A custodial fee is simply a flat fee charged by a bank or brokerage for administering or managing an IRA. Virtually every type of IRA is associated with some type of custodial fee, regardless of whether you choose a certificate of deposit, a mutual fund or some other type of IRA.
Numerous brokerages, mutual funds, banks, and investment firms offer free IRA accounts without charging an annual IRA fee, and it's not just deep discount brokers either. The average annual IRA account maintenance fee is between $25 and $50 per year from the companies that still charge them. However, paying anything over zero is just plain foolish. Brokerages like Fidelity and Schwab offer free IRA accounts to all of their customers.
