Value of a Taxable Retirement Account

See appendix F for RPN keystrokes for this example .
This problem uses the TVM menu to calculate the future value of a
taxable retirement account that receives regular, annual payments
beginning today (Begin mode). The annual tax on the interest is paid out
of the account. (Assume the deposits have been taxed already.)
N = the number of years until retirement.
I%YR = the annual interest rate diminished by the tax rate:
interest rate × (1－ tax rate ).
PV = the current amount in the retirement account.
PMT = the amount of the annual payment.
FV = the future value of the retirement account.
Example: Taxable Retirement Account. If you invest $3,000 each year
for 35 years, with dividends taxed as ordinary income, how much will
you have in the account at retirement? Assume an annual dividend rate
of 8.175% and a tax rate of 28%, and that payments begin today.
What will be the purchasing power of that amount in today's dollars,
assuming 8% annual inflation?
