Formula & calculation method
For Buy, estimated profit or loss = (exit price − entry price) × base units × quote-to-account conversion rate. Reverse the sign for Sell. Results exclude spreads, commissions, swaps, and slippage.
Input reference · 5 fields
These labels describe the calculation’s base units. Supported measurements can switch through the header’s region settings; follow the current workspace labels. Prefilled values are examples.
- Trade direction
- Choose Buy for long or Sell for short.
- Entry price
- Use the price at which the position opens.
- Exit price
- Use an assumed or actual closing price.
- Position size (base-currency units)
- 0.10 of a 100,000-unit standard lot = 10,000 units.
- 1 quote-currency unit in account currency
- Use 1 when the quote currency is your account currency.
A quick example
Buying 10,000 EUR/USD units at 1.1000 and exiting at 1.1050 produces USD 50 before costs.
Assumptions, edge cases & limits
- Educational estimate. Excludes spreads, commissions, swaps, slippage, and broker-specific margin tiers. A stop loss does not guarantee the exit price. Verify contract sizes and rates with your broker.
- Enter base-currency units rather than a lot count, and use the quote-to-account conversion direction.
Questions about Forex Profit / Loss Calculator
Does the P/L estimate include spread, swap and commission?
No. It uses the price difference, base units, direction and your currency-conversion assumption. Add applicable trading costs and verify actual execution prices separately.
Should I enter lots or base-currency units?
Enter units. For a 100,000-unit standard FX contract, 0.10 lot equals 10,000 units. Broker and instrument contract specifications can differ, so verify that conversion.
Are my files or inputs uploaded?
Calculation and file processing run in your browser without a processing upload. Downloads go to your device. Choosing a next-step transfer creates a temporary local copy for that workflow. Region preferences are stored separately from tool inputs. See our privacy details.
Can I use this tool for free?
Yes. No signup, subscription or payment is required to use the tool or download its output. File tools have device and size limits; a smaller batch may work better on a phone.
