How much does a fiduciary financial advisor cost?
TL;DR. A fiduciary financial advisor typically costs between 0.50% and 1.25% of assets under management per year (the most common model), or between $2,500 and $10,000 per year on a flat retainer. Hourly rates run $200–$500; project fees run $1,500–$5,000 for a discrete plan. The headline rate matters less than what the fee covers — comprehensive planning, tax, and estate coordination vs. investment management only — and whether the portfolio itself is carrying hidden costs in the form of fund expense ratios, platform fees, or legacy products.
How much does a fiduciary advisor cost, in dollars?
Here is what a typical fee-only fiduciary relationship costs at common asset levels, assuming the most common pricing model (AUM at roughly 1.00%):
| Portfolio | Typical annual advisory fee | What's usually included |
|---|---|---|
| $250,000 | $2,500 | Investment management + 1–2 planning check-ins |
| $500,000 | $4,500 | Investment + basic retirement + tax coordination |
| $1,000,000 | $8,500 | Comprehensive planning, quarterly reviews, tax + estate coordination |
| $2,000,000 | $15,000 | Everything above + estate planning calls, insurance review, family coordination |
| $5,000,000 | $30,000–$40,000 | Family-office-light: private banking referrals, tax prep coordination, trust planning |
These are averages across fee-only advisors, not guarantees. At the high end ($2M+) many firms negotiate tiered AUM schedules that keep the effective rate below 1%, sometimes well below. At the low end (under $250K) many fee-only firms don't take AUM at all — they prefer hourly or project work because the AUM math doesn't cover the cost to serve.
Why cost structure matters more than the headline rate
Two advisors both quote "1% of assets under management." One is a fee-only fiduciary who does everything in-house and uses low-cost index funds. The other is a hybrid who earns the 1% advisory fee plus commissions on annuity sales plus trail fees on mutual funds.
On paper, both cost 1%. In reality, the first charges 1% and the second charges 1% + 1.5% in hidden drag on recommended products. Over a 30-year retirement on a $1M portfolio, the difference is approximately $850,000 in lost compounding (rough math: 1.5% annual cost differential compounded at 7% gross over 30 years).
This is why cost structure is the first question — and the headline rate is the second.
What are the four advisor fee models?
1. AUM (Assets Under Management) fee
The most common model. The advisor charges a percentage of the assets they manage for you, billed quarterly.
- Typical range: 0.50% to 1.25% per year.
- Tiered common: 1.00% on the first $1M, 0.80% on $1M–$3M, 0.60% above $3M.
- Who it fits: Clients with $500K+ who want integrated planning and investment management in one package.
- Pros: Advisor's revenue grows when your portfolio grows (alignment). Predictable cost.
- Cons: Expensive for large portfolios with simple needs. Creates conflict around "bring all your assets here" vs. "keep your 401k separate." Charges the same whether you call the advisor zero times or twenty times.
2. Flat annual retainer
A fixed annual fee, independent of assets. Often used by advisors who do comprehensive planning for business owners, professionals, or clients with complex-but-not-huge portfolios.
- Typical range: $2,500 to $10,000 per year for individuals and couples. $10,000 to $50,000+ for family-office-style service.
- Who it fits: Clients who want full-service planning but don't want their cost to scale with assets.
- Pros: Cost transparency. Advisor has no incentive to push AUM growth. Works well if your portfolio is in 401(k)s, real estate, or business equity the advisor can't directly manage.
- Cons: Not common below $400K of investable assets (the advisor's economics rarely work). Can feel "expensive" in a bad market year when your portfolio shrinks but your fee doesn't.
3. Hourly
The advisor bills time at a professional hourly rate, like a lawyer or accountant.
- Typical range: $200 to $500 per hour.
- Who it fits: Do-it-yourself investors who want a professional second opinion, or clients with discrete planning questions (a one-time retirement review, an inheritance decision, a home-sale tax question).
- Pros: You pay only for what you use. Fits the Garrett Planning Network model, which is built around hourly fee-only planning.
- Cons: Uneven annual cost. Advisor doesn't have an ongoing incentive to watch your portfolio between engagements. Can get expensive for clients who end up needing a lot of hours.
4. Project / flat-fee planning
The advisor delivers a specific deliverable — a written financial plan, a retirement drawdown strategy, a tax plan — for a fixed quoted price.
- Typical range: $1,500 to $5,000 per plan.
- Who it fits: Clients who want a one-time plan and will implement it themselves, or who want to interview an advisor's thinking before committing to ongoing engagement.
- Pros: Finite, transparent, contained. Great trial run.
- Cons: Does not include ongoing portfolio management or reviews.
What to expect at different asset levels
Under $250,000 of investable assets
AUM firms mostly won't take you, and if they do, their effective rate will likely exceed 1.25%. The best fits:
- Hourly fee-only — one-time $800–$2,500 engagement for a written plan.
- Subscription / monthly retainer — $100–$300/month for ongoing access, common among XY Planning Network advisors who serve younger clients.
- Robo-advisor + one annual human review — robo-advisor at ~0.25% AUM plus a $500–$1,500 annual planning review.
$250,000 to $1,000,000
The AUM sweet spot. Expect:
- Advisory fee: 0.85% to 1.10% per year.
- Relationship: 2–4 planning meetings per year, investment management, tax coordination with your accountant, one annual deep-review meeting.
- Alternative: Flat retainer of $4,000–$8,000 if your portfolio is fragmented across 401(k)s, real estate, and business equity.
$1,000,000 to $3,000,000
Competitive tier. Every fee-only firm wants you. Expect:
- Advisory fee: 0.70% to 1.00% on the first $1M, declining above that.
- Relationship: Quarterly meetings, comprehensive tax planning, estate planning coordination, insurance audit, trust and gifting strategy.
- Alternative: Flat retainer $10,000–$20,000, especially if you have business equity, concentrated stock, or an international life.
$3,000,000 and above
- Advisory fee: Effective rate drops below 0.70%. Most firms offer tiered pricing that puts you in the 0.40%–0.65% range on the margin.
- Relationship: Approaches family-office service. Tax prep may be included or done at cost.
- Alternative: Some clients move to multi-family-office ("MFO") firms at flat annual fees of $30,000–$75,000 that include tax, trust, and reporting.
What's bundled vs what's extra
"1% AUM" does not mean "1% covers everything." Confirm in writing what is included:
| Service | Typically included? |
|---|---|
| Investment management | Yes |
| Quarterly performance reporting | Yes |
| Planning meetings (2–4/year) | Usually |
| Retirement drawdown analysis | Usually |
| Social Security optimization | Usually |
| Tax planning (not prep) | Usually for fee-only firms |
| Tax return preparation | No — typically $400–$2,000 extra through a partner CPA |
| Estate plan drafting | No — attorney fees, $1,500–$7,500 |
| Insurance review | Yes, but implementation is separate |
| Concentrated-stock strategy | Usually bundled at $1M+ |
| Trust reviews | Separate for complex trusts |
Hidden costs that eat into returns
The advisor's fee is the tip of the iceberg. Portfolios carry other costs you must also account for:
- Fund expense ratios. The mutual funds and ETFs in your portfolio charge their own fees annually. Index funds: 0.03%–0.15%. Actively managed funds: 0.50%–1.20%. Target-date funds: 0.10%–0.75%. A portfolio of expensive actively managed funds can cost another 0.75%+ on top of the advisory fee.
- Platform / custodian fees. Most fee-only advisors custody through Schwab, Fidelity, or Altruist, where trading and account fees are $0 for clients. But some firms still use platforms that charge 0.05%–0.20% in wrap fees.
- Mutual fund 12b-1 fees. If your portfolio contains older share classes from a prior brokerage relationship, 0.25%–1.00% trail fees may still be flowing to someone. A fee-only advisor should convert these to clean share classes at onboarding.
- Annuity M&E and rider fees. If you own a variable annuity, expect 1.00%–2.50% in annual drag from mortality & expense charges and rider fees.
- Proprietary-product markups. Not a concern with fee-only advisors. Common at wirehouses.

Is a fiduciary advisor worth the cost?
A reasonable benchmark for a good fee-only fiduciary is that the relationship should pay for itself in tax savings + behavioral coaching + avoided mistakes, with the investment returns roughly matching what you'd earn on your own.
Vanguard's "Advisor's Alpha" research, most recently updated in 2022, estimates that competent advisory relationships add roughly 3% per year in net value to a typical client — most of which comes from behavioral coaching during market drawdowns and tax-efficient withdrawal sequencing, not from stock-picking.¹ Morningstar's "Gamma" research finds a similar-sized benefit from retirement-income planning alone.²
If your advisor fee is 1% and the relationship delivers 3% in added value, you are paying one to net two. That math breaks when:
- Your portfolio is simple (e.g., a 60/40 target-date fund with no tax complexity), and a robo or DIY approach could deliver the same outcome.
- The advisor is fee-based rather than fee-only, and the extra 1–2% in product drag cancels the 3% Advisor's Alpha.
- Market years are flat or up, and the advisor doesn't reach out (which happens more than you'd expect — hold them to a service-level standard).
If any of those is true, renegotiate or leave.
How to know if you're overpaying
Three tests:
- Total-cost ratio test. Add advisory fee + weighted fund expense ratios + platform fees + product-specific fees. If the total exceeds 1.50% of assets per year for a standard portfolio, you are probably overpaying. Above 2.00% is a clear signal to renegotiate or switch.
- Service-level test. Count the planning meetings and tax-planning touchpoints you got in the last 12 months. If you paid $8,000 and got two emails and one 30-minute review, you overpaid.
- Comparison test. Get a fee quote from one fee-only competitor at the same asset level. If they quote 30%+ below what you're paying for equivalent service, the market has moved and yours hasn't.
Key takeaways
- Typical fee-only fiduciary: 0.85%–1.10% AUM, or $2,500–$10,000 flat retainer.
- Cost structure matters more than the headline rate. Fee-based advisors' total cost is often 2x the quoted rate.
- Under $250K, AUM math rarely works — look for hourly or subscription fee-only.
- Bundle confirmation in writing: what's included, what's extra, and at what price.
- Benchmark your total cost (advisory + funds + fees). Over 1.5%/year is a warning sign.
- Vanguard and Morningstar both put good advisory value at ~3%/year. Fee-only advisors deliver that math. Fee-based often don't.
