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); SoFi Invest discloses a flat, non-negotiable rate of 0.25% (Form ADV Part 2A – SoFi Wealth LLC Brochure, 2026-03-27).

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.

SoFi Invest (Form ADV Part 2A – SoFi Wealth LLC Brochure, 2026-03-27): “Clients are charged an annual asset-based fee (the “wrap fee”) at the rate of 0.25% based on the value of each account enrolled in the program. This fee is non-negotiable.”

Flat, non-negotiable 0.25% annual wrap fee applied to the full account balance at any AUM level (SoFi Wealth’s automated/robo investing service, branded SoFi Invest, has no stated minimum or tiering in the fee schedule itself). Dollar figures = balance x 0.0025.
