I think the take away message is always 'what type of life do you want to have".
A million dollars for what I want to do in my retirement is the bare minimum, so for me your husbands is not "absurd" at all. and believe me, that is for me to maintain how I live now, not living la vida loca.
I'm the opposite, I never believed my expenses would go down in my retirement. First of all I want to have two places to live, so right there is another expense. I love big city living (Philly) a condo in Old city Philly is crazy expensive but it's where I want to be during the spring, summer & fall, and then "fly" to some where warm during the winter months right now it's either florida or St. Thomas USVI.
Next I absolutely want to travel the world.
I plan on seeing every continent except for antartica.
I won't get into the pro/against financial advisors argument except to say, I have one, I think he does an excellent job for me. I'm not doing it myself, have no desire to do it myself and he's consistently made me money so I'm a happy camper. Yes I pay him a fee to do so, I also pay my plumber, electrician and lawnscapping guys. LOL I plan on dying without ever mowing my own grass or doing my own taxes.
Works for me.
That's always my big take home message. find what works for you and go for it.
use the tools available and tailor the information to your particular circumstance.
