Should I use index funds or hire a financial advisor?

Index funds for most people. A low-cost three-fund portfolio (US stocks, international stocks, bonds) charges 0.03–0.10% in fees and has outperformed 90% of professional fund managers over 15+ years. A financial advisor (typically 1% AUM fee) is worth it only for complex situations: large inheritance, business exit, multi-state taxes, or estate planning.

Formula

Fee impact: $500k × 1% fee × 30 years = ~$316k lost to fees vs. 0.05% index fund (at 7% return).

Example

DIY: $500k in VTI (0.03%) for 30 years at 7% → $3.76M. With advisor (1% fee): $500k at 6% effective → $2.87M. Difference: $890k. Advisor must generate >1% alpha annually to break even.

How it works in detail

The math is devastating for active management: a 1% annual fee on $500k over 30 years at 7% returns costs $316,000 in lost compounding vs. a 0.05% index fund. That's 63% of an additional portfolio's growth consumed by fees. Vanguard, Fidelity, and Schwab offer target-date funds or three-fund portfolios for <0.10%. However, an advisor earns their fee in specific scenarios: tax-loss harvesting on large portfolios, Roth conversion optimization, asset location strategy, behavioral coaching (preventing panic selling), and complex estate planning. A fee-only fiduciary advisor (flat fee, no commissions) is the only type to consider.
