Stop-Loss & Take-Profit Calculator
Set your exits before you enter. Give the calculator your entry price, how far below it your stop sits (in percent), and the reward-to-risk you want — and it returns the exact stop-loss and take-profit prices.
Your plan
Set where you're wrong (the stop) as a % below entry, and how much reward you want for that risk. The calculator places the matching take-profit so the trade hits your reward-to-risk.
Stop & take-profit
Decide the stop first, then let the reward-to-risk set the target — not the other way around. A 4% stop at a 2:1 target needs only an 8% move to pay 2× what you risked.
How it works
Good exits are decided before the trade, not in the heat of it. Start with the stop — the price that proves the idea wrong — as a percentage below your entry. That distance is your risk per share. The take-profit then follows from the reward-to-risk you're willing to accept: at 2:1, the target sits twice as far above entry as the stop sits below it.
Letting the stop and reward-to-risk drive the target (rather than picking a hopeful price) keeps every trade consistent. A 4% stop with a 2:1 target only needs an 8% move to pay double what you risked — and if a name can't realistically travel that far to a logical level, that's a sign to pass.
StockSetups already draws the structural support and resistance on every chart and ships a stop and target with each setup, so you can sanity-check the levels this calculator produces against where price actually reacts.
Frequently asked
How do I calculate a stop-loss price?
Multiply your entry by (1 − stop % ÷ 100). A $50 entry with a 4% stop gives a stop-loss at $48. The distance from entry to stop ($2 here) is your risk per share.
How is the take-profit price set?
Take-profit = entry + (risk per share × reward-to-risk). With a $2 risk per share and a 2:1 target, the take-profit sits $4 above entry. This guarantees the trade hits your intended reward-to-risk if the target is reached.
Should I set the stop or the target first?
The stop. It's defined by where your idea is invalidated — a level on the chart. The target then follows from your reward-to-risk. Setting the target first and back-filling the stop is how traders end up with stops that are too tight or too wide.
