Position Size Calculator
Find the exact number of shares or lots to buy based on your capital and risk tolerance.
Position sizing ensures no single trade can cause catastrophic damage to your account. The 1% Rule is the standard — never risk more than 1% of capital on one trade.
Stop Distance = Entry − Stop Loss
Shares = Risk Amount ÷ Stop Distance
Example: ₹5,00,000 capital at 1% risk = ₹5,000 max loss. Entry ₹1,000, Stop ₹950 (₹50 distance). Shares = ₹5,000 ÷ ₹50 = 100 shares.
Position sizing is the single most important risk management skill in trading — more critical than your entry strategy. The Position Size Calculator helps NSE traders determine exactly how many shares or futures lots to buy based on their account size, risk tolerance, entry price, and stop loss level. Without proper position sizing, even a winning strategy can blow up an account during a losing streak. The standard rule used by professional traders is the 1% Rule — never risk more than 1% of your total capital on a single trade. This means a trader with ₹5,00,000 capital risks a maximum of ₹5,000 per trade regardless of how confident they feel about the setup. Applied consistently across hundreds of trades, the 1% rule ensures that even a run of 10 consecutive losses only drawdown the account by 10% — fully recoverable. On NSE, position sizing applies equally to equity delivery trades, intraday MIS trades, NIFTY futures, and BANK NIFTY options. The formula automatically adjusts the number of shares based on the distance between your entry price and stop loss — wider stops mean fewer shares, tighter stops mean more shares, but the rupee risk per trade stays constant.
