# Revenue

In addition to the Borrow APR, borrowers incur a Protocol Fee. This fee is:

* **Charged to Borrowers:** Borrowers are responsible for paying the Protocol Fee on top of the interest rate they agreed to pay lenders (Borrow APR).
* **Settled During Repayments:** The fee is automatically collected at the time of each repayment.
* **Revenue for Clearpool:** These fees contribute to the overall revenue of Clearpool, which helps support the ongoing development and maintenance of the platform.

By implementing a Protocol Fee, Clearpool can ensure the long-term sustainability and growth of the Credit Vaults ecosystem.
