Stop loss calculator
The exact stop loss price for your trade, and what it costs in cash and as a share of your account.
Excludes spread, commission and slippage.
Conversions use reference rates from 6 October 2026. Your broker’s live prices will differ slightly.
Stop first, size second
The stop loss is the price that says your idea was wrong. Choose it from the chart, then adjust your position so the loss stays inside your plan. If the loss above is bigger than you want, change the lot size, not the stop. The lot size calculator works backwards from your risk, and the take profit calculator sets a target from the same stop.

FAQ
How do you calculate a stop loss price?
For a buy, stop price = entry − (stop pips × pip size). For a sell, stop price = entry + (stop pips × pip size). A buy on EUR/USD at 1.0850 with a 25-pip stop has its stop at 1.0825.
How far away should my stop loss be?
Place it where your trade idea is proven wrong, such as beyond a swing high or low, not at a fixed number of pips. Then size the position so that distance costs only your chosen risk.
Can price move past my stop loss?
Yes. In fast markets, around news or over a weekend gap, a stop can fill at a worse price. This is called slippage. A guaranteed stop, where your broker offers one, removes that risk for a fee.
