What Is Funding Rate in Crypto Futures? Simple Guide
Funding rate is a fee longs and shorts pay each other on perpetual futures, often every 8 hours. See how 0.01% works out in USDT and rupees, with worked maths.
The funding rate is a periodic payment between traders who are long and traders who are short on a perpetual futures contract. When it is positive, longs pay shorts; when it is negative, shorts pay longs. The exchange does not keep it. Its job is to pull the perpetual contract's price back towards the spot price, because perpetuals never expire. On many exchanges it is settled every 8 hours, and a common baseline is 0.01% per 8 hours.
Key takeaways
- Funding only applies to perpetual futures, not to spot trades or dated futures.
- Payment = position value × funding rate, charged at each funding time you hold the position.
- At +0.01% per 8 hours, an 8,500 USDT long pays about 0.85 USDT each time, or about 2.55 USDT a day.
- Because it is charged on the full position, funding eats into your margin faster when you use leverage.
- Intervals and formulas differ by exchange and contract; always check the contract details screen.
Why funding exists
A normal futures contract has an expiry date, and on that date its price must meet the spot price. A perpetual contract has no expiry, so it needs another way to stay close to spot. Funding is that mechanism. If the perpetual trades above spot because many traders are leveraged long, the funding rate turns positive and longs pay shorts. That makes holding a long more expensive and a short more attractive, which pushes the contract back towards spot. The reverse happens when shorts dominate. If you are new to futures, start with spot vs futures trading.
How the funding rate is calculated
Exchanges use slightly different formulas, but most combine two parts:
- A premium component, based on how far the perpetual price has been above or below the spot index during the interval.
- An interest component, a small fixed figure reflecting the cost of borrowing one currency against another. On many exchanges this is set so that the funding rate sits near 0.01% per 8 hours when the perpetual and spot are in line.
Exchanges also cap how high or low the rate can go in one interval, and some shorten the interval for a contract during extreme moves. Because the details are exchange-specific, treat any number in this guide as an illustration and read the funding section of your platform's contract specifications.
Worked example: what you actually pay
Suppose bitcoin is at 85,000 USDT (it was about $84,900 on 27 September 2026; the live price is $83,030.68). You open a 10x long of 0.1 BTC:
- Position value: 0.1 × 85,000 = 8,500 USDT
- Margin you put up at 10x: 850 USDT
| Funding rate per 8 hours | Per interval | Per day (3 intervals) | Per 30 days | 30 days as % of 850 USDT margin |
|---|---|---|---|---|
| +0.01% | 0.85 USDT | 2.55 USDT | 76.5 USDT | 9% |
| +0.03% | 2.55 USDT | 7.65 USDT | 229.5 USDT | 27% |
| +0.05% | 4.25 USDT | 12.75 USDT | 382.5 USDT | 45% |
| -0.01% | You receive 0.85 USDT | You receive 2.55 USDT | You receive 76.5 USDT | +9% |
At USD/INR of about 95.82, 2.55 USDT a day is roughly ₹244, and 76.5 USDT over a month is roughly ₹7,330. The table assumes the rate stays the same, which it never does exactly, and the position value changes as the price moves, so real payments will differ. The point is clear though: a rate that looks tiny per interval becomes a large cost against your margin if you hold a leveraged position for weeks. A steady +0.01% per 8 hours works out to about 10.95% a year on the full position value.
Funding times in IST
Many exchanges settle funding every 8 hours. On Delta Exchange India, for example, funding is exchanged at 05:30, 13:30 and 21:30 IST, according to the exchange's own help pages, and it has said some contracts may use shorter intervals. Other platforms may settle hourly, every 4 hours or at different times, and can change their schedule. You only pay or receive funding if you hold the position at the settlement moment.

What the funding rate tells you about the market
Traders watch funding as a sentiment gauge:
- High positive funding means many leveraged traders are long and paying up for it. Crowded longs can unwind sharply if the price dips and liquidations cascade.
- Negative funding means shorts are crowded. A rise in price can force them to buy back, which can add fuel to a rally.
- Near-baseline funding suggests leverage is balanced.
Funding is a signal, not a prediction. It can stay high for weeks in a strong trend. Pair it with other indicators such as the fear and greed index.
How to manage funding costs
- Check the current and predicted funding rate on the contract page before opening a position.
- If you plan to hold for weeks, compare the expected funding cost with simply buying spot, which has no funding.
- Use lower leverage, so funding is a smaller share of your margin.
- Note the next funding time. Opening just after a settlement gives you nearly a full interval before the next payment.
- Keep enough free margin. Funding is deducted from margin and can move your liquidation price closer.

Crypto futures are available to Indians on FIU-registered platforms; check the FIU-registered exchanges list. How futures profits and funding payments are taxed is not settled in a single clear rule, and treatment can differ from spot VDA gains.

FAQ
Who pays the funding rate, longs or shorts?
When the rate is positive, longs pay shorts. When it is negative, shorts pay longs. The exchange passes the money between traders rather than keeping it.
How often is funding charged?
Every 8 hours is common, but some exchanges and contracts use 1-hour or 4-hour intervals. Check the contract specification on your platform.
Do I pay funding on spot crypto?
No. Funding applies only to perpetual futures positions held at a funding time.
Is 0.01% funding rate high?
No, 0.01% per 8 hours is a typical baseline on many exchanges. It still adds up to about 10.95% a year of your position value if held continuously.
