Intro

Use this stop price calculator to turn a current price and stop percentage into a planned stop-loss price.

What this calculator does

The calculator starts with the current price, applies a selected downside percentage, and shows the calculated stop price. It includes common quick percentages plus a custom percentage field for your own rule.

How it works

Stop distance is current price x stop percentage. Stop price is current price - stop distance.

Example calculation

With a current price of 50 and a 20% stop, the stop distance is 10. The calculated stop price is 40.

How to use the result

Use the result as a quick planning level before placing or adjusting a stop order. Check the level against your trading plan, position size, spread, liquidity, and any broker order rules. This is an estimate and not financial advice.

Assumptions and limitations

  • The calculator assumes a long-position stop below the current price.
  • It does not include fees, spread, slippage, gaps, leverage, tax, or currency conversion.
  • It calculates a price level only; it does not place orders or guarantee execution.

FAQs

  • A 0% stop returns the current price.
  • Percentages must be below 100%, because a 100% stop would reduce the price to zero.
  • Use the position size calculator after choosing a stop level if you want to estimate trade size from account risk.
