How do I calculate crypto position size?

Enter your account balance, the percentage of your account you're willing to risk (typically 1–2%), your entry price, and your stop-loss price. The calculator outputs the exact position size that limits your loss to your chosen risk percentage if the stop-loss is hit.

What is the 1% risk rule in trading?

The 1% risk rule means you risk no more than 1% of your total account balance on any single trade. If you have a $10,000 account and risk 1%, your maximum loss per trade is $100. This rule preserves capital during losing streaks and is one of the most widely recommended risk management practices for crypto traders.

Does the risk calculator work for futures trading?

Yes. The position size formula works for spot, margin, and futures trading. For futures, use your effective account margin as the account balance, set your entry price, and your stop-loss. The output is the notional position size — divide by your leverage to see the margin required.

What inputs do I need for the position size calculator?

You need three inputs: (1) Account balance in your base currency (e.g., USD or BTC value), (2) Risk percentage per trade (e.g., 1%), and (3) Entry price and stop-loss price for the trade. The calculator computes dollar risk, position size, and R:R ratio automatically.
