Mercer Advisors Review (2026): Fees, Fiduciary Status, and Minimum

Guides › Financial Advisor Fees

Updated September 18, 2026. Quick answer: Mercer Advisors is a registered investment adviser. Per its own current fee brochure, a $500,000 account would run $15,000 a year under its published fee schedule; the minimum to open an account is no published minimum account size, but a $15,000-a-year minimum fee for Custom Wealth. Already a client and thinking about leaving? Budget $0 from Mercer itself; custodian-dependent. Is it a fiduciary? Yes, as a registered investment adviser, on the advisory services this page covers.

What Mercer Advisors’ own fee schedule charges

“WEALTH MANAGEMENT TIERED ADVISORY FEES, PERCENTAGE OF ASSETS MANAGED: First $1,000,000, 1.10%; Next $1,000,000, 1.00%; Next $3,000,000, 0.90%; Next $5,000,000, 0.75%; Over $10,000,000, 0.50%. Minimum Fee, $15,000.”

Mercer’s Custom Wealth tier carries a $15,000 annual minimum fee. The raw percentage math at $250,000, $500,000 and $1,000,000 (roughly $2,750 to $11,000) is overridden by that floor, so the actual billed fee at each of those balances is the flat $15,000 minimum; the percentage schedule only governs once assets are large enough to exceed it, which happens above roughly $1,360,000.

Account balanceAnnual fee
$250,000$15,000
$500,000$15,000
$1,000,000$15,000
$2,000,000$21,000

What it costs to leave

Mercer Advisors’ own Form ADV prorates fees to the termination date with any prepaid balance refunded and charges nothing itself to leave; what you pay to move the assets depends on your custodian (Schwab, Fidelity, Raymond James, or National Financial Services).

Methodology. This page was built September 18, 2026, drawing directly on Mercer 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 Mercer Advisors’ own Form ADV Part 2A and Form CRS. We have not used Mercer Advisors as a client. Mercer Advisors did not pay for, review, or influence this content. See our Editorial Policy, Corrections, Affiliate Disclosure, and Disclaimer.
