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.
Even at financial firms that charge annual custodial fees on their IRA accounts, there are usually ways to get the IRA account for free. Most firms waive all account maintenance fees if customers hold a minimum amount of assets with the company. Typically, this minimum is across all accounts for the whole household.
