What each firm charges, side by side

Account balanceNorthwestern Mutual (annual fee)SoFi Invest (annual fee)
$250,000$4,125$625
$500,000$8,250$1,250
$1,000,000$16,500$2,500

Northwestern Mutual discloses a maximum, individually negotiated rate of 1.65% (Northwestern Mutual Wealth Management Company Private Client Services Disclosure Brochure, September 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

Northwestern Mutual (Northwestern Mutual Wealth Management Company Private Client Services Disclosure Brochure, September 2026): “NMWMC generally charges an annual Net Advisory Fee of no more than 1.65% on assets in a Private Client Services account. The corresponding annual Gross Advisory Fee is no more than 1.76% before the application of the 0.11% fee offset for proprietary investment management fees discussed below.”

Northwestern Mutual does not publish a public dollar-breakpoint schedule; the tiers on your account are negotiated with your advisor and recorded in a private Statement of Investment Selection. The figures above apply the disclosed 1.65% ceiling as a flat rate; your advisor may offer a lower custom schedule.

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.
