Position Sizing Calculator

💡 Why use this calculator?

Many beginner investors focus only on potential gains without managing position sizes, which destroys accounts. Professional traders use the 2% Rule (Alexander Elder) or Kelly Criterion to practice money management that prevents ruin under any market condition.

This calculator includes trading commissions and securities transaction tax to compute real loss amounts, and analyzes your Risk Reward Ratio to objectively assess whether the trade setup is worth taking.
