IB commission structures explained: per lot, CPA and hybrid

An introducing broker brings clients; the commission structure decides whether they keep bringing them. Pay too little and good partners leave for a competitor; pay in a way partners cannot check and every statement becomes a dispute; pay for the wrong thing and the program attracts sign-ups that never trade. This guide walks through the models brokerages use, how multi-level splits work, and how to match a structure to the partner in front of you.

Per-lot commission

The most common model pays the IB a fixed amount for every lot their referred clients trade. It is simple to explain and simple to check: a client who trades 10 lots at $8 per lot earns the IB $80. Brokerages often set different rates per instrument group or account type, because the revenue a lot produces differs between them. Commission is calculated on each closed trade, so partners see it grow during the day rather than waiting for month end.

Volume-based commission

Instead of lots, some programs pay per unit of traded volume, for example an amount per million traded. It suits partners whose clients trade varied instruments and sizes, because it scales with the actual exposure rather than the lot count. The trade-off is that it is harder for a partner to check by hand, which makes clear statements essential.

Multi-level splits

In a multi-level program, commission on each trade is shared up the partner tree. Suppose the total paid on a lot is $10 and the program has three levels: the IB who introduced the client receives $7, the Master IB above them $2, and the Master above that $1. A client who trades 5 lots generates $50, split $35, $10 and $5. If a level is empty, its share stays with the brokerage. The rates per level are a business decision; the system's job is to apply them on every trade, exactly and visibly.

CPA: paying per acquired client

Cost per acquisition pays a fixed amount for each referred client who meets a condition. The condition matters more than the amount. Paying on registration invites fake or low-intent sign-ups; paying when the client has verified their identity and made a first deposit, often above a minimum, ties the payment to a real client. CPA suits affiliates who run paid traffic and want a predictable return on each campaign, and partners whose audience will not trade heavily but will open funded accounts.

Hybrid deals

A hybrid pays a smaller CPA for each qualified client plus a reduced share of trading commission afterwards. The CPA covers the partner's acquisition cost; the ongoing share rewards them for bringing clients who stay. For the brokerage, a hybrid lowers the upfront cost of each client while keeping the partner interested in retention.

Tiered bonuses on top

Tiered bonuses add a reward when a partner crosses a volume threshold in a period, for example a higher rate once their clients trade a set number of lots in a month. They encourage partners to grow without raising the base rate for everyone, and they give account managers something concrete to discuss with their best partners.

Matching the structure to the partner

• Regional IB with a sales desk: per-lot commission, sub-IB levels and a detailed partner dashboard
• Media or performance affiliate: CPA on verified, funded clients, with campaign-level tracking
• Educator or community leader: hybrid, a modest CPA plus a share of trading
• Money manager or signal provider: per-lot or volume commission on the accounts they influence

Protecting the program

Every commission model can be gamed if the rules are loose. Paying CPA only after verification and a first deposit removes most fake sign-ups. Running referred clients through the same KYC and country rules as everyone else stops partners from using a side door. Storing each partner's agreement on their record, and logging every rule change, approval and payout, means a dispute is settled by reading the record rather than by memory. Reviewing the share of clients who fund and keep trading, partner by partner, shows where a program is paying for volume that does not last.

Statements partners can check

A partner who can open their dashboard and see each client, each trade and the commission it produced at their level rarely disputes a payout. Statements generated automatically for each period, payouts made from the same report, and the same numbers visible to the partner manager in the back office keep both sides looking at one source of truth.

A worked example of a hybrid deal

As an illustration, not a recommendation: a partner is offered $200 for each referred client who verifies and makes a first deposit above the agreed minimum, plus $3 for every lot those clients trade afterwards. In a month the partner brings 20 qualified clients, earning $4,000 in CPA, and those clients trade 600 lots, earning another $1,800. The brokerage knows its maximum acquisition cost per client in advance, and the partner is rewarded more when the clients they bring keep trading. Changing either number for a new partner is a configuration change, not a new program.

Paying CPA safely

• Define a qualified client precisely: identity verified and a first deposit above a minimum
• Pay one CPA per client, however many accounts they open
• Set a holding period before CPA becomes payable, written into the agreement
• State what happens to a CPA if the qualifying deposit is reversed
• Review the share of CPA clients who trade again, partner by partner

Setting rates you can afford

Start from what a lot or a client is worth to the brokerage, then decide what share of that you are willing to pay for acquisition. Rates that differ by instrument group or account type keep the program profitable when partners bring clients who trade low-margin instruments. Leave room for tiered bonuses so your best partners have something to reach for, and review the rates every quarter against what the program actually produced.

Questions partners ask

When is commission calculated? On each closed trade, as trading data syncs from the platform, so it builds during the day.

Can a Master IB see what sub-IBs earn? The brokerage decides what each IB type can see; a Master IB typically sees the network and the commission flowing up from each level.

When are payouts made? On the schedule written into the agreement, from the commission report for the period, with a statement for each IB.

Can my deal change as I grow? Yes. Rates, CPA amounts and tiered bonuses are set per partner, so a brokerage can move a partner to a better deal when their volume justifies it, with the new terms recorded on their agreement.

What counts as a qualified client for CPA? Whatever the agreement says, usually a verified identity and a first deposit above a minimum. Writing it down precisely is the best protection for both sides.

How RedCherry calculates it

RedCherry's IB management module supports unlimited levels, commission by volume or by lots per level, CPA deals on verified and funded clients, hybrids and tiered bonuses, calculated on every closed trade as data syncs from the trading platform. Partners follow it in a branded IB portal, and the program side is covered in building an IB program that scales. Terms such as CPA and Master IB are defined in the glossary.
