A position size calculator tells you exactly how many units to trade based on your account balance, the percentage you want to risk, your entry price and your stop-loss, so a losing trade only costs what you planned.
The core formula is simple: position size = (account balance × risk %) ÷ the distance from your entry to your stop-loss. Position Size Calculator runs it instantly and also factors in your take-profit targets to show risk-reward and projected P&L.
In three steps: enter your balance and risk percent, add your entry and stop-loss, then get your exact position size, potential loss and risk-reward instantly. Add up to five take-profit targets to see the reward at each level.
