# Profit Share & Flat Fee

### **More Fee Options**

Aster has implemented a profit-sharing model to reduce the impact of fees on users. When the position is profitable, a fee range from 15% to 20% will be charged on the profits. When the position incurs a loss, no fees will be incurred.

For example, a 15% fee will be charged on the profits when you place orders on BTCUSDT or ETHUSDT pairs.

In the meantime, users can select the flat fee ratio when opening the position. 0.03% will be charged based on the notional value of the position.&#x20;
