# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
