What is cost per acquisition (CPA)?
Cost Per Acquisition, or "CPA," is a marketing metric that measures the total cost to acquire one paying customer. It must include the cost of marketing campaigns or other spending to get a new customer. This metric is usually calculated alongside the average customer lifetime value (LTV), return on investment, or cost per action. These three combined will let you know how well you're doing with your marketing budget. This can also help you with various business decision-making.
