Multi-Tier IB Payout Cascades
Multi-tier IB structures are the backbone of large-scale Forex partner programs. A broker in Southeast Asia might have 5 master IBs, each managing 30--50 sub-IBs, with some sub-IBs running their own local networks. When a trader in the lowest layer executes a trade, commissions cascade upward through every level. Getting the cascade math right is the difference between a profitable IB network and one that bleeds margin on every lot.
How Multi-Tier Cascades Work
In a two-tier structure, the direct IB (who referred the trader) earns their full per-lot rate, and the master IB above them earns an override commission on the same lot. In a three-tier structure, a regional master IB earns an override on all volume generated by sub-IBs beneath them, who in turn earn overrides from their own sub-IBs. The broker pays the sum of all tiers on every trade.
| Level | Role | Example Rate | Payout Source |
|---|---|---|---|
| Level 1 (Direct IB) | Referred the trader directly | $7.00 per lot | Trader trading activity |
| Level 2 (Master IB) | Recruited the Level 1 IB | $1.50 per lot | Override on Level 1 volume |
| Level 3 (Regional Master) | Manages the Master IB network | $0.50 per lot | Override on Level 2 volume |
| Total broker cost | -- | $9.00 per lot | Sum of all levels |
Every tier you add increases your cost per lot. A $7 direct IB rate becomes $9 with two override layers. If your average spread revenue per lot is $10, your margin is $1 per lot -- a 10% margin that can vanish if you add a fourth tier or increase any single rate by $0.50. Model the full cascade cost before adding tiers.
Cascade Calculation Methods
There are two main approaches to calculating multi-tier payouts. The additive method adds each tier rate on top of the direct IB rate -- the broker pays the sum. The deductive method starts with a total budget per lot and splits it across tiers. Most brokers use the additive method because it is simpler to communicate to IBs, but the deductive method gives tighter margin control.
- Additive: Direct IB gets $7, Master gets $1.50, Regional gets $0.50. Broker pays $9.00 total. Simple but cost escalates with each tier.
- Deductive: Broker budgets $9.00 per lot. Direct IB gets $7.00, Master gets $1.50, Regional gets $0.50. Same outcome but the broker controls the ceiling.
- Percentage override: Master IB earns 20% of the direct IB rate. If direct IB earns $7, master gets $1.40. Scales automatically with rate changes.
- Fixed override: Master IB earns a flat $1.50 regardless of the direct IB rate. Simpler but requires manual adjustment when direct rates change.
Protecting Margin Across Layers
The single largest risk in multi-tier IB programs is margin compression. Every override layer reduces the broker spread revenue remaining after commissions. A broker earning $10 per lot in spread revenue and paying $9 in cascading commissions has a 10% margin -- before operational costs, platform fees, and liquidity costs. Here is how to protect margin without making the program unattractive to IBs.
- Cap the number of tiers at 3 for lot-based models -- beyond 3, the margin math rarely works
- Use commission caps that limit total payout per lot to a fixed percentage of spread revenue (60--70%)
- Apply qualification rules at each tier -- a master IB only earns overrides on sub-IBs who meet minimum monthly volume
- Differentiate rates by account type -- ECN accounts with tighter spreads should carry lower IB rates than standard accounts
- Review cascade profitability monthly by running a margin report per IB tier level
Account Type Differentiation
| Account Type | Avg Spread Revenue | Max IB Cascade | Broker Margin |
|---|---|---|---|
| Standard (1.2 pip) | $12.00/lot | $8.00/lot (67%) | $4.00/lot |
| Pro (0.6 pip) | $6.00/lot | $4.00/lot (67%) | $2.00/lot |
| ECN Raw (0.1 pip + $7 commission) | $8.00/lot | $5.00/lot (63%) | $3.00/lot |
Notice that the same 67% payout ratio produces very different absolute margins across account types. A broker paying $8 per lot on standard accounts has comfortable margin, but paying the same $8 on ECN accounts with $8 total revenue leaves nothing. This is why most brokers configure different IB rate schedules per account type and include account type restrictions in IB agreements.
Set up automated margin alerts that flag when any IB hierarchy is generating volume where the cascading commission exceeds 75% of spread revenue. This early warning system prevents margin erosion from going undetected across large IB networks with hundreds of sub-IBs.
Key Takeaways
- Multi-tier IB cascades pay commissions at every level when a trader executes a trade -- the broker bears the full stacked cost
- Cap IB hierarchies at 3 tiers for lot-based models to prevent margin compression below sustainable levels
- Use the deductive method (fixed budget per lot split across tiers) for tighter margin control than the additive method
- Differentiate IB rates by account type -- standard, pro, and ECN accounts have different spread revenue ceilings
- Run monthly margin reports per IB tier level and set automated alerts when cascade costs exceed 75% of spread revenue

Master IB
A Master IB is an introducing broker who recruits and manages a network of Sub-IBs beneath them. The Master IB earns override commissions on the trading volume generated by their downstream partners in addition to commissions on their own direct referrals.
Sub-IB
A Sub-IB is an introducing broker recruited by another IB (the master IB) rather than directly by the broker. Sub-IBs operate under a multi-tier structure where commissions cascade from the broker through the master IB layer.
Introducing Broker (IB)
An Introducing Broker is a partner who refers new traders to a Forex or CFD brokerage in exchange for ongoing commissions, typically calculated on the trading volume or revenue generated by those referred clients.
CPA (Cost Per Acquisition)
CPA is a commission model where an affiliate earns a fixed payment for each qualifying action, such as a deposit, registration, or purchase, that a referred user completes.
