Free Forex Position Size Calculator

The correct position size formula with worked examples and code.

Formula

Position Size = (Account Balance x Risk%) / (Stop Loss x Pip Value)

Worked Examples

| Account | Risk | Stop | Pair | Pip Value | Position | | $1,000 | 1% | 20 pip | EURUSD | $10 | 0.05 lots | | $10,000 | 2% | 30 pip | XAUUSD | $1 | 0.67 lots | | $5,000 | 1.5% | 15 pip | GBPJPY | $9.3 | 0.54 lots |

Gold Warning

XAUUSD pip value is $1.00 per 0.01 lot, NOT $10.00 like EURUSD. Most calculators get this wrong.

Python

def position_size(balance, risk_pct, stop_pips, pip_value=10): return round(balance * risk_pct / 100 / (stop_pips * pip_value), 2)

JavaScript

function positionSize(balance, risk, stop, pipVal=10) { return parseFloat((balance * risk / 100 / (stop * pipVal)).toFixed(2)); }

Pip Values

EURUSD $10 | XAUUSD $1 | XAGUSD $5 | BTCUSD $1 | US30 $1
