Flat Fee Financial Planning: Why Business Owners Are Making the Switch

The Problem With Traditional AUM Pricing

Assets Under Management pricing sounds simple: pay 1% of your portfolio annually, and your advisor manages it. Straightforward.

A percentage fee can create incentives that deserve discussion, including how recommendations affect billed assets. Those incentives should be disclosed and evaluated alongside the service.

How AUM creates misaligned incentives

Under AUM, your advisor's revenue is directly tied to the size of your investment portfolio. This creates a powerful incentive: grow your portfolio, and the advisor's fees grow proportionally.

Sounds fine, right? The problem surfaces when you consider what's best for you:

• Advice that costs money but saves you more: "You need a $50K buy-sell agreement." If that insurance isn't managed as investments, the advisor doesn't earn fees on it—so there's no financial incentive to recommend it.
• Tax strategy over investment growth: "You should take capital losses this year to offset gains." That strategy shrinks your portfolio temporarily, which shrinks the advisor's fees. Under AUM, the incentive runs the other direction.
• Business optimization over stock picking: "You should reduce hours and spend time on CPA training to minimize your taxes." That's not investment management, so it generates no advisory fees. But it might be the best use of your time.
• Entity restructuring: Switching from a C-corp to S-corp, or vice versa, might save $30K in taxes annually. But it has nothing to do with investment accounts, so the AUM advisor has no incentive to suggest it.
• Diversifying out of your business: "Sell 20% of your company and invest the proceeds." Good advice. But if your business is already 70% of your net worth, the advisor might actually prefer you keep it that way—less investable assets on their books, but at least the portfolio they do manage can be larger.

The problem with AUM isn't that advisors are dishonest. It's that the fee structure creates incentives that don't align with your best interests over the long term.

The Math: What You're Actually Paying

Let's walk through a real scenario. You're a business owner with $1 million invested and $2 million in the business (total net worth $3M).

Scenario 1: AUM at 1%

• Annual fee: $10,000 (1% of $1M in investments)
• Assumes 7% annual portfolio return
• After 20 years: portfolio grows to $3.9M, but you've paid $298,000 in advisor fees
• Real cost: About 7.1% of your total return went to fees

Scenario 2: Flat fee $5,000/year

• Annual fee: $5,000 fixed
• Same 7% portfolio return
• After 20 years: portfolio still $3.9M, but you've paid $100,000 in advisor fees
• Real cost: About 2.4% of your total return went to fees

Over 20 years, the flat-fee advisor saved you $198,000 while delivering the same investment results. And because the fee wasn't tied to portfolio size, they had no perverse incentive to keep you from making tax-optimal decisions that might temporarily shrink your assets.

The AUM premium grows as you scale

This advantage amplifies if your business grows and your investable assets increase. If you're a $500K revenue business owner with $2M invested, and AUM is 1%, you're paying $20,000 per year—money that could go into tax-advantaged accounts, your emergency fund, or opportunities you spot.

Flat Fee vs. AUM vs. Hourly: A Real Comparison

AUM pricing

Cost: 0.5% to 1.5% of assets annually

Pros: Simple, scales with your wealth (in theory, as you grow richer, fees grow too—but that's actually backwards), established model

Cons: Incentivizes keeping money invested rather than spending it, disincentivizes tax-loss harvesting or major rebalancing, doesn't account for the complexity of your business, fees compound forever

Hourly billing

Cost: $200 to $600+ per hour, typically billed in quarterly or annual retainers ($10K-$50K+/year)

Pros: You pay for time spent; if you only need 5 hours of advice, you pay for 5 hours

Cons: Incentivizes long meetings and busy work; advisor may rush if they're over-committed; hard to know total cost upfront; not great for ongoing portfolio management

Flat fee (retainer)

Cost: Fixed annual fee, typically $5,000 to $30,000+ depending on complexity

Pros: Aligns incentives (advisor benefits when you succeed, regardless of portfolio size), transparent cost, no incentive to bloat your portfolio, works well for business owners with concentrated assets, can include unlimited access

Cons: Higher upfront cost for simple situations; must vet advisor carefully to ensure they're not skimping on work to hit margin targets

Why Flat Fee Aligns Better for Business Owners

Business owners face complexity that W-2 employees don't: concentrated assets, tax optimization across business and personal income, entity structure decisions, succession planning, and exit strategy.

Under flat-fee pricing, your advisor's incentive is to solve your problems comprehensively, not to manage a larger investment bucket. If the best move is to restructure your business entity and reduce your AUM temporarily, the advisor recommends it—because their fee doesn't change.

Real scenario: The entity restructuring decision

You operate as a C-corp and realize you'd save $15,000 annually in taxes as an S-corp. The conversion costs $5,000 in legal and accounting fees, reduces your business profit on paper by 10% for one year (temporarily shrinking your investable assets), but saves you $150K over 10 years.

Under AUM: Your portfolio shrinks from $1.5M to $1.35M. Your advisor's annual fee drops from $15,000 to $13,500. Over 10 years, that's $15,000 in lost fees. An AUM advisor should disclose the fee effect and still evaluate the decision on its planning merits.

Under flat fee: Your fee stays the same. The advisor has zero incentive to delay the decision. If it saves you money, you implement it, and the advisor's job is to help you manage the process.

What to Expect From a Flat-Fee Engagement

If you're transitioning from AUM to flat-fee, here's what a good engagement looks like:

Year one: The deep dive

• Comprehensive financial plan covering investments, taxes, business structure, insurance, and succession
• Multiple strategy sessions and meetings
• Review of business financials and valuation
• Coordination with CPA and legal advisors
• Concrete recommendations with implementation timeline

Ongoing: Annual reviews and updates

• Annual planning meeting to review performance and adjust strategy
• Rebalancing as needed (not constrained by fee structure)
• Tax planning sessions before year-end
• Availability for ad-hoc questions and minor updates
• Coordination with your team (CPA, attorney, business advisors)

What's typically NOT included

Clarify upfront what's in scope: Are we managing your personal investments? Your business retirement plan? Your spouse's accounts? Most flat-fee advisors carve out clear boundaries.

How to Choose Between Pricing Models

Ask yourself:

• How complex is your situation? If you have a business, concentrated assets, business partners, or complex tax issues, flat-fee usually wins. You need comprehensive advice more than you need investment management.
• What's the advisor's incentive with this fee model? Under AUM, they want your portfolio to grow. Under flat-fee, they want to solve your problems and keep you as a client. Which matters more to you?
• Will you follow their advice? If an advisor recommends something that costs fees in the short term (like selling part of your business to diversify), do you trust they're saying it for your benefit, not theirs?
• How much advice do you actually need? If it's 10-15 hours per year, flat-fee is probably cheaper. If it's 2 hours per year, you might be better off with hourly.

Why Some Business Owners Consider Flat Fees

It's not because flat-fee advisors are newer or trendier. It's because business owners eventually figure out what economists have known for decades: fee structure matters.

When your advisor's paycheck depends on portfolio size, they're incentivized to focus on investments rather than your business, your taxes, your succession plan, or your exit strategy. Those are the conversations that move the needle for business owners—and they're the conversations that AUM pricing discourages.

Flat-fee advisors solve that problem by removing the conflict. Your success is their success—regardless of whether success looks like growing investments, optimizing taxes, restructuring your business, or preparing to exit.
