Questions
How is the liquidation price calculated?
For an isolated USDT perpetual, the position is liquidated where its margin plus the unrealised loss falls to the maintenance margin. The maintenance margin is the position value times the maintenance-margin rate of the tier the position falls in, minus the tier's maintenance amount where the exchange publishes one. Long: (size × entry − margin − amount) ÷ (size × (1 − rate)). Short: (size × entry + margin + amount) ÷ (size × (1 + rate)).
Why does the same trade liquidate at a different price on each exchange?
Each exchange sets its own tiers: the position sizes, the maintenance-margin rate of each tier and the maximum leverage. A small position usually sits in the first tier everywhere, but the rates differ, and a large position climbs into higher tiers sooner on some exchanges than on others.
Where do the tiers come from?
From each exchange's own published risk-limit or position-tier tables, read automatically. Where an exchange publishes no table we can read, its tiers are kept by hand from the exchange's own page, with the date they were checked. Where neither exists, no liquidation price is shown for that exchange.
Is the result exactly what the exchange will do?
It is an estimate. Exchanges liquidate on the mark price, not the last trade, they may set aside an estimated closing fee, and funding payments change your margin over time. Treat the result as the level to stay well away from, not as a target.
What does cross margin change?
In cross margin the free balance of your futures account also backs the position, so the liquidation price moves further away. If you hold several positions, they share that balance, and a loss on one brings the others closer to liquidation. The cross-margin calculator shows each position's price if only that coin moves.
What is the funding rate?
A payment between longs and shorts every few hours that keeps the perpetual price near the spot price. When the rate is positive, longs pay shorts; when it is negative, shorts pay longs. The interval differs by exchange and sometimes by pair, which is why the funding page shows each exchange's own interval.
Which fee should I enter?
Your own taker fee on that exchange, in percent. Fees depend on your account level and any discount, so they are an input rather than a figure we set for you.
