Principal Securities Review (2026): Fees, Fiduciary Status, and Minimum

Guides › Financial Advisor Fees

Updated September 24, 2026. Quick answer: Principal Securities is registered with the SEC as both a broker-dealer and an investment adviser. Per its own current fee brochure, a $500,000 account would run $8,750 a year under its published fee schedule; the minimum to open an account is no fixed published minimum for SEI Investment Management Corporation Client Fee Schedule (TPMM Program, Managed Account Solutions). Is it a fiduciary? Yes, when it is acting as your investment adviser; when the same representative acts as your broker-dealer instead, the applicable standard is best-interest, not fiduciary, and its own Form CRS states representatives can earn commissions in that capacity.

What Principal Securities’ own fee schedule charges

“The annual fee Principal Securities charges under an investment adviser arrangement for each TPMM Program is listed below. Principal Securities, through its investment adviser arrangement with SEI, sets its advisory fee as a percent of the asset value of the client’s account at the end of each quarter. The advisory fee Principal Securities collects is negotiable, but will not exceed the following fee schedule (expressed as annualized fees): SEI Investment Management Corporation Client Fee Schedule, Managed Account Solutions – Asset Value / Principal Securities Fee: $0 – $149,999, Up to 1.75%; $150,000 – $249,999, Up to 1.75%; $250,000 – $500,000, Up to 1.75%; $500,001 – $999,999, Up to 1.20%; $1 million and up, Up to 1.10%.”

Treating the published breakpoints as marginal bands (the rate on each band applies only to the dollars within that band, consistent with how Principal Securities’ own wrap-fee brochure describes breakpoint reductions applying only to amounts above a threshold): the first three bands share the same 1.75% rate, so dollars $0 to $500,000 are charged at 1.75%, the next band $500,000 to $1,000,000 at 1.20%, and anything above $1,000,000 at 1.10%. At $250,000, all dollars are in the 1.75% band: 250000 x 0.0175 = 4375. At $500,000: 500000 x 0.0175 = 8750. At $1,000,000: (500000 x 0.0175) + (500000 x 0.0120) = 8750 + 6000 = 14750. At $2,000,000: (500000 x 0.0175) + (500000 x 0.0120) + (1000000 x 0.0110) = 8750 + 6000 + 11000 = 25750.

This page was built September 24, 2026, drawing directly on Principal Securities’ own current fee brochure and Form CRS, both linked above, plus this site’s own already-published fiduciary and minimum-investment pages for the same firm, each independently sourced when it was built. Any distinction we could not independently confirm this session is named as an honest gap rather than presented as verified. Nothing here is personalized financial, tax, legal, or investment advice, and it is not a substitute for reading Principal Securities’ own Form ADV Part 2A and Form CRS.
