The exact formula behind every calculator — position sizing, pip value, the Kelly criterion adjusted for forex leverage, and more.

Plain-English explanations of pips, leverage, margin calls, and the things every new trader gets wrong once.

Position size = (account balance × risk %) ÷ (stop in pips × pip value). Decide the cash you'll risk, divide it by your stop distance times the per-pip value for the pair, and you get the number of lots so a stop-out costs exactly your planned risk. The position size calculator does the currency conversion for you.

Pip value is what a one-pip move is worth on your position. For a standard lot (100,000 units) one pip is the pip size (0.0001, or 0.01 for JPY pairs) × 100,000 in the quote currency, then converted to your account currency at the current rate. See the pip value calculator.

Margin = notional value ÷ leverage. One standard lot of EUR/USD is 100,000 EUR; at 1:30 leverage the margin is about 3,333 EUR, converted to your account currency. EU retail is capped at 1:30 on majors, US retail at 1:50. Try the margin calculator.

Many traders target at least 1:2. At 1:2 you only need about a 33% win rate to break even; at 1:1 you need 50%; at 1:3 even a 25% win rate is profitable. The risk:reward calculator shows the breakeven win rate for any entry, stop and target.
