What you are thinking about is something called "Perpetual Annuity". You can get it as follows:

$50,000 / 7% =$714,285.71. This is how much you must save in 35 years from age 25 to 60. So, the question becomes how much must you deposit each month OR each year to get the above amount at age 6o?.

 

This is the formula you will use to attain your goal. Will assume annual deposits.

FV =P x {[1 + R]^N - 1 / R}

$714,285.71 =P x {[1 + 0.07]^35 - 1 / 0.07}, solve for P, or annual payment.

P =$5,167.11 - This is what you must deposit each year in your fund to get $714,285.71 at 60, which will allow you to withdraw $50,000 @ 7% FOREVER !!.

P.S. Try and do the math in the above formula and let us see if you can get the same answer that I did.
