Position size calculator
Risk a fixed % of your account per trade. Enter your balance, entry, and stop — we'll tell you exactly how many units to buy or sell.
Inputs
Most pros risk 0.5–2% per trade. Anything above 5% means you blow up after 20 stop-outs in a row.
Used only to compute required margin. 1× = spot/unleveraged.
Optional. Never let notional exceed this % of the account — size is clamped if it would.
Per side. Round-tripped (entry + exit) into net loss and breakeven.

P&L is net of round-trip fees + slippage.
Position size = (account × risk %) ÷ |entry − stop|. The dollar loss when stop hits equals exactly your risk budget — no surprises.
