Should I contribute to my 401K?

All of the money ended up in the accounts eventually, but holding contributions to earn interest from the float was one of the issues. The primary issue was that the fees on lower paid employee 401k accounts were higher than appropriate, while fees on the deferred compensation plan, available only to higher paid employees who had restrictions on their retirement savings due to IRS limitations, were much lower, so that hourly employees were subsidizing the low fees enjoyed by management. Those deferred compensation accounts were only available to people who had compensation exceeding $245,000 in the previous calendar year.

Lots of decent advice already, I’m just going to second:

If your employer matches 401(k) contributions, do (almost) whatever it takes to get this match. Assuming you have at least a halfway decent fund to invest said 401(k) money in, 401(k) + employer match is the best return you will ever see short of a lottery-ticket homerun stock. And you shouldn’t be betting on a homerun stock anyways unless you have plenty of money to risk and burn.

Jumping on the bandwagon of saying “contribute at least enough to get the matching contributions”.

Bear in mind, you won’t be vested in those contributions until you’ve been there a while - some companies are faster than required, but in general, you either get it all once you’ve been there 5 years, or you’re vested in 20% (or more) a year starting at 3 years (or sooner), and fully vested at 7 years. The legally-permissible times used to be a lot longer - e.g. 10 years.

If your employer offers a Roth 401(k) option, it can be a very good idea to put money in that versus the traditional pretax version. Same benefits as a Roth IRA - but without income limitations.
