What does this calculator show?
It combines the initial-margin ratio implied by leverage with the Maintenance Margin Rate entered by the user to estimate a Long or Short liquidation level.
The exchange calculation can also include position size, risk limit, maintenance-margin deduction, extra margin, funding, fees and margin mode. The output is educational, not an execution value.
Simplified formula
Long estimate = Entry × (1 − 1 / Leverage + MMR)Short estimate = Entry × (1 + 1 / Leverage − MMR)MMR = Maintenance Margin Rate ÷ 100This simplifies the relationship in the official Bybit formula by assuming zero maintenance-margin deduction and zero extra margin.
How to read the inputs
- Entry Price: use the current Average Entry Price after any position additions.
- Leverage: affects the initial margin required for a given position notional.
- Maintenance Margin Rate: varies by symbol and risk limit; enter the live value applicable to the position.
- Side: Long positions face liquidation risk as price falls, while Short positions face it as price rises.
Example: 100,000 entry, 10x Long, 0.5% MMR
- The initial-margin ratio is 1 ÷ 10 = 10%.
- The simplified calculation is 100,000 × (1 − 0.10 + 0.005).
- The estimate is about 90,500, or roughly 9.5% below entry.
- The live Bybit value can differ because of fees, deductions, extra margin, funding and account mode.
Why the live result can differ
- Cross Margin can change with available balance and unrealized P&L from other positions.
- Portfolio Margin uses portfolio-level risk and cannot be represented by this simple formula.
- Funding deducted from position margin can move liquidation closer to Mark Price.
- Risk-limit tiers can change the Maintenance Margin Rate and deduction.
- Liquidation can be triggered by Mark Price rather than Last Price.
Liquidation calculator FAQ
Can I use this result as an order value?
No. It is a simplified educational estimate. Confirm the live liquidation price, Mark Price, risk limit and margin mode in Bybit before trading.
Why does higher leverage move liquidation closer to entry?
For the same position notional, higher leverage reduces the initial margin ratio, leaving less room before maintenance-margin requirements are reached.
What happens when extra margin is added?
Extra isolated margin generally increases the loss buffer and moves liquidation farther from entry. This tool does not accept extra margin, so check the live position screen.
Why is Cross Margin not calculated?
Available balance and the P&L of other positions can change the result, so entry and leverage alone cannot produce a reliable Cross Margin liquidation price.
