Calculation method of debt interest income: debt interest income = principal * interest rate * annual income of national debt maturity = principal * interest rate. Next, will Jintou Bian Xiao launch 654.38+ten thousand national bonds with one-year interest?

1, electronic national debt

Annual income for three years = principal * interest rate = 10000*4%=4000 yuan.

Five-year income = principal * interest rate = 10000*4.27%=4270 yuan.

It means the annual interest rate of electronic national debt is 4,000 yuan for three years and 4,270 yuan for five years.

2. Voucher bonds

.

Total income of three-year national debt = principal * interest rate * term of national debt =10000 * 4% * 3 =12000 yuan.

Average annual interest rate income = total interest rate/holding period = 12000/3=4000 yuan.

Total income of 5-year treasury bonds = principal * interest rate * maturity of treasury bonds =10000 * 4.27% * 5 = 21350 yuan.

Average annual interest income = total interest/holding period =2 1350/5=4270 yuan.

In this way, voucher-type government bonds and electronic government bonds only have different interest payment methods and the same interest.
