An isolated-margin estimate for linear contracts; excludes closing fees, accrued funding, auto-added margin and other positions.
Calculation method and limits
Funding paid or received while holding is excluded from this tool: see how notional, leverage and funding payments relate.
How should I enter a position?
Choose an asset and a contract with usable tiers, then enter the actual entry price, base-asset quantity, leverage and added margin. Price uses the contract’s quote currency; margin uses its settlement currency. For 0.1 BTC enter 0.1, not a count of contracts or a dollar investment. The prefilled mark price is a starting example; replace it with the actual average entry for an existing position.
What determines the liquidation estimate?
Initial margin is entry notional divided by leverage, plus added margin. The liquidation boundary is where position equity, including directional unrealised P&L, equals the maintenance requirement. That requirement uses notional value and the applicable tier at the liquidation price, subtracting a maintenance deduction where the venue uses one. Changing size or leverage may change the tier, so a single fixed maintenance rate is insufficient.
Why might the venue display a different price?
The tool models an isolated linear contract, valuing quote and collateral units 1:1 without exchange-rate changes or collateral haircuts. It excludes cross or portfolio margin, inverse coin-margined contracts, fees, funding already paid or received, automatic margin additions and other positions. Parameters may change after collection. Liquidation typically uses mark price; execution prices also depend on liquidity. Verify the result against the venue’s account display and current risk rules.
