Stop Loss Calculator

Summary

Enter your entry price, account size, and risk tolerance to calculate the ideal stop loss price and position size for any trade.

How it works

1. Enter your total account size in dollars.
2. Set the maximum percentage of your account you are willing to risk on this trade (e.g. 1%).
3. Enter the entry price — the price at which you plan to open the position.
4. Choose whether to define your stop loss as a percentage below entry or as a fixed stop price.
5. The calculator instantly shows your stop loss price, position size (shares/units), and maximum dollar risk.
