On OKX, spot margin and perpetual contracts both let you trade with leverage, but the main difference lies in where the money comes from and what you pay to hold a position. Spot margin involves actually borrowing coins and paying interest. Perpetual contracts use margin trading without borrowing real coins; instead, long and short traders pay each other a funding fee.

Step 1: Check which account mode supports the product you need
OKX has four account modes, and not all of them support spot margin and futures.
- Case A: You only use spot margin, no futures: Switch to "Spot mode" or "Spot and futures mode". Spot mode itself does not support leverage. To borrow coins for long/short trades, you must use "Spot and futures mode" or the more advanced "Multi-currency margin mode".
- Case B: You only trade perpetual contracts, no margin borrowing: "Spot and futures mode" is enough. You can open perpetual contracts under isolated or single-currency cross margin.
- Case C: You want both spot margin and contracts, and want higher capital efficiency: Use "Multi-currency margin mode" or "Portfolio margin mode". These allow you to use all your account's coins as collateral. Spot margin debt and contract positions share the same margin pool, and profits and losses can offset each other. However, there is an asset threshold. For Multi-currency margin mode, your account equity must be at least 10,000 USD when you switch for the first time.
Step 2: Understand how borrowing interest works
Spot margin is essentially "borrowing money", so there is a clear interest cost, and it is charged every hour.
- What to do: Check the borrowing interest rate on the spot margin trading page.
- How to do it:
- Go to a spot trading pair page and switch to "Isolated margin" or "Cross margin" mode.
- When you enter the amount to borrow, the page shows the current "borrowing interest rate", usually a daily rate (e.g. 0.03%).
- Interest rule: Interest is calculated and collected once per hour. If you borrow at 22:55 and repay before 23:00, no interest is charged. If the loan remains after 23:00, the system will calculate and deduct interest for that hour.
- Completion standard: Know the current daily interest rate for the coin you want to borrow, and calculate how much interest you will pay for holding one day.
Common mistake: Many people only look at price changes and ignore the interest cost. If you hold a position for several days or weeks, accumulated interest can eat up a large part of your profit. Moreover, interest is automatically deducted from your account every hour. If the balance is insufficient, the system will force-liquidate part of your position to cover the interest, resulting in an unwanted reduction of your position.
Step 3: Understand how the funding fee is charged
Perpetual contracts do not involve real borrowing, so there is no interest. However, long and short traders pay each other a "funding fee" to keep the contract price close to the spot price.
- What to do: On the perpetual contract trading page, check the current "funding rate" and the next settlement time.
- How to do it:
- Open the perpetual contract trading interface. In the contract information bar, you can see the "funding rate" and a countdown to the next settlement.
- The funding fee settlement interval on OKX is not always 8 hours. Most contracts settle at 8:00, 16:00 and 24:00 (UTC+8), but some contracts settle every 1, 2 or 4 hours.
- After June 2026, the funding rate formula for different intervals has been adjusted: the 8-hour cycle rate remains unchanged, while the single rate for a 1-hour cycle is approximately 1/8 of the original.
- Calculation: Funding fee = Position value × Funding rate. When the rate is positive, longs pay shorts; when negative, shorts pay longs. The platform does not take any of this fee.
- Completion standard: Know the next settlement time and whether the rate is positive or negative, so you can tell if you will pay or receive money.
Risk note: If you hold a position for a long time, the funding fee acts like a regular drain every 8 hours (or shorter). When the market is very bullish, the rate may stay positive for a long time. Longs will have to pay shorts at every interval, which can significantly eat into profits over time. On the other hand, if you are short and the rate is negative, you will actually receive money. This cost is a continuous cash drain, similar in nature to spot margin interest, but calculated differently.

Step 4: Compare liquidation mechanisms
The conditions that trigger liquidation differ between the two products.
- Spot margin: Mainly looks at the "margin ratio". If it falls below a certain level, liquidation is triggered. The system will force-close your position to repay the debt and return any remaining collateral.
- Perpetual contracts: Liquidation is triggered when the "maintenance margin ratio ≤ 100%". However, OKX uses a partial liquidation system. It does not close the whole position at once. First, open orders are canceled, then the position is reduced step by step in tiers until the margin ratio is safe again. Besides the standard trading fee, a liquidation penalty is charged to cover slippage and any clawback loss during the process.
How to decide: If you only want to bet on the direction for a few hours to one day and do not care about the small differences between interest and funding fees, a perpetual contract is more straightforward. If you plan to hold for several days or more, first check the borrowing interest rate on the spot margin page, then check the funding rate on the contracts page, compare both costs, and then make your decision.
