More about investment

Amount Owed at end of 20 years = $818326.87 - $818326.51
Amount Owed at end of 20 years = $0
Amount Paid at end of 20 years = $50,000 - $0
Amount

Using the rubric:

Sen.

You are assuredly correct. I wonder how many congressmen have diversified portfolio's, and why they don't figure out a way to wean us off the Social Security to a system of required private accounts. I'd bet most have mutual funds where they see 8-12%
