Cost Per Acquisition (CPA) is a marketing metric that represents the average cost of acquiring a single customer. CPA is useful for measuring the efficiency of advertising campaigns and assessing the return on investment for marketing efforts. In Western countries, the term CPA may sometimes be used interchangeably with "Cost per Install (CPI)." In Japan, however, the expression CPA is commonly used to mean "Cost Per Action (CPA)."

A low CPA indicates that many customers are being acquired at a low cost, while a high CPA suggests poor cost efficiency.Evaluating Return on Investment (ROI)Comparing CPA with Customer Lifetime Value (CLV) allows you to evaluate the return on investment of an advertising campaign.
