Frequently Asked Questions
Historical stock market returns average 7-10% annually over long periods. Conservative estimates use 6-7%, while aggressive growth strategies might expect 8-12%. Consider your risk tolerance, investment mix, and time horizon when setting expectations.
More frequent compounding (daily vs. annually) increases returns slightly, but the effect diminishes with higher frequencies. The difference between monthly and daily compounding is minimal, while the difference between annual and monthly compounding is more noticeable.
Inflation erodes purchasing power over time. A 3% inflation rate means $100 today will only buy $74 worth of goods in 10 years. Your investments need to outpace inflation to maintain and grow your real wealth.
Even small fees compound over time. A 1% annual fee can reduce your final portfolio value by 20-25% over 30 years. Low-cost index funds (0.1-0.5% fees) often outperform actively managed funds (1-2% fees) after accounting for fees.
Yes, increasing contributions with salary raises or inflation helps maintain your savings rate and accelerates wealth building. Even a 3% annual increase can significantly boost your final portfolio value due to the power of compound growth.
