How forex brokers make money: Spread & markup model
Forex brokers are businesses that facilitate your trades and earn money through small fees and differences on each trade. Here’s how it works:
The spread – The core way brokers earn
A spread is the difference between the price at which you can buy a currency (ask price) and the price at which you can sell it (bid price).
Example:
- EUR/USD buy price = 1.1002
- EUR/USD sell price = 1.1000
- Spread = 1.1002 – 1.1000 = 0.0002 (2 pips)
When you buy and then sell, the broker earns this small difference. While it seems tiny, it happens on every trade, and with many traders or large trade sizes, this adds up quickly.
Markup on spreads – Extra profit for brokers
Traders often think they are directly trading currencies in the forex market. It seems like you are buying or selling EUR/USD at the prices you see on your trading platform, but it’s not exactly direct.
Here’s what really happens:
Forex brokers act as intermediaries. They don’t just display prices; they get pricing from liquidity providers big banks, financial institutions, or other brokers who actually trade currencies in the global market.
Liquidity providers set the base market spread. Many brokers then add a small markup before showing the price to traders to earn extra revenue.
Example:
- Liquidity provider offers a 0.2-pip spread on EUR/USD
- Broker shows a 0.5 – pip spread to the trader
- Broker earns the extra 0.3 pips as profit
This method is common with A-Book brokers, who route your trades to the real market but still earn a small fee without taking on your trading risk.
Fixed vs variable spreads
Before understanding the difference between fixed and variable spreads, it’s important to first know what is spread in forex and how it affects your trading costs.
- Fixed spread: The broker charges the same spread all the time, regardless of market conditions. This is easier for beginners because trading costs are predictable.
- Variable (floating) spread: The spread changes based on market liquidity and volatility. Spreads shrink in calm markets and widen during major news events.
Why brokers use markups
Markups are common with A-Book brokers, who route your trades to the actual market instead of trading against you. This ensures brokers earn revenue consistently without creating a conflict of interest with your trading outcomes.
Commissions, swap & rollover charges
Forex brokers don’t earn only from spreads. They also make money through commissions and overnight charges when you keep trades open. Here’s how each one works.
Commission
- A fixed fee charged by the broker for executing your trade.
- Common in low-spread or zero-spread (ECN/STP) accounts.
- Charged per lot traded, whether you make a profit or loss.
- Example: If you trade 1 lot of EUR/USD and the broker charges $5 per lot, you pay $5 commission.
Swap charges
- A fee charged when a trade is kept open overnight.
- Based on the interest rate difference between the two currencies.
- Applied daily until the trade is closed.
- Example: If you hold a EUR/USD trade overnight, the broker deducts a swap fee.
Rollover charges
- The cost of carrying a trade to the next trading day.
- Applied during the daily market rollover time.
- Usually the same as swap charges.
- Example: If your trade stays open after market close, a rollover charge is applied.
Hidden costs & slippage you should know
Hidden costs and slippage are often overlooked but can quietly reduce your trading profits if you’re not careful.
Hidden costs
- Extra charges that are not clearly shown upfront by some brokers.
- May include wider spreads, withdrawal fees, inactivity fees, or data charges.
- These costs slowly reduce your trading profits over time.
- Example: A broker advertises low spreads but later charges withdrawal or inactivity fees.
Slippage
- Slippage happens when your trade is filled at a different price than you clicked, due to sudden price changes.
- Happens during high volatility, news events, or low liquidity.
- Can work for or against you, but often results in a worse entry price.
- Example: You place a buy order at 1.1000, but it executes at 1.1003 due to fast market movement.
Always keep in mind that hidden costs and slippage can quietly reduce your profits, especially with low-quality or unregulated brokers, so choosing a transparent and regulated broker helps protect your money.
How to choose a broker with transparent pricing
Choosing the right broker starts with understanding how clearly, they display their fees and trading costs.
- Check regulation: Choose brokers regulated by trusted authorities, as they must clearly disclose all fees.
- Review spreads and commissions: Make sure spreads, commissions, and swap charges are clearly listed on the broker’s website.
- Look for hidden fees: Check for withdrawal, inactivity, or platform fees in the terms and conditions.
- Compare account types: Some accounts have low spreads but high commissions compare total costs, not just spreads.
- Test with a demo or small trade: Review trade history to confirm fees match what was advertised.
