One cent five interest is .15%.

interest = principal × years (months) × years (months) interest rate

If the interest-bearing period has a whole year (months) and a fraction of days, the interest-bearing formula is:

interest = principal × years (months) × years (months) interest rate+principal × fraction of days × daily interest rate

Repayment method

Edit

(1) Equal repayment of principal and interest: that is, the sum of the principal and interest of the loan adopts a method of equal monthly repayment. Housing provident fund loans and commercial personal housing loans of most banks have adopted this method. This way, the monthly repayment amount is the same;

(2) repayment of equal principal: that is, a repayment method in which the borrower evenly distributes the loan amount to each installment (month) throughout the repayment period and pays off the loan interest from the previous trading day to the repayment day. In this way, the monthly repayment amount decreases month by month;

(3) Pay interest on a monthly basis and repay the principal at maturity: that is, the borrower will repay the loan principal in one lump sum on the loan maturity date (applicable to loans with a term of less than one year (including one year)), and the loan will bear interest on a daily basis and the interest will be repaid on a monthly basis;

(4) prepayment of part of the loan: the borrower can prepay part of the loan amount, usually 1, yuan or an integer multiple of 1, yuan. After repayment, the loan bank will issue a new repayment plan, in which the repayment amount and repayment period are changed, but the repayment method is unchanged, and the new repayment period shall not exceed the original loan period

(5) prepayment of all the loans: the borrower applies to the bank.

(6) Pay back as you borrow: the interest after borrowing is calculated on a daily basis, and the interest is calculated on a daily basis. You can settle the money in one lump sum at any time without penalty
