Bybit Liquidation Price Calculator
Work out where an isolated-margin Bybit perpetual is liquidated, for a long or a short, with Bybit's own maintenance margin tier for the coin and the position value you enter, not one default rate. The form starts with the live price of the coin you pick.

Worked example
BTC long, the numbers above- You open a 10x long of 0.118848 BTC ($10,000.00) at $84,141.30. Your initial margin is $10,000.00 ÷ 10 = $1,000.00.
- Bybit puts a $10,000.00 position in risk tier 1: a maintenance margin rate of 0.33%, and at most 150x leverage.
- Bybit values the maintenance margin at the entry price: $10,000.00 × 0.33% = $33.00.
- Liquidation price = entry − (initial margin − maintenance margin) ÷ quantity = $84,141.30 − ($1,000.00 − $33.00) ÷ 0.118848 = $76,004.84.
- That is 9.67% below your entry.
How Bybit calculates liquidation
BTCUSDTBybit's formula for an isolated USDT perpetual: liquidation price = entry − (initial margin − maintenance margin) ÷ quantity for a long, entry + the same for a short. The initial margin is position value ÷ leverage and the maintenance margin is position value (at the entry price) × the maintenance margin rate of its risk limit tier, less the tier's mmDeduction, which keeps the margin continuous from one tier to the next. Leave the fee at 0 for Bybit's formula as published, or enter your taker fee to also reserve the fee to close (at the bankruptcy price). Liquidation is triggered by the mark price, not the last trade.

The formula
Long: Liquidation = Entry − (Initial margin − Maintenance margin) ÷ Quantity
Short: Liquidation = Entry + (Initial margin − Maintenance margin) ÷ Quantity
This is Bybit's published formula. Initial margin = position value ÷ leverage and maintenance margin = position value × MMR − mmDeduction, both at the entry price, with the MMR and the deduction of the risk limit tier your position value falls in. A fee above 0 adds the fee to close (bankruptcy price × quantity × fee) to the maintenance margin. Quantity = position value ÷ entry.
Bybit Liquidation Price Calculator FAQ
What maintenance margin rate does Bybit use?
It depends on the coin and on the position value: each risk limit tier has its own rate, rising with the size. This page reads the tiers from Bybit's public risk limit endpoint and picks the one for your position value.
What is Bybit's mmDeduction?
A fixed USDT amount subtracted from the maintenance margin in the higher tiers, so the margin doesn't jump when a position crosses into the next tier. The first tier has none.
How is the Bybit liquidation price calculated?
With Bybit's published formula. For an isolated long: entry − (initial margin − maintenance margin) ÷ quantity; for a short: entry + (initial margin − maintenance margin) ÷ quantity. Initial margin is quantity × entry ÷ leverage, and maintenance margin is quantity × entry × maintenance margin rate − mmDeduction, both valued at the entry price. The rate and the deduction come from the risk limit tier your position value falls in.
Where can I see every tier?
