What Is Position Sizing?

Position sizing answers the most important question before every trade: how many shares should I buy? The idea is straightforward. You decide the maximum percentage of your capital you are willing to lose on a single trade, then work backwards to find the exact quantity. Most professional swing traders risk 1-2% per trade. That means even 10 consecutive losing trades only draw down your account by 10-20%, leaving you with enough capital to recover.

The Position Sizing Formula

Shares = (Capital x Risk%) / |Entry Price - Stop Loss|

Example: You have ₹5,00,000 in capital and want to risk 2%. Your risk amount is ₹10,000. If you plan to enter at ₹1,500 with a stop loss at ₹1,450, the risk per share is ₹50. Dividing ₹10,000 by ₹50 gives you 200 shares (position value: ₹3,00,000, or 60% of capital).

Why Indian Trading Charges Change the Math

Most position size calculators ignore trading costs. In India, equity delivery trades attract STT at 0.1% on both buy and sell sides, stamp duty at 0.015%, GST at 18% on transaction charges, and SEBI turnover fees. Together, these push your real breakeven higher than your entry price. On a ₹3 lakh position, total charges can run ₹600-800. This calculator includes every charge so you see your actual risk and actual profit, not just the theoretical numbers.
