Frequently Asked Questions
What rate of return should I assume?
Historical averages (1928–2024): S&P 500 total return ~10% nominal, ~7% real (after inflation). Bonds: 4–5% nominal. A balanced 60/40 portfolio: 7–8% nominal long-term. Use 6–7% for conservative planning, 8–10% for optimistic.
How does compounding affect my result?
Compounding turns small rate differences into large dollar differences over decades. $10,000 at 7% over 30 years = $76,123. The same amount at 9% = $132,677 — 75% more from a 2% rate difference. Time horizon and rate matter more than starting amount for long-term growth.
Should I include inflation?
If you want today's purchasing power, subtract ~2.5% from your nominal return rate to get a real return. The calculator shows nominal future value; mentally divide by (1.025)^years to translate to today's dollars.
What about taxes?
Pre-tax accounts (401(k), traditional IRA): no tax on growth, taxed on withdrawal at ordinary rates. Roth: taxed on contribution, no tax on growth or withdrawal. Taxable accounts: long-term capital gains taxed at 0/15/20%, dividends often qualified. Use the Capital Gains Calculator to model tax impact.
