Frequently asked questions.
How do compound returns affect investment growth?
Compound returns create exponential growth because you earn returns not only on your initial investment but also on previously accumulated returns. Over long periods, this dramatically increases your portfolio value.
What is a realistic annual return rate for investments?
Historically, the S&P 500 has returned approximately 10% annually before inflation, or about 7% after inflation. However, past performance does not guarantee future results.
