How much does a financial advisor cost?

AUM-based advisors charge 0.5-1% of assets annually ($5,000-$10,000/year on $1 million). Fee-only advisors charge $150-$400/hour or $1,500-$7,500 for a comprehensive plan. Robo-advisors charge 0.25-0.50% ($2,500-$5,000/year on $1 million). Commission-based advisors are 'free' but earn from product sales.

What is a fiduciary financial advisor?

A fiduciary is legally required to act in your best interest, not their own. Fee-only advisors (CFP, RIA) are fiduciaries. Commission-based advisors at brokerages have a lower 'suitability' standard. Always ask: 'Are you a fiduciary 100% of the time?'

Do I need a financial advisor?

Most people with simple finances (W-2 income, basic investing) can manage their own money with index funds and basic tax planning. Consider an advisor if you have complex taxes, stock options, estate planning needs, a financial windfall, or you simply don't want to manage your own investments.

“What’s your investment philosophy?”	Evidence-based, diversified, low-cost	Active management, proprietary products

Advisor vs. Robo-Advisor vs. DIY

Factor	Human Advisor	Robo-Advisor	DIY
Annual cost ($500K portfolio)	$3,750-$5,000	$1,250-$2,500	$150 (fund fees)
Personalization	High	Low-Medium	You decide
Tax optimization	High (if competent)	Medium (tax-loss harvesting)	Self-directed
Behavioral coaching	Yes (big value)	Automated rebalancing	Must self-manage
Estate/insurance planning	Yes	No	Self-directed
Best for	Complex situations, $500K+	Simple investing, $50K-$500K	Knowledgeable investors

The Bottom Line

Most people with straightforward finances can manage their money with a simple 3-fund index portfolio and no advisor. If your situation is complex (stock options, business income, estate planning, or $500K+), a fee-only fiduciary advisor can save you far more than they cost. Avoid commission-based advisors who earn money selling products. If you hire someone, always ask: “Are you a fiduciary 100% of the time?”
