What each firm charges, side by side
| Account balance | Mariner Wealth Advisors (annual fee) | SoFi Invest (annual fee) |

| $500,000 | $12,500 | $1,250 |

Mariner Wealth Advisors discloses a maximum, individually negotiated rate of 2.5% (Mariner, LLC (d/b/a Mariner Wealth Advisors) Form ADV Part 2A Brochure, March 30, 2023); 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
Mariner Wealth Advisors (Mariner, LLC (d/b/a Mariner Wealth Advisors) Form ADV Part 2A Brochure, March 30, 2023): “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.
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.
