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.
For example, Fidelity and Charles Schwab offer IRA accounts with no maintenance fees, as does Merrill Lynch and Bank of America. Roth IRAs with no annual maintenance fees are pretty common. For those companies that do charge a fee, typical Roth IRA custodial fees range from $10 to $50 per year.Many financial institutions that do charge an annual IRA maintenance fee offer to waive that charge if certain conditions are met.hat means that annual maintenance fees on Roth IRAs can add up to big money. Someone who starts an IRA at age 20 and pays a $30 annual maintenance fee will have paid almost $1,200 in fees by the time they can withdraw the money without penalty at age 59 1/2.
