I'm 23. Right now I put 10% into my companies 401k and they give me an additional 4% in matching. I haven't started a separate savings plan but will probably start that up in about a year or so.
I live alone, pay around $750/mo for rent, tack on $250 for utilities/bills. On top of that there's school loans & a new motorcycle loan. On my old MC loan I was trying to pay it off as quickly as possible so I was dumping in $500+/mo into that and that can now go into a savings account of some kind.
I'm still in that spending phase since I'm a new grad and can finally get some toys of my own. I won't stop moving for another 6-7 years, most likely once a year, so there's no reason in buying a piece of property at a job location. I might be interested in buying something back in my college town for future purposes but that'll be another year or so.
EDIT: I have NO credit card debt. I only have 1 real card (USAA Visa) and 1 store card (Best Buy that I got to help pay for my Pioneer plasma) and both balances are kept at $0.00, the Best Buy card permanently. I use the USAA credit card only when needed and pay it off immediately. It serves as an emergency source of funding.
