TimeValue - Investing for Future Income (PDF)

Timevalue shows you how much money you will need to invest now so that you can get the future amount that you want. Through the instructions provided in the manual, you will be able to accurately tell both future and present amount of money, how many years that you want wait until you pull it from earning and even the rate of return that you want the investment to earn. This will work great with both portfolios and insurance accounts, such as annuities (fixed and indexed) and indexed universal life insurance.

As a bonus, the manual also has a formula called perpetuity income. This income and rate combination will tell you how much money you will need and at what interest rate to have a desired fixed amount of income per month for life. Read carefully, do the formulas and see what you come up with.
