Legal analysis: If you go to jail, you will have to pay back the interest generated by your credit card. Being in jail is not a reason not to repay the debt. If you have property, you can ask the case handler to pass it on to your family for help in repaying it. If your property is to be confiscated, you must also repay legal debts. Therefore, even if you go to jail, you need to repay the debt, and the interest accrued during this period also needs to be repaid.

Legal basis: Article 676 of the "People's Republic of China and Civil Code" If the borrower fails to return the loan within the agreed time limit, he shall pay overdue interest in accordance with the agreement or relevant national regulations.

Article 60 of the "Criminal Law of the People's Republic of China" If the legitimate debts borne by criminals before the property was confiscated need to be repaid with the confiscated property, they shall be repaid at the request of the creditor.
