Opening a position without checking the funding rate is like driving without checking the fuel gauge—you only find out the cost later. Especially for your first order, do not only stare at the candlesticks. First understand how to check and calculate this fee that settles every 8 hours.
What Is the Funding Rate? It Is Not a Fee Paid to the Exchange
It is a "balancing fee" paid between long and short traders in perpetual contracts. When the rate is positive, longs pay shorts. When it is negative, shorts pay longs.
Core logic: Its purpose is to pull the perpetual contract price back near the spot price. You are not paying the platform. You are balancing market forces between longs and shorts.
Step 1: Find the Current Funding Rate Before Opening
What to do: Confirm the current funding rate and the next settlement time.
How to do it (App/Web): Go to the perpetual trading page, such as BTC-USDT. Near the candlestick chart, look for the "Funding Rate" label (or "资金费率" on the Chinese interface). Tap it to see the current rate, the countdown to the next settlement, and historical funding rate trends.
Done when: You clearly see a number like "+0.01%" or "-0.02%" and a countdown like "X hours X minutes until the next settlement."
Step 2: Estimate How Much You Will Pay
Do not skip this. Calculate before you open.
Formula:
Funding fee = position notional value × funding rate Position notional value = entry price × contract quantity = margin × leverage
Example: You use 100 USDT margin with 10x leverage, so your position notional value is 1,000 USDT. If the current funding rate is +0.01% (longs pay shorts) and you open a long, each settlement deducts: 1,000 × 0.01% = 0.1 USDT
That does not look like much, but it settles 3 times a day. Holding for a week is about 2.1 USDT—about 2.1% of your margin. In extreme cases, when the rate spikes to -0.5% or higher, the fee impact is much bigger.
Step 3: Include the Funding Rate in Your Profit and Loss
What to do: When placing an order, check the "Entry Price" and "Estimated Liquidation Price" on the trading page. Those already include trading fees, but they do not include funding fees. You must keep that in mind—the longer you hold, the more the accumulated charges can grow.
Settlement Time: Most Coins Settle Every 8 Hours
OKX perpetual contracts usually settle the funding rate every 8 hours (UTC 00:00, 08:00, 16:00, which is 08:00, 16:00, and 00:00 in UTC+8). Some special contracts may adjust the frequency, for example MEUSDT was changed to every 4 hours.
Key point: You only pay or receive the fee if you are still holding at the settlement moment. If you close before settlement, you do not pay that round of fees.
Common Mistake: Forcing a Long at a Very High Funding Rate
You see a very high rate, such as 0.1%, and think "market sentiment is this hot, so it will keep rising." You rush in and go long. The price may rise a little, but after three days the funding fees eat up all your profit. A very high rate shows that long sentiment is already extremely crowded—risk is often right in front of you.
Risk Warning: Long-Term Holding Costs More Than You Think
The funding rate is not huge by itself, but multiplied by time and leverage, it becomes more significant than you expect. For perpetual contracts, one of the core costs of holding long term is the repeated settlement of the funding rate.
Suppose you hold a 10,000 USDT long position with a funding rate of 0.03%. You pay 3 USDT every 8 hours, 9 USDT per day, and about 270 USDT per month—an annualized cost close to 33%. That is not just losing money; it is giving money away to shorts.
How to Verify After You Open
After your order is filled, go to the "Positions" page. In the position details, look for fields like "Funding Rate" or "Estimated Deduction". If they display normally, you have entered the funding settlement cycle. Go to "Order History" or "Trade Records" → "Funding Fees" to see how much was deducted or paid for each settlement.
