How do I calculate future investment value with regular deposits?

Future value combines the compound principal formula with the future value of an ordinary annuity: `FV = P(1+r)^t + PMT × [((1+r)^t - 1) / r]`.

What is the historical average annual return of the stock market?

The S&P 500 index has delivered a historical long-term average annual return of approximately 10% before inflation (about 7% real return after inflation).

How does asset allocation impact investment returns and risk?

Allocating assets between equities (higher growth/volatility), bonds (income/stability), and cash preserves capital while generating growth aligned with your risk tolerance.

What is dollar-cost averaging (DCA)?

Dollar-cost averaging is investing a fixed dollar amount at regular intervals regardless of market fluctuations, buying more shares when prices are low and fewer when prices are high.

How do investment management expense ratios affect long-term wealth?

High management fees (e.g., 1% vs 0.05% index funds) can reduce total 30-year wealth by over 20% due to compounding fee drag.

How Much Will My Investment Grow Over 10, 20, or 30 Years?

Investment growth depends on initial principal, monthly contributions, annual return rate, and time. For example, investing $10,000 initially plus $500/month at an 8% annual return grows to $104,000 in 10 years, $309,000 in 20 years, and over $754,000 in 30 years due to compounding growth.
