Frequently Asked Questions
What is a realistic investment return rate?+
Historical averages: S&P 500 (10-11% nominal, 7-8% real), Bonds (3-5%), Savings accounts (4-5% currently), Real estate (7-10% total return). Use 6-8% for conservative long-term projections, 10% for aggressive equity portfolios.
How much will $10,000 grow in 10 years?+
At 7%: $19,672. At 10%: $25,937. With $500/month contributions: $92,700 (at 7%) or $123,000 (at 10%). Monthly contributions dramatically outpace the initial investment — starting early matters more than starting big.
Should I invest a lump sum or dollar-cost average?+
Lump sum wins about 2/3 of the time (markets go up more than down). Dollar-cost averaging reduces risk of investing at the top. If you have a lump sum, investing immediately maximizes expected returns. If you earn a salary, you're naturally dollar-cost averaging.
