Perpetual contracts have become one of the most popular derivatives in the digital asset trading space, offering traders leveraged exposure without an expiration date. A key mechanism that distinguishes perpetual contracts from traditional futures is the funding fee—a periodic payment exchanged between long and short positions to keep the contract price aligned with the underlying market. In this guide, we’ll explore how funding fees work, when they’re charged, and how to view them on trading platforms.
What Are Funding Fees in Perpetual Contracts?
Funding fees are regular payments made between buyers (longs) and sellers (shorts) in a perpetual contract market. Unlike traditional futures, perpetual contracts do not expire, so there’s no natural price convergence at settlement. To ensure the contract price stays close to the spot market value, exchanges use funding fees as a balancing mechanism.
When the price of a perpetual contract trades above the index price (indicating more longs), longs pay shorts a funding fee. Conversely, if the contract trades below the index price (more shorts), shorts pay longs. This incentivizes traders to bring the market back into equilibrium.
Funding fees are typically settled every 8 hours, and no actual trading occurs during this process—funds are simply transferred between accounts based on open positions at the time of settlement.
How Often Are Funding Fees Charged?
As mentioned, funding fees are generally charged every 8 hours across most major platforms. These intervals are usually fixed and occur at predictable times—commonly at 00:00 UTC, 08:00 UTC, and 16:00 UTC. Traders can check the exact schedule within their trading interface.
It’s important to note:
- You only pay or receive funding if you hold a position at the moment the fee is applied.
- If you close your position before the funding timestamp, you won’t be charged.
- Funding rates are usually small percentages but can spike during periods of high volatility or strong market bias.
Where to Find Funding Rate Information
On most trading platforms, including OKX, you can easily view the current funding rate for any perpetual contract. Look for it in the contract details section of the trading interface. It's typically displayed as a percentage and may also show the next estimated funding time.
Key data points to monitor:
- Current funding rate
- Next funding time
- Historical funding rates
This transparency allows traders to anticipate costs and adjust their strategies accordingly—especially important for carry trades or long-term holding strategies.

Understanding Index Price, Mark Price, and Last Traded Price
To fully grasp how funding fees are calculated and why they exist, it’s essential to understand three critical price metrics used in perpetual contracts:
1. Last Traded Price
This is the most recent price at which a trade was executed on the order book. It reflects real-time supply and demand but can be volatile and subject to manipulation or slippage.
2. Index Price
The index price is derived from the average price of the same asset across multiple major exchanges (e.g., BTC/USD from Binance, Coinbase, Kraken). It serves as a benchmark to prevent price manipulation and ensures fair valuation.
3. Mark Price
The mark price is a hybrid value based on the index price and often includes a small funding rate component. It’s used for calculating unrealized P&L and liquidation levels, helping avoid unnecessary liquidations due to temporary price spikes.
These three prices work together to maintain market integrity and ensure that funding fees accurately reflect market conditions.
Frequently Asked Questions (FAQ)
Q: Do I always have to pay funding fees?
A: No. You only pay or receive funding if you hold an open position when the fee is applied. Traders who close their positions before the 8-hour settlement window avoid the charge entirely.
Q: Can funding rates go negative?
A: Yes. A negative funding rate means shorts pay longs. This typically happens when the perpetual contract trades below the index price—often during bearish market sentiment.
Q: How are funding fees calculated?
A: The fee is calculated as: Position Value × Funding Rate. For example, if you hold $10,000 worth of a contract and the funding rate is 0.01%, you’ll pay or receive $1.
Q: Why do funding fees matter for traders?
A: Over time, recurring funding fees can significantly impact profitability—especially for large or long-held positions. Day traders might ignore them, but swing or carry traders must factor them into their cost structure.
Q: Is there a way to profit from funding rates?
A: Some advanced traders engage in funding rate arbitrage, taking opposite positions in spot and perpetual markets when funding rates are highly positive or negative. However, this requires careful risk management.
