# Fees
## Transaction Fees
The fee for opening and closing positions is currently set at **0.03% for 200x leverageļ¼0.05% for 100x or lower leverage.**
{% hint style="info" %}
Transaction Fee = Transaction Value x **fee rate**
{% endhint %}
## Funding Fees
YFX V4 implements the funding fee mechanism to balance the aggregated long and short positions. The funding fee is settled between traders and fund pools.
{% hint style="warning" %}
The funding fee is not settled every 8 hours, but the previous funding fees will be settled every time a transaction is made.
{% endhint %}
**The funding fees on YFX are calculated in seconds on the blockchain, and the 1-hour estimated funding fee displayed on the trading page is the estimated 1-hour funding fee calculated using the real-time funding fees.**
### The 8 hours funding fee formula:
> **F:** Funding Rate
>
> **P:** Premium Index
>
> **I:** Default Interest
$$
F = P + clamp(I - P, -0.05%, 0.05%)\\
I = 0.01% \\
$$
$$
F = \begin{cases}\\
\begin{aligned}
P + 0.05% ;;; & \text{When } P \le -0.04%\\
0.01% ;;; & \text{When }-0.04% \le P \le 0.06% \\
P - 0.05% ;;; &\text{When }P \gt 0.06%\\
\end{aligned}
\end{cases}
$$
Users can find real-time funding rates in their positions, and they can view the funding profit and loss for a particular trade in their trade history. A positive funding rate means the user earned funding, while a negative funding rate means the user paid funding.
## Execution Fees
There are two steps involved in opening/closing/editing a position: The first step is that the user sends a transaction request to the blockchain, including parameters like margin amount and leverage.
The second step is that **Keepers** observe the blockchain for the request, retrieve the price feed from the oracles, then execute the request. After the second step, the transaction is considered to be completely on-chain.
Therefore, when each transaction request is sent to the blockchain, an additional execution fee is required and paid to the blockchain network.
{% hint style="info" %}
Currently, the execution fee on the Arbitrum blockchain is **0.0001** ETH per time.
Execution fees will be adjusted based on the gas fees for each blockchain over certain time periods.
