Customer Acquisition Cost

Customer Acquisition Cost, abbreviated CAC, is the total cost an operator incurs to acquire a paying customer across all variable and allocated marketing inputs. For affiliate-driven operators CAC includes CPA payouts, RevShare commissions amortized over the cohort, network fees, creative production, tracking infrastructure, and the share of fixed marketing overhead attributable to acquisition activity. A common formula divides total acquisition spend in a period by the number of new paying customers acquired in that period, though more rigorous practices use cohort-based attribution to avoid distortion from timing mismatches between spend and conversion.

CAC is most useful in relation to Customer Lifetime Value, with the ratio between them governing whether an acquisition channel is economically sustainable. Operators typically set a target payback period, the time required for cumulative gross profit from a customer to equal the CAC paid to acquire them, and use that target to set commission ceilings for affiliate programs. Payback periods in iGaming and forex are usually measured in months rather than years, because cash flow and chargeback exposure constrain how long operators can carry an unpaid acquisition cost on the balance sheet.

Common pitfalls include excluding affiliate commissions from CAC entirely, double-counting hybrid commission payments across acquisition and retention buckets, and reporting blended CAC without channel breakdowns that hide the true cost of underperforming sources. Operators should also distinguish between paid CAC and fully-loaded CAC, with the former covering only direct media and commission spend and the latter including team costs, tooling, and creative production. A clean CAC view enables disciplined decisions about which affiliates, which markets, and which commission models deserve incremental investment versus which need renegotiation or wind-down.
