Crypto Position Size Calculator
Find the position size that keeps your loss within your risk limit if the stop-loss is hit. Set your account size, the percent you are willing to risk, your entry, and your stop.
Position sizing controls how much you lose when a stop is hit; it does not control whether the trade wins. This tool assumes a spot position and does not model leverage liquidation or fees.
How Position Sizing Works
The idea is to fix your dollar loss before you enter. You choose how much of the account to risk, for example 1 percent of $10,000 is $100. The distance from your entry to your stop is the loss per unit. Dividing your dollar risk by that per-unit loss tells you how many units to buy so a stopped-out trade costs exactly your chosen amount.
Why it matters
Consistent sizing is what keeps a losing streak from ending your account. Two traders with the same strategy and very different sizing can have completely different outcomes. Sizing is the part of trading you fully control.
