Know exactly how much to risk before you click Buy. Calculate position size, R:R ratio and liquidation price in seconds.
Proper position sizing is the foundation of risk management in crypto trading. This calculator helps you determine exactly how many coins or USDT to buy based on your account size and the risk you're willing to take per trade.
Enter your account balance, set your risk percentage (most professional traders use 1–2%), input your entry price and stop-loss level, and the calculator instantly shows your optimal position size. If you have a take-profit target, you'll also see your Risk:Reward ratio.
Position sizing determines how much of an asset to buy. The formula: Risk Amount ÷ (Entry − Stop Loss) = Quantity. For example, if your risk is $100 and your SL is $500 away, you buy 0.2 BTC.
Most professional traders target at least 1:2 Risk:Reward — risking $1 to make $2. At 1:3 or higher you can be profitable even with a 40% win rate. Never take trades below 1:1.5.
The standard rule is 1–2% of your account per trade. At 1% risk, you'd need to lose 100 consecutive trades to blow your account. Professional algo traders often use 0.5% or less.
In futures trading, your position is liquidated when price moves against you by (100% ÷ Leverage). At 10× leverage, a 10% move wipes out your margin. Always calculate liquidation price before entering.
