Position Size Calculator
Free position size calculator for traders. Enter account size, risk %, entry, and stop-loss to find exactly how many shares to buy on any trade.
Risk a Fixed Percentage on Every Trade
Most professional traders risk 0.5% to 2% per trade. Enter your account size, the percentage you are willing to risk, your entry price, and your stop-loss, and the calculator returns the exact share size that keeps your loss within that limit.
Position Sizing Is the Core of Risk Management
Consistent position sizing keeps a single bad trade from undoing weeks of work. Pair this with the risk/reward and trade expectancy calculators to size every setup around a defined edge.
