Perpetual contracts, as the name suggests, are designed to last indefinitely without an expiration or settlement date. Unlike traditional futures contracts that settle weekly or monthly, perpetual contracts use a daily (or even twice-daily) funding mechanism to keep the contract price aligned with the underlying spot market. One of the most prominent platforms offering this derivative product is OKX, a leading global cryptocurrency exchange.
If you're considering trading perpetual contracts on OKX, understanding the fee structure—especially how much it costs per day—is essential for managing your trading costs and maximizing profitability. This guide breaks down everything you need to know about OKX perpetual contract fees, funding rates, and profit-and-loss calculations in clear, actionable detail.
Understanding OKX Perpetual Contract Trading Fees
When trading perpetual contracts on OKX, there are two primary types of transaction fees: maker fees and taker fees.
- Maker Fee: Applies when you place a limit order that adds liquidity to the order book.
- Taker Fee: Charged when you place a market order (or any order that removes liquidity).
On OKX, these fees typically range as follows:
- Maker fee: Between 0.015% and 0.02%
- Taker fee: Between 0.03% and 0.05%
These rates can vary slightly depending on your 30-day trading volume and whether you’re using a discount program (such as holding certain tokens). However, for most standard users, the above ranges represent the baseline cost per trade.

It's important to note that these fees are charged per trade, not per day. So if you open and close a position once in a day, you’ll pay both a maker/taker fee upon entry and another upon exit. Frequent traders should factor this into their cost-per-day estimates.
Daily Funding Rates: The Hidden Cost of Holding Positions Overnight
While trading fees apply only when you execute trades, funding fees are what make perpetual contracts truly "daily" in cost. These are periodic payments exchanged between long and short position holders every 8 or 12 hours, depending on the specific contract.
On OKX, funding is settled every 12 hours, at approximately 10:00 UTC and 22:00 UTC, right after the mark price is recalculated.
How Funding Fees Work
You only pay or receive funding if you hold a position at the time of settlement. If you close your position before the funding timestamp, you avoid the charge entirely.
The funding payment is calculated using this formula:
Funding Payment (in USD) = Face Value × Number of Contracts × Funding Rate
The direction of the payment depends on the sign of the funding rate:
- If the funding rate is positive, longs pay shorts
- If the funding rate is negative, shorts pay longs
This mechanism helps align the perpetual contract price with the spot market. When the contract trades at a premium to spot, funding turns positive to incentivize selling pressure. When it trades at a discount, funding goes negative to encourage buying.
How Is the Funding Rate Calculated?
OKX uses a transparent formula based on market conditions:
Funding Rate = Clamp(MA((Mark Price – Index Price) / Index Price + Interest), –0.25%, 0.25%)
Let’s break that down:
- Mark Price: The fair value of the contract, adjusted to prevent manipulation.
- Index Price: The average spot price from major exchanges.
- Interest: A small fixed rate (usually 0.01% daily).
- MA: Moving average over a defined period.
- Clamp: Ensures the rate stays within ±0.25% bounds.
In practice, funding rates rarely hit these extremes. Most commonly, they range between –0.01% and +0.01%, meaning a $10,000 position might incur a daily cost (or gain) of around **$1–$2**.
How to Estimate Total Daily Costs
To estimate your total daily cost of holding a perpetual contract on OKX, consider both one-way trading fees and funding payments.
Example Scenario:
- Trade size: $5,000
- Entry: Taker fee at 0.05%
- Exit: Taker fee at 0.05%
- Funding rate: +0.01% per session (twice daily)
Daily cost breakdown:
- Trading fees: $5,000 × 0.05% × 2 (entry + exit) = **$5**
- Funding fees: $5,000 × 0.01% × 2 sessions = **$1**
Total estimated daily cost: $6, or 0.12% of position size
Keep in mind: active traders may experience higher costs due to frequent entries/exits, while swing traders benefit from lower relative fees but must monitor funding trends closely.

Calculating Profits and Losses on OKX Perpetual Contracts
Understanding how profits and losses are calculated is crucial for evaluating performance and managing risk.
Realized P&L (After Closing a Position)
This reflects actual gains or losses once you close part or all of your position.
For Long Positions (Buy to Open, Sell to Close):
Realized P&L = (Contract Value / Entry Price – Contract Value / Exit Price) × Number of Contracts
Example:
You buy 2 BTC perpetual contracts at $50,000 each (contract value = $100).
Later, you sell 1 contract at $60,000.
= ($100 / $50,000 – $100 / $60,000) × 1
= (0.002 – 0.001667) = +0.000333 BTC profit
For Short Positions (Sell to Open, Buy to Close):
Realized P&L = (Contract Value / Exit Price – Contract Value / Entry Price) × Number of Contracts
Example:
You short 5 ETH contracts at $3,000 (value = $10 per contract).
Later, you buy back 3 contracts at $2,500.
= ($10 / $2,500 – $10 / $3,000) × 3
= (0.004 – 0.003333) × 3 = +0.002 BTC profit
Unrealized P&L (While Still Holding)
This shows current gains or losses 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
These values update in real time and affect your available margin and liquidation risk.

Frequently Asked Questions
Q: How often does OKX charge funding fees?
A: OKX charges funding fees every 12 hours—at approximately 10:00 UTC and 22:00 UTC. You only pay or receive funding if you hold a position at the exact settlement time.
Q: Can I avoid paying funding fees?
A: Yes. Simply close your position before the next funding timestamp. Many traders use this strategy during periods of high positive funding to avoid recurring costs.
Q: Are maker fees lower than taker fees on OKX?
A: Yes. Maker orders (limit orders that add liquidity) have lower fees—typically 0.015%–0.02%—compared to taker orders (market orders), which cost 0.03%–0.05%.
Q: What happens if I don’t have enough balance for funding payments?
A: If your account lacks sufficient funds, OKX will deduct the amount from your unrealized P&L or margin balance. In extreme cases, this could increase liquidation risk.
Q: Do funding rates predict market direction?
A: Not directly. High positive funding often indicates bullish sentiment (more longs), but it can also signal over-leverage and potential reversals. Use it as one tool among many for analysis.
Q: Is OKX safe for perpetual contract trading?
A: OKX is one of the most established crypto exchanges globally, with strong security measures including cold storage, two-factor authentication, and a proof-of-reserves system.
