Crypto Position Size Calculator — Risk-Based Sizing
Size a position from your risk and stop-loss.
Formula & notes
Risk-based position sizing
Decide how much you are willing to lose on the trade (often 1–2% of the account), then size from the stop distance: position size = amount at risk ÷ |entry − stop|. Your loss at the stop stays fixed whether the stop is tight or wide.
If the position value exceeds your balance you need leverage; the minimum leverage is the ratio of the two. Using less leverage keeps the liquidation price further from your stop. Fees and slippage are not included.
Position size calculator: common questions
How do I calculate futures position size?
Position size = amount at risk ÷ |entry − stop|. With a 1,000 USDT account risking 1% (10 USDT), a long at 60,000 with a stop at 58,800 has a 1,200 stop distance, so the size is about 0.00833 BTC — roughly 500 USDT of position value.
How much should I risk per trade?
A common rule is 1–2% of the account, so even a long losing streak doesn't cripple it. Beginners should start at 1% or less.
Does leverage change the risk of the trade?
Once size and stop are fixed, the loss at the stop is fixed; leverage only changes how much margin you post. Higher leverage moves the liquidation price closer, which can liquidate you before the stop — so use the lowest leverage that fits the position.
Are fees included?
No. Opening and closing fees and slippage make the real loss slightly larger than the amount at risk, so leave a little margin by lowering the risk percentage.
