Frequently Asked Questions

What are historical market returns?+

The US stock market has historically averaged about 10% annually (nominal), or 7% after inflation. Bonds average 5-6%. These are long-term averages - individual years vary widely.

How do fees affect investment returns?+

Fees directly reduce returns. A 1% fee reduces your final balance by about 25% over 30 years. Low-fee index funds at 0.1% outperform actively managed funds charging 1%+ after fees.

How often should I rebalance?+

Annually, or when allocations drift more than 5% from target. Rebalancing maintains risk levels and enforces "buy low, sell high". Rebalancing too often triggers taxes and trading costs.

How do taxes affect returns?+

Taxes significantly reduce net returns. In taxable accounts, capital gains and dividends are taxed annually. Use tax-advantaged accounts (401k, IRA) for long-term investing to defer or avoid taxes.
