Buying ordinary shares? Enter three numbers to estimate how many shares fit within your planned price-loss limit. This is not a guaranteed maximum loss. Trading charges and an exit below your stop-loss can make the actual loss higher.
Check the purchase amount. Reduce the quantity if you cannot pay for it from your available trading money. A large calculated quantity is not permission to borrow or use leverage.
For ordinary shares bought first and sold later. Not for futures, options, fixed-lot products or selling first. No trading charges, tax, borrowing costs or unexpected price moves are included.
How the calculator works
Shares = planned loss limit ÷ (buying price − stop-loss price), rounded down to a whole share. Purchase amount = shares × buying price. Planned price loss = shares × the price difference. Amounts are calculated in paise to avoid rounding a share count upward by mistake.
Example: ₹500 ÷ (₹250 − ₹240) gives 50 shares. Buying them needs ₹12,500 before charges. This calculation assumes every share is sold at the entered stop-loss price. It does not check whether you have enough cash to buy them.
Why this is a planning tool
A stop-loss is not a promise that your loss will stop at the amount shown. Prices can jump past it; an order can remain unfilled. Brokerage and other charges are outside this estimate. Read How Much Should You Put Into One Trade? and Your Stop-Loss Price Is Not a Guaranteed Exit Price.
For education only, not a recommendation to trade or a guarantee of loss limits. The calculator itself does not save or submit your entries. Source: NSE trading system.
