In the United States, wealth‑management firms typically charge a percentage‑of‑assets‑under‑management (AUM) fee. For a $10 million portfolio the most common fee structures are:

• Tiered AUM fees – many firms charge about 1 % on the first $1 M and a lower rate (≈ 0.8 %) on the remaining balance. That works out to roughly $80 k – $90 k per year for a $10 M account.
• Flat‑rate or “large‑account” discounts – some advisers offer a reduced flat fee for high‑net‑worth clients, often 0.5 %–0.75 % of AUM, which translates to $50 k – $75 k annually.
• Alternative pricing – a few boutique firms or private banks may propose a fixed annual retainer (e.g., $30 k–$60 k) plus limited performance bonuses, especially when the client wants broader services such as tax planning, estate advice, and concierge supportexpatwealthatwork.com.

So, a typical U.S. client with a $10 million portfolio can expect to pay roughly $50 k–$100 k per year, depending on the adviser’s fee model, the level of service, and any negotiated discounts.
