What Is an Annual Asset-Based Fee? What High-Income Families Actually Pay

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

An annual asset-based fee is what an investment adviser charges each year as a percentage of the assets they manage for you, for example 1% of a $3 million portfolio, or $30,000 a year. The fee is usually billed quarterly and taken straight out of your accounts, so it rises when markets rise and falls when they fall. The rate matters less than three details most families never check: which assets count, whether the schedule is tiered or a breakpoint, and what else you pay underneath it.

For a two-income household in the Bay Area or Seattle earning $750,000 to $3 million, with RSUs vesting every quarter and a brokerage account that keeps growing, an asset-based fee quietly becomes one of the largest recurring bills the family pays. It never shows up as an invoice. This guide explains how the fee works, runs the numbers on three common fee schedules, and gives you the four checks to make before you sign.

How an annual asset-based fee is calculated and billed

The adviser applies a percentage to the value of the accounts in the agreement, usually measured at the end (or the average) of each quarter, and bills one quarter of the annual rate each time. A 1% annual fee on a $3,000,000 account is billed at about 0.25% per quarter, or roughly $7,500, and the custodian deducts it from the account.

Registered advisers must spell all of this out in Part 2A of Form ADV, the plain-English brochure every adviser gives you. Item 5 requires the adviser to provide the fee schedule, say whether fees are negotiable, say whether fees are deducted from your assets or billed to you, explain how often, list other fees you may pay (such as fund expenses and custody costs), and explain refunds of fees paid in advance (SEC Form ADV Part 2 instructions). You can pull any adviser’s brochure for free on the SEC’s Investment Adviser Public Disclosure site. If you read only one section of that document, read Item 5.

Flat, tiered and breakpoint schedules are not the same fee

Three families quoted “about 0.8%” can pay very different amounts, because the schedule shape changes the math.

• Flat percentage. One rate on every dollar. Simple, and it never gets cheaper as the account grows.
• Tiered (marginal). Each band of assets has its own rate, like tax brackets. For example 1.00% on the first $1 million, 0.75% on the next $2 million, 0.50% above $3 million. Only the dollars inside a band pay that band’s rate.
• Breakpoint (whole-account). Once the account crosses a threshold, the lower rate applies to the entire balance. This is cheaper than tiered at the same stated rates, and the two are often confused in conversation.

Some firms skip percentages and charge a flat annual retainer or a planning fee. A flat fee does not grow with the portfolio, which matters a great deal for a family whose assets are compounding and receiving new RSU shares every quarter.

Worked example: a $1.1 million household with $3 million invested

Assumptions, all hypothetical and chosen for illustration: a married couple in San Mateo County, both W-2 (one at a biotech company, one a physician), $1.1 million combined income, two children ages 4 and 8. They have $3,000,000 to hand to an adviser: $2,200,000 in a taxable brokerage account built from sold RSUs and $800,000 across two 401(k) rollovers. The portfolio earns 6% a year before fees. Fees are charged once a year on the year-end value, with no new money, no withdrawals and no taxes, so the only difference between the rows is the fee.

Three things stand out. First, the 1% family ends about $1,752,000 behind the no-fee reference, but paid only $1,044,854 in fees. The other roughly $707,000 is growth that the fee dollars would have earned if they had stayed invested. The SEC makes the same point in its investor bulletin on fees: as the portfolio grows, so does the total amount of fees you pay, and money paid in fees stops earning a return (SEC Investor Bulletin: How Fees and Expenses Affect Your Investment Portfolio).

Second, the gap between the 1% schedule and the flat retainer is $818,000 at year 20, for what could be the same service. Third, none of this includes fund expense ratios, which are charged inside the funds on top of the advisory fee. A portfolio of low-cost index funds and one of actively managed funds can differ by several tenths of a percent a year, and that difference compounds the same way.

The point is not that 1% is always wrong. An adviser who handles RSU diversification, tax-loss harvesting across a large taxable account, estate documents and the children’s accounts may be worth more than one who only rebalances. The point is to know the dollar figure and what it buys.

Why the fee hits harder in California and Washington

An asset-based fee deducted from a taxable account often forces a small sale each quarter. In California, any gain on that sale is taxed as ordinary income, because California does not have a lower rate for capital gains. At this family’s income, that stacks on top of the federal 3.8% Net Investment Income Tax, which for 2026 applies to married couples filing jointly with modified AGI over $250,000 (IRS).

In Washington there is no wage income tax in 2026, but the state taxes long-term capital gains at 7%, rising to 9.9% on taxable gains above $1,000,000, once gains exceed the annual standard deduction ($278,000 for 2025, the latest published figure) (WA Department of Revenue). Washington has also enacted a 9.9% income tax on AGI over $1,000,000 starting January 1, 2028 (WA DOR), so high-earning Seattle families should not plan on the no-income-tax status lasting.

On the federal side, advisory fees are not deductible. IRS Publication 529 states that you can no longer claim any miscellaneous itemized deductions subject to the 2%-of-AGI limit, the category investment fees used to fall under (IRS Pub 529). So every dollar of fee is an after-tax dollar.

Four checks before you sign an asset-based fee agreement

1. Ask for the fee in dollars, not percent. Have the adviser write down this year’s expected fee on your actual balance, plus fund expenses in dollars. For our example family that is $30,000 on the starting $3 million at 1% (the table shows $31,800 because it bills on the year-end value), before fund costs. A number with a dollar sign is easier to judge than “one percent”.
2. Confirm exactly which assets are billed. Ask whether the fee applies to cash and money market balances, to RSU shares still sitting at your employer’s stock plan broker, to 401(k) balances they advise on but do not hold, and to 529 plans. A family with a large, concentrated RSU position can see the fee jump when unvested shares vest into the managed account.
3. Check tiered versus breakpoint, and whether it is negotiable. Form ADV Item 5 must disclose whether fees are negotiable. At $3 million and up, ask. Also ask whether household accounts are combined to reach lower tiers.
4. List what is included. Tax planning around RSU vests and ESPP sales, estate plan coordination, guardianship and trust review for minor children, dependent care FSA and mega backdoor Roth decisions during open enrollment. If these cost extra, the asset-based fee is only part of the bill.

Common mistakes high-income families make with advisory fees

• Comparing rates across different schedules. A 0.85% flat fee and a tiered schedule starting at 1% can come out almost even at $3 million. Compare dollars on your balance.
• Ignoring the fund layer. The advisory fee in the agreement is not the total cost. Ask for the weighted expense ratio of the recommended portfolio.
• Letting cash sit in a billed account. An emergency fund or a house down payment parked in the managed account can be billed at the full rate while earning money-market interest.
• Never revisiting the agreement. A schedule that made sense at $1 million may not at $4 million. Review it whenever the portfolio doubles or a large liquidity event (a big RSU refresh, an IPO, a home sale) lands.

What to write down for your children

Children see that the family has an adviser. They rarely see why that adviser was chosen, what the family pays, or what the family expects in return. Write a one-page note: the fee in dollars, what it covers, what you compared it against, and when you plan to review it. When your children are teenagers, that page teaches them more about the cost of advice than any course.

As Kevin Luu puts it: “Your kids don’t need to inherit your portfolio. They need to inherit your decision-making process.” A documented fee decision is a small, concrete piece of that process, and it belongs in your FamilyKnowledge® Library alongside the bigger ones.

Frequently asked questions

What is a typical asset-based fee?

There is no official standard rate, and published surveys disagree, which is why this guide does not quote an average. What matters more for your family is the dollar amount on your balance, whether the schedule is tiered or breakpoint, and what the fee includes. Compare two or three Form ADV brochures side by side rather than relying on an average.

Is an asset-based fee better than a flat fee?

Neither is better in every case. An asset-based fee ties the adviser’s pay to the size of the portfolio, which some families like. A flat fee does not grow as the portfolio compounds, which usually favors families with large and rising balances. In our hypothetical example, the flat retainer left about $818,000 more after 20 years than a flat 1% schedule, assuming identical returns.

Can I deduct advisory fees on my taxes?

Not on your federal return. IRS Publication 529 states that miscellaneous itemized deductions subject to the 2%-of-AGI limit can no longer be claimed, and investment advisory fees fall in that group. State treatment differs, so ask your tax preparer about your California return. This is general education, and the right move depends on your family’s full picture.

Your next step

Pull your current adviser’s Form ADV Part 2A from the SEC site, find Item 5, and write your fee as a dollar figure for this year, including fund expenses. If you want a second set of eyes on that number and on how it fits your RSU, tax and estate picture, the Tax & Wealth Assessment from Age Five Family Office™ is a good place to start.
