<prompt> Human: The additional details are:- Ive moved to a new company- I have enough money in my old 401k with Fidelity to roll it over into a Roth IRA- However, I want to open the Roth IRA account with Vanguard Is this a good idea? Will I lose out on money? I dont have enough money saved to open the Roth IRA without the 401k rollover.  <response>: traditional 401k should be rolled into a traditional IRA. Roth 401k should be rolled into a Roth IRA.If you follow these rules, you will not lose any money or be taxed on anything. The only reason you would want to cross over from traditional 401k to Roth IRA is if its a very conscious decision on your part after researching the tax consequences, because you specifically want to take the tax hit this year.
