Risk warning: Spread bets and CFDs are complex, leveraged products — most retail accounts lose money. Check any provider's published loss rate, and never risk money you can't afford to lose.

The number that matters isn't the deposit — it's the exposure. Enter a stake and level to see what a bet really commits you to before you place it.

Illustrative only. Excludes overnight funding, dividend adjustments and slippage. Losses are calculated on full exposure and can exceed your margin deposit without guaranteed-stop protection. FX tip: enter levels in points, not the raw rate — GBP/USD 1.3500 is 13,500 points if your stake is per point (0.0001).

Reading the results

Notional exposure is the market value your stake controls (level × stake) — the number your losses are calculated on. Margin required is the deposit your provider takes, using FCA minimums by asset class. If the position moves against you, losses come out of your account at full-exposure scale; at 50% of required margin, providers must close retail positions. Size stakes from your maximum acceptable loss — see the position-sizing guide.
