reasonable. Microfinance actually belongs to the category of private lending. According to the regulations, the interest rate of microfinance does not exceed four times the interest rate of financial institutions at the same period and the same grade announced by the People's Bank of China, so this interest range is legal. Therefore, everyone can calculate the interest of small loans. If it does not exceed this standard, the borrower must pay the interest as agreed. As long as it exceeds this standard, the interest on microfinance is illegal, and the borrower can not pay the excess interest. If you encounter a small loan with illegal interest, you can negotiate with the lending institution to return only the interest within the legal scope. If the negotiation fails, you can report or complain directly to the relevant departments.
