Position Size Calculator
Compare a position-size scenario from your inputs
How Position Sizing Works
This calculator compares a hypothetical position size from the account balance, risk-budget percentage, entry price, and planned exit threshold you enter.
Formula: Position Size = Risk Amount / (Entry Price - Stop Loss Price)
Risk Amount = Account Balance × Risk Percentage
Calculated from the values you entered. Your exchange may use different margin rules.

Understanding Optimism Liquidation
Liquidation rules for Optimism differ by exchange, product, account, margin mode, and maintenance tier. This page uses a simplified scenario and cannot reproduce every exchange calculation.
Inputs and exchange rules that can affect a result:
- Leverage input: changes the estimated distance to the modeled threshold.
- Position size: may affect the maintenance tier applied by an exchange.
- Maintenance margin: varies by exchange, product, account, and margin mode.
- Market conditions: fees, funding, slippage, and fast execution can change the outcome.
