Forex Trading Cost Calculator
Compare two account quotes using spread, commission per side, slippage and financing. All defaults are illustrative inputs, not live broker prices.
Compare the complete round trip
Total cost = lots × (spread × pip value per lot + 2 × commission per side + total slippage pips × pip value per lot) + total financing cost. The spread is counted once for a round trip. A per-side commission is counted twice. Financing is the total for the position and holding period, not a per-lot daily number. Enter credits as negative financing costs.
The default example produces A = 12 and B = 9 account-currency units, a difference of 3. These are sample prices. Replace them with comparable quotes from the same instrument, session and trade size. An advertised minimum spread is not an average spread.
How to use the result
The break-even move divides all entered costs by your position’s pip value. It is an approximation for a constant spread and conversion rate. Add expected order slippage once; do not also add slippage already captured in an executed-price P/L comparison.
Use financing estimates for overnight positions and read the broker comparison for entity and account checks.
Frequently asked questions
Is spread charged twice in this comparison?
No. The spread is included once for the round trip. Commission entered per side is counted twice. Do not add spread again when it is already represented by executed entry and exit prices.
Are these live broker prices?
No. The defaults are examples. Enter comparable spread and fee quotes for the same symbol, session, volume and holding period.
