Flat-Fee vs. AUM-Based Financial Advisors

Share

Working with a financial advisor can play an important role in shaping your long-term financial plan. However, it’s also helpful to understand how advisors charge for their services and what those fees cover. Advisors use a variety of compensation models. These include flat fees, hourly fees, subscription fees, commissions or a percentage of assets under management (AUM). Some advisors also charge separate fees specifically for financial planning services. Each pricing approach comes with tradeoffs. The structure that makes sense for you can depend on the type of services you need and your overall situation.

A financial advisor can provide insights on long-term financial planning as well as investments, budgets, and more.

How Flat-Fee Financial Advisors Work

Flat-fee financial advisors work on a set rate, usually based on several factors. Things like their experience, how often you’ll see them, and the scope of their services, all affect their rate. Some financial advisors charge an hourly rate with a retainer similar to a lawyer’s office, but that setup is rare. Most charge an upfront fee for an evaluation and strategy session. They follow this with quarterly, biannual, or annual check-ins. 

Prices will vary based on your local market and the experience of the advisor. But you may pay an average flat fee of $2,926 for a financial plan, according to a 2026 State of Financial Planning and Fees study by Envestnet. 1 The study also showed that clients paid average hourly fees of $307. Annual/retainer fees average $6,815.

The study also estimated that the average fixed percentage fee for a financial advisor is 0.96%. With a flat percentage fee, the advisor charges a set portion of the assets they manage. They calculate the fee by multiplying the account balance by the stated percentage. So if the advisor charges 0.96% on $1 million in managed assets, the annual fee would be $9,600.

Monthly subscription services have risen in popularity and are starting to be implemented by more financial advisors. These may include an upfront fee for an initial consultation followed by a monthly subscription. Some bake the cost of the initial consultation into higher monthly subscription prices. As of 2026, the average monthly subscription fee is $595 per month 

Pros and Cons of Flat-Fee Financial Advisors

Working with a flat-fee financial advisor offers a unique structure. It can be beneficial for some people but may have limitations for others. Here’s an overview of the pros and cons to help you decide if it’s the right choice for you:

Pros of Working with a Flat-Fee Financial Advisor

  • Cost transparency: Flat fees provide clear and upfront costs, so you know exactly what you’re paying without surprises. This can eliminate the complexity of other fee structures, such as asset-based fees (AUM fees). These are often a percentage of managed assets and can vary depending on your account balance.
  • No conflict of interest from asset-based fees: Flat-fee advisors are not incentivized to “push” you to keep assets under management. Their fee isn’t tied to your asset total. The advisor’s income does not depend on selling certain products or managing a larger portfolio.
  • Better alignment with client goals: Advisors charging flat fees typically focus on financial planning and holistic advice. This may better align with clients focused on comprehensive planning rather than just investments. This benefits clients who want basic financial guidance but don’t necessarily need full portfolio management.
  • Predictable and budget-friendly: A flat fee doesn’t fluctuate with the value of your investments or trading activity. This makes it easier to budget, a benefit for those on a fixed income or with limited financial flexibility.
  • Greater access to financial advice for smaller portfolios: Flat-fee structures can make financial advice more accessible. People with smaller investment portfolios might not meet the minimum asset requirements of advisors who are charged by AUM. It opens up professional financial guidance to a broader audience.

Cons of Working with a Flat-Fee Financial Advisor

It’s important to clarify service details upfront. You might end up paying a flat fee for limited advice if you don’t ask about their offerings.

  • May be more expensive for small portfolios: A flat fee may cost more than AUM-based fees depending on total assets. This can make the service seem expensive relative to their total net worth.
  • Less incentive to grow your portfolio: Flat-fee advisors don’t benefit directly from your portfolio’s growth. This may shift their focus away from maximizing investment returns. This could be a downside if you’re primarily seeking investment management rather than comprehensive financial planning.
  • Potential for lower engagement with asset management: Flat-fee advisors often focus on planning and guidance rather than active, ongoing management. This may not work for people seeking hands-on investment oversight. They may provide a plan but not necessarily monitor or adjust investments as frequently as an AUM-based advisor might.
  • Potentially high fees for high-net-worth individuals: For high-net-worth individuals, flat fees may add up to a larger overall cost than a percentage of AUM fee structure, especially if they have simple needs. Those with extensive investments might find AUM fees more economical, particularly if they desire comprehensive asset management.
  • Variability in service offerings: Flat-fee advisors can vary widely in the services they offer. They might offer limited, one-time advice or more ongoing support. Some may offer more guidance on budgeting, tax planning, or estate planning, while others may limit their scope.

How AUM-Based Financial Advisors Work

AUM-based advisors charge a percentage of the assets they manage for you.

Assets under management (AUM)-based financial advisors work by charging a percentage based on how much you have invested with them. Occasionally, different investments pay different percentages, but usually the pay comes from a percentage based on the total dollar value of your investments

AUM percentages will vary based on your local market conditions, the experience of the advisor and the types of investments they manage. Most charge around 1% of assets under management. More complex funds and investment strategies may charge a higher percentage. Some firms may drop that percentage over a certain threshold of assets, for example, charging 1% for the first million and 0.5% thereafter. 

More experienced AUM-based financial advisors will typically have a minimum investment amount to take on new clients. While you may be able to find rookie advisors willing to take on beginner investors with small portfolio balances, it can be hard to find an AUM-based financial advisor if you’re new to investing with limited assets for them to manage.

Even seemingly small percentage fees can add up to a large amount over time. In a bulletin published by the SEC’s Office of Investor Education and Advocacy, they compared the value of investing $100,000 over 20 years. They found that an account with a 1% annual fee would be worth $30,000 less at the end of 20 years compared to an account with a .25% annual fee 2

Pros and Cons of AUM-Based Financial Advisors

AUM-based financial advisors are paid based on how much you have invested, meaning that their income increases when your investments increase in value. This gives them a vested interest in how well your investments are performing, theoretically giving them greater motivation to invest your money well. 

AUM-based financial advisors receive their pay out of your investments, so you don’t have to experience the pain and hassle of paying them directly as you would with a fee-based advisor. If you can find one who will take you on when you’re new to investing, you may save money over working with a fee-based advisor. 

The biggest downside to working with an AUM-based advisor is how much their fees will cost you in the long run. 1% can easily work out to more than you would pay with a fee-based advisor and eat into your long-term investment gains.

Flat-Fee vs. AUM-Based Financial Advisors

Flat-fee financial advisors cost more for those who are new to investing but provide the same level of service as an AUM-based financial advisor for a fraction of the price once you have a moderate to large portfolio balance. If you’re new to investing and can’t afford to pay the fees for a flat-fee advisor, you may be able to find an AUM-based advisor who will take you on. 

Since an AUM-based advisor’s pay depends on your portfolio balance, they have a vested interest in your account balance growing. This could cause them to be more aggressive than you are comfortable with or recommend investments based on the percentage they will be paid if they’re paid differently for assets by the fund. 

A flat-fee advisor receives the same amount regardless of how your portfolio is doing as long as you keep using them. This may cause them to be less aggressive, so you don’t leave them after a big loss. 

Questions to Ask Before Choosing a Fee Structure

Understanding how each fee structure works in theory is different from knowing what to actually ask a prospective advisor. The following questions can help clarify what you would be paying for and whether the structure fits your situation before you commit.

What do advisors include in this fee?

Both flat-fee and AUM-based advisors vary widely in scope. Some flat fees cover comprehensive planning across budgeting, tax strategy, retirement projections, and estate considerations. Others cover a single strategy session with limited follow-up. Similarly, some AUM-based advisors include financial planning as part of their asset management fee. Meanwhile, others charge separately for planning services on top of the AUM percentage. Asking for a written breakdown of what is and is not included helps avoid costly assumptions.

Does the percentage or fee amount change at different thresholds?

Many AUM-based advisors reduce their percentage as assets grow, for example charging 1% on the first million and a lower rate above that. Flat-fee advisors may also adjust pricing based on the complexity of your situation rather than your asset level. Knowing where these breakpoints occur can help you estimate your total cost more accurately as your portfolio or planning needs change over time.

How often do advisors reassess the fee, and what triggers a change?

Flat fees tied to an annual or biannual planning cycle may increase at renewal. Advisors base these increases on added complexity, a change in your situation, or a simple standard rate adjustment. AUM fees fluctuate automatically with your account balance, which means your dollar cost can rise or fall without any change in the actual services you receive. Understanding the conditions under which your fee could change helps you avoid an unexpected increase.

What happens if my needs shift from planning to ongoing investment management, or the reverse?

Some clients start with a flat-fee planning engagement and later want more hands-on portfolio management. Others start with an AUM-based advisor and later want to scale back to occasional planning check-ins. Asking how an advisor handles that kind of transition, and whether it requires a new fee agreement, can prevent friction if your needs evolve.

Are there any additional costs beyond the stated fee?

Fund expense ratios, trading costs, account custodian fees and services like tax preparation aren’t always in the primary fee. Getting a complete picture of total costs, not just the rate, gives you a more accurate basis for comparisons.

Bottom Line

Comparing advisor fee structures can help you find an arrangement that fits your needs.

Flat-fee financial advisors typically cost less for serious investors with moderate portfolios than advisors who charge a fee based on assets under management. If you’re trying to decide between financial advisors, consider the fee structure and investment styles of each to determine which is the best fit for you.
