Crypto funding rates explained: who pays, how much and how to read them

Crypto funding rates are periodic payments that traders holding long and short positions on perpetual futures pay each other, usually every 8 hours, to pull the contract price back toward the spot price. When funding is positive, longs pay shorts; when it is negative, shorts pay longs. Funding is charged on position value, so with high leverage even a small rate like 0.01% turns into a real cost if you hold a trade for several days.

This guide covers why perpetuals need funding, who pays whom, how to calculate the funding fee with a worked example, annualized funding, and how to read funding together with open interest and price. The live funding table on this page lets you check the numbers as you read.

Attribute	Value
Applies to	Perpetual futures only, not spot
Typical interval	Every 8 hours (3 times a day); some pairs use 4 hours or 1 hour
Positive funding	Longs pay shorts
Negative funding	Shorts pay longs
Charged on	Position value (size × price), not margin
Who pays or receives	Positions still open at the funding timestamp

Why do perpetual futures need a funding rate?

Perpetual futures need a funding rate because they never expire, so a recurring payment is what stops the contract price from drifting away from the spot price. A traditional futures contract has an expiry date, and on that date its price has to converge with the underlying asset. Perpetual futures remove the expiry, so funding takes over the anchoring job: payments are exchanged periodically between holders of the two sides of the contract to push the contract price toward the asset price, as described in Wikipedia: Perpetual futures (accessed 25 October 2026).

When too many traders go long with leverage, the BTC perpetual trades above spot, funding turns positive and longs have to pay. Holding a long gets more expensive, holding a short earns a payment, and the gap tends to narrow.

Positive vs negative funding rate: who pays whom?

A positive funding rate means longs pay shorts; a negative funding rate means shorts pay longs. The sign of funding shows which side is crowded and willing to pay up on the perpetual contract.

Funding rate	Contract price vs spot	Who pays	Who receives	Crowd leans
Positive (e.g. +0.01%)	Above spot	Longs	Shorts	Long
Negative (e.g. −0.01%)	Below spot	Shorts	Longs	Short

A negative funding rate usually appears when many traders open leveraged shorts. Negative funding does not mean price is about to rise; it only says that holding a short costs money and holding a long earns money right now. If you are not yet sure how the two directions work, read long vs short in crypto.

How to calculate the funding fee: a real cost example

The funding fee for each interval equals position value multiplied by that interval’s funding rate: funding fee = position size × mark price × funding rate. Margin and leverage are not part of the formula, so for the same position value, 5x and 20x pay exactly the same funding.

Example: with a 1,000 USDT account, you open a BTC long at 80,000 USDT with a position value of 909.50 USDT (about 0.0114 BTC). That is the size you get from risking 1% of the account with a stop about 1% from entry, worked through in stop loss in crypto. Funding is +0.01% every 8 hours:

• Per interval: 909.50 × 0.01% = 0.09 USDT (exactly 0.09095).
• Per day (3 intervals): 909.50 × 0.01% × 3 = 0.27 USDT.
• Over 30 days: about 8.19 USDT.

0.27 USDT looks tiny until you set it next to your margin. At 10x leverage the margin on this position is only about 90.95 USDT, so 0.27 USDT a day is roughly 0.3% of margin per day, or about 9% of margin after 30 days in the trade.

Funding cost for the same 909.50 USDT position at different rates (8-hour interval, assuming the rate stays constant):

Funding per 8h	Per interval	Per day	7 days	30 days
+0.01%	0.09 USDT	0.27 USDT	1.91 USDT	8.19 USDT
+0.03%	0.27 USDT	0.82 USDT	5.73 USDT	24.56 USDT
+0.05%	0.45 USDT	1.36 USDT	9.55 USDT	40.93 USDT
−0.01% (long receives)	+0.09 USDT	+0.27 USDT	+1.91 USDT	+8.19 USDT

The +0.05% row is the one I want you to remember. I trade by one rule: no trade may cost more than 1% of the account, so a 1,000 USDT account can lose at most 10 USDT on a single trade. Holding a long for 7 days at +0.05% funding costs 9.55 USDT, almost the whole risk budget of the trade, before price ever touches the stop. Funding is a cost to plan for, just like trading fees. You can total both with the trading fee calculator, and maker and taker fees from each exchange’s official fee page sit side by side in futures exchange fees compared.

What is an annualized funding rate?

An annualized funding rate converts one interval’s funding into a yearly rate: funding per interval × intervals per day × 365. For an 8-hour interval, annualized funding = funding × 3 × 365. The RonOnCrypto dashboard calculates its annualized column with exactly this formula.

• +0.01% every 8 hours → 10.95% a year.
• +0.05% every 8 hours → 54.75% a year.
• −0.02% every 8 hours → −21.9% a year.

Annualizing lets you compare funding with a familiar cost of capital, with two caveats. First, funding changes every interval, so the annualized figure is a snapshot of the moment you look, not your cost for the year. Second, a pair on a 4-hour interval must be multiplied by 6 instead of 3: the same 0.01% annualizes to 21.9%. Before comparing two funding numbers, check that they use the same interval.

How to read funding rates with open interest and price

A funding rate only tells you which way the crowd leans; to see whether leverage is building up or unwinding, read funding together with open interest (OI) and price direction. Open interest is the total value of open contracts: rising OI means new positions are opening, falling OI means positions are closing or being liquidated (see what is open interest). The four common cases below help you understand the market; they are not entry signals.

Price	Open interest	Funding	Common reading	Risk to watch
Up	Up	Positive, rising	New leveraged longs, the crowd is chasing price	A reversal can trigger cascading long liquidations
Up	Down	Mildly positive or falling	Shorts closing (buying back to exit), little new money	The rally may fade once short covering runs out
Down	Up	Negative, falling	New leveraged shorts, the crowd is chasing price lower	A bounce can trigger cascading short liquidations
Down	Down	Back near zero	Longs closing or being liquidated, leverage unwinding	Volatility is usually high during the flush, then may calm

One more case: price moves sideways, OI rises sharply and funding leans hard to one side. Leverage is piling up on the crowded side, and the market tends to move violently when that side gets squeezed. This case does not tell you which way price will break; it is a reminder that your liquidation price must sit well beyond your stop. Check that distance with the liquidation price calculator.

Common mistakes when reading funding rates

The most common mistake is treating the funding rate as a buy or sell signal, when it is only a holding cost and a gauge of crowd positioning. Four mistakes come up again and again:

1. Fading funding mechanically. High positive funding can last for days in a strong uptrend. Opening a short just because “funding is too high”, without a stop, is a bet on timing, not on data.
2. Calculating funding on margin. Funding is charged on position value. 90.95 USDT of margin at 10x still pays funding on a 909.50 USDT position.
3. Comparing different intervals. 0.01% every 4 hours costs twice as much as 0.01% every 8 hours. Always check the interval first.
4. Reading funding on its own. Without OI and price direction, positive funding only says “longs are crowded”, not whether that is new money coming in or shorts leaving.

In my first year of trading I lost more than I won, because I entered out of fear of missing out and held losers because I would not admit I was wrong. Funding did not cause those mistakes, but a losing trade held too long also gets chipped away by funding every 8 hours.
