Fee Structure Details on OKX

·

Understanding the fee structure of a cryptocurrency exchange is essential for traders aiming to maximize returns and minimize costs. On OKX, trading fees are not fixed—they vary based on user activity, asset holdings, and token ownership. This dynamic system rewards active and high-volume traders with lower fees and higher benefits. In this guide, we’ll break down how OKX determines your trading fee rate, account tier, 30-day trading volume calculation, asset snapshot rules, and withdrawal limits, all while integrating key SEO-friendly terms like trading fees, VIP levels, OKB holdings, 30-day trading volume, maker-taker fees, withdrawal limits, and account tiers.

How OKX Determines Your Fee Tier

OKX categorizes users into Regular and Professional based on their trading behavior and asset size. Each category has its own criteria for determining the user’s fee tier, which directly affects the trading fees applied across spot, futures, perpetual, and options markets.

The system automatically selects the highest applicable tier from all qualifying metrics—spot trading volume, delivery contract volume, perpetual contract volume, options trading volume, and total assets. This ensures users always benefit from the most favorable rate.

For example:

Despite mixed levels across different products, the user will be upgraded to VIP 4, enjoying the lowest maker and taker fees across all trading pairs and derivatives.

Understanding OKB Holdings

Your OKB total holding plays a crucial role if you're classified as a regular user. It includes the sum of OKB tokens held in your:

Please note: OKB stored in Savings (formerly "Residual Coin Treasure") is currently not counted toward tier eligibility.

Holding more OKB can significantly reduce your trading fees, increase withdrawal limits, and grant access to exclusive features—making it a strategic asset for long-term users.

Sub-Accounts and Tier Inheritance

For users managing multiple accounts, OKX supports a parent-child account structure.

This allows teams or institutional traders to centralize tier management while maintaining separate operational accounts.

How 30-Day Trading Volume Is Calculated

OKX uses a precise method to calculate your 30-day trading volume across all markets:

  1. Each trade is converted into BTC value based on the BTC price at the time of execution—even trades in USDT, ETH, or other pairs.
  2. The daily BTC total is then converted to USD using the BTC/USD mid-price:
    (Daily Open Price + Daily Close Price) / 2
  3. These values roll over every 24 hours (at Hong Kong time 00:00), maintaining a continuous 30-day window.

For instance, if you traded OMG, XUC, BTC, LTC, and BCH over the past month, each transaction would be:

This standardized approach ensures fairness and consistency across global markets.

Asset Snapshot and Valuation Method

Your asset volume is another key factor for professional-tier users. Here’s how it's assessed:

This means only your actual owned assets count—not leveraged positions.

Maker vs. Taker Fee Rules

OKX applies a standard maker-taker model:

Fee Deduction Rules:

Negative Maker Fee (Rebate) Policy:

When makers receive rebates (negative fees), the rebate currency matches the taker’s fee currency:

This alignment prevents currency mismatch and simplifies accounting for active traders.

Daily Withdrawal Limits by Tier

Your fee tier also determines your daily withdrawal limit, calculated in USD equivalent:

All withdrawals—regardless of coin—are converted into USD using real-time exchange rates at the time of request. The total cannot exceed your tier’s daily cap.

Example:

A user at Level 1 has a $10 million daily limit.
They withdraw:

A subsequent request to withdraw $5 million in XRP would be rejected.

⚠️ Note: Withdrawal capacity is also constrained by KYC level:

  • KYC Level 1: ≤ $500,000 per 24 hours
  • KYC Level 2: ≤ $10 million per 24 hours

Users needing higher limits must contact customer support for manual review.

Frequently Asked Questions (FAQ)

Q: How often are fee tiers updated?

A: Fee tiers are recalculated daily at 00:00 Hong Kong time based on the previous 30 days’ trading volume, current asset snapshot, and OKB holdings.

Q: Does borrowing assets affect my fee tier?

A: No. Only owned assets (excluding borrowed funds from margin or lending) are included in the asset snapshot used for tier calculation.

Q: Can I upgrade my tier instantly by buying OKB?

A: Yes. Increasing your OKB holdings can immediately qualify you for a higher tier if you're a regular user. For professional users, boosting trading volume or assets under management will help.

Q: Are futures and spot volumes combined?

A: Yes. All product lines—spot, delivery contracts, perpetual swaps, and options—are evaluated separately, and the highest qualifying tier is applied across all services.

Q: Why did my withdrawal fail even though I’m under my tier limit?

A: Your KYC verification level imposes an additional hard cap. Even with a high-tier account, KYC1 users cannot withdraw more than $500,000 per day.

Q: Do sub-accounts need separate verification?

A: Sub-accounts inherit the parent’s tier but may require individual KYC verification depending on jurisdiction and functionality enabled.
