Stop-loss Calculator

Every trade needs an exit plan before you enter. This stop-loss calculator works out where to place your stop using the three methods traders rely on — a percentage of the entry price, a multiple of the ATR, or the maximum rupee amount you're prepared to lose — for both buy and sell trades. It also shows the total risk on your quantity and the targets that give a 1:2 and 1:3 reward-to-risk.

How to use it

Choose buy or sell and the stop-loss method.
Enter your entry price, the method's value and your quantity.
Place the stop-loss order and note the targets.

Example

You buy 100 shares at ₹850 and the 14-day ATR is ₹18. A 1.5 × ATR stop is ₹27 away, at ₹823, risking ₹2,700 in total. A 1:2 target would be ₹850 + 2 × ₹27 = ₹904. If ₹2,700 is more than you want to risk, reduce the quantity rather than tightening the stop — theposition size calculator does this for you. Check the full trade with the risk-reward calculator.

Frequently asked questions

How do I calculate a stop-loss?

Three common ways: a fixed percentage below your entry (e.g. 2%), a multiple of the ATR (average true range) so the stop respects the stock’s normal volatility, or a fixed rupee amount you are willing to lose divided by your quantity.

What is ATR and why use it?

ATR (Average True Range, usually 14 periods) measures how much a stock typically moves in a day. A stop 1.5–2 × ATR away is less likely to be hit by ordinary noise than a tight fixed-percentage stop on a volatile stock. Most charting platforms show ATR as an indicator.

What is a trailing stop-loss?

A stop that moves up as price rises (for a long trade) but never moves down. For example, trailing by 1 × ATR or below each new higher swing low locks in profit while letting winners run.

Should I place a stop-loss order with my broker?

Many traders place a stop-loss (SL or SL-M) order immediately after entering, so the exit happens even if they’re away. Note that in a gap opening the fill can be worse than the stop price.
