# 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
