What is the Position Size Calculator?
Position sizing — deciding how many shares or contracts to trade — is one of the most underrated skills in trading. Even a trader who picks winning trades most of the time can blow up an account by risking too much on a single position; disciplined position sizing caps the damage from any one trade going wrong, which matters far more to long-term survival than being right more often.
How to Calculate
Enter your total trading capital, the percentage of it you're willing to risk on this trade, your planned entry price, and your stop-loss price. The calculator finds the rupee amount you're risking (capital × risk%), then divides that by the per-share risk (the gap between entry and stop-loss) to tell you exactly how many shares to buy.
Formula
Shares = (Capital × Risk%) ÷ Risk per share
