Hyperliquid Funding Rate Explained (2026): How Hourly Funding Hits Your PnL

The short version: On Hyperliquid, funding settles every hour (not every 8 hours like many CEXes). Positive funding means longs pay shorts; negative means shorts pay longs. The payment is position size × oracle price × funding rate, with a protocol cap of 4% per hour. Small hourly rates compound fast if you hold size overnight — so track fees + funding together if you want real net PnL.

You open a Hyperliquid perp, the chart looks fine, and a day later your wallet equity moved more than price alone can explain. That gap is often funding: a peer-to-peer transfer between longs and shorts that keeps the perpetual close to spot. On Hyperliquid it hits 24 times a day, so “I barely noticed funding” is a dangerous default.

This guide explains how the Hyperliquid funding rate works, walks through a numeric cost example, and shows why verifying net PnL (price move − fees − funding) matters more than the headline rate on the ticker.

What Hyperliquid funding is (and is not)

Funding is not a trading fee paid to the exchange. On Hyperliquid it is peer-to-peer: every dollar one side pays is received by the other side. No venue cut on the funding payment itself.

• Positive funding rate: longs pay shorts (perp trading rich vs spot / oracle).
• Negative funding rate: shorts pay longs (perp trading cheap vs spot / oracle).
• Settlement: every hour, applied to open perp positions at the interval.
• Notional base: payment uses the spot oracle price, not mark price.

That last point matters for PnL tracking. Mark price drives margining and liquidations; funding notional uses the oracle. If you rebuild “funding cost” from mark alone, you can be slightly off versus what actually settled.

Why Hyperliquid pays hourly (vs 8h CEX funding)

Many centralized venues publish an 8-hour funding cycle. Hyperliquid’s docs state that the formula is expressed as an 8-hour rate, but funding is paid every hour at one eighth of that computed rate. Practically, you get 24 settlements per day instead of three.

Implications for traders:

• Costs (or income) arrive in smaller chunks — easier to ignore until they add up overnight.
• A hot market can flip funding several times in a session; one “screenshot rate” is not your day.
• Comparing “0.01% funding” across venues without checking interval is apples-to-oranges.

Rule of thumb: when someone quotes a Hyperliquid rate, ask per hour or per 8 hours? The UI and docs are hourly-settlement oriented; third-party scanners sometimes annualize or rescale without labeling it clearly.

The funding formula (premium + clamped interest)

Hyperliquid’s published formula (for the 8-hour-style rate that is then paid hourly at 1/8) is:

F = Average Premium Index (P) + clamp(interest_rate − P, −0.0005, 0.0005)

In plain language:

1. Premium index (P) measures how far the perp book sits from the oracle. Hyperliquid samples premium about every 5 seconds and averages over the hour, so a one-second wick matters less than a sustained premium.
2. Interest component is fixed for consistency with CEX conventions: 0.01% per 8 hours, i.e. 0.00125% per hour (~11.6% APR bias toward paying shorts when premium is near zero). Docs describe this as reflecting USD vs crypto borrow cost differences.
3. Clamp (±0.05% on the interest−premium term) limits how much the interest piece can push F when premium is large — so a big premium still dominates.

Premium itself is built from impact bid/ask vs oracle (see Hyperliquid’s funding docs for the exact impact-notional definitions). HIP-3 builder markets can use a more responsive premium form; native HL perps follow the impact-difference style above.

How the payment hits your balance

At each hourly settlement:

funding_payment = position_size × oracle_price × funding_rate

• Long + positive F: you pay (balance decreases).
• Short + positive F: you receive.
• Signs flip when F is negative.

Payment is on notional, not on your margin. A $50,000 notional position at a tiny hourly rate still moves real dollars every hour — leverage only decides how painful that is relative to equity.

Cap: Hyperliquid caps funding at 4% per hour. That is a hard ceiling for extreme dislocations (more common on thin or newly listed books). Treat 4%/h as a risk boundary, not a typical rate — most liquid majors sit far below that in calm markets.

Worked example: funding cost over 24 hours

Assume a simplified hour where the settled hourly funding rate paid is +0.00125% (that is 0.0000125 in decimal — roughly the interest-only bias when premium ≈ interest). You are long 2 BTC, oracle price $100,000.

Notional: 2 × $100,000 = $200,000

One-hour payment (long pays): $200,000 × 0.0000125 = $2.50

Over 24 hours at the same rate: 24 × $2.50 = $60

Now stress it. Suppose a crowded long squeeze pushes settled hourly funding to +0.01% (0.0001) for 8 hours overnight, then returns to +0.00125% for the other 16 hours:

• 8h × ($200,000 × 0.0001) = 8 × $20 = $160
• 16h × $2.50 = $40
• Day total paid by the long ≈ $200 — before trading fees — even if BTC’s mid price barely moved.

That is the psychological trap: price PnL looks flat; funding quietly drained equity. Shorts in the same stretch received those dollars. Neither side “won the market”; one side won the funding transfer.

Quick reference table (same $200k long notional)

Hourly rate	Cost / hour	×24h (if constant)	Rough annualized*
+0.00125% (0.0000125)	$2.50	$60	~11%
+0.01% (0.0001)	$20	$480	~88%
+0.05% (0.0005)	$100	$2,400	~438%
+4% cap (0.04)	$8,000	n/a (unsustainable)	extreme only

*Rough annualized estimate: hourly_rate × 8760. This is a linear napkin math tool — not a forecast. Rates change every hour; you will not hold a fixed F for a year; and the 4% cap exists precisely because extremes are short-lived. Use annualization to compare magnitude, not to promise yield.

Funding vs fees vs price PnL

A clean mental model for Hyperliquid perps:

Net PnL ≈ price PnL − trading fees − funding paid + funding received ± other adjustments

Traders often obsess over entry fills and ignore the two silent drains: fees on turnover and funding on hold time. A high-turnover scalper feels fees first; a multi-day directional hold feels funding first. Both show up in wallet equity.

Useful habits:

• Before holding through several funding intervals, estimate notional × expected hourly rate × hours.
• If you are long into persistently positive funding, ask whether the thesis still beats the carry — or whether size should shrink.
• If you are farming negative funding with a short, remember liquidation and squeeze risk; carry is not free alpha.

How to “calculate” Hyperliquid funding in practice

People search for a Hyperliquid funding calculator for three different jobs:

1. Forward estimate: projected payment ≈ size × oracle × predicted hourly rate × hours held.
2. Backward audit: sum settled funding payments from account history / APIs over a period.
3. Cross-venue compare: rescale so 1h vs 8h quotes are comparable before you pick a book.

Third-party calculators and scanners (funding dashboards, alert bots) help with (1) and (3). They do not replace (2): only your settled payments tell you what actually left or entered the wallet. Predicted UI rates can differ slightly from the final averaged premium at the hour close.

If your goal is client acquisition or personal edge, prioritize systems that show net PnL after fees and funding on the wallet you actually trade — not just a market-wide funding heatmap.

FAQ: Hyperliquid funding rate

How often is funding paid on Hyperliquid?

Every hour. Docs describe an 8-hour-style formula paid at one eighth each hour — so you get 24 settlements per day, unlike many CEXes that settle only three times daily.

Do longs always pay shorts?

Only when the funding rate is positive. When funding is negative, shorts pay longs. The sign follows premium vs oracle over the averaging window, plus the clamped interest term.

Is funding calculated on mark price or oracle price?

The payment uses oracle price × size × rate. Mark price is central for margin and liquidations, but funding notional is oracle-based per Hyperliquid’s funding documentation.

What is the maximum funding rate?

Hyperliquid caps funding at 4% per hour. Caps and interval do not vary by asset on the documented design. Hitting the cap is rare on deep books and more plausible on thin or stressed markets.

Does Hyperliquid take a cut of funding?

No. Funding is peer-to-peer; the protocol does not collect a fee on funding payments.

How do I see funding’s impact on my PnL?

Sum settled funding from your account history, or use a read-only tracker that attributes wallet equity changes beyond raw price moves. Hyperfolio is built for that wallet-level view without requiring API keys or deposits.

Bottom line

The Hyperliquid funding rate is an hourly, oracle-notional, peer-to-peer transfer driven by average premium plus a clamped interest component, hard-capped at 4%/hour. Treat it as a first-class PnL line — especially if you hold size across many intervals. Estimate before you hold, audit after you trade, and judge strategies on net results after fees and funding.
