Our free Forex profit and loss calculator lets you estimate the outcome of a trade before you enter it. Select a currency pair, enter your lot size and entry/exit prices to see your potential profit or loss in USD.
What is a Profit/Loss Calculator?
A profit/loss (P&L) calculator estimates how much money you stand to gain or lose on a trade based on the price movement, lot size, and trade direction (buy or sell). It removes guesswork and helps you plan trades with clear risk/reward expectations. Professional traders always calculate potential P&L before entering a position.
How to Calculate Forex Profit and Loss
Select the currency pair, choose buy or sell, enter your lot size, entry price and exit price. The calculator computes the price difference, converts it to pips, and multiplies by the pip value to give you the profit or loss in USD. It also shows the number of pips gained or lost and the pip value per lot.
P/L = (Exit - Entry) × Lot × Contract Size
Profit/Loss Calculation Examples
Example: You buy 1 lot of EUR/USD at 1.0850 and sell at 1.0900. The difference is 50 pips. With a pip value of $10, your profit is $500. If price drops to 1.0800, you lose 50 pips = $500. Knowing this before the trade helps you set realistic targets and stop losses.
Why Use a Profit/Loss Calculator?
Estimating P&L before trading helps you set proper stop losses and take profits, evaluate risk/reward ratios, and avoid overleveraging. It is an essential part of every trading plan. Combined with a lot size calculator, it gives you complete control over your risk management.
