Expense Ratio ImpactFormula
A 1% annual fee on a $100,000 portfolio over 30 years at 7% return costs ~$590,000 in lost compounding versus a 0.1% fee fund.
Keep Costs Low
Expense ratios are the most reliable predictor of fund performance. Low-cost index funds outperform 80%+ of active managers over 15+ years.
Do Not Time the Market
Missing the 10 best trading days in a decade cuts returns in half. Stay invested and rebalance systematically instead.
Use Tax-Advantaged Accounts First
Max out 401(k) and IRA contributions before investing in taxable accounts. Tax deferral or exemption compounds significantly over decades.
Write an Investment Policy Statement
Document your allocation targets, rebalancing rules, and reasons for each holding. Refer to it during market panics to avoid emotional decisions.
Safety Notes
- Never invest money you cannot afford to lose in the short term — maintain 3-6 months of expenses in cash before investing.
- Be skeptical of guaranteed high returns, unregistered investments, and pressure to act quickly — these are common signs of investment fraud.
