Broker Business Model Explained: Where the Revenue Comes From
Before choosing technology, be clear about how your brokerage earns. Revenue model determines your pricing, your risk approach, the clients you attract and the vendors you need. This guide sets out the standard revenue lines and the cost structure they sit against.
Spread markup
You receive a raw price from your liquidity provider and quote a slightly wider one. The markup is revenue on every trade, is invisible to most clients, and scales directly with volume. It is the most common primary revenue line in retail broking.
Commission
A per-lot or per-side fee on top of a raw spread. This is the ECN or raw-account model, preferred by active and algorithmic traders because pricing is transparent. It usually produces lower revenue per trade but attracts higher-volume clients.
Swap and financing
Overnight financing on leveraged positions, charged as swap in FX or as a financing rate on CFDs. For clients who hold positions for days or weeks this can exceed spread revenue, and it is frequently under-managed by new brokers who copy their provider's rates without reviewing them.
Internalisation and risk revenue
When client flow offsets internally, or when you retain a portion of unhedged exposure within defined limits, the profit or loss on that book becomes a revenue line. It is the highest-variance part of the model, requires real risk infrastructure and governance, and must be disclosed and managed in line with your regulatory obligations.
Ancillary revenue
Inactivity and administration fees, currency-conversion margin, premium data or tooling subscriptions, and VPS or copy-trading add-ons. Individually small, collectively meaningful, and easy to overdo at the expense of client trust and regulatory comfort.
The cost side and what drives profit
Against revenue sit liquidity and platform fees, payment processing, salaries, and client acquisition. Profitability is mostly decided by three numbers: cost per funded client, average revenue per client, and client lifetime. A broker with mediocre pricing and excellent retention beats one with sharp pricing and churn.

Frequently asked questions
Do brokers profit when clients lose?
It depends on the execution model. A fully hedged broker earns from spread, commission and swap regardless of client outcomes; a broker that retains risk internally has exposure to client results, which is why risk governance and disclosure matter.
Which revenue model is best for a new broker?
Most start with spread markup because it is simple and scales with volume, then add raw-spread commission accounts to attract higher-volume and algorithmic traders.
