How Much Does Financial Advice Cost? Adviser Fees and Costs for High-Income Families

By Kevin Luu, Co-Founder and Chief Learning Officer. Reviewed on 2026-09-30.

Financial advice is priced in four ways: a percentage of the assets an adviser manages, a flat annual retainer, an hourly rate, or commissions on products sold. For a family with $3 million invested, those models can produce annual costs that differ by more than $20,000, so the pricing model matters more than the headline number. The only reliable way to know what an adviser charges is to read their Form ADV Part 2A, Item 5, and add up every layer of cost in dollars, not percentages.

This guide is written for high-income W-2 families in California and Washington: two earners, RSUs and ESPP shares building up in a brokerage account, young kids, and not much spare time. It walks through the four pricing models, a worked comparison at a $1.1 million household income, how adviser fees are treated for tax in 2026, and four steps to work out the real cost before you sign.

The four ways advisers charge, and what each one pays for

Two labels cause most of the confusion. Fee-only means the adviser is paid only by the family, through one or more of the first three models. Fee-based sounds similar but usually means a fee plus commissions on some products. For a household that will be pitched permanent life insurance and annuities in the same year it hits a $1 million income, that difference is the one to pin down first. If you are not sure what legal duty a given adviser owes you, our guide on how many advisers are fiduciaries explains the two standards.

Worked example: what a $1.1 million household would pay under each model

Assumptions (illustrative, not a quote from any firm): a married couple in the Bay Area, one a biotech scientist and one a physician, $1.1 million of combined W-2 income, children aged 4 and 8. They have $3 million invested: $2.2 million in a taxable brokerage account (mostly sold RSUs and ESPP shares) and $800,000 across two 401(k)s. The fee levels below are hypothetical round numbers chosen to show the math.

The year-one gap looks manageable. The ten-year gap does not. If the portfolio grows 6% a year (a simplifying assumption, before fees and with no new savings), it reaches about $5.37 million by year ten. Under Proposal A the fee grows with it, and the ten years of fees add up to roughly $395,000. Under Proposal C, even if the retainer rises 3% every year, ten years cost roughly $206,000. That is close to $190,000 of difference before counting the growth the fees themselves would have earned.

Proposal D is cheapest on paper, but it only works if one parent has the time to execute: rebalancing, tax-loss harvesting, deciding what to do at each RSU vest, keeping beneficiary designations current. Most families at this income tell us that time is exactly what they do not have. The honest comparison is not “cheapest fee” but “which model pays for the work we will not do ourselves”.

A percentage fee is not always the wrong answer. If an adviser actively manages a complex portfolio and the fee is capped or tiered down, it can be reasonable. The point is to see it as a dollar figure that compounds, and to ask what additional work the extra dollars buy. For a wider look at how pricing changes as assets grow, see how much a wealth manager costs.

The costs that sit underneath the adviser’s fee

The quoted fee is rarely the full cost. Form ADV Part 2A, Item 5, requires a registered adviser to describe how it is paid, give its fee schedule, say whether fees are negotiable, and describe other fees you may pay, such as custodian fees or mutual fund expenses (SEC Form ADV Part 2 instructions). When you compare proposals, list these layers separately:

• Fund expense ratios. The funds inside the portfolio charge their own annual expenses. An adviser who uses higher-cost funds adds to your bill even if the advisory fee looks low.
• Wrap and platform fees. Some programs bundle trading, custody and management into one percentage. Ask what the bundle contains and whether you could buy the parts for less.
• Commissions and product revenue. Insurance, annuities and some share classes pay the seller. Ask whether anyone at the firm earns anything from a product they recommend to you.
• Separate charges for tax and estate work. A plan that “coordinates with your CPA” may still leave you paying the CPA and the estate attorney in full.

Are financial advisory fees tax-deductible in 2026?

Federal: no. Investment advisory fees are miscellaneous itemized deductions, and the federal suspension of those deductions was made permanent for tax years beginning after December 31, 2025 (26 U.S.C. §67(h), as amended by Pub. L. 119-21 §70110). Many articles still describe this as a temporary rule ending in 2026. It no longer is.

California: yes in principle, but the benefit is usually small at this income. The Franchise Tax Board’s Schedule CA instructions say that under federal law the deduction for miscellaneous itemized deductions subject to the 2% floor is suspended, and “California law does not conform” (FTB 2025 Schedule CA (540) instructions). Two limits apply. Only the amount above 2% of your federal adjusted gross income counts, and for 2025 California also reduces total itemized deductions once federal AGI exceeds $504,411 for joint filers (same source). These are the 2025 rules; California had not published its 2026 forms when this was reviewed.

In our example, suppose federal AGI is $1,050,000. The first $21,000 of investment and similar expenses (2% of AGI) produces no state deduction. If $22,000 of Proposal A’s fee relates to the taxable account (1% of $2.2 million), only about $1,000 clears the floor. At an 11.3% to 12.3% marginal California rate, that is worth roughly $113 to $123 a year, before the high-income limitation. The tax treatment should not decide which adviser you pick.

Washington: there is no individual income tax in 2026, so there is no state deduction question for wages. Washington has enacted a 9.9% tax on individual and joint AGI over $1 million starting January 1, 2028 (Washington DOR), and how it treats expenses such as adviser fees is still pending DOR guidance.

Four steps to work out what advice will cost your family

1. Write down the work you want done. For most two-earner families with equity comp this includes: an RSU and ESPP selling plan, retirement plan choices (including mega backdoor Roth if the plan allows it), 529 and custodial account decisions for the kids, insurance review, estate documents and guardianship, and coordination with the CPA. A narrow need, such as a one-time plan before a job change, may justify hourly pricing. An ongoing need across all of these usually does not.
2. Get every proposal in dollars for this year and year ten. Ask each adviser to show the annual fee at your current balance and at a projected balance. Percentages hide growth; dollars do not.
3. Read Form ADV Part 2A and Form CRS. Search the firm on the SEC’s Investment Adviser Public Disclosure site, open the brochure, and read Item 5. SEC-registered advisers and brokers that serve retail investors must also provide Form CRS, a short summary of fees, services and conflicts (Investor.gov). Our checklist on vetting a financial adviser covers what else to check.
4. Ask four direct questions. Is the fee negotiable? Is it billed from the account or invoiced? What costs are not included? Does anyone at the firm earn money from a product you might recommend to us?

Common mistakes when comparing adviser costs

• Comparing percentages across different fee bases. 0.8% of $3 million is more than a $20,000 flat fee. Always convert to dollars.
• Ignoring what sits outside the account. RSUs that have not vested, the 401(k), the house and the kids’ 529s may not be “managed”, yet they are where most of the decisions are. A percentage fee on the brokerage account alone may not pay for advice on any of them.
• Treating a free first plan as free advice. If there is no fee, ask how the adviser is paid. The answer is often a product.
• Letting the fee model make decisions for you. Under a percentage fee, ask directly whether the adviser would recommend paying down a mortgage or holding cash for a home purchase, since both reduce their pay.

What to write down for your kids

Children rarely see what their parents pay for advice, or why. A short note in your family records can cover it: who you hired, how they are paid, what you expected them to do, and what would make you change. When your children one day hire their own adviser, that note will teach them more than a portfolio statement. As Kevin Luu puts it: “Your kids don’t need to inherit your portfolio. They need to inherit your decision-making process.” The family governance work we do is built around documenting decisions like this one.

Frequently asked questions

Is a 1% advisory fee too high for a family with $3 million?

It depends on what the fee buys. At $3 million, 1% is $30,000 a year and grows with the portfolio. If that covers only investment management, compare it with a flat or tiered alternative. If it also covers tax planning, equity comp strategy, estate coordination and insurance review, the comparison is closer. Convert every proposal to dollars and list the work each one includes.

What is the difference between fee-only and fee-based?

A fee-only adviser is paid only by the family, through an asset-based fee, a flat retainer or an hourly rate. A fee-based adviser charges a fee and may also earn commissions on products such as insurance or annuities. Both can be legitimate, but commissions create a conflict you should understand before you buy any product the adviser recommends.

Can I pay an adviser by the hour instead of a percentage?

Yes. Hourly and project pricing works well for a defined question, such as a plan before a job change or a one-time review of RSU and ESPP holdings. It works less well when you want someone accountable for ongoing execution, because the family still has to carry out the plan and remember to come back when something changes.

Next step

Pull the Form ADV Part 2A for any adviser you are considering, and turn their fee into a ten-year dollar figure using your own balance.
