Liquidation price, profit and loss, fees and funding for any Hyperliquid perpetual. It uses Hyperliquid's own formulas, with live prices, maximum leverage and funding rates for all 179 perps.
How big a position can be when the stop should cost a set share of your account. It uses the market and fees above; stops fill as market orders.
Hyperliquid publishes the formula it uses (see also the maximum leverage and margin tiers of every perp):
liq_price = price − side × margin_available ÷ position_size ÷ (1 − l × side)
side is 1 for a long and −1 for a short. l is one over the maintenance leverage, and the maintenance margin is half the initial margin at the market's maximum leverage, so on a market that allows 40x, l is 1/80 and the maintenance margin is 1.25% of the position's value. margin_available is the position's isolated margin, or the whole account value in cross margin, minus that maintenance margin.
An example: a $1,000 long at 10x on a 40x market, entered at $100. The margin is $100 and the maintenance margin $12.50, so the position is liquidated at $91.14, a drop of 8.9%. The same trade at 20x is liquidated at $96.20.
Liquidation starts when account equity falls below the maintenance margin. If equity falls below two-thirds of it before the book can absorb the position, Hyperliquid's liquidator vault takes it over, and the maintenance margin is not returned.
Hyperliquid charges fees on the position's value at every fill: 0.045% to take liquidity and 0.015% to make it at the base tier, falling to 0.024% and 0% above $7B of 14-day volume. Staking HYPE takes 5% to 40% off, a referral code 4% off your first $25M, and the biggest makers earn a rebate of up to 0.003%. A front end can add a builder fee of up to 0.1% on perps. The full schedule is in the Hyperliquid fees guide.
Funding is paid every hour on position size × oracle price × the hourly rate. Longs pay shorts when the rate is positive; shorts pay longs when it is negative. The calculator fills in each market's current rate, and rates move every hour, so a longer hold is an estimate. Every market's rate, live, is on the Hyperliquid funding rates page. How far rates moved over a month, market by market, is in the September 2026 Hyperliquid funding report. For how much open interest each market carries, see Hyperliquid open interest by coin.
Margin tiers: on some markets very large positions carry a higher maintenance margin, which moves liquidation closer. Several positions in one cross account, which share the same account value. And slippage, plus the gap between the mark price that triggers liquidation and the oracle price that sets funding.
Use Hyperliquid's own formula: liquidation price = price − side × margin available ÷ position size ÷ (1 − l × side), where side is 1 for a long and −1 for a short, l is one over twice the market's maximum leverage, and margin available is your margin minus the maintenance margin. The calculator above does it for any market, in isolated or cross margin.
Half of the initial margin at the market's maximum leverage. On a market that allows 40x it is 1.25% of the position's value; on a 10x market it is 5%.
In isolated margin, yes: more leverage puts less margin behind the same position, so a smaller move liquidates it. In cross margin the whole account value backs the position, so what matters is the position's size against your account.
At the base tier, 0.045% of the position's value to take liquidity and 0.015% to make it, charged when you open and again when you close. A $10,000 position opened and closed with market orders pays about $9 in Hyperliquid fees.
Every hour you pay or receive position size × oracle price × the hourly funding rate. At the baseline rate of 0.00125% an hour, a $10,000 long pays $0.125 an hour, about $3 a day. Longs pay when the rate is positive and receive when it is negative.
It uses Hyperliquid's published formulas with live market data, so it matches the exchange for a single position of normal size. Very large positions on markets with margin tiers, cross accounts holding several positions, and funding rates that change hour to hour will all differ.
