Crypto Position Size Calculator
Enter your balance, risk %, entry and stop-loss to find the correct trade size so your loss never exceeds what you planned. The foundation of risk management on every trade.
How Position Sizing Works
The rule is simple: first decide how much you’re willing to lose (balance × risk %), then let your stop loss set the size. Size = amount risked ÷ (distance to stop as a %). This makes your loss at the stop exactly equal to your planned risk, regardless of price or leverage. Read more on setting a stop loss.
Frequently Asked Questions
Decide how much you’re willing to lose (balance × risk %), then divide it by the % distance to your stop loss. The result is the notional position size that makes your loss at the stop exactly equal to your chosen risk.

Yes. Risk-based position sizing is universal across all trading — Binance, Bybit, OKX and spot — because it depends on your balance and stop distance, not the platform.
