Cost Per Acquisition (CPA)

What is CPA?

CPA stands for Cost Per Acquisition and measures how much you spend to acquire one customer or conversion. It is the ultimate efficiency metric for performance marketers, directly tying ad spend to business outcomes like purchases, sign-ups, or leads.

Formula

CPA = Total Ad Spend / Total Conversions

Example

If you spend $1,000 and generate 50 purchases: CPA = $1,000 / 50 = $20. Each customer acquisition cost you $20.
