Perpetual contracts have become one of the most popular instruments in the cryptocurrency derivatives market, largely due to their unique mechanism that keeps them closely aligned with the underlying asset’s spot price. A key component of this alignment is the funding rate—a periodic fee exchanged between traders holding long or short positions. This article explains how funding rates work, how they are calculated, and why they matter for traders engaging in perpetual futures trading.
Whether you're a beginner exploring crypto derivatives or an experienced trader optimizing your strategy, understanding funding rates can help you manage costs and improve timing in your trades.

What Are Funding Rates?
Funding rates are periodic payments made between long and short traders in perpetual contracts to ensure that the contract price stays close to the spot market price of the underlying asset. Unlike traditional futures contracts, perpetual contracts do not have an expiration date, so this mechanism prevents the contract from deviating too far from its fair value over time.
These payments occur every 8 hours, at set intervals (typically 00:00 UTC, 08:00 UTC, and 16:00 UTC). Importantly:
- You only pay or receive funding if you hold a position at the moment the funding is settled.
- If you close your position before the funding timestamp, you are not subject to any funding fee.
This means active traders who open and close positions within the 8-hour window can often avoid funding costs entirely—making timing a strategic factor in short-term trading.
Who Pays and Who Receives?
The direction of the funding flow depends on the sign of the funding rate:
- 🔹 Positive funding rate (e.g., +0.01%): Longs pay shorts
- 🔹 Negative funding rate (e.g., -0.01%): Shorts pay longs
This system balances market sentiment. When more traders are bullish and open long positions, demand pushes the perpetual contract price above the spot price (a state known as contango), leading to positive funding rates. This incentivizes traders to take short positions or close longs, bringing the price back in line.
Conversely, when bearish sentiment dominates and shorts outnumber longs, the contract trades below spot (backwardation), resulting in negative funding rates—rewarding long holders and encouraging short covering.
Note: Funding is based on the nominal value of your position, not your margin or leverage. For example, if you hold $100 worth of BTC/USDT perpetual contracts, your funding will be calculated on $100—regardless of whether you're using 2x or 50x leverage.
How Is the Funding Rate Calculated?
The primary goal of the funding rate is to anchor the perpetual contract price to the real-world spot price. To achieve this, exchanges use a formula that considers two main components: the interest rate component and the premium component.
In most systems, including advanced platforms, the funding rate is derived from:
Funding Rate = Premium Rate + Clamp(Interest Rate)However, many exchanges—including those following similar models—use a simplified approach focusing on premium-based calculation.
Key Elements in Funding Rate Calculation
Arithmetic Moving Average (MA) of Premium
The premium is the difference between the perpetual contract price and the index (spot) price, expressed as a percentage. To smooth out volatility, platforms typically use a 60-minute arithmetic average (MA) of this premium to determine the next funding rate.
For example:
- If BTC’s perpetual contract consistently trades 0.5% above its spot index over the past hour, the average premium will reflect this upward bias.
- The system interprets this as excessive bullish pressure and adjusts the funding rate upward—making it costlier to hold longs.
Adjustment Coefficient
Different contracts may have varying tick sizes or liquidity levels, which can distort the premium measurement. To correct for these discrepancies, an adjustment coefficient is applied.
Currently, for most major contracts, this coefficient is set to 1, meaning no additional scaling is applied. However, it may be adjusted dynamically based on market conditions without prior notice—ensuring accuracy across diverse trading pairs.

Who Collects the Funding Fee?
One of the most trader-friendly aspects of modern perpetual markets is that exchanges do not profit from funding fees. Instead, these payments are transferred directly between users:
- Longs pay shorts (or vice versa) through a peer-to-peer redistribution model.
- The exchange acts solely as a facilitator, ensuring accurate calculation and seamless settlement.
This transparency helps maintain trust and fairness in the marketplace, especially during periods of extreme volatility when funding rates can spike significantly.
When Are Funding Fees Applied?
As mentioned earlier, funding occurs every 8 hours, typically at:
- 00:00 UTC
- 08:00 UTC
- 16:00 UTC
At each of these timestamps:
- The system calculates the final funding rate.
- It checks which users have open positions.
- Payments are settled instantly—either credited to or debited from your wallet.
It’s important to note:
- Positions closed before the settlement time avoid funding.
- Partial closures still leave you liable for the remaining portion.
- Funding is usually deducted from unrealized PnL or account equity automatically.
Frequently Asked Questions (FAQ)
Q: Can I avoid paying funding fees?
Yes. If you close your position before the 8-hour funding timestamp (e.g., 00:00, 08:00, or 16:00 UTC), you won't be charged or receive any funding. Day traders often use this to their advantage.
Q: Does leverage affect funding costs?
No. Funding is calculated based on the nominal value of your position, not your margin or leverage level. Whether you use 2x or 50x leverage, the fee remains proportional to your position size.
Q: Why do funding rates change so frequently?
Funding rates adjust hourly based on market conditions—especially price divergence between perpetual contracts and spot indices. High demand for longs increases positive rates; strong shorting pressure leads to negative rates.
Q: Are funding rates predictable?
While exact values aren't guaranteed, most platforms display an estimated next rate. Traders can monitor trends and anticipate shifts—especially around major news events or price breakouts.
Q: What happens if I’m under liquidation during funding?
If your position is liquidated before the funding interval, you won’t pay or receive funding. Settlement only applies to active positions at the exact moment of disbursement.
Q: Is there a cap on how high funding rates can go?
Some exchanges implement caps or smoothing mechanisms to prevent extreme swings. However, during high volatility (like flash crashes or rallies), rates can briefly spike to several percent annually.
Final Thoughts
Understanding funding rates is essential for anyone trading perpetual contracts. It's not just about cost—it's about reading market sentiment, timing entries and exits, and avoiding unexpected fees.
By monitoring live funding data, you gain insight into whether the market is dominated by bulls or bears. Positive rates suggest aggressive long positioning; negative ones signal bearish control. Smart traders use this information not only to reduce expenses but also to inform directional bias.
Whether you’re hedging exposure or speculating on price moves, mastering the mechanics behind funding ensures you stay ahead in fast-moving crypto markets.
