Most “liquidation price” formulas floating around trading communities are simplified approximations — they ignore maintenance margin tiers and the exact per-asset max leverage Hyperliquid actually enforces. Close enough for a rough mental estimate, not close enough to size a real position.
Why the common approximation is wrong
The formula most traders memorize — entry price adjusted by 1/leverage — assumes a fixed maintenance margin ratio and ignores that Hyperliquid sets max leverage per asset individually, not as a single platform-wide number. A position at 20x on an asset whose real max leverage is 10x will hit its actual liquidation threshold well before the simplified formula predicts.
What actually determines your liquidation price
Isolated margin liquidation on Hyperliquid depends on your entry price, position size, the margin you’ve allocated, and the maintenance margin requirement for that specific asset — which is itself a function of the asset’s max leverage tier. Get any one of these slightly wrong in a manual calculation and your estimated buffer is off.
Isolated vs. cross margin
Isolated margin isolates risk to the capital you’ve allocated to that specific position — if it liquidates, the rest of your account is untouched. Cross margin shares your entire account balance as collateral across all open positions, which can delay liquidation on any single position but also means a bad move on one asset can drag down your whole account. Most calculators — including simplified mental math — only really model the isolated case cleanly.
Summary
Don’t size leveraged positions off a rule-of-thumb formula. Max leverage varies per asset, maintenance margin follows from that, and getting the calculation wrong by even a small margin can mean the difference between a position that survives a normal pullback and one that doesn’t.
