What Mariner Wealth Advisors’ own fee schedule charges

“The structure and level of our advisory fee will vary by client based upon the services provided and other considerations deemed relevant by us, but typically takes the form of a percentage of assets under management and/or advisement, ranging up to 2.50% per annum. … All fee arrangements are subject to negotiation.”

Mariner does not publish a dollar-breakpoint fee table; its Form ADV states a single ceiling of ‘ranging up to 2.50% per annum,’ individually negotiated per client. The dollar figures apply the disclosed 2.50% ceiling as a flat rate to each balance (balance x 0.025); an actual negotiated rate is very likely lower, especially at higher balances. Note on currency: this is the combined CRS/ADV Part 2A/Privacy document currently live at Mariner’s own published URL; its internal revision date, stated on the cover page, is March 30, 2023 – no more recent public version of Mariner, LLC’s firm-level Part 2A brochure (as opposed to smaller affiliated entities like Mariner Institutional or Mariner Platform Solutions) could be located.

Methodology. This page was built September 19, 2026, drawing directly on Mariner Wealth Advisors’ own current fee brochure and Form CRS, both linked above, plus this site’s own already-published fiduciary, minimum-investment, and (where one exists) how-to-leave 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 Mariner Wealth Advisors’ own Form ADV Part 2A and Form CRS. We have not used Mariner Wealth Advisors as a client. Mariner Wealth Advisors did not pay for, review, or influence this content.
