FREE FOREX COST CALCULATOR

The target is gross. What remains after costs?

Turn an entered spread, per-side commission and signed overnight swap into one transparent cash result. Add a stop and target to see how those costs change the planned R.

SPREAD + COMMISSION + SWAP

Price the whole fictional trade.

Supply the pip value yourself, then see each cash burden separately. This tool does not fetch rates, infer a contract or connect to a broker.

VERIFY EACH INPUT

Get the pip value first, then map costs into the trade.

Pip value depends on the symbol, lot size and account currency. Once that is checked, compare the cost result with the trade and margin geometry separately.
