What is CPA in affiliate marketing?

CPA pays a flat fee for every player who makes a qualifying first deposit. How the model works, how it is calculated and what makes a player qualify.

The model in one line

CPA stands for cost per acquisition. It pays you a fixed amount for each player you send who makes a qualifying deposit. The fee is the same whether that player deposits once or stays for three years.

Earnings = qualifying players × CPA rate
Everything else is a question of what counts as qualifying.

Because the fee is fixed before you spend, you can price a campaign in advance: 200 qualifying players on a €250 CPA is €50,000, however the casino's month goes. The CPA calculator works it through from your own click volume.

What makes a player qualify

A CPA is almost never paid on a registration. It is paid when the player clears a bar written into your deal, usually on their first-time deposit (FTD). The common conditions:

  • A minimum first deposit, so a player depositing the smallest amount that unlocks a bonus does not trigger a full fee.
  • Sometimes a wagering requirement: the player has to stake a set amount, not only deposit it.
  • GEO and channel conditions: an accepted country, and traffic from a channel the casino allows.
  • Confirmation by the casino before the fee becomes payable, which is when fraud and chargebacks surface.

What an FTD is, exactly covers the edge cases. Whether a flat fee or a revenue share suits your traffic is covered in CPA vs RevShare.

Common questions

CPL (cost per lead) pays on a registration. CPA pays on a qualifying deposit. CPL rates are far lower because a registration costs the casino nothing and proves nothing, which is why CPA is the norm in iGaming.

No. Negative carryover is a revenue-share concept and only exists where a month can produce a negative figure. A flat fee per player cannot go negative.
