# Trading Fee
Currently, the Perpetuals trading fee structure on Koo.xyz is as follows:
* Taker fee rate: 0.015%
* Maker fee rate: -0.005%
#### **What Do "Maker" and "Taker" Mean?**
**Taker**
When you place an order that trades immediately before going on the order book, either filling partially or fully, those trades will be "taker" trades.
Trades from market orders are always Takers, as market orders can never go on the order book. These trades are "taking" volume off of the order book, and therefore called the "taker."
**Maker**
When you place an order that goes on the order book partially or fully, such as a limit order, any subsequent trades coming from that order will be as a “maker.”
These orders add volume to the order book, helping to "make the market," and are therefore termed the "maker" for any subsequent trades.
**Heads up:** A limit order may not always qualify for Maker fees. If your limit price is **better than** the market price, it will execute as a Taker.
