How to choose between them

1. Decide how you want to pay. Hourly and flat-fee planners suit people who want a plan and will implement it themselves. A percentage-of-assets fee buys ongoing investment management; on $1 million at 1% that is $10,000 a year, every year.
2. Check the SEC record. Each listing links to the firm’s page on the SEC’s Investment Adviser Public Disclosure site, where you can read the Form ADV Part 2 brochure (fees, minimums, conflicts) and any disciplinary history.
3. Ask who you will actually work with and what credentials they hold. The advisor versus consultant guide explains which titles are regulated and which are marketing.
4. Ask about minimums. Form ADV Part 1 does not record account minimums, so they are not shown here. Many asset-based firms require $500,000 or more; hourly planners usually have none.
5. Get the fee in writing before you sign, including fund expenses and any platform or custody charges on top.

Frequently asked questions

What does fee-only mean?

A fee-only adviser is paid only by its clients, through hourly charges, flat fees, subscriptions or a percentage of the assets it manages. It does not earn commissions on products it recommends. In this directory the label is applied from each firm’s own Form ADV: the firm reports no commission compensation, is not a broker-dealer or registered representative of one, does not act as an insurance agent, and reports no related broker-dealer or insurance agency.

How much does a fee-only financial adviser cost in San Mateo?

Form ADV records how firms charge, not what they charge. Of the 20 firms listed here, 15 offer hourly or flat fees and 16 charge a percentage of assets. Each firm’s Form ADV Part 2 brochure, linked from its profile, gives its actual fee schedule. Nationally, asset-based fees commonly run around 1% a year on the first $1 million and fall above that.

How were these San Mateo advisers selected?

Every registered investment adviser with an office in San Mateo that serves individuals, offers financial planning or portfolio management, and reports no commission or insurance compensation on its Form ADV is listed. Inclusion is free and automatic; no firm pays to appear. The methodology page has the full rules.

Are these advisers fiduciaries?

Registered investment advisers owe their clients a fiduciary duty under the Investment Advisers Act of 1940 for the advice they give. Ask any firm to confirm in writing that it acts as a fiduciary at all times and for all of your accounts.
