What Are Perpetual Contracts?
Perpetual contracts, as the name suggests, are futures contracts without an expiration or settlement date. Unlike traditional futures that require position rollover or settlement weekly or monthly, perpetual contracts allow traders to hold positions indefinitely. To keep the contract price aligned with the underlying asset’s spot price, exchanges implement a mechanism called funding rate, which is settled periodically—on OKX, every 12 hours.
This funding mechanism ensures that long and short positions periodically pay each other based on market sentiment. When the market is bullish, longs typically pay shorts; when bearish, shorts pay longs. This balance helps prevent prolonged price divergence between the perpetual contract and the actual spot price.
OKX Perpetual Contract Fees: How Much Does It Cost Per Day?
Trading isn't free—and understanding the fee structure is key to maintaining profitability over time. On OKX, perpetual contract fees consist of two main components: taker fees and maker fees, along with periodic funding payments.
Maker and Taker Fees
- Maker fee: 0.015% to 0.02% (when you place a limit order that adds liquidity)
- Taker fee: 0.03% to 0.05% (when you place a market order that removes liquidity)
These rates may vary slightly depending on your 30-day trading volume and VIP tier, but the standard range remains consistent across major trading pairs like BTC/USDT and ETH/USDT.
Let’s assume you trade $10,000 worth of BTC/USDT perpetual contracts:
- As a maker, you’d pay between $1.50 and $2.00
- As a taker, you’d pay between $3.00 and $5.00
While these amounts seem small, frequent trading can accumulate significant costs over time—especially for scalpers or high-frequency traders.
Funding Fees: The Hidden Daily Cost
Funding fees are exchanged every 12 hours, specifically at 10:00 AM and 10:00 PM UTC. These are not direct exchange fees but payments between traders based on the prevailing funding rate.
You only pay or receive funding if you hold a position at the settlement moment.
The formula for funding payment is:
Funding Payment (in USD) = Face Value × Number of Contracts × Funding Rate
The funding rate itself is calculated using:
Funding Rate = Clamp(MA((Future Mid Price – Spot Index Price) / Spot Index Price + Interest), -0.25%, 0.25%)
Where:
- Clamp limits the rate between -0.25% and +0.25%
- MA refers to the moving average over a specific window
- Interest is the base interest rate (usually minimal in crypto)
If the funding rate is positive, long position holders pay short position holders.
If it's negative, short holders pay longs.
For example, if the funding rate is 0.01%, a trader holding $10,000 worth of long position would pay $1 in funding every 12 hours—or $2 per day.

How to Calculate Profit and Loss on OKX Perpetual Contracts
Understanding P&L (Profit & Loss) is vital for evaluating trade performance and managing risk effectively. On OKX, there are two types of P&L: realized and unrealized.
Realized Profit and Loss
Realized P&L reflects gains or losses from closed positions. It becomes "locked in" once you exit part or all of your trade.
For Long (Buy) Positions:
Realized P&L = (Contract Value / Entry Price – Contract Value / Exit Price) × Number of Contracts Closed
Example:
A trader opens a long position at $50,000/BTC**, with a contract value of $100 per contract. They buy 2 contracts and later sell 1 at $100,000/BTC**.
= ($100 / $50,000 – $100 / $100,000) × 1
= (0.002 – 0.001) = 0.001 BTC profit
For Short (Sell) Positions:
Realized P&L = (Contract Value / Exit Price – Contract Value / Entry Price) × Number of Contracts Closed
Example:
Same contract value ($100), trader opens short at **$50,000/BTC with 10 contracts, then buys back 8 at $100,000/BTC**.
= ($100 / $100,000 – $100 / $50,000) × 8
= (0.001 – 0.002) × 8 = –0.8 BTC loss
This shows how incorrect timing or over-leveraging can lead to substantial losses even in volatile markets.
Unrealized Profit and Loss
Unrealized P&L shows the current value of open positions based on the latest market price (or mark price).
For Long Positions:
Unrealized P&L = (Contract Value / Entry Price – Contract Value / Mark Price) × Current Position Size
Example:
Trader buys 6 BTC contracts at $50,000/BTC (contract value $100). Current mark price is $60,000/BTC.
= ($100 / $50,000 – $100 / $60,000) × 6
= (0.002 – 0.001666...) × 6 ≈ +2 BTC unrealized profit
For Short Positions:
Unrealized P&L = (Contract Value / Mark Price – Contract Value / Entry Price) × Current Position Size
This metric helps traders assess risk exposure in real-time and decide when to exit or adjust their positions.
Frequently Asked Questions (FAQ)
Q: How often are funding fees charged on OKX perpetual contracts?
A: Funding fees are charged every 12 hours—at 10:00 AM and 10:00 PM UTC. You only pay or receive funding if you hold a position at those exact times.
Q: Do I always have to pay fees when trading perpetual contracts?
A: Yes, taker and maker fees apply on every trade execution. However, makers usually enjoy lower fees due to providing market liquidity.
Q: Can I avoid paying funding fees?
A: Yes—by closing your position before the funding timestamp (e.g., just before 10:00 AM or PM UTC). Some traders use this strategy during periods of high positive funding rates.
Q: Is the funding rate predictable?
A: While not guaranteed, funding rates tend to correlate with market sentiment. High leverage in long positions often leads to positive funding rates.
Q: How does leverage affect my fees and P&L?
A: Leverage doesn’t directly impact trading fees but magnifies both gains and losses in your P&L calculations. Higher leverage increases liquidation risk.
Q: Where can I view live funding rates on OKX?
A: Funding rates are displayed directly on the trading interface for each perpetual contract, typically near the order book or market data panel.
