Your liquidation price is where your collateral, after the loss on the position, falls to the exchange's maintenance margin. A $10,000 long on BTC at 60,000 with 10× isolated leverage and a 0.5% maintenance margin rate liquidates at about 54,271, 9.55% below entry.
How is the liquidation price calculated?
For a USDT-margined perpetual, the exchange closes your position when your collateral plus unrealised P&L falls to the maintenance margin. Solving that for price gives:
Long: Liq = (Q × Entry − Collateral − Maint. amount) ÷ (Q × (1 − MMR))
Short: Liq = (Q × Entry + Collateral + Maint. amount) ÷ (Q × (1 + MMR))
Q = position size ÷ entry price
Collateral = position size ÷ leverage (isolated)
= wallet balance (cross, one open position)
MMR = maintenance margin rate
This is the form Binance publishes for USDⓈ-M futures, applied to a single position. Bybit publishes a close variant that values maintenance margin at the entry price instead of the liquidation price, so its figure can differ slightly. Your exchange's position screen is the final word.
Worked example
A $10,000 long on BTCUSDT at 60,000 with 10× isolated leverage and a 0.5% maintenance margin rate:
- Quantity: 10,000 ÷ 60,000 = 0.166667 BTC
- Collateral: 10,000 ÷ 10 = $1,000
- Liquidation: (10,000 − 1,000) ÷ (0.166667 × 0.995) ≈ 54,271.36, 9.55% below entry
- Bankruptcy price, where collateral is fully gone: 54,000
Liquidation comes before bankruptcy because the exchange keeps the maintenance margin to close you out.
Why your exchange may show a different number
- Mark price. Liquidation is triggered by the mark price, not the last traded price.
- Tiers. The maintenance rate rises with position size. Larger positions sit in higher tiers with a maintenance amount.
- Fees and funding. Both come out of your margin over time and pull the liquidation price closer.
- Cross margin. Other open positions share the same wallet, so their P&L moves this one's liquidation price.
How AI Trading Fleet limits the damage
Every Fleet order goes through propose(), a pure risk check. It caps size per position, per venue, per strategy and per market, stops trading for the day at your daily loss cap, and halts at your drawdown limit. The kill switch stops all new orders at once from the dashboard, a signed webhook or Telegram.
Questions
What is a liquidation price?
The price at which the exchange force-closes a leveraged position because the collateral left, after the loss, has fallen to the maintenance margin.
Does higher leverage bring the liquidation price closer?
Yes. With isolated margin the collateral is position size divided by leverage, so at 10× the liquidation price sits roughly 10% from entry, at 20× roughly 5%, minus the maintenance margin.
Is the liquidation price the same on Binance and Bybit?
Close but not always identical. Both close a position at the maintenance margin, but they value it slightly differently and use their own tier tables. Check the maintenance rate for your symbol and size on your exchange.
Why is my exchange showing a different liquidation price?
Usually because of the maintenance tier for your size, fees and funding already taken from margin, or other positions sharing a cross-margin wallet.
