A Forex Broker Commission Calculator helps traders estimate how much a broker charges for opening and closing forex positions. It calculates commission based on trade size and the broker's published commission rate, helping traders understand the direct cost of a trade before placing an order.
If you are comparing brokers, you can also explore the trading conditions offered by FBS. FBS currently lists no trading commission on its general trading conditions page, alongside floating spreads from 0.7 pips. This makes it a useful example when comparing commission-based pricing with spread-based pricing. Actual conditions depend on the instrument, account, and applicable terms. (FBS trading conditions)
A calculator can help answer practical questions:
The important point is that commission is only one component of total trading cost. Spreads, overnight financing, currency conversion, and other applicable charges may also affect the final amount.
A forex commission calculator uses three main inputs:
The standard formula is:
Commission = Trade volume × Commission rate × Number of charged sides
For example, assume a broker charges $3.50 per standard lot per side. A trader opens and closes a 1.00-lot position.
Commission calculation:
Total commission:
1.00 × $3.50 × 2 = $7.00
The estimated round-turn commission is $7, excluding spreads and other costs.
Always check whether the broker quotes commission per side or round turn. If the published rate already includes opening and closing, multiplying it by two would overestimate the cost.
The following examples assume a commission of $3.50 per standard lot per side, charged on both opening and closing. These figures are illustrative, not the rates of a specific broker.

These calculations assume that commission scales proportionally with trade size and that no minimum charge or alternative rounding rule applies.
The table demonstrates why trade volume matters. At the same commission rate, a 1.00-lot position incurs ten times the commission of a 0.10-lot position.
Understanding commission terminology is essential when comparing forex brokers.
Per-side commission refers to the charge for one part of a trade, usually opening or closing a position.
Round-turn commission refers to the combined commission for opening and closing the position.
For example, suppose a broker advertises a $3 commission per lot per side. A completed 0.50-lot trade would incur:
Opening commission: 0.50 × $3 = $1.50
Closing commission: 0.50 × $3 = $1.50
Total round-turn commission: $3.00
However, if another broker advertises $6 per lot round turn, a 0.50-lot trade would also cost $3 in commission.
The pricing descriptions differ, but the calculated commission is the same.
Before entering a rate into your calculator, confirm the unit, currency, and charging method.
Forex brokers commonly use different pricing structures. Some charge an explicit commission alongside a relatively tight spread, while others offer commission-free trading with the spread forming a key part of the trading cost.
A spread is the difference between the bid price and ask price. A commission is a separate trading charge that may be applied when opening or closing a position.
For example, a commission-based account might advertise a 0.2-pip spread plus a $7 round-turn commission per standard lot. A commission-free account might advertise a wider spread but no separate trading commission.
Neither pricing model is automatically cheaper. You need to calculate the combined cost for your actual trade size.
For more detail on how spreads work, see the FBS explanation of spreads.
A commission calculator answers only part of the cost question. To compare brokers accurately, calculate the spread cost and commission together.
For a standard lot of EUR/USD in a USD-denominated account, a commonly used approximation is that one pip is worth $10. The actual pip value depends on the instrument, position size, and account currency.
The estimated formula is:
Total trading cost = Spread cost + Commission
Where:
Spread cost = Spread in pips × Pip value per lot × Trade volume
Consider an illustrative example:
Spread cost:
0.20 × $10 × 1.00 = $2
Total estimated cost:
$2 + $7 = $9
The estimated cost for completing the trade is $9, excluding overnight financing and other applicable charges.
The example assumes the stated spread represents the spread cost to be included once in the completed trade. Actual costs may differ due to execution, changing spreads, and broker-specific pricing conventions.
Use the same instrument, trade size, and holding period when comparing accounts. Otherwise, you may end up comparing different costs rather than different pricing models.

For a fair comparison, obtain the broker's current spread and commission for the instrument you plan to trade.
Assume the following hypothetical conditions for a 1.00-lot EUR/USD round trip:
Broker A
Broker B
Under these assumptions, Broker A has the lower estimated cost by $1.
However, if the spread at Broker A widens or the commission structure differs, the result may change. Always use realistic spreads rather than relying solely on advertised minimums.
FBS currently states on its general trading conditions page that it does not charge a trading commission and advertises floating spreads from 0.7 pips. It also lists a minimum order volume of 0.01 lots. (FBS trading conditions)
For traders evaluating FBS, the key distinction is between a separate commission and the other costs of trading.
A zero-commission statement does not mean that trading is cost-free. Spreads remain relevant, and swap charges or other applicable fees may affect a position depending on the instrument, account conditions, and holding period.
Before opening an account, check the current conditions for your specific instrument. The FBS forex specifications page provides instrument-level information, including spread and swap data.
A commission calculator can also help estimate trading expenses over a month.
Use this formula:
Monthly commission = Commission per round turn × Lots per trade × Number of completed round turns
For example, suppose a trader completes 40 round-turn trades per month, each at 0.10 lots, with an illustrative round-turn commission of $7 per standard lot.
Commission per trade:
$7 × 0.10 = $0.70
Monthly commission:
$0.70 × 40 = $28
This estimate covers commission only. It does not include spreads, overnight financing, slippage, or currency conversion.
A trader who completes many transactions may find that total trading costs materially affect strategy performance. Calculating these expenses in advance can help with budgeting and broker comparisons.
If the broker already quotes commission for opening and closing, do not multiply the rate by two again.
A rate quoted per standard lot must be scaled to the actual position size.
A zero-commission account can still have a meaningful spread cost.
The minimum spread may not reflect the spread you receive during your trading sessions.
Positions held overnight may incur swap or financing costs, depending on the instrument and account terms.
If commission is charged in a different currency from your account, conversion may affect the final amount.
A commission rate for one asset may not apply to another. Confirm the broker's specifications for each instrument.
A forex broker commission calculator estimates commission using the trade volume, commission rate, and number of charged sides. It can help traders compare broker costs before opening positions.
Multiply the number of lots by the commission rate. If the broker charges per side, multiply by two for a completed opening-and-closing trade, assuming both sides are charged at the same rate.
There is no universal commission rate. Some accounts charge commission per lot, while others use a commission-free structure with spreads. Rates depend on the broker, account type, instrument, and jurisdiction.
Round-turn commission is the combined commission for opening and closing a position. Always confirm whether the broker's published rate is per side or round turn.
Not necessarily. A zero-commission account may have a wider spread. Compare the spread cost and any other applicable fees to determine which option is cheaper for your trading volume.
FBS currently lists no trading commission on its general trading conditions page. Traders should still account for spreads, financing, and any other applicable costs. Check the current conditions for the relevant account and instrument.
A basic commission calculator may calculate only the separate commission. A full trading-cost calculator should also account for spread, and where relevant, overnight financing, conversion costs, and other charges.
Multiply the commission per completed trade by your typical trade size and the number of completed round turns. Then add estimated spread costs and any other relevant charges.
A Forex Broker Commission Calculator helps traders estimate commission per lot, understand round-turn charges, and compare account pricing structures. But the most useful comparison includes the spread and other costs, not commission alone.
Before choosing a broker, confirm:
FBS currently lists no trading commission in its general trading conditions, with floating spreads from 0.7 pips. That makes it a relevant example of a spread-based pricing structure, but it does not establish that every trade will be cheaper than a commission-based alternative.
The best approach is to calculate the total estimated cost using the conditions that apply to your actual trading activity.
