1. Why You Should Start Investing in 2025
Inflation is rising, savings account interest is still low, and pensions are nearly extinct. In 2025, building wealth means making your money work for you.
Investing helps you:
- Beat inflation (U.S. CPI at ~3.4% in early 2025)
- Retire comfortably without relying only on Social Security
- Grow money passively via stocks, ETFs, or real estate
- Achieve financial independence sooner than later
Even if you only have $100 now, the key is to start.
2. Does It Really Make Sense to Start with Just $100?
Yes—and here’s why:
- Platforms like Robinhood, Fidelity, SoFi, Webull, and Charles Schwab allow fractional shares
- Index funds like VTI or SPY let you invest in 100s of companies for under $10
- Crypto platforms like Coinbase and Kraken offer partial coin purchases
- Real estate apps like Fundrise or Arrived allow investments starting at $10–$100
$100 may not make you rich—but it starts your habit and grows your confidence.
3. The Power of Compound Growth
Investing early—even small amounts—allows compounding to work its magic.
Example:
- $100 invested at 8% annual return for 30 years = $1,000+
- If you add just $25/month, that grows to over $30,000
