Create AccountCommission Calculator
Work out what your broker’s commission costs on a trade, and over a month of them.
Your Result
The calculation runs in your browser. Rates used for currency conversion are indicative — check your broker for the exact figure.
Commission is quoted two different ways and the difference is exactly double. Some brokers say three and a half dollars per lot per side, which is seven dollars by the time the trade is closed. Others quote the round turn directly. Comparing a per-side rate against a round-turn rate makes one broker look half the price of an identical one.
The line worth watching is the monthly figure. A cost that looks trivial on one trade becomes the difference between a profitable month and a flat one once it is multiplied by how often you actually trade, and it is charged whether the trade wins or loses.
When to use it
- When comparing a raw spread account against a commission-free one.
- Before increasing how often you trade, to see what the extra frequency costs.
- When a strategy has a small edge and costs decide whether it survives.
- To convert commission into pips so it can be added to a spread.
Commission is charged per lot, and usually on both opening and closing.
Round Turn = Rate × Lots × 2 (per side) or Rate × Lots (round turn)
Cost In Pips = Round Turn ÷ Pip Value ÷ Lots
Monthly = Round Turn × Trades- Per side means charged twice, once to open and once to close. Round turn means the whole trade. Always check which one a broker is quoting.
- A commission-free account is not free. The cost is inside a wider spread instead, which is why the spread cost calculator sits next to this one.
- The yearly figure assumes the same rate and the same activity for twelve months. It is a scale, not a forecast.
- Some brokers scale the rate down with volume. If yours does, use the rate that applies to your tier.
A raw spread account charging $3.50 per lot per side, trading 1.00 lot forty times a month.
Working: three and a half dollars each way is seven dollars a trade. On EUR/USD, where a pip is worth ten dollars a lot, that is seven tenths of a pip. Forty trades a month is $280, which is what a raw spread account has to save in spread to be worth it.
Is a commission account cheaper than a spread-only account?
It depends entirely on the spread each one offers. Add the commission in pips to the raw spread and compare that total against the commission-free spread. On EUR/USD the two are usually close; on less liquid pairs the gap can be large in either direction.
Why does my broker charge commission on both sides?
Because each side is a separate transaction to them. It is the normal arrangement on raw spread accounts, and it is why quoting the per-side number makes a broker look cheaper than it is.
Does commission come out before or after profit?
It is deducted from the trade, so the profit or loss in your statement is already net of it. That is why a trade that looks like it finished at break-even often shows a small loss.
Does the pair change the commission?
Usually not — the rate is per lot regardless of instrument. What changes is the cost expressed in pips, because a pip is worth a different amount on each pair.
