What is Cost Per Acquisition

Cost Per Acquisition (CPA) is a marketing metric that measures the average cost of acquiring a single customer or conversion through a specific campaign or channel. This action could include a purchase, form submission, click, or other predefined outcomes depending on business goals. CPA is commonly used in performance and digital advertising to evaluate campaign efficiency and return on spend. Unlike broader customer acquisition costs (CAC), CPA provides a more granular view, making it essential for optimizing growth strategies, budgeting, and evaluating campaign effectiveness across both for profit and nonprofit sectors.
