Investment Management Fees by Portfolio Size: What You Should Pay in 2025

Investment management fees are one of the most significant drags on long-term portfolio performance. A seemingly small difference of 0.50% in annual fees can cost hundreds of thousands of dollars over a 30-year investing career. Yet most investors have no idea whether the fees they pay are competitive for their portfolio size.

According to a 2024 AdvisoryHQ study, the average financial advisor charges between 0.59% and 1.18% of assets under management (AUM), with fees generally declining as portfolio size increases. But these averages hide wide variation. A $500,000 portfolio might pay anywhere from 0.25% (robo-advisor) to 1.50% (full-service wirehouse), resulting in annual costs ranging from $1,250 to $7,500.

Fee Benchmarks by Portfolio Size

The table below shows typical AUM advisory fees at each portfolio tier, based on 2024-2025 industry surveys from AdvisoryHQ, Kitces Research, and RIA Channel. Use these as benchmarks when evaluating whether your current fees are competitive.

Under $100,000

• Typical AUM fee: 1.00% to 1.50%
• Annual cost at 1.25%: $625 to $1,250
• Many traditional advisors have $100K-$250K minimums, making robo-advisors the primary option at this level
• Robo-advisor fee: 0.25% to 0.50% ($125-$500/year)
• Best option: robo-advisor (Betterment, Wealthfront, Vanguard Digital Advisor) or self-directed index fund portfolio

$100,000 to $250,000

• Typical AUM fee: 1.00% to 1.25%
• Annual cost at 1.10%: $1,100 to $2,750
• Meets the minimum for many independent RIAs and fee-only planners
• Consider fee-only advisors charging flat fees ($2,000-$4,000/year) if available, as the percentage model starts to feel expensive
• At $250,000, a 1% fee costs $2,500/year vs. $625 for a 0.25% robo-advisor

$250,000 to $500,000

• Typical AUM fee: 0.85% to 1.10%
• Annual cost range: $2,125 to $5,500
• Negotiate: many advisors will reduce fees for portfolios approaching $500,000
• At this level, the fee difference between advisor types becomes very significant
• A 0.75% fee on $500,000 saves $1,250/year compared to 1.00%

$500,000 to $1,000,000

• Typical AUM fee: 0.75% to 1.00%
• Annual cost range: $3,750 to $10,000
• Breakpoint for significant fee negotiation; you should be paying under 1.00%
• Fee-only advisors charging flat fees ($4,000-$7,500/year) become more cost-effective than AUM-based pricing
• A portfolio of $750,000 at 1.00% ($7,500/year) vs. 0.75% ($5,625/year) saves $1,875 annually
• Over 20 years at 7% returns, that $1,875 annual savings compounds to approximately $81,600

$1,000,000 to $5,000,000

• Typical AUM fee: 0.50% to 0.85%
• Annual cost range: $5,000 to $42,500
• At $2,000,000, the difference between 0.50% ($10,000) and 0.85% ($17,000) is $7,000/year
• Multi-family offices and private wealth teams typically serve this segment
• Consider whether the advisory services justify five-figure annual fees compared to a flat-fee or hourly planner plus low-cost index funds

Over $5,000,000

• Typical AUM fee: 0.30% to 0.60%
• Annual cost range: $15,000 to $30,000+
• Private banks and ultra-high-net-worth advisory firms compete at this level
• Expect comprehensive services: tax planning, estate planning, philanthropic strategy, alternative investments
• Some firms offer tiered pricing: 0.75% on the first $1M, 0.50% on $1M-$5M, 0.35% above $5M
• At $10,000,000, even 0.10% in fee difference equals $10,000/year

AUM Fees vs. Flat Fees vs. Hourly Fees

The AUM (assets under management) model charges a percentage of your portfolio, typically 0.50-1.25%. This model aligns the advisor's incentive with portfolio growth, but it also means your fee increases automatically as your wealth grows, even if the advisor's workload stays the same.

Flat-fee advisors charge a fixed annual amount, typically $2,000 to $12,000 depending on complexity. The Garrett Planning Network and NAPFA directories list fee-only planners. This model becomes more cost-effective as your portfolio grows beyond about $300,000-$500,000.

Hourly advisors charge $150-$400 per hour for specific projects (retirement plan review, tax strategy, estate planning). This works well if you need occasional advice rather than ongoing management, and it gives you complete cost control.

Robo-Advisor Fees: The Low-Cost Alternative

Robo-advisors provide automated portfolio management at a fraction of traditional advisory costs. The major platforms and their 2025 fee structures:

• Betterment: 0.25% AUM ($1,250/year on $500K), includes tax-loss harvesting and automated rebalancing
• Wealthfront: 0.25% AUM, includes direct indexing for accounts over $100K
• Vanguard Digital Advisor: 0.20% AUM ($1,000/year on $500K), uses Vanguard funds exclusively
• Schwab Intelligent Portfolios: 0% AUM advisory fee (but requires higher cash allocation)
• Fidelity Go: 0% under $25K, 0.35% above $25K, includes access to human advisors

For portfolios under $500,000, robo-advisors typically provide the best value: professional portfolio management, automatic rebalancing, and tax-loss harvesting at one-quarter the cost of a traditional advisor. The tradeoff is limited customization and no comprehensive financial planning (tax strategy, estate planning, insurance analysis).

Hidden Fees Beyond Advisory Costs

Advisory fees are just one layer of investment costs. Most investors also pay fund expense ratios, trading costs, and potentially platform fees:

• Fund expense ratios: index funds charge 0.03-0.20%, actively managed funds charge 0.50-1.50%. This is on top of any advisory fee.
• Trading commissions: most major brokerages now offer $0 stock/ETF trades, but mutual funds and options may carry fees
• Account fees: some advisors charge custodial fees, account maintenance fees, or transfer fees
• Platform fees: certain advisory platforms add technology fees on top of AUM charges
• 12b-1 fees: embedded marketing fees in some mutual funds (0.25-1.00%), effectively raising the expense ratio

Your "all-in" cost is the sum of advisory fees plus fund expense ratios plus any additional charges. A 1% advisory fee using actively managed funds with 0.75% expense ratios creates a 1.75% total drag on returns. That same portfolio using index funds (0.05% expense ratio) with a 0.25% robo-advisor has a total cost of just 0.30%.

The True Cost of Fees Over Time

Fees compound against you just as returns compound for you. The impact is far larger than most investors realize:

• $500,000 portfolio, 7% gross return, 0.25% fee: after 30 years = $3,574,000
• $500,000 portfolio, 7% gross return, 1.00% fee: after 30 years = $2,872,000
• $500,000 portfolio, 7% gross return, 1.50% fee: after 30 years = $2,427,000
• Difference between 0.25% and 1.50%: $1,147,000 over 30 years

That is $1.15 million in lost wealth from a 1.25 percentage point fee difference on a $500,000 starting portfolio. Expressed another way: the higher-fee investor must earn an additional 1.25% per year in gross returns just to match the lower-fee investor. Research from S&P Dow Jones Indices (SPIVA Scorecard) shows that 88% of actively managed large-cap funds underperformed the S&P 500 over a 15-year period, suggesting most investors are better off with low-cost index funds.

When Active Management Is Worth the Fee

Higher fees can be justified when the advisor provides value beyond basic portfolio management. Situations where paying 0.75-1.00% may be worthwhile:

• Complex tax situations: business owners, stock options, concentrated positions, multi-state income, rental properties
• Estate planning: portfolios over $1M with trust structures, charitable giving strategies, generational transfer planning
• Behavioral coaching: preventing panic selling during downturns. Vanguard's "Advisor Alpha" research estimates behavioral coaching adds about 1.5% in annual return for investors who would otherwise make emotional decisions.
• Comprehensive financial planning: coordinating tax strategy, insurance, college funding, Social Security optimization, and investment management together
• Alternative investments: access to private equity, hedge funds, venture capital, and other strategies unavailable through index funds

The key question: is the advisor providing services that generate value exceeding their fee? A tax-optimization strategy that saves $8,000/year easily justifies a $5,000 advisory fee. Basic portfolio rebalancing that a robo-advisor can do for $1,250 does not justify paying $5,000.

How to Negotiate Lower Fees

1. Know your benchmark: use the fee ranges above to understand what competitive pricing looks like for your portfolio size
2. Ask directly: "What is your fee schedule, and is there flexibility for portfolios of my size?" Many advisors have unpublished breakpoints.
3. Consolidate assets: moving all accounts to one advisor (IRA, taxable, spouse's accounts) increases your total AUM and qualifies for volume discounts
4. Reference competitors: mentioning specific robo-advisor rates (0.25%) or flat-fee alternatives gives you negotiating leverage
5. Request a fee review annually: as your portfolio grows, your percentage-based fee should decrease at published breakpoints
6. Consider a fee-only planner: switching from AUM to flat-fee pricing can save significantly on portfolios above $500,000

Bottom Line

The right fee depends on your portfolio size, complexity, and the value you receive. For portfolios under $250,000, robo-advisors (0.25%) offer the best value. Between $250,000 and $1,000,000, compare flat-fee planners against AUM-based advisors. Above $1,000,000, negotiate aggressively and expect fees below 0.75%. Regardless of portfolio size, keep your total all-in cost (advisory fees + fund expense ratios) under 0.50% when possible.
