Are Wealth Advisors Worth It? What the Data Says at $15M

Wealth Manager or Self-Manage at $15M: What Investors Choose

Most investors at this level manage their own portfolios, and the ones who use an advisor usually hand over only part of it. In Long Angle's 2026 study, 57% of respondents said they do not work with a financial advisor, RIA or wealth manager, and half said they have no interest in using one.

The other 43% split unevenly. Twice as many respondents use an advisor for some assets as for most or all of them, which makes the partial relationship the most common way investors at this level use one.

Respondents are Long Angle members who chose to take part, not a representative sample of high-net-worth households. The study does not break advisor use out by net worth band.

A smaller Long Angle survey points the same way and adds the wealth gradient. In the 2025 High-Net-Worth Professional Services Report, 32% of 114 respondents used a wealth manager. Usage rose with net worth, from 22% of respondents under $5M to 44% of those with $25M or more, so even in the top band most respondents did not use one. That sample is small, and the report gives no figure for the $10M to $25M band where $15M sits, so treat it as support for the larger study rather than a separate finding. The full results are in the 2025 High-Net-Worth Professional Services Report.

Long Angle's weekly member polls have asked the question three ways since 2022. The wording and options differ, so the reads are not a trend line, but all three land in the same range.

Respondents are Long Angle members who chose to answer, not a representative sample of high-net-worth households. Poll answers are not linked to net worth, so no poll figure applies to a specific wealth tier. The 2022 poll is more than two years old and is shown as context.

In the January 2025 portfolio poll, 77% self-manage at least two-thirds of their portfolio, defined as stocks, bonds and alternatives, excluding directly held real estate and their own companies.

What a Wealth Manager Costs on $15M

On $15M under management, an advisor charging the 0.67% average that Long Angle respondents with $10M to $25M reported would cost about $100,500 a year. That average comes from the 2026 study, where the average AUM fee falls as household wealth rises; the full fee benchmarks by tier and fee type are on the wealth management fees page.

The fee looks small as a percentage and large against what a portfolio pays out. If you draw 3.25% a year from $15M, you take out $487,500 before tax, or about $365,625 after a 25% tax rate. The table shows how much of that after-tax draw each fee level consumes, assuming the whole $15M is managed.

Source: Fee rates are illustrative except the 0.67% row, which is the average AUM fee reported by advised respondents with $10M to $25M in net worth in the Long Angle 2026 High-Net-Worth Asset Allocation Report, 233 respondents, average net worth $17M, fielded December 2025 to January 2026. Net worth is used as a proxy for managed assets, and the band's own sample size is not stated in the report. Draw assumes a 3.25% withdrawal rate and a 25% tax rate.

That ratio is why the question gets sharper at this level. A retiree living on the portfolio feels a 0.67% fee as more than a quarter of spendable income, while someone still earning a salary and reinvesting feels it mainly as a drag on compounding. The same fee can be a reasonable price for one household and an expensive one for the next. Members who left an advisor after an exit describe exactly this shift: a fee that was easy to justify on a salary became a large drag once they were living off the portfolio.

Where Advisor-Led Portfolios Differ: Private Markets

The clearest measurable difference between advised and self-managed portfolios in Long Angle's data is private company equity. Respondents who work with a financial advisor held 18% of their investment portfolio in private company equity, against 10% for those who self-manage, and held less in public stocks.

Respondents are Long Angle members who chose to take part, not a representative sample of high-net-worth households. Investment portfolio basis, excluding home equity. Average allocation by portfolio management style.

The report attributes most of that gap to private equity fund investments. It is an association, not proof that an advisor improves results: investors who want private market exposure may seek out advisors who offer it. If private funds are the reason you are considering a wealth manager, it is worth asking which funds the firm can reach that you could not reach directly, and what the firm's fee adds on top of the fund's own fees. More on how respondents allocate by wealth tier and management style is in the 2026 High-Net-Worth Asset Allocation Report.

How Satisfied Wealth Manager Clients Are

Clients in Long Angle's 2025 survey were moderately satisfied with their wealth managers, and many were weighing a change. Wealth management averaged 7.2 out of 10 for satisfaction, and 44% of clients were considering switching providers or stopping altogether.

Source: Long Angle 2025 High-Net-Worth Professional Services Report, 114 respondents, fielded August to September 2025. Respondents are Long Angle members who chose to take part, not a representative sample of high-net-worth households. Below the 150-respondent level Long Angle uses for poll-led findings, so read as directional.

Cost was the leading complaint among respondents with an advisor. Of wealth management clients, 56% were charged a percentage of assets and 33% paid a flat annual fee, and median annual spending was $10,000. That median is well below what a full AUM fee on $15M would be, which is consistent with many clients paying flat fees or having only part of their assets managed.

The 2026 study shows the same direction of travel: 71% of advised respondents paid an AUM fee and 21% a flat annual fee.

What Members Who Left an AUM Advisor Did Instead

Members who have left an AUM advisor, or cut one back, describe the same steps in Long Angle's member discussions.

• Spinning down first. Several kept a smaller account at the old firm to hold the private funds they already owned, let those funds redeem on their own schedule, and moved the public market core elsewhere.
• Moving holdings in kind. About nine described transferring positions in kind to keep the cost basis, then selling the legacy positions over several years to spread the gains.
• Checking exit costs. Proprietary funds can carry back-end charges. Members advise asking any new advisor to avoid proprietary and illiquid products, so a later move stays cheap.
• Switching to a flat or hourly fee. The most common landing point is a flat-fee or hourly advisor for the transition or for ongoing advice, with the member placing the trades. The flat fees members cited ran from a few thousand dollars to about $12,500 a year, regardless of assets.
• Negotiating. About ten members reported negotiating their AUM rate down or urged others to try, though some found firms with a floor they would not go below.

Members with long advisor relationships make the opposite case: an advisor who knows the family's history is hard to replace. Some longtime self-managers hired one when work got harder, children arrived or retirement came closer.

When a Wealth Advisor Earns the Fee

A wealth advisor earns the fee when it does work you would not otherwise do well, at moments when getting it wrong is expensive. Investment selection alone is rarely that work at $15M, because a diversified index portfolio is cheap to run. The broader service set, which can include financial, tax, estate and retirement planning, philanthropy and investment management, is where the value tends to sit.

Three situations come up most often where full-service help pays for itself:

• After a liquidity event. Deploying a large sum for the first time, setting a tax strategy, restructuring a concentrated position and putting risk management in place. See what to do after selling your business.
• During market stress. Behavioral coaching, disciplined rebalancing and tax-loss harvesting when selling everything feels urgent.
• When the situation is complex. An international move, an equity compensation event, preparing a business for sale, an inheritance or an estate plan that needs coordinating across several professionals.

Outside those windows, the case weakens for an investor with the time and interest to run a simple portfolio. Long Angle members who found an advisor essential after an exit often describe scaling the relationship back once the plan was in place.

Continuity rarely appears in fee comparisons. At least six members in Long Angle's advisor discussions keep an advisor relationship, sometimes a deliberately small account, so a spouse who does not want to manage money has a trusted place to start if something happens to them.

In a 2024 member poll, respondents with an advisor named objectivity and emotional distance about as often as investment selection as the main benefit (21 and 22 of 97), and 7 named access to private investments. The poll drew 147 respondents and is more than two years old, so read it as context.

The Hybrid Approach Most Advised Investors Use

The most common advised arrangement in Long Angle's data is partial: 29% of respondents use an advisor for some assets, against 14% for most or all. In practice that looks like one of three setups.

• A smaller managed account. An advisor manages a slice of the portfolio, often the part tied to private fund access or a complex holding, while the investor runs the public market core through a low-cost brokerage.
• Specialists instead of a generalist. A tax-planning CPA, an estate attorney and an insurance specialist, each hired for one job, in place of one firm covering everything. See high-net-worth accountants.
• Advice without management. A flat-fee or hourly planner reviews the plan once or twice a year and the investor executes it. Flat fees do not grow with the portfolio, which removes one conflict, though service depth varies widely. The arrangement is also less common than the discussion suggests: in companion 2025 member polls, 5% of 350 respondents had any assets with an hourly or flat-fee RIA, against 30% of 356 with a traditional AUM-based RIA.

Tax-loss harvesting and direct indexing often decide which setup fits. Both can add after-tax value in high-income years, and both take work to run, which is one reason some investors keep an advisor for that sleeve and nothing else. The trade-offs are covered in Long Angle's direct indexing research.

Whichever setup you choose, the vetting matters more than the label. The questions that separate good high-net-worth financial advisors from the rest cover fiduciary status, compensation and fit.

How to Decide: Five Questions

The decision comes down to time, interest, complexity and what the fee buys you. Five questions settle it for most people:

• Do you have the time and interest to run a diversified portfolio, rebalance it and stay disciplined in a downturn?
• Is a liquidity event, retirement or other major transition coming in the next two years?
• What would the fee be in dollars, not percent, and what share of your spending does it represent?
• Do you need private market access, and could you reach the same funds without an advisor?
• Would a flat-fee planner or a few specialists cover the gaps for less?
