Cryptocurrency derivatives trading has become increasingly popular, with perpetual futures contracts leading the charge. Among the top platforms facilitating this trend is OKX, a globally recognized digital asset exchange offering a wide range of services including spot trading, margin trading, options, and advanced derivatives. One of the most frequently asked questions by traders — especially those new to futures — is: How are OKX contract trading fees calculated?
This comprehensive guide breaks down the fee structure, explains key concepts like taker/maker fees and funding rates, and walks you through profit calculations and essential trading steps — all while keeping things clear, accurate, and optimized for real-world use.

Understanding OKX Contract Fee Structure
At its core, OKX uses a taker-maker fee model for perpetual and futures contracts. This system incentivizes liquidity provision by rewarding users who place limit orders (makers) and charging slightly more from those who execute against existing orders (takers).
Maker vs. Taker Fees
- Maker Fees: Users placing limit orders that add liquidity to the order book are charged lower fees — typically between 0.015% and 0.02%.
- Taker Fees: Users placing market orders or aggressive limit orders that remove liquidity pay higher fees — generally ranging from 0.03% to 0.05%.
These rates may vary slightly depending on your trading volume, VIP tier, or ongoing promotions. High-volume traders can qualify for reduced fees and even negative maker fees (where you earn rebates for adding liquidity).
It's important to note that these fees apply only at the time of opening or closing a position — there are no hidden charges beyond this base structure.
What Are Funding Rates and When Are They Charged?
Perpetual contracts on OKX do not have an expiration date, but they use a mechanism called funding rate to keep the contract price aligned with the underlying spot market.
Key Facts About Funding Rates:
- Funding is exchanged every 12 hours, precisely at 10:00 AM and 10:00 PM UTC.
- Only traders holding positions at these moments are involved in the payment.
- If the funding rate is positive, long (buy) position holders pay short (sell) holders.
- If the rate is negative, short position holders pay longs.
The formula used to calculate funding is:
Funding Payment = Nominal Value × Funding Rate
Where:
- Nominal Value = Face value per contract × Number of contracts
- Funding Rate = Clamp(MA((Mark Price - Index Price)/Index Price + Interest Rate), -0.25%, 0.25%)
This "clamping" ensures extreme volatility doesn’t lead to excessive payments — capping rates at ±0.25%.

Calculating Realized and Unrealized P&L
Understanding profit and loss (P&L) is crucial for managing risk and evaluating performance.
Realized P&L (When You Close a Position)
This reflects actual gains or losses after closing part or all of a position.
For Long Positions (Buy to Open):
Realized P&L = (Contract Value / Entry Price – Contract Value / Exit Price) × Number of Contracts
Example:
You open a long position on BTC/USDT at $50,000 with 2 contracts (face value $100 each). Later, you close 1 contract at $100,000.
P&L = (100 / 50,000 – 100 / 100,000) × 1 = (0.002 – 0.001) = 0.001 BTC profit.
For Short Positions (Sell to Open):
Realized P&L = (Contract Value / Exit Price – Contract Value / Entry Price) × Number of Contracts
Example:
You short 10 BTC contracts at $50,000 and later buy back 8 contracts at $100,000.
P&L = (100 / 100,000 – 100 / 50,000) × 8 = (0.001 – 0.002) × 8 = -0.8 BTC (loss).
Unrealized P&L (Open Positions)
This shows current gains or losses on open trades based on the latest market price.
For Longs:
Unrealized P&L = (Contract Value / Entry Price – Contract Value / Mark Price) × Position Size
For Shorts:
Unrealized P&L = (Contract Value / Mark Price – Contract Value / Entry Price) × Position Size
Mark price is used instead of last traded price to prevent manipulation and ensure fair liquidation pricing.
Step-by-Step: How to Start Trading Contracts on OKX
Ready to dive in? Here’s how to begin trading futures contracts on OKX:
Step 1: Log In and Navigate to Derivatives
After logging into your OKX account, go to the [Trading] section and select Perpetual Contracts or Futures, depending on your preference.
Step 2: Transfer Funds
Move assets from your funding wallet to your derivatives trading account. Choose the coin (e.g., USDT or BTC), enter the amount, and confirm.
Step 3: Select Your Market
Use the search bar to find your desired trading pair — such as BTC-USDT or ETH-USDC — and pick the contract type (e.g., USDT-margined or coin-margined).
Step 4: Choose Leverage Mode
Decide between Cross Margin (shared margin across positions) or Isolated Margin (dedicated margin per position). Adjust leverage using the slider — commonly set between 5x to 125x depending on risk tolerance.
Step 5: Place Your Order
Choose:
- Buy Open Long if you expect prices to rise
- Sell Open Short if you anticipate a drop
Enter order type (limit/market), price, size, and submit.
Step 6: Monitor and Close
Track your position under the Positions tab. Watch margin ratio closely — if it drops too low, you risk liquidation. When ready, place an opposite order to close your trade.
Frequently Asked Questions
Q: Are there any withdrawal or deposit fees for contract trading?
A: Depositing funds to your OKX account is usually free for most cryptocurrencies. Withdrawal fees vary by blockchain but are clearly listed before confirmation. There are no additional fees specific to using the contract trading function.
Q: Does OKX charge fees for closing positions?
A: Yes — closing a position incurs either a maker or taker fee, just like opening one. The rate depends on whether your closing order adds or removes liquidity.
Q: How can I reduce my trading fees on OKX?
A: You can lower fees by increasing your 30-day trading volume to qualify for VIP tiers, using referral programs (if available), or participating in campaigns that offer fee rebates.
Q: What happens if I hold a position during funding time?
A: If you have an open position when funding occurs (at 10:00 or 22:00 UTC), you’ll either pay or receive funds based on the current funding rate and your position direction.
Q: Can I avoid paying funding fees?
A: Yes — simply close your position before the next funding timestamp. However, this should not be the sole reason for exiting a trade; always prioritize your strategy over fee avoidance.
