Frequently Asked Questions
What's a realistic expected return rate?
Historical S&P 500 returns average 7-10% annually before inflation. Conservative investments like bonds typically yield 2-4%, while savings accounts offer 0.5-2%. Your actual returns depend on your investment strategy and market conditions.
How does compound interest work?
Compound interest means you earn returns on both your original investment and the accumulated interest from previous periods. This creates exponential growth over time, making it significantly more powerful than simple interest for long-term investments.
Why account for inflation and taxes?
Inflation reduces purchasing power over time, so $1,000 today won't buy the same amount in 20 years. Taxes reduce your actual investment gains. Considering both factors gives you a realistic picture of your investment's real value and growth potential.
