CPA (Cost Per Acquisition)
CPA is the marketing cost of turning one new person into a paying customer — the total acquisition spend divided by the number of new depositors it produced.
Definition
Cost Per Acquisition (CPA) is a marketing-efficiency metric: the average amount an operator spends to acquire one new paying customer, calculated as total acquisition spend divided by the number of newly acquired players over the same period. In iGaming the term carries a second, closely related meaning — a CPA deal is an affiliate or media payment model that pays a fixed one-off fee for each qualifying new depositor (a first-time depositor, or FTD) rather than an ongoing share of that player's revenue. What counts as an "acquisition" is defined by the campaign or contract, typically a registered account that makes a qualifying first deposit or meets a minimum-stake threshold. CPA is only meaningful when weighed against the value a player later generates (LTV or predicted NGR): a low CPA is worthless if those players never return, and a high CPA can be sustainable if they do.
Worked example
Suppose an operator spends 50,000 EUR on a paid-search and affiliate campaign in one month, and it produces 500 first-time depositors. The blended CPA is 50,000 / 500 = 100 EUR per acquired player. To judge whether that is sustainable, the operator compares it against expected player value: if an average newly acquired player generates 250 EUR of NGR (net gaming revenue) over their lifetime, a 100 EUR CPA leaves a healthy margin; if they generate only 80 EUR, the operator is paying more to acquire players than they are worth. Under an affiliate CPA deal the arithmetic is fixed per head rather than blended — for example, 120 EUR for each qualifying depositor, paid only once a referred player deposits at least 20 EUR — so an affiliate that sends 40 qualifying depositors earns 40 × 120 = 4,800 EUR that month, regardless of whether those players later win or lose.
Why it matters
CPA is the central discipline of gambling marketing: acquisition is one of an operator's largest costs, and the entire commercial model depends on acquiring players for less than they are ultimately worth. For professionals, understanding CPA — and pairing it with LTV, payback period, and channel-level attribution — is what separates profitable growth from spending budget on players who never return. For learners, it also explains the economics behind the volume of bonus offers and affiliate "best casino" content: these are acquisition tools whose cost is justified by expected future player losses, which is precisely why gambling marketing is tightly regulated and why gambling is entertainment spending rather than an income opportunity.

Note: Two senses of "CPA" coexist and are easy to confuse: the general marketing metric (spend ÷ acquisitions) and the iGaming affiliate/media "CPA deal" (a fixed fee per qualifying depositor); which is meant depends on context. The "CAC" (Customer Acquisition Cost) label is often used interchangeably but is sometimes defined more broadly to include all sales and marketing overhead, not just direct media spend, so treat the two as near-synonyms rather than identical. What qualifies as an "acquisition" (registration, first deposit, a minimum stake, or a "baseline" activity level) is set by each campaign or contract and is not standardised, and all figures above are illustrative. Note that several regulated markets restrict or prohibit CPA-style affiliate deals precisely because paying per depositor can incentivise aggressive or irresponsible acquisition — verify what is permitted in the relevant jurisdiction.
