Tax-Free Individual Retirement (IRA) of Keogh
Plan.
The advent of tax-free retirement accounts (IRA or Keogh) has resulted in
considerable benefits for many person who are not able to participate in
group profit sharing or retirement plans. The savings due to tax-free status
are often considerable, but complex to calculate. Required data are: the
years to retirement, the total annual investment, the compound annual
interest rate of the investment, and an assumed tax rate which would be
paid on a similar non taxfree investment. This program calculates:
1. The future cash value of the tax-free investment.
2. The total cash paid in.
3. The total dividends paid.
4. The future value of the investment at retirement, assuming that after
retirement you withdrew the money at a rate which causes the money to
be taxed at 1/2 the rate at which it would otherwise have been taxed during
the pay in period.
5. The diminished purchasing power assuming a given annual inflation rate.
6. The future value of a comparable taxable investment.
7. The diminished purchasing power of a comparable taxable investment.
Notes:
The calculations run from the beginning of the first year to the end of the
last year.
The interest (annual yield), i, should be entered to as many significant fig-
ures as possible for maximum accuracy.
The assumed 10% annual inflation rate may be changed by modifying the
program at lines 19 and 20.
The assumed tax rate used to calculate the after tax value of the tax-free
investment may be changed by modifying the program at line 9.
