Affiliate program ROI is not universal. A 2x return in one vertical might be exceptional, while in another it signals underperformance. The economics of iGaming, Forex, and Prop Trading create fundamentally different cost structures, customer lifetimes, and margin profiles. Understanding these differences is essential for setting realistic targets and evaluating your program against the right baseline.
iGaming: High Volume, Variable LTV
iGaming affiliate programs typically operate with high customer volumes and highly variable player lifetime value. Casino operators might acquire 1,000 depositing players per month through affiliates, but the top 5% of those players generate 50% of the revenue. This concentration makes program-level ROI misleading without player-level segmentation.

Bet frequency and handle size
RevShare dominates iGaming because player LTV unfolds over months. Operators who pay CPA without retention qualifiers often overpay for one-time depositors. The most profitable iGaming programs use hybrid models with retention-based bonuses that reward affiliates whose players stay active beyond 90 days.
NGR-based RevShare models in iGaming carry negative carryover risk. If a player wins big in one month, the affiliate earns zero RevShare that month and the negative balance carries forward. Factor this into your ROI modeling -- it smooths costs but complicates affiliate cash flow.
Forex: Longer Cycles, Higher Per-Client Value
Forex IB programs have higher per-client acquisition costs but significantly longer customer lifetimes. An active trader who stays with a broker for two years can generate $3,000-$8,000 in total trading commissions. The payback period is longer than iGaming, but the eventual ROI is often higher.

Common Commission Model
Lot-based rebate ($3-$8 per lot)
Key Quality Metric
Monthly trading volume in lots
Lot-based commissions align IB incentives with broker revenue because both parties earn more as trading volume increases. The challenge is that IBs with inactive referrals consume management resources without generating ongoing commissions. Set minimum activity thresholds to maintain ROI discipline.
Prop Trading: Fast Cycles, Repeat Purchases
Prop trading affiliate economics differ from both iGaming and Forex. Revenue comes from challenge purchases, not ongoing trading activity. Customer lifetime value is driven by repeat challenge purchases -- a trader who fails their first evaluation often buys a second or third attempt. The affiliate channel ROI depends heavily on repeat purchase rates.
Metric
Prop Trading Program
Typical CPA Range
$30-$80 per challenge purchase
Average Customer LTV
$120-$350 (including repeat purchases)
Target CAC-to-LTV
1:2 to 1:3
Common Commission Model
CPA per purchase or % of challenge fee
Key Quality Metric
Repeat purchase rate and coupon abuse rate
Prop trading programs see tighter margins than Forex or iGaming because challenge fees are lower and the product lifecycle is shorter. Coupon abuse -- where affiliates or their networks use discount codes to reduce challenge fees -- is a significant margin threat. Track coupon redemption patterns alongside ROI to catch abuse early.
Compare your program ROI against these vertical benchmarks quarterly. If you consistently fall below the target CAC-to-LTV ratio for your vertical, the issue is likely in commission structure, traffic quality, or customer retention -- not channel strategy.
Key Takeaways
iGaming ROI depends on player segmentation -- top 5% of players drive 50% of revenue.
Forex IB programs have longer payback periods but higher eventual ROI due to extended customer lifetimes.
Prop trading margins are tighter -- repeat purchase rate and coupon abuse are the critical variables.
Use vertical-specific CAC-to-LTV benchmarks, not cross-industry averages, to evaluate performance.
Review your program against these benchmarks quarterly and investigate structural issues if you fall below target.
