6.5% Guaranteed yield?
In this age with low inflation, a 6.5% yield is very high. The current yield on investment grade industrial bonds is 3.3%
$375/m may seem low, but 14,000 $ isn't a lot either. I am living in Europe and part of my retirement is a quilt of state pensions from various countries where I have worked. Each one seems modest since I have worked 4-5 years in each country, but when I add them up, they contribute nicely. After all, the big picture is the sum of small pictures, so if you optimize each bit, it makes a difference.
Neglecting tax effects, 14k $, compounded over 30 years at 6.5% should give a capital of $ 92.600 in 30 years. If they continue to get a 6.5% yield, the annual yield will be higher than 4500, so the capital will continue to grow. But assuming a 20 year life expectancy, you would pull 90,000 out. They would hold a capital over, but if they really managed to get a 6.5% yield over 50 years, I think they have deserved it.
Have a look at the yield of your IRA. And run the calcs using that yield. If I use 4%, the capital will grow to $ 45,400. And once you start drawing your 4500, after 14 years, the capital will have been consumed, still assuming 4% after you retire.
If you can find a tame retirement/investment advisor, it might be an idea to bounce the question of him/her.
