You don't need thousands to begin building wealth through investing.

Start Investing with Just $100

The biggest myth about investing is that you need a lot of money to start. You don't.

Step 1: Open a Brokerage Account

Choose a commission-free broker like Fidelity, Schwab, or Vanguard. Most have no minimum balance requirements.

Step 2: Choose Your First Investment

With $100, buy a broad market ETF like VTI (Vanguard Total Stock Market) or VOO (S&P 500). You get instant diversification across hundreds of companies.

Step 3: Set Up Automatic Investing

The real power comes from consistency. Set up automatic weekly or monthly purchases, even if it's just $25 at a time.

Step 4: Don't Touch It

The hardest part of investing is doing nothing. Market drops are normal. Stay the course and let compound interest work its magic.

The Math of $100/Month

• After 10 years (10% avg return): ~$20,655
• After 20 years: ~$75,937
• After 30 years: ~$226,049
