# YBX Fee

**YieldBox Entry and Exit Fees support the sustainability of the protocol**. The fees enable crucial functions for the project.

Rather than selling the bonds to support protocol, our approach is to support the sustainability and growth of YieldBox through fees. A buy and sell fee benefits greatly from trading volume. Higher trading volume brings in more trader interest which in turn help the sustainability of the protocol.

Selling bonds also cost token holders. It reduces the amount of APY that can be offered and eliminates the ability to offer a stable APY. 

The amount of fees (<mark style="color:blue;">**13% for Entry**</mark> and <mark style="color:red;">**15% for Exit**</mark>) allows YieldBox to provide a stable high yield of <mark style="color:blue;">**1,171,519.7**</mark><mark style="color:blue;">%</mark> annually and BUSD reflection to the **$YBX** holders.
