First of all, there is no bank loan with such a low interest rate at present, and the interest depends on the repayment method. If the principal and interest are repaid in one lump sum, the interest will be 2700 yuan.

If the principal and interest are equal, the total interest for one year is 1468.53 yuan, and the interest on average capital is 1462.5 yuan.
