What is a Stop-Loss Calculator?

Use this stop-loss calculator to convert a percentage or dollar stop distance into a planned exit price. A stop-loss defines where a trade thesis is considered invalid, but an order may fill at a different price in fast markets.

Formula

Long stop = Entry × (1 − Stop percentage)

Example calculation

A 3% stop below a $100 long entry produces an estimated stop price of $97.

How to use this tool responsibly

  • Place stops using strategy logic, not emotion.
  • Account for volatility.
  • Stops do not guarantee an exact fill.
