That sounds contradictory until you add commission. Then add trade size. Then multiply everything by the number of trades you make each month.
Suddenly, comparing forex accounts becomes much less straightforward than simply looking for the smallest spread on a broker’s website.
That is exactly the problem the Broker Account Cost Calculator was built to solve.
The free tool from FOREXSIGNAL24 lets traders model spread and commission costs across different broker account types using the same trading scenario, making it easier to see how account pricing can change the estimated cost of trading.

Why Comparing Forex Account Costs Is Harder Than It Looks
Most brokers offer more than one account type. One account may have wider spreads and no trading commission. Another may advertise raw spreads or spreads from 0.0 pips while charging commission per lot per side.
A third account may combine a slightly wider spread with a lower commission. Looking at those numbers separately does not always tell you which structure produces the lower transaction cost for the way you trade.
Consider two simplified examples:
- Account A: 0.8 pip spread, no commission.
- Account B: 0.1 pip spread, $3.50 commission per lot per side.
Account B clearly has the tighter spread. But that does not automatically mean it has the lower total cost. Commission has to be added to spread cost before the comparison becomes meaningful.
What Is the Broker Account Cost Calculator?
The Broker Account Cost Calculator is a browser-based forex tool designed to estimate transaction costs across different broker account types.
Instead of comparing one broker’s headline numbers in isolation, the calculator applies a common scenario across the accounts being analyzed.
You can set:
- broker or comparison scope;
- trading instrument;
- lot size per trade;
- number of trades per month;
- pip value.
The tool then combines spread assumptions and round-turn commission for each account row that contains enough data to be calculated.
The current dataset covers broker groups including Exness, HFM, Tickmill, XM, FBS, IC, RoboForex, AvaTrade, easyMarkets, Headway, InstaForex, TMGM, FirewoodFX and Elev8.
How the Calculation Works
1. Spread Cost
The calculator estimates spread cost using:
Spread in pips × pip value per lot × traded lots
For example, assume EUR/USD, 1.00 lot, a pip value of $10 and a spread of 0.5 pip. The estimated spread cost is:
0.5 × $10 × 1 = $5
2. Commission Cost
Commission is calculated on a round-turn basis. If a broker charges $3 per lot per side:
$3 × 2 × 1 lot = $6
The per-side commission is multiplied by two because a completed trade normally includes both opening and closing transactions.
3. Estimated Total Trading Cost
The estimated transaction cost becomes:
Spread cost + round-turn commission
Using the example above, $5 of spread cost plus $6 of commission produces an estimated $11 per completed 1-lot trade.
If the trader completes 20 similar trades during the month, the modeled monthly transaction cost becomes $220.
This is where the calculator becomes especially useful: a small difference per trade can become meaningful when multiplied across dozens or hundreds of transactions.
A Practical Example: Comparing Exness Account Types
One useful way to understand the calculator is to compare several account structures under the exact same assumptions.
Suppose the scenario is EUR/USD, 1.00 lot per trade, 20 trades per month and a $10 pip value.
Using the current reference assumptions inside the calculator, the modeled monthly costs for Exness can differ significantly between Standard, Pro, Zero and Raw Spread accounts.
For example, a 0.2-pip spread with no commission models at roughly $2 per lot, or about $40 for 20 lots of monthly trading volume. A 0.1-pip spread with no commission models at roughly $1 per lot, or about $20 per month.
A zero-spread account has to be evaluated differently because commission becomes a larger part of the transaction cost. That is why looking only at “spread from 0 pips” can be misleading.
What “Lowest Modeled Cost” Actually Means
The calculator highlights the Lowest Modeled Cost among rows that contain enough information to be calculated.
That does not mean best broker, best account for every trader, cheapest broker under all market conditions or guaranteed live trading cost.
It simply means that under the assumptions currently entered into the calculator, that completed row produces the lowest modeled transaction cost.
Change the spread, commission, lot size or number of monthly trades and the result can change too.
This makes the tool more useful as a scenario analyzer than as a static broker ranking system.
Published Baselines vs Live Trading Conditions
Forex spreads are not fixed in many account structures. They can change according to liquidity, volatility, time of day, economic news, instrument, broker entity, account type and platform.
For that reason, the calculator does not present its default values as live executable quotes.
Where possible, broker-published pricing is used as a reference baseline. More importantly, spread and commission fields remain editable.
If your MT4, MT5, cTrader, TradingView or broker platform currently shows a different value, you can replace the reference assumption with the current figure and the model recalculates immediately.
Why Some Accounts Say “Manual Input Needed”
Some broker pricing cannot be safely normalized into one universal spread-and-commission format.
One broker might quote commission as $3.50 per lot per side, while another publishes commission based on USD notional turnover per $1 million traded. Those are not automatically interchangeable.
Likewise, some brokers publish symbol-level spreads rather than one account-wide figure. In those cases, the calculator leaves uncertain fields blank instead of creating false precision.
Special Handling for XAU/USD
Gold is another area where trading-cost comparisons can easily go wrong.
A forex pip convention cannot simply be copied into XAU/USD because contract sizes, point values, spreads and commissions can differ.
The calculator therefore uses an XAU/USD safety mode. Forex account-level spreads are not automatically reused for gold. Only verified instrument-specific values may be prefilled; otherwise the trader is asked to enter the current XAU/USD spread.
What Costs Are Not Included?
The calculator focuses primarily on transaction costs from spread and trading commission.
Depending on the broker and instrument, traders may also face overnight swap or financing, currency-conversion fees, slippage, widened spreads during volatile markets, inactivity fees, taxes or local charges.
The result should therefore be treated as an estimated transaction-cost model, not a final account statement.
Who Can Benefit Most From This Tool?
Scalpers
Traders completing many trades per day can be highly sensitive to small differences in spread and commission. A few dollars per round turn can become significant over a large monthly trade count.
Day Traders
Day traders can use the calculator to compare commission-based and spread-only accounts before choosing an account structure.
EA and Algorithmic Traders
Automated strategies often generate relatively consistent trading volume, making monthly cost modeling useful when testing how execution costs may affect a strategy.
Traders Comparing Brokers
If you are already researching brokers on ForexReview.top, the calculator adds another layer to the analysis. Broker reviews help you assess support, platform features, withdrawals, spreads and account availability. The calculator then helps translate selected pricing assumptions into an estimated cost under your own trading volume.
How to Use the Broker Account Cost Calculator
- Choose a broker. Select one broker or compare all supported broker groups.
- Select the instrument. Choose a forex preset such as EUR/USD or GBP/USD, XAU/USD, or a custom instrument.
- Enter your trade size. Set the lot size you normally trade.
- Enter your monthly trade count. This converts per-trade cost into a monthly estimate.
- Check the pip value. Adjust it when the instrument or account currency requires a different value.
- Review the comparison. The tool shows cost per lot, cost per trade, monthly cost, annualized cost and relative modeled cost.
- Replace baselines with current values. If your broker platform shows a different spread or commission, enter it for a more relevant scenario.
Broker Research Should Go Beyond the Headline Spread
“Spreads from 0.0 pips” can be useful information, but it is not enough by itself.
The more practical question is: What does this account cost under the way I actually trade?
That requires looking at spread and commission together and applying the same trade size and frequency to every account being compared.
The Broker Account Cost Calculator will not tell you which broker you should choose. What it can do is help you compare one important part of the decision with clearer and more consistent assumptions.
