# Burn To manage their collateralization ratio, users might want to burn ***zUSD*** to reduce their outstanding debt and improve their collateralization ratio or allow them to withdraw collateral. To burn ***zUSD*** a user needs to navigate to the ***Repay*** tab on the ***Mint*** page. The user can then input the amount of ***zUSD*** they wish to burn. This will decrease a users outstanding debt, thus increasing their collateralization ratio. If a user wishes to burn ***zUSD*** without withdrawing any collateral, they have to keep the input box for collateral to withdraw at 0.0. --- # 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.
