Crypto Position Size Calculator
Good risk management means never losing more than a small, fixed slice of your account on any one trade. Enter your account size, the risk you'll accept and your entry and stop-loss prices to get the right position size.
Spot (unleveraged) sizing. Leverage, funding rates and slippage aren't modelled and all increase risk. Never risk money you can't afford to lose.
Why position sizing matters
The single most common way traders blow up an account is risking too much on one trade. Position sizing flips the process: you decide the maximum you're willing to lose (say 1–2% of your account), and the calculator works backwards from your stop-loss to tell you how large a position that allows. If the trade hits your stop, you only lose that pre-set amount.
How it works
Your amount at risk is your account × risk %. Divide that by the distance between your entry and stop-loss (the loss per unit) to get the number of units to buy, and multiply by the entry price for the position's dollar value. Keep the risk small and consistent, and no single trade can do serious damage. Pair this with self-custody discipline from our security checklist.
