Total Trade Cost Calculator
Add the spread, adverse slippage, commission, financing and other costs you enter for one position. Pip-derived charges use the shared Pip Pricing model; the page does not fetch or rank broker fees.
Enter one position and its costs
Use one account currency and enter zero explicitly when a component does not apply.
Supplies the stored pip size, contract size and quote currency.
All entered monetary costs must use this currency.
Enter the quantity in the selected lot type; broker volume limits are not checked.
The multiplier applied to the stored standard contract size.
The required conversion direction appears here.
Enter the total spread amount assigned to the complete modeled trade. It is not doubled automatically.
A non-negative scenario input, not a predicted fill difference.
Enter the adverse exit difference you want to model.
Enter an account-currency amount quoted per standard-lot equivalent per charged side.
The tool does not infer whether the broker quote is one-way or round-turn.
Enter the whole holding-period amount: positive for a charge, negative for a credit.
A non-negative account-currency amount for other charges you choose to include.

How the total is calculated
The shared pip-pricing model first converts one pip for the entire position into the selected account currency. Spread and adverse slippage pips are multiplied by that value. Commission is scaled by the standard-lot equivalent and the one- or two-side setting. Entered financing and other costs are then added.
Cost-equivalent pips divide the final entered cost by the position pip value. That is an arithmetic translation of the entered cost stack, not a predicted fill or required market movement.
Worked entered-cost example
| Input | Example | Contribution |
|---|---|---|
| EUR/USD position pip value | USD 10 per pip | Used for spread and slippage |
| Spread | 1.2 pips | USD 12 |
| Entry + exit slippage | 0.1 + 0.2 pips | USD 3 |
| Commission | USD 3.50 x 1 standard lot x 2 sides | USD 7 |
| Financing + other | USD 2 + USD 1 | USD 3 |
| Total | USD 12 + 3 + 7 + 3 | USD 25, or 2.5 pips |
Assumptions and limits
- Every cost is entered by the user. The tool does not fetch broker spreads, commission schedules, swap rates, rebates or execution data.
- Spread is the total spread amount assigned to the modeled trade and is not doubled automatically.
- Slippage fields accept adverse non-negative scenarios only; they do not predict execution.
- A negative financing entry is treated as a credit. A negative final total means the entered credit exceeds the entered charges, not that the trade is profitable.
- Instrument metadata and manual conversion rates can differ from the exact broker symbol and account rules.
- Taxes, changing spreads, partial fills, latency, gaps, rebates and unentered charges remain outside the result.
Frequently asked questions
- The calculator includes entered spread, adverse entry and exit slippage, commission per standard lot per charged side, financing charge or credit, and one other-cost amount.
- The bid and ask differ by the spread. Investor.gov describes that difference as an inherent trading cost, separate from any commissions or other transaction charges.
- No. Enter the total spread pips you want assigned to the complete modeled trade. The model multiplies that entry once by the position pip value.
- Commission equals the entered account-currency amount per standard lot per side, multiplied by the standard-lot equivalent of the position and either one or two charged sides.
- It is an adverse entry or exit difference in pips that you choose to model. The page does not estimate future slippage or read execution records.
- Yes. Enter a financing charge as positive and a credit as negative. A credit can offset entered charges but does not establish the overall profitability of a trade.
- Spread and slippage are derived from the position pip value. When the pair quote currency differs from the account currency, a manual conversion rate is required in the direction stated beside the field.
- Only if the entered costs, conversion and instrument specification match the broker account and execution being modeled. Verify the broker's contract and fee schedule independently.
