Risk a fixed amount, not a random one.
Professional traders decide how much to lose before they decide how much to buy. Set the percentage of capital you’re willing to risk, and this tool tells you the exact share count that keeps a stop-loss within that limit.
Educational tool only — it sizes risk, it doesn’t tell you what to trade. Charges aren’t included here; use the brokerage calculator for net P&L.
Why position sizing matters more than picking winners
You can be right less than half the time and still grow your account — if your losses are small and controlled. The trap most new traders fall into is risking a different, often huge, amount on every trade based on gut feel.
Fixed risk, every time
By risking the same small percentage on each trade, no single loss can seriously damage your account.
Survive losing streaks
Small, consistent risk means a run of losses dents your capital instead of wiping it out — so you’re still around to recover.
Removes emotion
The maths decides the size, not fear or greed. You enter every trade with a clear, pre-set amount on the line.
How it’s calculated
The calculation is simple and worth understanding so you can do it in your head:
Say you have ₹1,00,000 and risk 1% — that’s ₹1,000 you’re willing to lose on the trade. If you enter at ₹500 with a stop-loss at ₹480, your risk per share is ₹20. Dividing ₹1,000 by ₹20 gives 50 shares. If the stop is hit, you lose ₹1,000 — exactly your planned risk, no more.
Notice what happens when your stop is tighter: a ₹10 stop distance would let you buy 100 shares for the same ₹1,000 risk. A wider stop means a smaller position. The risk stays constant; only the size flexes.
