What a Dollar-Based Flat Fee Actually Means
A dollar-based flat fee is exactly what it sounds like: a defined dollar amount based on the complexity of your financial life, the domains of planning involved, and the scope of the advisory relationship not a percentage of your portfolio balance.
If the fee is $20,000 per year and your portfolio grows from $2 million to $3 million, the fee remains $20,000. It does not increase because markets performed well. It does not escalate because your balance crossed a threshold. The fee is anchored to planning complexity and advisory scope, not to portfolio size.
This is meaningfully different from how most advisory fees are structured. Under a 1% AUM model, a $2 million portfolio generates $20,000 in fees annually. That same portfolio at $3 million generates $30,000, a $10,000 annual increase driven entirely by market appreciation, not by any additional planning work. Over 10 years, that structural difference compounds into six figures. See the detailed comparison at flat fee vs 1% AUM.
Why Most “Flat-Fee” Advisors Are Not Charging a Dollar-Based Flat Fee
The term “flat fee” is used loosely in the financial planning industry, and that imprecision creates real confusion for investors trying to evaluate their options.
There are three models commonly marketed as flat fee, and only one of them is a true dollar-based fixed fee:
Model 1 — True dollar-based flat fee
A fixed dollar amount, set at the start of the relationship, based on planning complexity and advisory scope. The fee does not change because the portfolio grew. This is what Concurrent Wealth Management charges.
Model 2 — Percentage-based flat fee (AUM-lite)
Some advisors offer a “flat” percentage that is lower than the standard 1% — for example, 0.50% or 0.65%. This is still a percentage of assets. On a $3 million portfolio at 0.65%, the fee is $19,500 annually and grows automatically as the portfolio grows. It is AUM pricing with a friendlier label.
Model 3 — Subscription or retainer fee
A monthly or annual subscription that may or may not include investment management. Some subscription models are genuinely dollar-based and fixed. Others scale with income, net worth, or portfolio size, making them variable in practice. Always confirm whether the fee is a fixed dollar amount or a variable one before signing.
When evaluating any advisor who uses the word “flat fee,” the most important question to ask is: does this fee change if my portfolio grows by $500,000 next year? If the answer is yes, it is not a dollar-based flat fee.
Fee-Only Does Not Mean Flat Fee and the Difference Matters
“Fee-only” is one of the most misunderstood terms in financial planning. It does not describe the structure of the fee. It describes the source of compensation.
A fee-only advisor earns compensation directly from clients and does not receive commissions from product sales, no insurance kickbacks, no fund company revenue sharing, no referral fees. That is a meaningful fiduciary distinction. But a fee-only advisor can still charge 1% of assets under management. The label says nothing about whether the fee is a percentage or a fixed dollar amount.
The matrix looks like this:
- Fee-only: AUM – earns no commissions, charges a percentage of assets. Very common.
- Fee-only: dollar-based flat fee – earns no commissions, charges a fixed dollar amount. Less common.
- Fee-only: subscription – earns no commissions, charges a monthly or annual subscription. Growing in popularity for younger or lower-asset clients.
- Fee-based: AUM + commission – earns fees from clients and may also earn commissions from product sales. Common at large broker-dealers.
Concurrent Wealth Management is fee-only and dollar-based flat-fee. Both distinctions matter. The fee-only designation confirms no conflict of interest from product sales. The dollar-based flat fee confirms the compensation does not grow automatically with the portfolio.
Why Dollar-Based Flat-Fee Advisors Rarely Include Investment Management
This is the gap most investors do not know exists and it is where the dollar-based flat-fee model at Concurrent differs from most of the market.
Many flat-fee advisors, including those charging a true dollar-based fee, provide financial planning only. Investment management is either excluded entirely, handled separately for an additional fee, or delegated to a third-party manager at an added cost. The planning and the portfolio operate as two separate relationships with two separate fee structures.
At $2 million to $5 million in assets, that separation creates a real problem. Tax strategy, Roth conversion timing, equity compensation decisions, and retirement income sequencing all require the planning and the portfolio to work together. When they are managed separately, decisions get made in isolation and opportunities get missed.
Concurrent Wealth Management’s dollar-based flat fee covers comprehensive financial planning with integrated investment management in one all-inclusive relationship. The planning and the portfolio are coordinated by the same advisor under the same fee. That integration is not standard in the flat-fee market, it’s the exception.
What a Dollar-Based Flat Fee Looks Like in Practice at $2M–$5M
For a high-income Gen X professional or oil and gas executive with $2 million to $5 million in assets, a dollar-based flat fee is determined by the complexity of the financial life, the number of planning domains involved, and the scope of the advisory relationship, not by portfolio size alone. At $2 million to $5 million, that typically ranges from $15,000 to $30,000 annually. At $10 million, where planning complexity across taxes, estate, equity compensation, and retirement income is meaningfully higher, the range extends to $70,000 to $100,000 annually — still a fixed dollar amount, still based on complexity and scope, not a percentage of the balance.
That fee covers:
- Comprehensive retirement income planning and sequencing
- Tax strategy and Roth conversion analysisEquity compensation planning RSUs, PSUs, stock options, deferred compensation
- Investment management across all accounts, coordinated with the overall plan
- Estate coordination and beneficiary review
- Cash flow planning and lifestyle flexibility modeling
- Ongoing behavioral guidance and decision support
The fee does not increase if the portfolio grows from $3 million to $4 million during the year. It does not reset annually based on a new asset calculation. It is reviewed periodically as the scope of the relationship evolves, but it is not tied to market performance.
For context, a 1% AUM fee on a $3 million portfolio is $30,000 annually and grows to $40,000 if the portfolio reaches $4 million. The dollar-based flat fee stays anchored. That structural difference is why the real 10-year cost comparison between the two models reaches $207,734 on a $3 million portfolio.
Four Mistakes Investors Make When Searching for a Flat-Fee Advisor
Taking the label at face value
“Flat fee” is a marketing term, not a regulatory category. Always ask for the actual dollar amount and confirm whether it changes as assets grow. If the advisor cannot give you a specific dollar figure, it is not a dollar-based flat fee.
Assuming flat fee means lower cost at every asset level
A dollar-based flat fee of $25,000 per year is more expensive than 1% AUM on a $1 million portfolio ($10,000). It becomes cost-advantaged as assets grow past $2 million to $2.5 million. Flat-fee planning is designed for investors at higher wealth levels where percentage-based pricing creates significant automatic escalation.
Not asking whether investment management is included
Many flat-fee advisors charge for planning only. If you want investment management included in the same fee and coordinated with the same advisor, confirm that explicitly before engaging. Most flat-fee advisors do not offer this.
Confusing fee-only with fiduciary
Fee-only and fiduciary are related but not identical. A fiduciary is legally required to act in the client’s best interest at all times. Many fee-only advisors are fiduciaries, but not all. Confirm both designations separately.
The Tradeoff Between Dollar-Based Flat Fees and Every Other Model
Every fee model involves a tradeoff between cost certainty and cost alignment.
AUM pricing aligns the advisor’s compensation with portfolio growth, which can feel like shared interest. But it also means the fee grows automatically regardless of whether the planning relationship became more complex or the advisor delivered more value. At $3 million and above, that automatic escalation becomes a material annual cost.
Dollar-based flat-fee pricing provides cost certainty and removes the automatic escalation. The tradeoff is that the fee does not adjust downward if markets fall, the way an AUM fee would. For investors who prioritize planning predictability and structural transparency over fee variability, the dollar-based model is typically the better fit.
The model that wins is the one that fits the investor’s planning complexity, asset level, and preference for how advisory compensation should be structured. For high-income professionals with $2 million to $5 million in assets and genuine planning complexity, the dollar-based flat fee built around comprehensive financial planning with integrated investment management is the structure most advisors in this space are not offering.
What to Do Next
If you are evaluating advisory fee structures:
- Ask every advisor you interview for their fee as an actual dollar amount, not a percentage
- Confirm whether investment management is included in that fee or billed separately
- Ask whether the fee changes if your portfolio grows by 20% next year
- Confirm fiduciary status and fee-only status separately
- Compare the real 10-year total cost of each structure, not just the annual fee

Frequently Asked Questions About Dollar-Based Flat-Fee Financial Advisors
What is a dollar-based flat-fee financial advisor?
A dollar-based flat-fee financial advisor charges a fixed dollar amount for advisory services, regardless of portfolio size. The fee is based on planning complexity and advisory scope, not a percentage of assets under management. At Concurrent Wealth Management, Dr. Preston Cherry uses a dollar-based flat fee that covers comprehensive financial planning with integrated investment management in one all-inclusive fee.
Is a fixed flat fee the same as a dollar-based flat fee?
Yes. A fixed flat fee and a dollar-based flat fee refer to the same model: a defined dollar amount charged for advisory services that does not change based on portfolio growth. Concurrent Wealth Management charges a dollar-based fixed flat fee covering comprehensive financial planning with integrated investment management, regardless of how much the portfolio grows during the year.
Is a flat fee the same as fee-only?
No. Fee-only describes the source of compensation: a fee-only advisor earns no commissions from product sales. It does not describe the fee structure. Many fee-only advisors still charge a percentage of assets under management. A dollar-based flat fee describes the structure of the fee itself — a fixed dollar amount rather than a percentage.
Does a flat-fee financial advisor include investment management?
Not always. Many flat-fee advisors provide financial planning only, with investment management excluded or billed separately. At Concurrent Wealth Management, the dollar-based flat fee covers comprehensive financial planning with integrated investment management in one all-inclusive fee. Planning and investment management are coordinated by the same advisor under the same fee structure.
What is AUM-lite and how is it different from a dollar-based flat fee?
AUM-lite refers to a percentage-based fee that is lower than the standard 1% AUM rate — for example, 0.50% or 0.65% of assets. It is still a percentage. On a $3 million portfolio at 0.65%, the fee is $19,500 annually and grows automatically as the portfolio grows. A dollar-based flat fee is a fixed dollar amount that does not change with portfolio growth, regardless of how it compares in rate to AUM pricing.
At what asset level does a dollar-based flat fee make financial sense?
A dollar-based flat fee becomes cost-advantaged compared to 1% AUM at approximately $2 million to $2.5 million in assets, depending on the specific flat-fee amount. Below that threshold, the percentage-based fee may be lower in dollar terms. Above it, the dollar-based flat fee preserves more wealth over time as the portfolio grows. At $3 million, the 10-year real total cost difference between 1% AUM and a $25,000/year dollar-based flat fee is $207,734.
How do I find a dollar-based flat-fee financial advisor who includes investment management?
Ask every advisor for their fee as an actual dollar amount and confirm that investment management is included in that fee, not billed separately. Confirm fiduciary status and fee-only status independently.
