Investment return FAQs
Yes. You can toggle between nominal returns (actual dollars) and real returns (inflation-adjusted). With average inflation at 2-3%, real returns are typically 2-3% lower than nominal. This helps you understand true purchasing power.
Dividends can add 1-2% annually to total returns. Our calculator includes dividend reinvestment—when you reinvest dividends to buy more shares, your returns compound even faster. The S&P 500's total return with dividends is significantly higher than price-only returns.
Absolutely. Choose monthly, quarterly, or annual contributions. Monthly investing (dollar-cost averaging) often smooths out volatility and can improve long-term returns compared to lump-sum investing at market peaks.
Our tax-adjusted feature lets you input your capital gains and qualified dividend tax rate (typically 15-20%). This shows after-tax returns—crucial for comparing taxable vs. tax-advantaged accounts like Roth IRAs.
No one predicts markets perfectly. We use historical averages and Monte Carlo simulations to show a range of outcomes. Our projections are best used for goal planning and comparing strategies, not as guaranteed returns.
