How to Calculate Forex Commission

Five steps, and the first one decides the rest.

Pick the commission model

Per lot, per side, round-trip, percentage, per unit or fixed. The model decides the whole calculation, so choosing the one your broker uses is the most important step.

Enter the rate and position

The rate field is labelled for the model you chose, and the position is given in lots or units. Contract size is a field, not an assumption.

Set the sides where they apply

For a per-side rate, say whether the trade is one-way or round-trip. A round-trip rate already covers both sides and is never doubled, and the tool keeps the two apart.

Add a minimum or cap if any

If your broker floors or caps commission, enter those under broker assumptions. They are applied only when entered, and the calculated figure is shown beside the applied one.

Read entry, exit and total

The total commission is the headline; entry and exit are shown separately, and commission in pips tells you the break-even move it represents.

The Same Trade, Six Commission Models

One standard lot of EUR/USD at 1.10, a $3.50 base rate.

Model	Total on 1 lot
Per lot (one-way)	$3.50
Per side (×2)	$7.00 entry $3.50 + exit $3.50
Round-trip $7 rate	$7.00 charged once, not doubled
Percentage 0.0035% / side	~$7.70 of a $110,000 notional
Per unit $0.00003 / side	$6.00
Fixed $2 + $2	$4.00

The same position runs to very different totals depending on the model. The two traps are doubling a round-trip rate, which already covers entry and exit, and forgetting to multiply a per-side rate by two. This calculator runs each model on its own path, so the number matches your statement rather than an assumption.

Raw Spread or Commission-Free? Compare Them in Pips

One standard lot of EUR/USD, where a pip is $10 and the raw account quotes an assumed 0.1 pip spread.

Commission a side	Round trip	That is, in pips	Raw account, all in	Standard is cheaper below
2.00	4.00	0.40 pips	5.00	0.50 pips of spread
3.50	7.00	0.70 pips	8.00	0.80 pips of spread
5.00	10.00	1.00 pips	11.00	1.10 pips of spread
7.00	14.00	1.40 pips	15.00	1.50 pips of spread

The last column is the whole comparison in one number. At 3.50 a side, the raw account costs 8.00 for the round trip, which is the same as a commission-free account quoting 0.80 pips. If the standard account you are comparing quotes wider than that, raw is cheaper. If it quotes tighter, the standard account is. There is no third answer, and no account type is better in general.

The reason this is worth doing rather than guessing is that the two costs are advertised in different units, and a commission in dollars per lot feels unrelated to a spread in pips until you divide it by the pip value. Once both are pips, the marketing disappears and you are comparing two numbers.

Three things this leaves out on purpose. Commission scales exactly with position size while the spread does too, so the comparison holds at any lot size, but only if you compare like with like. Swap is charged on both account types and does not enter this at all. And a raw spread of 0.1 pips is an assumption for the sake of the example: real spreads move with liquidity, widen around news and differ by broker, so put your own figures into the calculator above rather than trusting any table, including this one.

The Formulas, With Worked Numbers

Mostly a $3.50 rate on one standard lot.

What	Formula	Worked example
Position units	Units = Lots × Contract size	1.00 × 100,000 = 100,000 units
Per-lot commission	Commission = Rate per lot × Lots	$3.50 × 2 = $7.00
Per-side commission	Commission = Rate × Lots × Sides	$3.50 × 2 × 2 = $14.00
Round-trip commission	Commission = Round-trip rate × Lots	$7.00 × 2 = $14.00 (not ×2 again)
Percentage commission	Commission = Units × Price × % × Sides	100,000 × 1.10 × 0.0035% × 2 = $7.70
Per-unit commission	Commission = Units × Rate per unit × Sides	100,000 × $0.00003 × 2 = $6.00
Fixed commission	Commission = (Entry + Exit) × Trades	($2 + $2) × 1 = $4.00
Minimum applied	Applied = MAX(Calculated, Minimum)	MAX($1.20, $2.00) = $2.00
Maximum applied	Applied = MIN(Applied, Maximum)	MIN($9.00, $8.00) = $8.00
Effective commission %	Effective % = Commission ÷ Notional × 100	$7 ÷ $110,000 × 100 = 0.0064%
Commission in pips	Commission pips = Commission ÷ Pip value	$7 ÷ $10 = 0.70 pips
Total trading cost	Total = Spread + Commission + Swap + Other	$12 + $7 + $3 + $0 = $22.00
Net P&L after cost	Net = Gross − Commission − Spread − Swap − Other	500 − 7 − 12 − 3 = $478

Things Worth Knowing

The assumptions behind every number on this page.

Round-trip is never doubled. A round-trip rate already covers entry and exit, so it is charged once on your lots. A per-side rate is the one that is multiplied by two sides. Mixing the two, by doubling a round-trip figure, is the most common commission mistake, and this tool keeps them apart.

Percentage commission is a percent of notional, not of profit. Notional value is units times price, so it is large: one standard lot of EUR/USD at 1.10 is $110,000, and even 0.0035% of that is $3.85 per side. The tool shows the notional it used so the percentage is easy to check.

Minimum and maximum commission are never applied silently. Many brokers floor the commission at a small minimum; some cap it. The tool applies these only when you enter them, and shows the calculated figure beside the applied one so you can see exactly when a floor or cap changed the result.

Commission may be quoted in another currency. Where the rate is not in your account currency, it has to be converted, and the rate needed is a live market number this page will not invent. Enter it, and until you do, the account-currency figure is withheld rather than guessed.

Commission in pips is a break-even figure, not a target. Dividing the commission by the pip value shows how far price must move just to cover it — $7 at $10 a pip is 0.7 pips. It is arithmetic on your cost, not a suggestion to trade or a promise about the market.

None of this is financial advice. No broker, account type or trade is recommended, and no cost level is called good or bad. The tool works out what a set of numbers comes to — the judgement stays with you.

What This Calculator Does

And, just as importantly, what it refuses to assume.

Every commission model

Per lot, per side, round-trip, percentage, per unit and fixed, each with its own formula, so the total matches your broker rather than a guess.

Round-trip never doubled

A round-trip rate is charged once; a per-side rate is multiplied by two. The most common commission mistake is designed out.

Minimums and caps, shown

Broker floors and caps are applied only when you enter them, with the calculated figure shown beside the applied one.

Into the whole cost

Fold commission together with spread and swap for a total trading cost and a net P&L, with credits handled correctly.

Across trades and sizes

Commission by lot size, a model comparison on one position, and a running total across several trades.

About the Forex Commission Calculator

Commission is the cost that a tight spread hides. On a raw- or ECN-style account the spread can be a fraction of a pip, and the broker earns instead through a commission charged on each trade. For anyone comparing account types, or trading often enough that the fees add up, knowing exactly what that commission comes to matters more than the headline spread.

The trouble is that brokers quote commission in several different ways, and they are easy to confuse. A rate can be per lot or per unit, charged per side or as a single round-trip figure, set as a percentage of the trade value, or applied as a flat fee. The same position runs to very different totals depending on which of those it is.

This calculator runs each model on its own path. A per-side rate is multiplied by two sides; a round-trip rate is charged once and never doubled; a percentage is taken from the notional value, which is units times price and therefore large. Getting these straight is the whole point, because doubling a round-trip figure, or forgetting to multiply a per-side one, is the most common commission error there is.

It also handles the details brokers actually apply. A minimum commission floors the charge on small trades; a maximum can cap it on large ones. Both are applied only when you enter them, with the calculated figure shown beside the applied one, so you can see the moment a floor or a cap changes the number. Where commission is quoted in another currency, it asks for a conversion rate rather than inventing one.

From that one figure the rest follows. Commission per lot, effective commission as a percentage of notional, and commission expressed in pips, which is the break-even move it represents. Then the wider picture: commission alongside spread and swap, a total trading cost, a net P&L after everything, a comparison of every model on the same position, and a running total across several trades.

What the tool does not do is assume a broker's structure, recommend an account type, or treat a break-even figure as a target. It works out what your numbers come to under the model you chose, shows entry and exit separately, and shows its working.

Frequently Asked Questions

The questions that come up most often about forex commission.

Commission is a fee your broker charges for executing a trade, separate from the spread. It is common on raw- or ECN-style accounts, where the spread is tight and the broker earns from a commission instead. It is usually quoted per lot, often per side so both entry and exit are charged, but some brokers use a round-trip rate, a percentage of the trade value, or a fixed fee. This calculator supports each of those models.

A per-side rate is charged once on entry and again on exit, so the total is the rate times your lots times two sides. A round-trip rate already covers both entry and exit, so it is charged once on your lots and never doubled. A "$3.50 per side" and a "$7 round-trip" come to the same total on one lot, and the mistake is doubling the round-trip figure as well, which this tool avoids by running each model separately.

It is a percentage of the notional value of the trade, not of your profit. Notional value is the number of units times the price, so one standard lot of EUR/USD at 1.10 is a $110,000 position. A 0.0035% per-side commission on that is about $3.85 per side, or $7.70 round-trip. Because notional is large, even a tiny percentage becomes a real figure, so the tool shows the notional it used so you can check it.

Whichever has the lower total, and you can only see that once both costs are in the same unit. Turn the commission into pips by dividing the round-trip figure by your pip value, then add it to the raw spread. That gives one number you can hold against the standard account's spread. At $3.50 a side on a standard lot of EUR/USD, the commission is 0.70 pips, so a raw account quoting 0.1 pips costs the same as a commission-free account quoting 0.8. Wider than that and raw wins; tighter and it does not. The table above does this at four common rates.

It is free of commission, which is not the same as free. The cost has moved into the spread, and whether that is a good trade depends entirely on how much wider the spread became. Brokers offering both account types are not running a charity on one of them; they are pricing the same service two ways and letting you pick the shape you prefer. Compare the totals in pips and the question answers itself, usually with a smaller difference than the marketing suggests.

A great deal more, and for the same reason spread does. Commission is charged per trade, so it scales with how often you trade rather than with how well. A round trip costing 0.7 pips is a rounding error against a two-hundred-pip swing and a fifth of a five-pip scalp. If you trade rarely and hold long, focus on execution and swap instead. If you trade often, commission may be the largest single line in your costs, and the difference between $2 and $7 a side is worth more attention than most entry techniques.

Some brokers floor the commission at a small minimum, $2 for example, so that very small trades are not charged a trivial amount. If your calculated commission comes to $1.20 but the minimum is $2, the applied commission is $2. This tool only applies a minimum (or a maximum cap) when you enter one, and shows the calculated figure beside the applied one so you can see exactly when the floor changed the result.

Divide the total commission by the pip value of your position. A $7 commission at $10 a pip is 0.7 pips, which means price has to move 0.7 pips in your favour just to cover the commission before any profit. It is a useful way to compare a commission account against a wider-spread, commission-free one, but it is a break-even figure, not a target or a trading recommendation.

Then it has to be converted. Enter the conversion rate from the commission currency to your account currency and the tool applies it. It will not use a live rate silently. If the rate is missing, it withholds the account-currency figure and tells you a rate is required, rather than showing a misleading number.

Commission is only one of the costs of a trade. The Commission + Spread, Commission + Swap and Net Cost tabs let you fold them together so you can see the full picture: spread plus commission plus swap plus any other costs, and a net P&L after all of them. A swap credit is handled correctly, reducing the total rather than adding to it.

No. The commission sum uses only the rate and volume you type, and it runs in this tab.
