Quick answer
This broker fee calculator estimates four entered cost categories: spread, commission, overnight financing and other costs. It uses a simplified notional-based formula and updates in your browser as inputs change. Actual fees depend on the broker, product, account, currency, market conditions and contract terms. Use the current fee schedule for the exact account, and treat this output as a comparison aid rather than a prediction of a future charge.
Key takeaways
- Enter rates from the provider’s current fee schedule for the product and account you are comparing.
- The estimate separates spread, commission, financing and other costs rather than hiding them in one number.
- The calculator does not model variable quotes, minimums, taxes, slippage or every provider-specific rule.
- Compare like-for-like trade size, currency and holding period across providers.
Estimate Common Trading Costs
Enter non-negative amounts and percentages. This simplified tool assumes the spread is a percentage of notional value and financing is a straight-line annual rate divided by 365 days.
| Estimated spread cost | $5.00 |
|---|---|
| Estimated commission | $6.00 |
| Estimated financing | $1.10 |
| Estimated other entered costs | $0.00 |
| Estimated total | $12.10 |
Estimated total: $12.10
This calculator provides an estimate based on the values entered. Actual spreads, commissions, financing rates, conversion costs and other charges can vary by broker, product, account type and market conditions.
How the Broker Fee Calculator Works
The spread estimate equals notional value multiplied by the entered spread percentage. Commission equals the entered per-side amount multiplied by the number of sides. Financing equals notional value multiplied by the annual rate and holding nights, divided by 365. The “other entered costs” field lets you include a separate amount such as an estimated conversion or payment fee.
The selected currency controls how the entered values and results are displayed; it does not convert one currency into another. Enter all amounts in the same currency and use a consistent quote source.
What the Calculator Includes
| Category | Calculation | What to enter |
|---|---|---|
| Spread | Notional × spread percentage | A rate expressed as a percentage of notional |
| Commission | Per-side charge × number of sides | The fee shown for opening or closing |
| Financing | Notional × annual rate × nights ÷ 365 | An annualized rate and number of nights |
| Other entered costs | User-entered amount | A separate amount in the selected currency |
What It Does Not Include
The calculator does not automatically fetch broker prices or fee schedules. It does not model variable spreads, minimum commissions, tiered pricing, market-data subscriptions, taxes, exchange charges, slippage, changing financing rates, weekend rollover conventions or the precise contract multiplier for every product. It also does not account for gains, losses or investment performance.

Why Actual Trading Costs Can Differ
Prices and fees can change between the time you estimate and the time an order is executed. A provider may use a different contract size, day-count convention, rollover time or account-specific rate. A payment processor or bank may apply its own charge. The stated spread may also be indicative rather than fixed.
Before using an estimate, compare the order size and product with the broker’s product specification and fee schedule. Review both opening and closing costs, then confirm whether the estimate includes the same currency and holding period as the account you are considering.
How to Find a Broker’s Real Fee Schedule
- Identify the legal entity and account type you would use.
- Open that entity’s current fee schedule and product specifications.
- Check spread, commission, financing, conversion, payment and account charges.
- Confirm minimums, effective dates, exceptions and any rate that can vary.
- Contact the provider if a term is unclear, and save the current disclosure.
