Isolated margin, USD-margined perp, funding ignored. Same formula as Hyperliquid's docs: liquidation when equity falls to the maintenance margin. Liquidation triggers on the mark price, not the last trade, and funding payments move your real liquidation price over time.

quick answer

How is liquidation price calculated?

For an isolated long: entry × (1 − 1/leverage) ÷ (1 − maintenance rate). For a short: entry × (1 + 1/leverage) ÷ (1 + maintenance rate). Fees and funding move it slightly over time.

how to use the perps liquidation price calculator

Find the price at which a leveraged perp position is liquidated, before you open it. Presets follow FOMO perps, which run on Hyperliquid with isolated margin (max 40x BTC, 25x ETH, 20x SOL, 10x most alts), or enter any exchange's maintenance margin.

guide

how FOMO perps liquidate

FOMO added perpetual futures in June 2026, routed to Hyperliquid and Trade[XYZ]. Every FOMO perp position uses isolated margin, with leverage caps of 40x on BTC, 25x on ETH, 20x on SOL and 10x on most other assets, and a 15 USDC minimum position. FOMO charges 0.05% of the position at open and close on top of Hyperliquid's fees, and funding is paid hourly. Perps are not available to US persons.

Hyperliquid sets the maintenance margin at half of the initial margin at the market's maximum leverage, and liquidates when your equity falls to it, based on the mark price. The calculator uses that exact rule.

worked example

Long SOL at $115 with 10x leverage on FOMO: SOL's max leverage is 20x, so maintenance margin is 2.5%. Liquidation = 115 × (1 − 0.1) ÷ (1 − 0.025) = $106.15, 7.7% below entry. Without the maintenance margin you might expect $103.50 (10% below); the real buffer is smaller.

frequently asked questions

What leverage does FOMO offer on perps?

Up to 40x on BTC, 25x on ETH, 20x on SOL and 10x on most other assets, in whole numbers, with isolated margin only.

What are FOMO's perps fees?

0.05% of the full leveraged position when you open and when you close, plus Hyperliquid's trading fee (0.045% taker at its base tier) and hourly funding.

Why was I liquidated above my calculated price?

Liquidation uses the mark price, not the last trade, and funding payments and fees reduce your margin over time. Keep a buffer between your stop and the liquidation price.
