I have recently become eligible for my employer's 401k plan. For reasons that I will not discuss here, I do not intend to stay at my current employer for longer than another year or so at most, perhaps even shorter. Is the 401k still worth taking advantage of? In case it makes a difference, I am currently 26 years of age.
I'll take a slightly different approach, no questions, however, I'm not a financial guru.
I would always say yes, no matter the length of time you intend to be there.
1) Things change
2) Retirement is part of my game plan, whether I work after retirement is irrelevant to me now (it's something I'll be able to decide), I want to be financially able to retire at a reasonable age.
3) Save now, enjoy later, Generally speaking, the few dollars you put away now is worth a lot more 30 years later.
Retirement saving is more of a mind-set for me.
At your age I'd had a "retirement plan" for 3+ years, I look at it once a year to make sure everything is doing alright, then I forget about it, you never know when you might need a decent chunk of change (even if you're penalized, some situations warrant it), it adds up quick. In my experience, you can almost always deal without the extra cash now. When making a financial decision, I always try to consider the five Ps, "proper planning prevents poor performance".
