Frequently Asked Questions

What is a good expected return for an index fund?

The S&P 500 has returned approximately 10% annually before inflation (7% after inflation) over the long term. International and bond index funds typically return less. Use 7-10% for stock index funds and 4-5% for bond index funds as reasonable projections.

How do index funds work?

Index funds track a market index like the S&P 500 by holding all (or a representative sample of) stocks in that index. They offer instant diversification, very low fees (often 0.03-0.10%), and historically outperform most actively managed funds over long periods.

What is compound interest?

Compound interest is interest earned on both the original principal and previously accumulated interest. It makes your money grow exponentially over time, which is why starting early is so powerful.

What is a realistic rate of return?

The stock market has historically returned about 10% annually before inflation (7% after). Bonds return 3-5%. A balanced portfolio might expect 6-8% long-term.
