Frequently Asked Questions

❓ How do regular contributions affect investment growth?

Regular contributions (like saving $200 a month) significantly boost your future portfolio value by continuously increasing the principal balance, which in turn generates larger compound interest returns each compounding cycle.

❓ What is a realistic annual rate of return for calculations?

For long-term stock market investments, a historical average annual return of 7% to 10% (before inflation) is commonly used. However, returns fluctuate, and it is wise to run conservative estimates (e.g., 5% to 6%) to plan safely.

❓ How does inflation affect my investments?

Inflation reduces the purchasing power of your money over time. If inflation is 3% and your investment returns 8%, your real inflation-adjusted rate of return is approximately 5%.

❓ What is the difference between stocks, bonds, and cash?

Stocks represent ownership in companies and offer high potential returns with high risk. Bonds are loans to governments or corporations offering moderate returns with lower risk. Cash (savings accounts/CDs) offers low returns with virtually no risk of principal loss.
