One headline number is not the total cost
A Forex or CFD account can combine several types of cost. Some are built into the price, some appear as a separate charge and some arise only when a position or account is used in a particular way. Comparing a minimum spread alone can therefore give an incomplete picture.
The aim is not to find a universally “cheap” broker. It is to identify the costs that apply to the same instrument, account, legal entity, client type and holding period.
Spread
The spread is the difference between the price at which a position can be bought and the price at which it can be sold. It is normally included in the quoted price rather than shown as a separate debit. Spreads can be fixed or variable, and variable spreads can change with liquidity and market conditions.
Words such as “from” or “minimum” describe a lower boundary, not a typical result. A useful disclosure says whether the figure is minimum, target, average or observed; names the instrument and account; and explains the measurement period where an average is used.
Commission
Some accounts add a separate commission to a comparatively raw spread. The commission may be quoted per lot, per side, per round trip, as a percentage of notional value or with a minimum charge. These units are not interchangeable.
For example, a “per side” commission applies when opening and again when closing. A round-trip figure covers both directions. Before comparing two disclosures, put them on the same trade size and opening/closing basis. Also check the account currency and any conversion method.
Overnight financing or swap
Cash CFDs and rolling spot positions can incur a daily financing adjustment when held through a specified cut-off time. The direction of the position, instrument, benchmark rate, broker adjustment and number of calendar days can affect the amount. Weekend treatment may cause more than one day to be applied at once.
This cost can matter more than the opening spread for a position held over time. Forward or futures-style products may treat financing differently, sometimes incorporating it into a wider spread. The product terms, not the label alone, determine the charge.
Currency conversion and other account costs
Costs can also include currency conversion, market-data subscriptions, guaranteed-stop premiums, deposits or withdrawals, inactivity and bank charges. Some are charged by the broker; others can be imposed by a bank or payment provider. “No commission” does not mean “no cost”, and “no broker withdrawal fee” does not rule out an intermediary-bank charge.
A simple illustrative calculation
Assume a hypothetical trade where the spread cost is 8 account-currency units and the separate commission is 3 units when opening plus 3 when closing. The direct opening-and-closing cost would be 14 units before financing, conversion or other charges.
This example does not describe a broker or a market quote. Its purpose is to show why spread and commission must be combined on the same basis.
How to read a cost page
- Identify the legal entity and country version of the page.
- Select the exact account type and platform.
- Select the instrument and trade size.
- Record whether the spread is minimum, typical, average or live.
- Convert commission to the same opening-and-closing basis.
- Add financing for the intended holding period.
- Check conversion, inactivity, funding and optional-service fees.
- Record the date and retain the applicable terms.
The FCA’s review of CFD providers describes spreads, commissions and overnight funding as material parts of price and value, and highlights the need for clear disclosures. ESMA’s MiFID II costs guidance also treats cost information as transaction-specific rather than a generic headline.
Broker pages are examples, not comparisons
Official cost pages from IG, Pepperstone and OANDA show how providers may separate spreads, commissions, financing and non-trading fees. Their structures and figures can change and may apply only to a particular entity or account. FXContext uses such pages to document disclosure structure, not to infer that one broker is cheaper.
The right conclusion
A cost figure is comparable only after its context and unit are aligned. When context is missing, the correct state is “not documented” or “not comparable”, not zero.
