Forex Lot Size Calculator
What is this tool?
A forex position sizing calculator that converts your account risk parameters into a recommended lot size. Instead of picking a trade size arbitrarily, you define how much of your account you're willing to risk on a single trade, and the calculator works backward to a position size.
When to use it
- Sizing a new trade before entering the market
- Standardizing risk per trade across a trading plan
- Comparing how different stop-loss distances change the required lot size
- Checking position size after an account balance change
- Reviewing risk consistency across multiple currency pairs
How to use it
- 1Enter your account balance and the percentage of the account you want to risk on this trade.
- 2Enter your stop-loss distance in pips and select the relevant currency pair, if applicable.
- 3The tool calculates the recommended position size (lot size) instantly.
- 4Adjust any input to see the position size update in real time.
Frequently asked questions
Does this calculator guarantee I won't lose more than my risk percentage?
No. It calculates a suggested position size based on your inputs, but actual losses can differ due to slippage, gaps, or broker execution. It is not a guarantee.
Do I need to know pip values to use this tool?
The calculator handles the pip-value math internally based on the inputs you provide; you mainly need your account balance, risk tolerance, and stop-loss distance.
Is this financial or trading advice?
No. This tool is for informational and educational purposes only. Forex trading involves substantial risk, and you should consult a licensed professional before trading.
Is my account information stored anywhere?
No. All calculations happen locally in your browser and are never saved or sent to a server.
