Profit/Loss Calculator
Calculate your trade P&L with spread factored in. Enter entry and exit prices to see profit or loss in dollars and pips.
How is Forex Profit Calculated?
Forex profit or loss is calculated by multiplying the number of pips gained or lost by the pip value and lot size. For a buy trade, profit = (exit price - entry price) / pip size × pip value × lots.
Don't forget to factor in the spread — your broker's fee per trade. This calculator subtracts the spread cost from your gross P&L to show you the true net result.
Common questions
How do you calculate profit on a forex trade?
Multiply the move in pips by the pip value of your position size, then subtract costs. A 40-pip win on 0.5 standard lots of EUR/USD is 40 x $5 = $200 gross, less spread, commission and any swap held overnight.
Does the spread come out of my profit?
Yes, and it is charged the moment you enter. You buy at the ask and sell at the bid, so a 1-pip spread means the trade starts one pip underwater. Strategies that trade often are affected far more by this than strategies that hold for days.
What is a realistic commission to assume?
On a raw-spread account, roughly $3.50 per side per standard lot, so $7 round trip. That is the figure used in every backtest published on this site. Standard accounts usually bundle the cost into a wider spread instead.
When is swap charged?
On positions held past the broker's daily rollover, typically 5pm New York time, with a triple charge on Wednesday to cover the weekend. Swap can be positive or negative, and on multi-day strategies it often matters more than the spread.
Where we use this
We compute P&L net of spread, commission and swap in every published test. Most backtests skip that.
