Question 1

What is compound growth and why does it matter?

Accepted Answer

Compound growth means your returns generate their own returns. If you invest $10,000 at 10% annual return, you earn $1,000 in year 1. In year 2, you earn 10% on $11,000 ($1,100), and so on. Over 30 years, that initial $10,000 grows to $174,494 — without adding a single dollar. This exponential effect is why starting early is the single most impactful financial decision you can make.

Question 2

What is a realistic annual return to expect?

Accepted Answer

The S&P 500 has returned approximately 10% annually on average since 1926 (about 7% after inflation). However, this includes years of 30%+ gains and years of 30%+ losses. A diversified portfolio of stocks and bonds typically returns 6-8% long-term. Conservative investors should model 5-7%, while aggressive investors might use 8-10%.

Question 3

How does inflation affect my investment returns?

Accepted Answer

Inflation erodes purchasing power over time. If your investments earn 10% but inflation is 3%, your "real" return is approximately 7%. Over 30 years, $1 million in nominal terms might only buy what $412,000 buys today. Always consider inflation-adjusted returns when planning for long-term goals like retirement.

Question 4

Should I invest a lump sum or dollar-cost average?

Accepted Answer

Historically, lump-sum investing outperforms dollar-cost averaging about 2/3 of the time because markets tend to rise. However, dollar-cost averaging (investing fixed amounts regularly) reduces the risk of investing everything at a market peak and is psychologically easier. For most people with regular income, automatic monthly contributions are the best approach.

Question 5

What are index funds and why do experts recommend them?

Accepted Answer

Index funds track a market index (like the S&P 500) and provide instant diversification across hundreds of companies. They have very low fees (0.03-0.20% annually) compared to actively managed funds (0.50-1.50%). Research consistently shows that most actively managed funds underperform index funds over long periods. Warren Buffett himself recommends low-cost S&P 500 index funds for most investors.

Question 6

What is the difference between nominal and real returns?

Accepted Answer

Nominal returns are the raw percentage your investment grows. Real returns subtract inflation to show actual purchasing power growth. If your portfolio gained 8% this year but inflation was 3%, your nominal return is 8% but your real return is approximately 4.8%. When planning for future goals, real returns give a more accurate picture of what your money will actually buy.
