|---|---|---|---|
| 10 years | $36,833 | $24,000 | +$12,833 |
| 20 years | $117,804 | $48,000 | +$69,804 |

| 40 years | $702,856 | $96,000 | +$606,856 |
Index Funds vs Individual Stocks
For beginners index funds beat individual stocks for three reasons. First diversification — an S&P 500 index fund owns 500 companies so no single failure ruins you. Second cost — index funds charge 0.03-0.20% annually while actively managed funds charge 1-2%. Third performance — over 15+ years over 90% of actively managed funds underperform their index benchmark. Individual stocks are appropriate for experienced investors with time to research companies.

How much money do I need to start investing?
You can start investing with as little as $1 through apps like Fidelity, Schwab or Robinhood. Most target-date funds and index ETFs have no minimum. The most important thing is to start early, even with small amounts.
What should a beginner invest in?
Beginners should start with a low-cost total stock market index fund or S&P 500 index fund. These provide instant diversification and have historically returned 7-10% per year over long periods.
Is it better to invest in a 401k or Roth IRA?
If your employer offers a 401k match invest enough to get the full match first — it is free money. Then max out a Roth IRA which grows tax-free. Then go back to maxing the 401k.
What is dollar cost averaging?
Dollar cost averaging means investing a fixed amount at regular intervals regardless of market prices. This reduces the risk of investing everything at a market peak and removes emotional decision making.
How long should I invest for?
The stock market historically produces positive returns over any 10+ year period. Invest money you will not need for at least 5 years. For retirement accounts aim for 20-40 years of compound growth.
