I guess my questions are:
Do you know if it will be heavy fees for transferring from one Roth IRA to another like that?
Is it smart to do this transfer?
I will wait until I have over $3000 before I start the process because I know that's the lowest minimum deposit I need at Vanguard.
1) Vanguard IMHO is THE BEST because of their industry leading LOW FEES, which they claim are 82% less than the industry avg!
So, you'll want to take FULL advantage of finding funds with LOW FEES.
When you hit $10k - you can move into the EVEN LOWER FEE funds called ADMIRAL FUNDS (free to transfer to other Vanguard funds).
Some of our ROTH IRA's Admiral fund FEES are as low as .05% & that is as LOW as it gets! Lower the fees = KEEP MORE of your own MONEY. For example, the Total Stock Market (Admiral) Index Fund (VTSAX) is only .05% fees (I believe sometimes called expense ratios). .05% can save you tens of thousands of dollars over the long run.
Even a fund that is 0.18% can save you a lot of money. For example, the industry avg is 1.02% when compared to Vanguard's 0.18% expense ratio. A $10k investment earning a 6% avg over 30 years will save you $12,185 in stupid fees. That same scenario means that $50k over 30 years = $60,926 savings; $100k over 30 years = $121,851 in savings.
2) Vanguard didn't charge any fees to transfer from Franklin Templeton or Investco - our other high fee brokerage (both were robbing us blind in fees that we weren't even aware of - including the sneaky 12b-1 "marketing" fees). We were paying something like 1.20% in fees & didn't even have a clue that we were being fleeced. Also be wary of funds that have a buy in fee. You want to look for funds with "no load" or "purchase" fees. No load = no fee to "buy in" to the fund. Be wary of redemption fees that some charge - typically if you sell in a short time. Vanguard has very few funds with any kind of purchase or redemption fees.
3) Vanguard will be able to tell you if USAA charges a fee (I doubt they would charge you) to move your money to Vanguard. Let Vanguard handle the transfer.
4) No need to wait. Vanguard has several target date funds to choose from that only require $1,000 minimum & once you hit $3k you can do free xfer to a different fund, & also once you get to $10k - don't forget about the Admiral funds (which are typically the same as the $1k to $3k investor funds, just with lower fees).
Since you have about 30 years, you might consider (VTIVX) - the 2045 Target date retirement fund (just to get started). It has a 0.18% fee & only requires a minimum of $1k. YTD = 4.66% & 2003 inception is avg of 8.08%. Not too shabby. It's about 90% stocks & 10% bonds. 59% is in the Total Stock Market Index Fund; 30.9% in the Total International Index Fund; 7.5% in the Total Bond Market II Index Fund; & 2.6% in the Total International Bond Index Fund.
