Position-sizing calculator
Decide in advance how much of your capital you are willing to lose on one trade, and this works out the maximum number of shares that keeps a stop-loss hit within that limit. It does not tell you what to trade. Platform gives no buy / sell advice.
How much of your capital you're willing to lose if the stop-loss is hit. Many traders use 1–2%.
Fill in the four fields to see the maximum position size.
Formula: risk budget = capital × risk% ; maximum shares = floor(risk budget ÷ |entry − stop|). It caps the quantity so that a stop-loss hit costs at most your chosen risk budget. It does not tell you what to trade, and is not advice.
This calculator does simple, disclosed arithmetic on the numbers you enter. It does not know the security, does not predict anything, and does not assess whether a trade is suitable for you. Platform is an information and research service — not a SEBI-registered investment adviser or research analyst, not a broker, and not affiliated with NSE, BSE or SEBI. It gives no buy / sell / hold recommendation. Verify every figure with official sources. Full disclaimer.
