Forex Net Profit and Loss Calculator
Estimate a long or short trade’s gross price result and net result after commission, extra costs and financing, in your chosen account currency.
From price change to account-currency profit
For a long position, gross P/L = (exit − entry) × contract size × lots × conversion. A short position reverses the price difference. Net P/L subtracts round-trip commission, any extra pip cost and the total financing cost. Negative financing is a credit.
With the illustrative EUR/USD inputs, a 50-pip rise on 0.10 lots gives USD 50 gross and USD 49.30 net after USD 0.70 commission. This is arithmetic, not a forecast or an achievable return claim.
Avoid double-counting
Actual entry and exit execution prices already reflect their bid/ask sides. Leave extra costs at zero unless you are modelling an additional spread or slippage allowance. The financing input applies to the whole position. For non-USD accounts use a current conversion from the quote currency; historical trades should use the conversion applicable at closure, not today’s reference rate.
Conversion reference: ECB daily reference rates.
Frequently asked questions
How is a short trade calculated?
The gross price difference is entry minus exit, multiplied by contract size, volume and conversion. Commission and entered costs are then deducted, while negative financing represents a credit.
Which conversion should I use for a historical trade?
Use the quote-to-account conversion relevant to the trade’s closing time. Today’s ECB reference is not a reconstruction of a historical conversion or the broker’s actual conversion charge.
