What is Cost Per Acquisition (CPA)?
Cost Per Acquisition (CPA) is a critical marketing metric that measures how much it costs your business to acquire one paying customer through your marketing efforts. It's calculated by dividing your total marketing spend by the number of conversions or acquisitions during a specific period.
Understanding your CPA is essential for evaluating marketing campaign effectiveness, allocating budgets efficiently, and ensuring your customer acquisition strategy is profitable and sustainable.
How to Calculate CPA
Example: If you spent $10,000 on a campaign and acquired 150 customers:
CPA = $10,000 ÷ 150 = $66.67 per customer
