Below is the liquidation price formula for USDT-M perpetual contracts under the cross-margin mode:
 
Long position: Liquidation price = (Account balance - Sum of maintenance margins for all other contracts, including closing fees + Sum of unrealized profits and losses for all contracts - 1 * position size * average position price) / (Position size * current contract maintenance margin rate - 1 * position size + position size* ticker fee rate)
 
Short position: Liquidation price = (Account balance - Sum of maintenance margins for all other contracts, including closing fees + Sum of unrealized profits and losses for all contracts - (-1 * position size * average position price)) / (Position size * current contract maintenance margin rate - (-1 * position size) + position size* ticker fee rate)
 
 
Below is the liquidation price formula for USDT-M perpetual contracts under the isolated-margin mode:
 
 
Long position: Liquidation price = (Position margin - 1 * Position size* Average position price) / (Position size * Maintenance margin rate - 1 * Position size + Position size * ticker fee rate)
Short position: Liquidation price = (Position margin - (-1 * Position size * Average position price)) / (Position size * Maintenance margin rate + 1 * Position size + Position size* ticker fee rate)
 
 
 

Maintenance Margin Rate (MMR)

You can find the “Maintenance Margin Rate” in the table below with the position value in USDT.
For example, if the position size of a USDT-margined BTCUSDT contract is 264,000 USDT, then the maintenance margin rate would be 1% (or 0.01).
 
Tier Position (USDT nominal value.) Max. Leverage Maintenance Margin Rate
1 0 - 50,000 125x 0.40%
2 50,000 - 250,000 100x 0.50%
3 250,000 - 1,000,000 50x 1.00%
4 1,000,000 - 3,000,000 20x 2.50%
5 3,000,000 - 6,000,000 10x 5.00%
6 6,000,000 - 8,000,000 5x 10.00%
7 8,000,000 - 10,000,000 4x 12.50%
8 10,000,000 - 12,000,000 3x 15.00%
9 12,000,000 - 20,000,000 2x 25.00%
10 20,000,000 - 40,000,000 1x 50.00%

 

FAQ:

Q: Can I adjust the leverage of my position?

A: If your position is in cross-margin mode, you can use the "Adjust Leverage" button to increase or decrease the leverage multiplier. If your position is in isolated margin mode, you cannot reduce the leverage ratio.

 

Important Note: If the nominal value of the position calculated using the liquidation price is different from the leverage level used in the calculation, you must try to substitute the maintenance margin rate for other leverage levels and recalculate the liquidation price.

 

Maintenance Margin

 

Maintenance Margin = Notional Position Value * Maintenance margin rate corresponding to the corresponding leverage level

 

For example:  If you hold 10 BTCUSDT perpetual contracts, and the latest mark price is 26,000. Then the nominal value of the position is 10 * 26,000 = 260,000, corresponding to tier 3 in the leverage and margin table.

 

All maintenance margin rates and amounts for USDT-M contracts can be found on the Leverage and Margin page.
