AAII Program #2 Bond Yields (BOND) (c) Copyright 1982 by the American Association of Individual Investors This program calculates the yield-to-maturity of bonds with and without taxes. Particularly in the case of bonds with less than 10 years to maturity, it is essential to indicate the years PLUS MONTHS. You will need a bond guide as the newspapers only give the year of maturity. The yield is quite different for a bond if it has six years to maturity than if it has six years and six months. The program also asks for your marginal tax rate on ordinary income and on capital gains. If you are not interested in after-tax yields or are evaluating tax-exempt investments, enter 0 for these figures.
