What this tool does
The Profit / Loss Calculator projects what a trade will make or lose given an entry price, an exit price, and a position size. It works for both long positions (profit when price rises) and short positions (profit when price falls), and converts the result into your account currency. Some versions also subtract the spread or commission so the figure is closer to reality.
Traders use it in two ways: before entering, to check whether a planned take-profit is actually worth the risk; and after closing, to review what a trade really earned once costs are included. Seeing the numbers in advance removes a lot of wishful thinking — a "200 pip winner" sounds great until you discover it was only worth $40 on your position size.
How to use it
- Choose whether the trade is long (buy) or short (sell).
- Enter your entry price and your planned exit price (or take-profit level).
- Enter the position size in lots or units.
- Add the spread or commission if you want a net figure.
- Read the projected profit or loss in your account currency.
- Compare it with your planned risk to check the reward-to-risk ratio makes sense to you.
