Frequently Asked Questions
What is a realistic investment return?
The S&P 500 has historically returned about 10% annually before inflation, or about 7% after inflation. Individual stocks vary widely. Bonds return 3-5%. Real estate averages 8-12% with leverage.
How much should I invest per month?
Most experts recommend investing 15% of your income. Even $200/month invested at 7% annual return becomes about $244,000 after 30 years. Start small and increase contributions over time.
What is dollar cost averaging?
Dollar cost averaging means investing a fixed amount regularly regardless of market conditions. When prices are low, you buy more shares. When high, you buy fewer. It reduces the risk of investing a lump sum at the wrong time.
When should I start investing?
As early as possible. Due to compound interest, starting at 25 vs 35 can double your retirement savings. Even investing small amounts early beats larger amounts later.
What is the difference between stocks and bonds?
Stocks represent ownership in companies with higher potential returns and higher risk. Bonds are loans to companies or governments with lower returns and lower risk. A diversified portfolio typically holds both.
