# Fees

AstherusEX charges a maker fee of 0.02% and a taker fee of 0.07%.

**How are fees calculated?**

Transaction fee = Nominal value × Transaction fee rate

whereby:

* *Nominal value = Number of futures contracts × Transaction price*<br>

For example, you place a market order for BTCUSDT at market price of $60k USD:

Nominal value = Number of futures contracts × Transaction price\
\= 0.1 BTC × 60,000\
\= 6,000

As a Taker, you would pay a transaction fee of 6,000 × 0.07% = 4.2 USDT.

If BTCUSDT price increases, you could place a Maker sell order.&#x20;

As a Maker, you would pay a transaction fee of 6,000 × 0.02% = 1.2 USDT.

**Glossary**

Maker Order: A maker order is not filled immediately. It goes to the order book and stays there until another trader fills the order.

Taker Order: A taker order is filled immediately as you are filling an existing order with a matching price on the order book. <br>
