# Repaying $USC

To withdraw your collateral, you must first repay borrowed $USC. When $USC debt is repaid, these $USC tokens are burnt (removed from circulation). *For steps on how to repay $USC, please click* [*here*](https://doc.orby.network/user-guide/how-to-repay-usdusc)*.*

Here's what you need to know about the repayment process: 

1. A **minimum of 100 $USC** must remain in a shuttle to keep it active.
2. If you repay your entire debt, your shuttle will be **closed** (become inactive).
3. **Liquidation Reserve Policy:** If your shuttle is closed, the **20 $USC liquidation reserve** is **not refundable**—it will be burnt and permanently removed from circulation.

#### Important Note

You **do not** need to repay the **20 $USC liquidation reserve** unless you are **liquidated**. This reserve is only deducted in the event of liquidation and is not part of your repayable debt.

## Commonly asked questions

<details>

<summary>My shuttle says I owe [$120.50], but I only need to repay [$100.50]. Why?</summary>

That's because you don't have to repay the USC20 liquidation reserve. This reserve is ONLY charged to you if you get liquidated.&#x20;

<summary>My debt is [$120.50]. Why can I only partially pay a maximum of [$0.50]?</summary>

You can either choose to 1) fully repay or 2) partially repay your debt. If you partially repay your debt, keep in mind you need to maintain at least USC100 in your shuttle at all times.&#x20;

For example, if you have borrowed $120.50 USC, this is how much you need to repay:

* Full repayment = shuttle debt amount - liquidation reserve = 120.50 USC - 20 USC = 100.50 USC
* Max partial repayment = shuttle debt amount - liquidation reserve - minimum USC 100 in a shuttle = 120.50 USC - 20 USC - 100 USC = 0.50 USC&#x20;
