BA II Professional

A list of helpful tips & tricks:

• Increasing/Decreasing Annuity - This method is a bit of a hack and you still need to divide through by the interest rate.

• Compound Growth Annuity - Much like calculating a normal Annuity but with a clever trick at t=60s.

• Bond Spreadsheet - An example of calculating bond price PRI and accrued interest AI on a bond. Interest is accrued when the bond is sold between coupon payments. The BA II Plus uses the Semi-Theoretical Method.

• Format Settings - Switch between Chain (CHN: operators are applied immediately with no precedence) and Algebraic Operating System (AOS: the expression is evaluated using PEMDAS).

• Calculating the modified duration of an annuity immediate.

What is the modified duration of a 4 year annuity with level payments of $500 and a 6% annual yield?
