Calculate your exact liquidation price on Binance USDT-M perpetual futures using Binance's maintenance margin rates.
Binance uses mark price (not last price) for liquidation calculations. Mark price is derived from the index price — a weighted average of spot prices across multiple exchanges — plus a funding basis. This prevents liquidations caused by temporary price spikes on Binance alone.
Key Binance-specific liquidation details:
Approximate formula for long positions: Liquidation price ≈ Entry × (1 − 1/Leverage + MaintenanceMargin%). Always use isolated margin to cap your maximum loss per position.
Liquidation Price
The price at which your leveraged position is forcibly closed by the exchange to prevent negative balance.
Mark Price
A fair-value price calculated from multiple spot exchanges that exchanges use for liquidation — preventing manipulated wicks from triggering false liquidations.
Maintenance Margin
The minimum account balance required to keep a leveraged position open — falling below this triggers liquidation.
Isolated Margin
A margin mode where only the funds specifically allocated to one position are at risk — losses are capped at your deposited margin for that trade.
Binance USDT-M perpetuals use a tiered maintenance margin system. For BTCUSDT, the base rate is 0.40% for positions up to 50 BTC notional. Larger positions have higher maintenance margin requirements. Always verify the current rate in Binance's risk parameters page.
Binance defaults to cross margin, where your entire futures wallet acts as collateral. In isolated margin mode, only the margin allocated to that specific position is at risk. Always verify your margin mode before opening a position.
