How Financial Advisor Fees Work

Why the fee structure matters, not just the amount

The way an advisor is paid shapes the incentives built into the relationship. A percentage-of-assets fee ties compensation to the size of your portfolio; a commission ties it to specific products sold; a flat or hourly fee ties it to time and defined work rather than assets or products at all. None of these guarantees good or bad advice, but each creates a different set of incentives worth understanding before you sign anything.

Regulators require disclosure of these structures precisely because they matter. Both Form ADV (for investment advisers) and Form CRS (for advisers and broker-dealers) are designed to make fee structures and conflicts of interest visible in writing, and reviewing them is a normal, expected part of hiring an advisor.

Assets under management (AUM) fees

Under an AUM structure, the advisor charges a percentage of the assets they manage for you, typically billed periodically (often quarterly) and often decreasing at higher account balances through tiered pricing. This structure is common among investment advisers who provide ongoing portfolio management alongside planning.

Because the fee scales with your account balance, the advisor's compensation grows if your portfolio grows and shrinks if it declines — an alignment some clients find reassuring. It can also mean that services unrelated to investment size, like broader financial planning, are effectively bundled into a fee driven by asset size rather than by the complexity of the work involved.

Flat fees

A flat fee is a set dollar amount for a defined scope of work, such as building a comprehensive financial plan or reviewing an existing portfolio. It does not scale with account size, which can make costs more predictable and can be attractive to people with significant assets held outside what the advisor manages, or to people who want a one-time engagement rather than an ongoing relationship.

Flat-fee arrangements typically require clarity upfront about exactly what is and isn't included, since there's no ongoing percentage relationship to fall back on if the scope of work changes.

Hourly fees

Some advisors charge by the hour, similar to how an attorney or accountant might bill. This can suit people who want answers to specific questions — for example, a second opinion on a retirement drawdown strategy — without committing to an ongoing relationship or handing over asset management.

The tradeoff is that hourly arrangements depend on the client doing more of the legwork between sessions, since there typically isn't the same ongoing monitoring that comes with an AUM or subscription relationship.

Subscription (retainer) fees

A growing number of advisors, particularly those focused on planning rather than asset management, charge a recurring subscription or retainer — a fixed monthly or annual fee regardless of asset size. This model has become more common partly as a way to serve clients who don't want to hand over investment management or who have most of their assets in workplace retirement accounts the advisor doesn't directly manage.

Subscription pricing is generally more predictable than AUM fees and doesn't scale with wealth, which some clients see as more equitable and others see as less aligned with the advisor's incentive to help a portfolio grow.

Commissions

A commission is a payment the advisor or their firm receives from a third party — often a product provider — when a specific product, such as an insurance policy, annuity or certain investment fund, is sold. Commission-based compensation is common among licensed insurance agents and some broker-dealer representatives.

Commission structures mean the advisor's compensation is tied to specific transactions rather than to advice generally, which is part of why the standard of care that applies to commission-based recommendations differs from the fiduciary duty that applies to ongoing investment advice under an investment adviser relationship. See our related guide on fiduciary duty for more on this distinction.

Hybrid and combined models

Many professionals operate under more than one fee structure at once — for example, a dually registered representative might charge an AUM fee for managed accounts while also earning commissions on an insurance product recommended separately. This is legal and disclosed, but it means a single person can be compensated differently depending on which product or service is involved.

When a hybrid model is in play, it's worth asking specifically which parts of your relationship fall under which fee structure, and which standard of care applies to each piece of advice you receive.

Questions worth asking about any fee structure

• What is the exact fee structure, and can you show me in writing?
• Are there other fees layered on top, such as underlying fund expenses, custodial fees or transaction costs?
• Do you or your firm receive any compensation from third parties connected to products you might recommend?
• How and when is the fee billed, and what happens if I end the relationship partway through a period?
• If the fee structure is hybrid, which parts of the relationship fall under which structure?
