Position Size Calculator
About This Calculator
The Position Size Calculator helps traders determine exactly how many units of an asset to buy based on their account size, risk tolerance, and stop-loss level. Proper position sizing is the foundation of risk management and long-term trading success.
How It Works
- Account Size: Total capital available for trading
- Risk Per Trade: Percentage of capital you're willing to lose (typically 1-2%)
- Entry Price: Price at which you plan to enter the trade
- Stop Loss: Price at which you'll exit to limit losses
- Formula: Position Size = (Account × Risk%) / (Entry - Stop Loss)
Risk Management Rules
- Never risk more than 1-2% of your account per trade
- Set stop-loss before entering any position
- Adjust position size based on setup quality
- Account for fees and slippage in calculations
