Cambridge Investment Research discloses a maximum, individually negotiated rate of 2.25% (Cambridge Investment Research Advisors, Inc. Form ADV Part 2A Disclosure Brochure, July 2026); Vanguard Personal Advisor discloses a published gross rate of 0.35% (Vanguard Digital Advisor and Vanguard Personal Advisor Brochure (Form ADV Part 2A), 2026-08-20).

What the fee includes, in each firm’s own words

Cambridge Investment Research (Cambridge Investment Research Advisors, Inc. Form ADV Part 2A Disclosure Brochure, July 2026): “The investment advisory fee for accounts managed through the Cambridge Managed Account Platform (“CMAP”) is based on the amount of assets under management, including cash balances deposited in a Federal Deposit Insured Corporation (“FDIC”) insured multi bank program (“Program”). … The investment advisory fee is negotiable and is subject to discounts on a Financial Professional-by-Financial Professional, client-by-client, or account-by-account basis. … The maximum allowable advisory fee that can be charged will not exceed 2.25% of assets under management on an annual basis.” Maximum annual advisory fee (Cambridge Managed Account Platform, Flexible Managed Account Platform, WealthPort Advisor-directed / Team-directed): 2.25%; Maximum annual advisory fee (WealthPort CAAP / UMA programs): 2.15%.

CIRA’s Form ADV does not publish one fixed rate schedule. Advisory fees on its primary managed-account platforms (CMAP, FlexMAP, WealthPort Advisor-directed/Team-directed) are individually negotiated between the client and Financial Professional, subject to a disclosed maximum of 2.25% of AUM annually (WealthPort CAAP/UMA caps at 2.15%). Because there is no standard published tier table, dollar_at applies the disclosed 2.25% ceiling uniformly across all four balances as the maximum a client could legally be charged under this brochure (250000*0.0225=5625; 500000*0.0225=11250; 1000000*0.0225=22500; 2000000*0.0225=45000). Actual fees are typically lower and individually negotiated per client/advisor.

Vanguard Personal Advisor (Vanguard Digital Advisor and Vanguard Personal Advisor Brochure (Form ADV Part 2A), 2026-08-20): “Personal Advisor’s annual gross advisory fee for Vanguard Brokerage Accounts is 0.35% for its all‐index investment options and 0.40% for the exclusive active/index mix. … Enrollments in Personal Advisor require an aggregate $50,000 balance or greater” All-index investment option (any enrolled balance; $50,000 aggregate minimum to enroll): 0.35%; Active/index mix investment option (any enrolled balance): 0.40%.

Flat (non-tiered) gross advisory fee applied to the entire enrolled Vanguard Brokerage Account balance regardless of balance size: 0.35% for the all-index investment option (used here as the base case) or 0.40% if the active/index mix is elected. Dollar figures = balance x 0.0035. This is Vanguard’s disclosed gross fee before the affiliate-revenue credit that Vanguard also applies (which further lowers the net fee actually charged, per the same brochure); the gross rate is used here because it is the stated contractual rate, not an estimate.
