How much difference do regular contributions make?

Regular contributions dramatically accelerate wealth building through dollar-cost averaging and compounding. Even small monthly additions compound over time. For example, investing $500 monthly at 7% annual return yields significantly more than a single lump sum investment.

Should I increase my contribution amount or investment duration?

Time in the market is typically more powerful than amount invested due to exponential compounding growth. Starting early, even with smaller contributions, often beats starting late with larger contributions. However, both factors work together to maximize your returns.

What's a realistic annual return rate to use?

Historical stock market returns average around 10% annually before inflation, or about 7% after inflation. Conservative estimates use 6-7% for mixed portfolios, 4-5% for bond-heavy portfolios, and 8-10% for aggressive stock portfolios. Past performance doesn't guarantee future results.

How does compound interest make me wealthy over time?

Compound interest creates exponential growth. Your returns generate their own returns, creating a snowball effect. In early years, growth is modest, but in later years, your returns earn more than your contributions. This is why starting early is so powerful.

What's the Rule of 72?

The Rule of 72 estimates how long it takes to double your money. Divide 72 by your annual return rate. At 8% returns, your money doubles in approximately 9 years (72 ÷ 8 = 9). This simple rule helps you understand compound growth potential.
