It is illegal to exceed four times the interest rate of bank loans during the same period. It is illegal for online loans and private loans to earn an annual interest of more than 36%. Private lending is a civil act, and the interest rate agreed by the borrower and the lender shall not exceed 24% of the annual interest rate, and the lender has the right to require the borrower to pay interest at the agreed interest rate; However, if the interest rate agreed between the borrower and the borrower exceeds the annual interest rate of 36%, the interest exceeding the annual interest rate of 36% shall be deemed invalid. According to the current domestic practice, the loan interest rate reaches 36% annually, which is generally not illegal, but the law does not guarantee this part of interest income. At present, the domestic loan interest rate has two levels, one is 24%, and the other is 36% annualized. Generally speaking, banks, licensed consumer finance companies and other regular troops, most of their loan interest rates are within 24%; At the same time, the loan interest rate of online lending companies is mostly higher than this level, within 36%. According to the judicial interpretation, if the borrower fails to pay back the money at maturity and both parties go to court, the law will support the lender's appeal and require the borrower to return all the principal and interest to the lender; At the same time, if it is between 24% and 36%, the principal can be repaid in full, but I remember that the interest is levied in half. I'm too lazy to check the details. Anyway, I don't want full interest any more. If it exceeds 36%, the principal will be repaid in full and the interest cannot be recovered. From this perspective, 36% is a legal red line. Once the loan interest rate exceeds this level, it may be suspected of breaking the law, because if it exceeds this interest rate, the interest rate will no longer be guaranteed, and it can also be interpreted as if it exceeds this interest rate, it will be suspected of usury.

Legal basis: Provisions of the Supreme People's Court on Several Issues Concerning the Application of Laws in the Trial of Private Lending Cases Article 26 If the interest rate agreed by both borrowers and lenders does not exceed 24% per annum, the people's court shall support it. The interest rate agreed between the borrower and the borrower exceeds the annual interest rate of 36%, and the interest agreement in excess is invalid. The people's court shall support the borrower's request to the lender to return the interest paid in excess of 36% of the annual interest rate.
