OKX Contract Fees: Maker & Taker Rates Explained flowchart

How are contract trading fees calculated?

OKX classifies users into regular and professional categories based on trading volume. Regular users are tiered according to OKB holdings, while professional users are tiered according to total asset size and 30‑day trading volume. Each tier determines the next‑day contract fee, with separate rates for maker (order‑placement) and taker (order‑taking) actions.

If a user meets different tier conditions across multiple product lines (spot, perpetual contracts, delivery contracts, options, and spread strategies), the system applies the highest tier discount. For example, if a user’s spot trading volume qualifies for VIP 2, perpetual contracts qualify for VIP 3, options qualify for VIP 1, spread strategies qualify for VIP 2, and total assets qualify for VIP 4, the user will receive VIP 4 rates across all product lines.

1. Fee calculation formulas

Regular user (lv1): taker fee 0.05 %, maker fee 0.02 %
Coin‑denominated contracts
Opening fee = contract value × number of contracts opened ÷ opening price × fee rate
Closing fee = contract value × number of contracts closed ÷ closing price × fee rate
USDT‑denominated contracts
Opening fee = contract value × number of contracts opened × opening price × fee rate
Closing fee = contract value × number of contracts closed × closing price × fee rate

Example

Coin‑denominated BTC contract, opening price 10,000 USDT, quantity 100 contracts, tier 1 (taker). Fee = 100 × 100 ÷ 10,000 × 0.0005 = 0.0005 BTC.
USDT‑denominated BTC contract, opening price 10,000 USDT, quantity 100 contracts, tier 1 (taker). Fee = 100 × 0.01 × 10,000 × 0.0005 = 5 USDT.

3. Key concept definitions

1. Total OKB holdings

When calculating this metric, include OKB balances held in the main account, sub‑accounts, spot wallets, and margin wallets. Assets held in “Earn”‑type products are not counted.

2. Parent‑child account explanation

The parent‑account tier is determined by the cumulative 30‑day trading volume of all its sub‑accounts together with the parent’s OKB holdings. A newly created sub‑account inherits the parent’s fee tier after 24:00 (Hong Kong Time) on the day of creation.

3. 30‑day trading volume

Contract trading volume is first converted to BTC using the prevailing USD‑BTC price, then converted to USD using the daily BTC/USD mid‑price ((open + close) / 2). The system settles at 00:00 UTC each day and aggregates the most recent 30 days.

4. Maker vs. taker

Maker: An order placed at a specific price that does not execute immediately; it waits for a counter‑party to match it, incurring a maker fee.
Taker: An order executed instantly at market price or against an existing maker order, incurring a taker fee.

5. Liquidation fee

Charged at the user’s current taker fee rate.

6. Daily withdrawal limit

The platform calculates a daily USD withdrawal allowance based on the user’s fee tier. All cryptocurrency withdrawals are converted to USD at the prevailing exchange rate and must not exceed this allowance. The limit is also subject to KYC/verification level.

Example

A user’s daily withdrawal cap is 300 USD. They have already withdrawn 250 USD + 25 USD (OMG) + 15 USD (XRP) = 290 USD, leaving 10 USD remaining. If they then request an additional 20 USD worth of XRP, the system will reject the request.

7. Historical fee algorithm (reference)

Perpetual contract maker fee: 0.02 % ~ 0.015 %; taker fee: 0.05 % ~ 0.03 %.
Funding fee is charged every 12 hours (10:00 UTC and 22:00 UTC) with the formula: Funding fee = contract value × number of contracts × funding rate.

Realised / unrealised P&L formulas for contracts

Realised P&L (long):

\[(contract value ÷ settlement reference price – contract value ÷ average closing price) × quantity closed\]

Realised P&L (short):

\[(contract value ÷ average closing price – contract value ÷ settlement reference price) × quantity closed\]

Unrealised P&L (long):

\[(contract value ÷ settlement reference price – contract value ÷ latest mark price) × position size\]

Unrealised P&L (short):

\[(contract value ÷ latest mark price – contract value ÷ settlement reference price) × position size\]

Line chart of total OKB holdings over time

Total OKB holdings (spot)

Refers to the aggregate amount of OKB held across a user’s main and sub‑accounts in funding, trading, and financial wallets (excluding “Earn”‑type products).

Parent‑child account explanation (spot)

The parent‑account tier is based on the cumulative 30‑day trading volume of all sub‑accounts together with the daily asset snapshot, combined with OKB holdings. A sub‑account inherits the parent’s fee tier after 24:00 (UTC+8) on the day it is created.

30‑day trading volume (spot)

Spot trading volume is also converted to BTC using the USD‑BTC price, then to USD using the daily BTC/USD mid‑price. The system settles at 00:00 (UTC+8) each day.

Asset amount (spot)

At 00:00 (UTC+8) each day the platform snapshots the user’s holdings of each cryptocurrency, converts each to BTC using the USDT price, then to USD via the BTC/USD mid‑price. The higher of the 30‑day average asset amount and the current snapshot is used as the final asset amount.

Maker vs. taker (spot)

Maker: Place an order at a chosen price and wait for a counter‑party to fill it; a maker fee is charged upon execution.
Taker: Execute immediately at market price or a better price; a taker fee is charged.

Fee collection rule (spot / margin)

Fee = fee rate × quantity of the asset bought or sold at the moment of trade.

Example (BTC/USDT)

Maker fee 0.08 %, taker fee 0.10 %. If Alice buys 1 BTC at market price (taker), she pays a fee of 0.001 BTC, receiving 0.999 BTC net.
If Alice sells 1 BTC using a limit order (maker), she pays 16 USDT in fees, receiving 19,984 USDT net.

Negative maker fee rebate: When the maker fee rate is negative (e.g., ‑0.002 %), the system rebates that proportion to the maker side using the same calculation method.

24‑hour withdrawal limit (USD)

Every day at 00:00 (UTC+8) the platform calculates a user’s withdrawal ceiling for the next 24 hours based on the fee tier. All withdrawals, after conversion to USD at the prevailing rate, must stay within this ceiling. The limit is also bound by the user’s verification level.

Fee‑tier update schedule

The platform typically refreshes fee tiers between 04:00 and 06:00 (UTC+8) each day.
