# Trading Fee Rate

When trading derivatives on YUBIT, a transaction fee is charged **only when an order is executed**. Fees are deducted directly from your account balance and do not affect the initial margin required to open a position.

**Trading Fee Rates:**

* **Maker (limit order added to the book):** 0.04%
* **Taker (order matched immediately):** 0.08%

**Fee Calculation Example**

Suppose you open a contract with the following details:

* **Order Value:** 100,000 USDT
* **Leverage:** 10x
* **Margin Used:** 10,000 USDT

⚠️ Note: Fees are calculated based on **order value**, not margin used.

**Taker Fee Calculation (0.08%)**

```
Fee = Position Value × Fee Rate
Fee = 100,000 USDT × 0.0008 = 80 USDT
```

Even though you only invested **10,000 USDT margin** due to leverage, the **fee is based on the full 100,000 USDT position size**.

* ✅ Final Fee: 8**0 USDT**

***

**General Formula**

```
Fee = Order Quantity × Contract Price × Fee Rate
```

This formula applies to both Maker and Taker fees, with the respective rate applied.
