CRYPTO POSITION SIZE CALCULATOR

Position sizing is one of the most critical — and most overlooked — aspects of trading. The Position Size Calculator helps you determine the correct trade size based on your account balance, risk tolerance per trade, entry price, and stop-loss level. Trading without defined position sizing is one of the most common causes of account blowup, even when the underlying trade idea is correct.

The fundamental formula: your maximum loss in dollar terms (account size x risk percentage) divided by the distance between your entry and stop-loss gives you the position size. A trader with a $10,000 account risking 1% per trade ($100) with a $500 entry and a $490 stop-loss should trade 10 units. Consistent application of this formula ensures no single losing trade can cause catastrophic damage.

Risk-to-reward ratio (R:R) is the companion metric to position sizing. A trade with a 1:3 R:R means you risk $1 to make $3. Even with a 40% win rate, consistent 1:3 R:R trades are profitable over time. This calculator helps you define your reward target relative to your risk, allowing you to evaluate whether a setup has the mathematical expectancy to be worth taking.

Leverage amplifies both gains and losses — and changes the calculation significantly. A 10x leveraged position means your stop-loss needs to be proportionally tighter relative to notional value to keep your actual dollar risk within your defined limit. This calculator accounts for leverage, ensuring that your risk management holds even in leveraged crypto derivatives markets where liquidation risk is real.
