Financial Advisor Minimum Investment: Why AUM Minimums Exist — and How to Find Advice Without One

Not tax or investment advice. This page explains how advisor minimum thresholds work so you can evaluate your options as a consumer.

The most common first question people ask when looking for a financial advisor: "How much do I need to have?" The honest answer depends entirely on what type of advisor you're asking about.

AUM (assets under management) advisors typically require $250,000 to $1,000,000 or more in investable assets before they'll take you as a client. Flat-fee and hourly advisors generally have no meaningful minimum — their fee doesn't depend on portfolio size.

Understanding why AUM minimums exist is the key to finding advice that actually fits your situation.

Why AUM advisors have minimum investment requirements

AUM advisors charge a percentage of the assets they manage — typically 0.75%–1.25% per year. This creates an economic floor for the relationship:

• At $250,000 in assets, an advisor charging 1% earns $2,500/year from you
• At $500,000, they earn $5,000/year
• At $1,000,000, they earn $10,000/year

Running a client relationship — meetings, planning, reporting, compliance — costs an advisory firm roughly $2,000–$5,000/year per client in overhead, depending on complexity. Below a certain portfolio threshold, the client relationship isn't economically viable for the firm. The minimum investment requirement is simply a breakeven calculation dressed as a client qualification standard.

This is a structural feature of the AUM model, not a judgment about whether you need or deserve financial advice.

Typical AUM minimums by firm type

Minimums reflect industry surveys as of 2026. Verify any specific advisor's minimum in their Form ADV Part 2A before assuming you qualify.

What AUM minimums actually filter for — and what they miss

AUM minimum requirements filter for portfolio size, not financial complexity. These are not the same thing.

Someone with $400,000 in retirement accounts, a $350,000 business, equity compensation vesting over three years, and aging parents who may need care support has significant financial complexity — and may be turned away by AUM advisors with a $500K minimum because none of that is in their investable AUM count.

Someone with $2,000,000 in a single target-date fund and no other complexity may pay $20,000/year in AUM fees for what amounts to very little active planning value.

AUM minimums sort for one dimension of the client relationship — revenue potential — while the actual need for advice is driven by a different dimension: complexity, transitions, and decisions with long-term consequences.

Flat-fee and hourly advisors: why no minimum is needed

A flat-fee advisor charges a fixed annual retainer — say, $5,000/year — regardless of whether you have $400,000 or $4,000,000 in assets. Their revenue doesn't scale with your portfolio size, so there's no economic floor that forces a minimum.

The same logic applies to hourly advisors: if they charge $400/hour and you need four hours of work, you pay $1,600. That transaction makes economic sense at $200,000 in assets just as well as at $2,000,000.

This is a meaningfully different filter. Many flat-fee advisors work with clients who have $300,000–$800,000 in assets and find the flat-fee model produces better outcomes than they'd get from an AUM advisor at $1M+ — because the fee is lower, the conflicts are removed, and the planning is more comprehensive.

The real question: when does advice become worth paying for?

Portfolio size is a poor proxy for "do I need advice?" The better diagnostic is financial complexity and decision quality. Consider whether any of these apply to your situation:

For many of these situations, a flat-fee or hourly engagement costs $1,500–$8,000 and produces specific, actionable guidance. That compares favorably to AUM fees of $10,000–$30,000/year for ongoing management at larger portfolio sizes — especially when the planning component at AUM firms often receives less attention than the investment management piece.

What "minimum investable assets" means — and common misconceptions

A few clarifications on terms that cause confusion:

"Accredited investor" status is not a financial planning threshold. Accredited investor status ($1M+ net worth excluding primary residence, or $200K+ income) is a securities law designation governing access to private placements, hedge funds, and certain alternative investments. It has nothing to do with whether you can work with a financial advisor for planning purposes.

Your 401(k) balance often doesn't count toward AUM minimums. Most AUM advisors manage assets held at custodians they control — typically rolled-over IRAs or taxable brokerage accounts. Your employer 401(k) balance usually isn't included in their AUM, meaning a $500K 401(k) and $200K in personal savings might not meet a $500K minimum even though your total investable assets are $700K.

Home equity, business value, and deferred compensation are generally excluded. AUM is specifically investable financial assets that can be transferred to the advisor's custodian. Real estate equity, business interests, unvested equity, and NQDC plan balances typically don't count — which further distorts AUM minimums as a proxy for financial complexity or need for advice.

How to find fee-only advisors who work without a minimum

Three directories are the best starting points:

• NAPFA (napfa.org): National Association of Personal Financial Advisors — all members are fee-only (no commissions, no third-party compensation). NAPFA members include advisors who work on hourly and flat-fee retainer models with no minimum.¹
• XY Planning Network (xyplanningnetwork.com): Fee-only network with many advisors who serve clients in the $100K–$1M range that AUM firms underserve. Includes filters for advice-only, hourly, and subscription-based models.²
• Garrett Planning Network (garrettplanningnetwork.com): Hourly and project-based fee-only advisors. The founding purpose of Garrett was specifically to serve middle-income and pre-affluent clients that AUM firms turned away.³

When evaluating any advisor, verify their compensation structure in their Form ADV Part 2A, Item 5 via the SEC's IAPD database (adviserinfo.sec.gov). If you see AUM-based compensation, confirm whether they have a minimum — and whether it applies to you based on how they count eligible assets.⁴

Specific questions to ask about minimums

1. Do you have a minimum portfolio size to work with you? If so, how do you count toward it — does my 401(k) balance at Fidelity count?
2. If I'm below your typical minimum, is a minimum annual fee available instead of a percentage-based arrangement?
3. Is your fee structure flat, hourly, or percentage-based — and does any part of your compensation scale with my portfolio size?
4. For a client with [your situation], what would an engagement typically cost and look like?
