Hi, good for you for starting early - Albert Einstein once said the most powerful force in the universe is compounded interest. You can't set up a 403b or a 401k, that would depend on what your company offers. However, you can set up a traditional IRA or Roth IRA. If you'd like more info, check out http://www.plannerconnect.com/retirement-planning- retirement-income-ira.html. You should try to save as much as you can - maybe make a goal of 10% a month?

first does your firm have a matching fund if so that is you best bet == match at least what they put up in other words if they say they will put of 50% up to 10% of your salary you put up the 10%===

if not go with the roth you can only put in up to 4k a year but the earnings are not taxable!!!

then you can think about the ira to save on your income tax

good luck and good savings it is a such a plasure to answer question from some one who is no over their head in debt!!!
