How the P&L calculation works
For a long trade, gross P&L is (exit price − entry price) × quantity × contract multiplier. A short reverses the price difference because it profits when the exit is below the entry. Net P&L subtracts the total fees you enter. The percentage result divides net P&L by the position’s entry notional, so leverage is not mistaken for investment return.
For example, buying 10,000 units at 1.0850 and closing at 1.0925 creates a 0.0075 price move. With a multiplier of one, gross P&L is $75. If commissions and other entered costs total $4, net P&L is $71. The arithmetic is simple; using the correct quantity, multiplier and account-currency conversion is the part that needs attention.
What the calculator deliberately does not assume
Contract rules differ across brokers and instruments, so this tool does not guess pip value, lot size, funding, swap, tax or currency conversion. A forex account whose quote currency differs from the account currency may need a conversion after the result. CFDs may use a contract multiplier. Check the broker specification and account statement rather than copying a default from another symbol.
Planned P&L and realised P&L answer different questions
Before entry, the result is a scenario based on a target or stop. After exit, it is a reconstruction of the trade. The difference between planned and realised P&L can reveal slippage, changed stops, partial exits and fees. Save those differences in a journal instead of treating the calculator as a one-off number.
Edgelog records realised results from MT4/MT5 sync, Binance and Bybit imports, or CSV and Excel files. Pair the result with the risk/reward calculator, then review actual performance in the P&L calendar. This calculator is educational and does not provide investment advice.
