What this result means
A practical interpretation before the formula details.
MODEL
Transparent estimate
The calculator uses entry price, leverage, maintenance margin and the margin you make available to the position.
EXCHANGE REALITY
Exact formulas vary
Exchanges can use mark price, tiered maintenance rates, fees, funding and account-level rules. Treat this as an estimate, not an exchange quote.
How it is calculated
The simplified linear-perpetual model used by this tool.
Long
Pliq = (E × (1 − 1/L) − Mextra/Q) ÷ (1 − MMR − F)Short
Pliq = (E × (1 + 1/L) + Mextra/Q) ÷ (1 + MMR + F)E = entry price, L = leverage, Mextra = additional available margin, Q = position units, MMR = maintenance margin rate.

Method, example and limitations
Reference example: entry $100, 10× leverage, 0.50% maintenance and 0.05% estimated closing fee gives approximately $90.50 for a Long and $109.40 for a Short before additional margin.
Scope: linear USD-margined contracts with one constant maintenance rate. The optional mark price measures the remaining buffer and warns when the modeled boundary is already crossed.
Cross margin is only a scenario because other positions, unrealized PnL, funding, tiers and exchange-specific deductions can change available equity. Reviewed August 21, 2026.
