THE METHOD · FOUR STEPS

How this Spread & Commission Calculator works

Follow the inputs, calculate the estimate and check the assumptions before making a trading decision.

  1. 01Set your inputs

    Enter the fields for your instrument, account and planned trade.

  2. 02Review specifications

    Check lot, contract, pip and conversion values where those fields appear.

  3. 03Calculate

    See the estimate and its breakdown in the results panel.

  4. 04Verify before trading

    Compare the assumptions with your broker’s current conditions.

Calculation and assumptions

Spread cost = spread in pips × pip value. Round-trip commission = commission per lot × lots. Total = spread cost + round-trip commission. If your broker quotes commission per side, double it before entering. Swaps and slippage are excluded.

Where a quote-to-account conversion field is available, enter how much one unit of the instrument’s quote currency is worth in your account currency. There is no automatic exchange-rate feed. Check contract sizes, volume limits, pip conventions and applicable charges in your broker’s symbol specifications.

These are estimates, not order instructions. Fees, spreads, slippage, price gaps and changing conversion rates can increase actual losses. Margin availability is not a safe position-size limit.

QUICK ANSWERS

Frequently asked questions

Does this include swaps and slippage?

No. The estimate adds spread cost and the round-trip commission you enter; other costs are excluded.

Are the example values live market data?

No. Inputs are editable examples, not live quotes or broker specifications. Check current prices and contract terms with your broker.

Can I use this estimate as an order instruction?

No. The tool is educational and does not place trades. Trading costs, conversion rates and price moves can change the actual result.
