Cost per Acquisition
Cost Per Acquisition (CPA) affiliate programs are one of the most popular commission models in affiliate marketing, especially among performance-driven affiliates. Unlike revenue share models, CPA affiliates earn a fixed payout for each completed action, such as a signup, registration, or purchase.
This guide explains what CPA affiliate programs are, how they work across different industries, their advantages and risks, and who they are best suited for. It is designed to help affiliates decide whether CPA is the right commission model for their traffic, skills, and monetization strategy.
What Are Cost Per Acquisition (CPA) Affiliate Programs?
Cost Per Acquisition (CPA) affiliate programs pay affiliates a one-time commission when a referred user completes a predefined action.
That action may include:
- Creating an account
- Subscribing to a service
- Completing a purchase
- Making a first deposit
- Verifying an email or phone number
The key difference between CPA and other commission models is that the affiliate gets paid once, regardless of how much revenue the customer generates afterward.
Because of this, CPA affiliate programs are widely used in:
- Finance and trading
- SaaS and apps
- Gambling and betting
- Lead generation
- E-commerce
How CPA Affiliate Marketing Works (Step by Step)
Understanding the CPA process is essential for both users and search engines.
- Affiliate joins a CPA program
You sign up for an affiliate program that offers cost per acquisition payouts. - You promote a specific offer
Offers are promoted through blogs, paid ads, email campaigns, landing pages, or social media. - User clicks your affiliate link
The click is tracked by the affiliate network or advertiser. - User completes the required action
This could be a signup, purchase, or deposit depending on the offer. - CPA commission is credited
Once the action is validated, the affiliate receives a fixed payout.
CPA affiliate marketing is highly performance-oriented, meaning traffic quality matters more than traffic volume.
Common CPA Commission Structures
CPA payouts vary significantly depending on industry, GEO, and offer type. The most common structures include:
Fixed CPA
A flat payout per conversion (e.g. $20 per signup or $300 per qualified customer).

Higher payouts are unlocked after hitting performance milestones.
Qualified CPA
The payout is only triggered after additional conditions are met (e.g. deposit, purchase, verification).
Hybrid CPA (CPA + Revenue Share)
Some programs combine CPA with ongoing revenue share (covered separately on the Hybrid page).
