Position Sizing
The calculator determines your position size based on your risk percentage and the distance between your entry and stop loss.
Risk Management
Never risk more than 1-3% of your account on a single trade. This calculator helps you maintain proper risk management.
Risk-Reward Ratio
Aim for a risk-reward ratio of at least 1:2. This means your potential profit should be at least twice your potential loss.
Margin Requirements
The margin required shows how much of your account balance will be used as collateral for the trade.
Calculate position size, risk amount, potential profit and risk-reward ratio before you enter a trade. Enter your account size, risk percentage, entry, stop-loss and take-profit — the calculator does the rest.
How to use this tool
- Enter account size and risk. Type your account balance and the percentage you are willing to risk on the trade (commonly 1–2%).
- Set entry, stop-loss and take-profit. These three prices define your risk per unit and your reward target.
- Read the results. The tool outputs the position size, the dollar amount at risk, potential profit and the risk-reward ratio.
