Roughly $28K in several accounts. I'm 27, contributing 15%+4% to the 401K, plus maxing my Roth IRA every year. Got a late start relative to my age due to dragging my ass through college. Given the ol' 8% standard return, I should have plenty to retire on even if I never get another raise in my life. *Knock on wood* I also have roughly that much in non-sheltered investments. I make a modest salary but try to live very frugally with the exception of my cars and where I live.
I've been trying to advise my coworkers against screwing themselves in the ass, but they are all running from their 401ks and STOPPING contributions because the market fell. I tell them to buy low so they can sell high, but emotions run deep.
