1. The present value of interest payable in each period refers to the sum of the present value of interest payable in each period of bonds, which can be calculated according to the following formula: the present value of interest payable in each period = the amount of interest payable in each period /( 1+ present value interest rate) the number of periods, where the amount of interest payable in each period refers to the amount of interest payable in each period of bonds, the present value interest rate refers to the current market interest rate, and the number of periods refers to the number of repayment periods of bonds.
2. The present value of maturity principal and interest refers to the present value of the principal payable and the interest in the last period when the bond matures, which can be calculated by the following formula: the present value of maturity principal and interest = (face value+interest in the last period) /( 1+ current interest rate) the number of maturity periods, where the face value refers to the face value of the bond, the number of maturity periods refers to the number of maturity periods, and the interest in the last period refers to the amount of interest payable in the bond.
