Payout Models & Monetization ← Back to Full Glossary

CPA (Cost Per Acquisition)

Quick Definition

A performance pricing model where advertisers only pay when a specific, qualifying action (like a completed sale or subscription) occurs.

Formula / Calculation / Syntax

CPA = Total Marketing Spend / Total Number of Conversions (Acquisitions)

Cost Per Acquisition (CPA) is one of the foundational pricing structures in modern performance marketing. Unlike impressions (CPM) or clicks (CPC), CPA transfers media risk from the advertiser to the publisher or affiliate network. Payouts are triggered exclusively upon verified completion of defined conversion events.

Key benefits include predictable unit economics, zero ad spend waste, and alignment with target Customer Acquisition Cost (CAC) thresholds.
