In the world of cryptocurrency trading, futures contracts are essential tools for hedging and speculation. They primarily fall into two categories: quarterly futures (delivery contracts) and perpetual contracts. Understanding their differences is crucial for optimizing your trading strategy and managing costs.
What Are Quarterly Futures and Perpetual Contracts?
Quarterly Futures (Delivery Contracts) have a fixed expiration date. Upon maturity, the contract must be settled or closed, regardless of whether the position is profitable. This structure is similar to traditional futures contracts.
Perpetual Contracts, as the name suggests, have no expiration date. Traders can hold positions indefinitely, provided they maintain sufficient margin to avoid liquidation. This flexibility makes them popular among crypto traders.
Many beginners wonder: which contract type is more suitable for my trading style? Which one offers better cost efficiency? This article breaks down the key differences to help you make informed decisions.
Key Difference 1: Funding Rates
From a transaction fee perspective, both contract types are similar. For instance, on major exchanges, maker and taker fees are often identical. The primary cost difference lies in funding rates.
Understanding Funding Rates
Funding rates are a mechanism unique to perpetual contracts. They ensure the contract price remains anchored to the spot market price. Periodically (typically every 8 hours), funding fees are exchanged between long and short traders based on the funding rate.
- If the funding rate is positive, long positions pay short positions.
- If the funding rate is negative, short positions pay long positions.
The formula for calculating funding fees is:
Funding Fee = Position Value × Funding RateWhere:
Position Value = Number of Contracts × Contract Face Value × Mark PriceWhy Funding Rates Matter
In trending markets, where one side (long or short) dominates, traders on the dominant side often pay funding fees. This can significantly increase trading costs. For example:
Suppose you hold a short position of 1000 ETH perpetual contracts, with a face value of 0.1 ETH per contract and a mark price of $1800. If the funding rate is -0.004%, you would pay:
Position Value = 1000 × 0.1 × 1800 = 180,000 USDT
Funding Fee = 180,000 × 0.004% = 7.2 USDTThis fee is deducted from your available balance or margin, potentially increasing liquidation risk if margins are tight.

Key Difference 2: Trading Flexibility
Quarterly Futures require mandatory settlement upon expiration. If your position is underwater at expiration, you must close it, potentially realizing a loss. This limits your ability to "wait out" unfavorable market conditions.
Perpetual Contracts offer greater flexibility. You can hold positions as long as you maintain adequate margin, allowing you to manage trades according to your strategy without time constraints.
Key Difference 3: Pricing Mechanisms
The price used to calculate profits, losses, and liquidation levels varies between contract types and exchanges. Most platforms use a mark price system to prevent market manipulation and reduce liquidation risks from abnormal price spikes (e.g., "wick" events).
What Is Mark Price?
Mark price is a synthetic price derived from spot index prices and moving averages of basis differences. It is less susceptible to short-term market manipulation or liquidity issues than the last traded price.
For example:
- If BTC spot price is stable, but a fleeting sell-off causes a futures contract to dip briefly, the mark price would remain relatively stable, protecting traders from unjust liquidation.
Both perpetual and quarterly futures use mark prices, but the calculation may differ slightly due to varying basis adjustments. For instance, ETH perpetual and quarterly contracts might have slightly different mark prices at the same time.
Key Difference 4: Risk Management Models
Quarterly Futures on some exchanges use a "socialized loss" mechanism. If a trader’s losses exceed their margin (a "clawback" event), profitable traders share the loss. This can impact your earnings unexpectedly.
Perpetual Contracts typically use an automatic deleveraging system or insurance funds to cover losses, avoiding socialized losses. This provides more predictable risk management.
Which Contract Is More Cost-Effective?
The answer depends on your trading style, market conditions, and risk tolerance.
- In trending markets, perpetual contracts may incur higher funding costs, eroding profits. Quarterly futures might be preferable for longer-term positions.
- If you have ample margin, perpetual contracts offer greater flexibility to hold positions through volatility.
- For short-term trades, perpetual contracts are often more convenient due to no expiration.

Frequently Asked Questions
Q1: Do perpetual contracts always have funding fees?
A: Yes, funding fees are exchanged periodically. However, the direction (who pays) depends on the funding rate, which reflects market sentiment.
Q2: Can I avoid funding fees in perpetual contracts?
A: No, but you can monitor funding rates and adjust your position timing to minimize costs. Some traders avoid holding positions during funding intervals.
Q3: Which contract type is better for beginners?
A: Perpetual contracts are simpler due to no expiration, but funding fees add complexity. Quarterly futures may be easier for those familiar with traditional futures.
Q4: How often are funding rates applied?
A: Typically every 8 hours, but this varies by exchange. Check your platform’s schedule.
Q5: Can mark price prevent liquidation entirely?
A: No, but it reduces the risk of liquidation from abnormal price movements. Always monitor your margin levels.
Q6: Are there exchanges without socialized losses for quarterly futures?
A: Yes, some platforms use insurance funds instead. Research your exchange’s policy before trading.
Conclusion
Both quarterly futures and perpetual contracts have distinct advantages and drawbacks. Your choice should align with your trading goals, risk management strategy, and market outlook. Perpetual contracts offer flexibility but may incur funding costs, while quarterly futures provide fixed timelines but require mandatory settlement.
By understanding these differences, you can optimize your trading approach and manage costs effectively. Always prioritize risk management and stay informed about market mechanisms.
