Solution: The calculation methods and legal basis of overdue repayment interest may vary depending on the specific circumstances and applicable laws. Here are some common ways and legal provisions:

1、Interest rate agreement: If there is a clear agreement in the loan contract or credit agreement regarding the interest rate for overdue repayment, the borrower is required to pay the agreed interest rate.

2、Default interest rate: In the absence of a specific agreement, the lender may be entitled to charge a default interest rate. This rate is typically higher than the regular interest rate and is often set by law or industry standards.

3、Usury laws: Some jurisdictions have usury laws that cap the maximum interest rate that can be charged on loans. If the interest rate charged exceeds the legal limit, the borrower may be able to reduce the amount of interest owed.

4、Contractual provisions: The loan contract or credit agreement may include specific provisions regarding overdue repayment, including the calculation of interest and any penalties.

5、Legal requirements: In some cases, the law may impose certain requirements for the calculation of overdue repayment interest. For example, certain consumer protection laws may limit the amount of interest that can be charged.

Suggestion for reference:

1、Read the loan contract carefully: Before entering into a loan agreement, borrowers should carefully read and understand the terms and conditions, including the provisions regarding interest and repayment.

2、Negotiate if possible: If the borrower is facing financial difficulties and unable to meet the repayment schedule, they may consider negotiating with the lender to modify the terms of the loan, including the interest rate or repayment plan.
