Profit & Loss Calculator — Forex, Stocks & Crypto
Trading profit or loss comes from the signed price movement multiplied by quantity, with costs then deducted. Use the instrument’s contract units and the account currency consistently. Actual bid/ask entry and exit fills already reflect spread: subtracting it again double-counts the cost. For JPY pairs choose a 0.01 pip size and supply the correct USD pip value. Cross-currency conversion can change over the holding period. Funding, swap and taxes require separate treatment if not included in the fee input.

Why Use the Profit / Loss Calculator?
Trading profit or loss comes from the signed price movement multiplied by quantity, with costs then deducted. Use the instrument’s contract units and the account currency consistently. Compare the displayed result with the worked example and confirm the assumptions before using it.
Formula Used
Gross P&L = signed price movement × quantity; forex P&L = signed pips × USD pip value × lots; net = gross − total feesWorked Example
Buy 0.5 standard EUR/USD lots at 1.1000 and sell at 1.1020: 20 pips × $10 × 0.5 = $100 gross. With $7 total round-trip commission, net P&L is $93. A short opened at 1.1020 and closed at 1.1000 has the same gross profit.
