What this liquidation estimate solves

Hyperliquid starts liquidation when account equity falls below maintenance margin. For an isolated position, the relevant equity is the margin assigned to that position plus its unrealized PnL. The calculator solves for the price where this equity equals the maintenance requirement for the tier you enter.

Position notional is converted into base-asset size at the entry price. A separate reserve can remove expected fees or funding from usable margin before the threshold is solved. This makes the assumption visible instead of silently treating every dollar of initial margin as available.

maintenance = size × liquidation_price × maintenance_rate − deduction
maintenance_rate = 0.5 ÷ maximum_leverage_for_tier
liquidation occurs when position equity = maintenance

Use the margin tier, not a universal maintenance rate

Hyperliquid’s standard assets have different maximum leverage, and several large markets use notional-based margin tiers. The official margin-table response supplies a maximum leverage for each tier. Maintenance margin is half the initial margin rate at that maximum leverage.

For example, a tier with 40× maximum leverage has a 1.25% maintenance rate. A 20× tier has a 2.5% rate. The trader may choose 10× leverage in either market, but the selected leverage does not replace the tier’s maintenance parameter. Larger positions can move into a different tier as price changes.

Tier maximum leverage	Maintenance rate
40×	1.25%
25×	2.00%
20×	2.50%
10×	5.00%
5×	10.00%
3×	16.67%

Why this tool refuses to fake cross margin

Cross positions share account equity. The liquidation price can move when another position gains or loses, when funding settles, or when collateral changes. Hyperliquid states that the actual cross-margin liquidation price is independent of the leverage selected for that position; lower selected leverage initially reserves more collateral but does not create an isolated account boundary.

Portfolio margin adds spot balances, borrowing, collateral LTV and a portfolio maintenance ratio. A form that asks only for entry price and leverage cannot reproduce either model. Use this calculator for isolated stress planning and the official interface for live cross or portfolio liquidation state.

The trigger is mark price, not the last chart print

Hyperliquid uses mark price for margin, liquidation, TP/SL triggers and unrealized PnL. The mark combines the oracle relationship, local book state and external venue inputs. During fast markets it can differ from the last trade or the price available for a large exit.

Recalculate after changing size or isolated margin. Keep a stop and liquidity buffer before the estimated threshold because reaching liquidation can send market orders to the book, where execution still depends on available depth. Positions above the documented threshold can enter partial liquidation.

Hyperliquid liquidation calculator FAQ

Is this Hyperliquid liquidation calculator exact?

It solves the isolated-position equity-equals-maintenance equation for one fixed margin tier. It can still differ from the official app if the position crosses a tier, funding or fees change margin, inputs are stale, or the live mark price and account state change.

Why does the calculator ask for maximum leverage?

Hyperliquid defines the maintenance margin rate as half the initial margin rate at the maximum leverage for the active margin tier. This is not necessarily the leverage selected for the position.

Can it calculate a cross-margin liquidation price?

No single-position form can reproduce cross margin honestly. Cross liquidation depends on account value, every cross position, their unrealized PnL and the maintenance requirement across the account. Use the official position display for cross margin.

What is the maintenance deduction input?

Tiered margin tables use a deduction so maintenance margin remains continuous when a position moves into a tier with a higher maintenance rate. Enter the current deduction from the applicable margin table; leave it at zero for a single-tier table.
