How to choose a company for an IRA?
I use TIAA-Cref for my 403(b) and Fidelity for my solo 401(k) and IRAs.  I have previously used Vanguard and have also used other discount brokers for my IRA. All of these companies will charge you nothing for an IRA, so there's really no point in comparing cost in that respect.  They are all the "cheapest" in this respect. Each one will allow you to purchase their mutual funds and those of their partners for free.  They will charge you some kind of fee to invest in mutual funds of their competitors (like $35 or something).  So the real question is this: which of these institutions offers the best mutual and index funds.  While they are not the worst out there, you will find that TIAA-Cref are dominated by both Vanguard and Fidelity.  The latter two offer far more and larger funds and their funds will always have lower expense ratios than their TIAA-Cref equivalent.  If I could take my money out of TIAA-Cref and put it in Fidelity, I'd do so right now. BTW, you may or may not want to buy individual stocks or ETFs in your account.  Vanguard will let you trade their ETFs for free, and they have lots.  For other ETFs and stocks you will pay $7 or so (depends on your account size).  Fidelity will give you free trades in the many iShares ETFs and charge you $5 for other trades.  TIAA-Cref will not give you any free ETFs and will charge you $8 per trade. Each of these will give you investment advice for free, but that's about what it's worth as well.  The quality of the advice will depend on who picks up the phone, not which institution you use.  I would not make a decision based on this.
