My previous and current employers both use Fidelity for 401(k). Does it make sense to rollover?
I would always suggest rolling over 401(k) plans to traditional IRAs when possible.  Particularly, assuming there is enough money in them that you can get a fee-free account at somewhere like Fidelity or Vanguard.  This is for a couple of reasons. First off, it opens up your investment choices significantly and can allow you significantly reduced expenses related to the account.  You may be able to find a superior offering from Vanguard or Fidelity to what your employer's 401(k) plan allows; typically they only allow a small selection of funds to choose from.  You also may be able to reduce the overhead fees, as many 401(k) plans charge you an administrative fee for being in the plan separate from the funds' costs. Second, it allows you to condense 401(k)s over time; each time you change employers, you can rollover your 401(k) to your regular IRA and not have to deal with a bunch of different accounts with different passwords and such.  Even if they're all at the same provider, odds are you will have to use separate accounts. Third, it avoids issues if your employer goes out of business.  While 401(k) plans are generally fully funded (particularly for former employers who you don't have match or vesting concerns with), it can be a pain sometimes when the plan is terminated to access your funds - they may be locked for months while the bankruptcy court works things out. Finally, employers sometimes make it expensive for you to stay in - particularly if you do have a very small amount.  Don't assume you're allowed to stay in the former employer's 401(k) plan fee-free; the plan will have specific instructions for what to do if you change employers, and it may include being required to leave the plan - or more often, it could increase the fees associated with the plan if you stay in.  Getting out sometimes will save you significantly, even with a low-cost plan.
