The Government issues treasury bonds at a discount from par at either
a zero or a fixed coupon rate for periods extending beyond one year.
It makes fixed interest payments to the investor semi-annually. At
maturity, the investor receives the face value amount.
This calculator works out the total interest return to an investor
after deducting withholding tax at the standard 15% rate. The National
Treasury from time to time issues tax-exempt infrastructure bonds and
long term bonds at preferential taxation rates.
The calculator allows for a change in the withholding tax rate.
