Frequently Asked Questions
What is cost per acquisition?
CPA is the average cost to acquire one customer or conversion. It is calculated by dividing total campaign spend by the number of acquisitions. Lower CPA means you are acquiring customers more efficiently.
How is CPA different from CAC?
CPA typically refers to a single campaign or channel cost per conversion. CAC (customer acquisition cost) is broader, including all sales and marketing spend across all channels divided by total new customers. CAC gives the full picture; CPA measures individual campaign efficiency.
What is a good CPA?
Your CPA must be lower than the profit you earn from each customer. If a customer generates $200 in profit, a CPA under $200 is profitable. Target a CPA that is 20-30% of customer lifetime value for a healthy margin.
