Direct answer
In forex brokerage, “commission” means a fee that the broker charges for executing a trade. It is typically calculated per lot, per trade, or per unit of trading volume, and it is shown by the broker in its fee schedule. Because broker pricing models differ, commission is only one part of what you may pay; the final cost often depends on commission plus the spread (and sometimes additional fees).
Explanation: commission vs spread
A forex trade involves two related pricing ideas:
- Commission: a direct charge for placing/executing the order. If a broker uses commission-based pricing, the commission may be shown as a number (for example, a fee per lot) and then added to your trade costs.
- Spread: the difference between the price you buy at and the price you sell at. Even if a broker does not state a commission, the spread can still represent a cost because the buy and sell prices are not the same.
How they work together:
- In many commission-based models, the spread may be smaller, while the commission is explicit.
- In non-commission models, the broker may present pricing mainly through the spread rather than a separate commission line.
Because these two costs can be combined differently, the most reliable way to understand your actual trading cost is to identify the broker’s pricing model and then calculate the likely total: commission + spread (± other stated fees).
Example checks and what to verify
To interpret commission correctly, use these independent checks based on the broker’s published materials:
- Find the fee basis: Confirm whether the broker states commission per lot, per trade, or using another unit. The unit matters for comparing pricing.
- Check which instruments it applies to: Forex pairs, account types, or order types may have different fee rules.
- Separate commission from spread: Make sure you understand whether the quoted spread already assumes the presence of commission or whether commission is truly separate.
- Look for add-on costs: Some brokers also disclose other fees (for example, charges tied to specific account features). Only fees explicitly stated in the broker’s fee schedule are verifiable.
Limitations and risks
- No universal definition for every broker: The word “commission” is commonly used for a direct fee, but the exact calculation and what it includes can vary across providers.
- Total cost is not the same as commission alone: Even with commission clearly stated, the spread (and any extra fees) can change the real all-in cost.
- Published terms can differ by account and trading setup: Commission rates may depend on account type, volume, or order execution rules, so you should rely on the broker’s current fee schedule for that specific account.
