DETAILS
This section explains what the calculator does, what goes into the result, and how to interpret the output so you can apply it confidently.
This calculator turns a few key inputs into a clear output you can act on — a number that traders and investors commonly use for planning and decision-making.
Use it to compare scenarios quickly and to understand the trade-offs behind the final result.
Treat the output as a planning number. Small changes in inputs (time, rate, price, quantity, risk, or cashflows) can change the outcome meaningfully — so keep assumptions realistic.
If the tool returns multiple outputs, focus on the ones that drive decisions (e.g., net result, breakeven, or risk-adjusted value), not just the biggest number.

HOW IT WORKS
Input your total available intraday trading capital — this is the total amount you are willing to deploy for intraday trades.
Choose what percentage of your capital you are willing to risk on this one trade. Professional traders typically risk 0.5% to 2% per trade.
Enter your planned entry price and stop-loss price. The calculator will tell you exactly how many shares to buy so your loss stays within your risk limit.
FAQ
Most professional intraday traders risk 0.5% to 2% of capital per trade. Beginners should start at 0.5% or 1%. Risking more than 2% per trade leads to large drawdowns that are mathematically hard to recover from.
Position sizing ensures that even if your stop-loss is hit (which will happen regularly), you only lose a fixed, manageable amount. This prevents a single bad trade from wiping out a large portion of your account.
A minimum of 1:1.5 (risk ₹1 to make ₹1.50) is generally acceptable for intraday. A 1:2 or higher R:R is ideal. With a 1:2 R:R, you can be profitable even with a 40% win rate.
The calculator gives the maximum shares to stay within your risk limit. You can buy less — never more. Also check that the position value does not exceed your available margin with your broker.
For options, use the premium as your entry price and your acceptable loss on the premium as the stop-loss. The same position sizing logic applies — your max loss on the trade should stay within your risk % limit.
