Cost Per Lead) specifically measures the cost of generating a lead. In practice, many agencies use them interchangeably when the conversion goal is lead generation.
