Funding Rate Explained: How Perp Funding Works & Is Paid

A funding rate is the small periodic payment that keeps a perpetual futures price tethered to the spot price of the underlying asset. Perps never expire and never settle, so there's no delivery date to force the contract price back toward spot — funding is the mechanism that does that job instead, by paying one side of the market to hold the position the other side is crowding out of. It's the defining feature of a perpetual, and the single cost most new perp traders overlook until it quietly eats into a position held for days.

This post explains what funding actually is, who pays whom when the rate is positive versus negative, the two components it's built from (a premium and a fixed interest rate), how often it's charged — Hyperliquid pays hourly while most centralized exchanges pay every 8 hours — and a clear worked calculation you can run yourself with nothing but the position size and the rate. We close with funding-rate arbitrage (carry) and where our own platform, Signalview, sits relative to all of this.

What funding is: the mechanism that pegs a perp to spot

A perpetual future is a contract that tracks an asset's price without ever expiring. Because it never settles, its traded price can drift away from the real spot price whenever one side of the market is more eager than the other. When lots of traders pile into longs, the perp trades above spot; when shorts dominate, it trades below. Funding corrects this by making the crowded side pay the other side a fee at regular intervals — a direct financial incentive that pulls the perp price back toward spot. If longs are paying, some of them close or shorts step in to collect the fee, and the gap narrows.

Crucially, funding is a peer-to-peer transfer between traders, not a fee the exchange keeps. The venue calculates the rate and moves the money between long and short accounts, but it doesn't take a cut of the funding payment itself. That's a different thing from trading fees, which the venue does collect — for how those work on Hyperliquid, see Hyperliquid Fees Explained. If you're still new to the instrument as a whole, What Is Perps Trading? covers perps, mark price and liquidation from the ground up; this post zooms in on funding alone.

Positive vs negative funding: who pays whom

When the funding rate is positive, longs pay shorts. A positive rate means the perp is trading at a premium to spot — the market is net-long and bullish — so longs, the crowded side, compensate shorts for taking the other side. When the funding rate is negative, shorts pay longs: the perp is trading below spot, the market is net-short or fearful, and shorts pay to be there. The sign tells you which way sentiment is leaning and which side is currently subsidizing the other.

Negative funding is worth dwelling on because it surprises people. If you're long an asset in a bearish market where the perp trades under spot, you can actually get paid to hold your position — shorts hand you funding every interval on top of any price move. It's not free money (you still carry full directional risk on the position), but it does mean the crowded, fearful side is paying you to lean against them. Persistent negative funding on a large asset is often read as a contrarian signal that shorts are overextended.

The two components: premium and interest

A funding rate is built from two pieces. The first is the premium (or premium index): a measure of how far the perp's price sits above or below the underlying spot/oracle price, sampled continuously through the interval. This is the part that actually reflects supply and demand — a big premium means longs are crowded and will pay a lot; a big discount means shorts are. The second is a fixed interest-rate component that represents the baseline cost of the borrowed capital implicit in a leveraged position. On Hyperliquid that interest rate is 0.01% every 8 hours (0.00125% per hour), which the docs describe as roughly 11.6% APR paid to shorts as a baseline.

Hyperliquid's exact formula is: Funding Rate = Average Premium Index + clamp(interest rate − Premium Index, −0.0005, +0.0005). In plain terms, the premium does most of the work, and the interest component nudges the rate by at most 0.05% in either direction. The premium is sampled every 5 seconds and averaged over the hour, and it uses impact bid/ask prices (the estimated fill price for a defined notional) against the oracle price rather than a single mid-price — a deliberate design choice that makes the rate harder to manipulate with a thin order book.

How often funding is paid: hourly vs every 8 hours

This is the detail that trips people moving between venues. Hyperliquid pays funding every hour. Most centralized exchanges — Binance, Bybit, OKX and similar — pay every 8 hours, on three fixed snapshots a day. Both models can describe the same economic cost; they just slice it differently. Hyperliquid computes the rate over an 8-hour window using the same style of formula a CEX uses, then settles one-eighth of it every hour, producing a continuous drip rather than three daily lump sums.

Two practical consequences follow. First, a 0.01% Hyperliquid hourly rate is roughly the same economic cost as a 0.08% Binance 8-hour rate — always normalize to the same time base before comparing venues, or you'll misjudge which is expensive. Second, hourly settlement is friendlier to short-term traders: a position opened and closed within the same hour on Hyperliquid pays no funding at all, whereas on an 8-hour venue whether you pay can depend on whether you happened to be open at the snapshot time. Hyperliquid also caps funding at 4% per hour — a deliberately generous ceiling that only binds in extreme dislocations, but it exists so a single crazy hour can't liquidate a position purely through funding.

A worked calculation you can do yourself

The formula is simpler than the mechanism. Your funding payment for an interval is: funding payment = position notional × funding rate. Position notional is your position size valued at the oracle price (Hyperliquid uses the oracle/spot price for this, not the mark price), and the funding rate is the rate for that interval. That's it — no leverage term appears directly, because leverage only affects how big a notional your margin controls, not the rate applied to it.

A concrete example. Suppose you hold a $10,000 long position and the funding rate is +0.01% for the hour. Your payment is $10,000 × 0.0001 = $1, and because the rate is positive, you (a long) pay that $1 to the shorts. Hold that position for 24 hours at the same rate and you'd pay roughly $1 × 24 = $24 that day — about 0.24% of the notional, which is why funding, not trading fees, dominates the cost of a multi-day perp position. Flip the sign: if funding were −0.01%, you'd receive $1 that hour instead of paying it. And note leverage's real role — if that $10,000 position was opened with 10x leverage on $1,000 of margin, the $1 hourly payment is 0.1% of your margin every hour, so funding compounds against a leveraged account far faster than the raw rate suggests.

To calculate funding yourself for any position: (1) take your position notional = position size × current oracle price; (2) find the current funding rate for that market and interval (shown on the venue's order ticket, usually as an hourly rate and often an annualized figure alongside it); (3) multiply notional × rate for the payment per interval; (4) check the sign — positive means you pay if long / receive if short, negative is the reverse; (5) multiply by the number of intervals you expect to hold to estimate total funding cost. Or use the calculator below — enter your position size, the funding rate and the interval, and it returns the payment per interval, per day and the annualized figure.

Funding-rate arbitrage and carry, honestly

Because funding is a real cash flow, traders build strategies around collecting it. The classic is the cash-and-carry (delta-neutral funding) trade: hold spot of an asset and short the perp against it in equal size, so you have no net price exposure but collect funding whenever the rate is positive. In a persistently bullish market with high positive funding, this can earn a steady yield on capital that's hedged against the asset's price. The reverse works when funding is deeply negative — hold the long perp and short spot (or borrow) to collect from the shorts.

The honest caveats matter more than the pitch. The yield is not risk-free: you pay trading fees to open and close both legs, funding can flip sign and start costing you, the two legs can be liquidated independently if you're not carefully margined, and hourly settlement means the rate you saw when you entered may not persist. Carry trades also tie up real capital for often-thin annualized returns once fees and the cost of the hedge are subtracted. Leverage amplifies all of it — before layering leverage onto any of this, read Leverage Trading Explained and know your Liquidation Price Calculator inputs cold, because a funding trade that gets liquidated on one leg stops being delta-neutral instantly.

Where Signalview fits

Funding is an input our strategies have to respect, not a headline feature we sell. Signalview (our product) is a non-custodial platform where authors publish backtested Hyperliquid perps strategies compressed into a single score from −100 to +100, which 24/7 AI agents trade on scoped keys that can place orders but never withdraw. Any strategy that holds directional perp exposure across intervals pays or receives funding automatically — it lands in the position's PnL like it does for any trader — so a strategy that looks profitable on price alone can be dragged down by persistently adverse funding, and a good backtest has to account for that. We don't add or take any funding ourselves; funding is a transfer between traders on Hyperliquid, and you pay only Hyperliquid's normal fees. For the full setup, see How to Use Hyperliquid.

Risk note: understanding funding does not make a leveraged position safe — you can still lose your entire margin to an adverse price move, and funding is an additional cost on top of that, not a substitute for managing it. Nothing here is investment advice.

Frequently asked questions

What is a funding rate in simple terms?

It's a small periodic payment exchanged between long and short traders that keeps a perpetual futures price close to the underlying spot price. When the perp trades above spot, longs pay shorts; when it trades below, shorts pay longs.

How often is the funding rate paid?

It depends on the venue. Hyperliquid pays funding every hour (settling one-eighth of an 8-hour-style rate each hour), while most centralized exchanges like Binance and Bybit pay every 8 hours on three fixed snapshots per day.

What does a negative funding rate mean?

A negative funding rate means the perp is trading below spot and shorts pay longs. If you hold a long position while funding is negative, you receive the payment each interval — though you still carry full price risk on the position.

How do I calculate my funding payment?

Use funding payment = position notional × funding rate, where notional is your position size valued at the oracle price. For a $10,000 long at +0.01% hourly, you pay $10,000 × 0.0001 = $1 that hour; a negative rate means you'd receive it instead.
