How to Start Investing With $100

You don't need a lot of money to start. Here's the exact path for a beginner:

  1. Open a Robinhood or Fidelity account — takes 5 minutes, no minimum
  2. Buy one S&P 500 index fund (VOO or SPY) — instant diversification
  3. Set up $25–$50 automatic weekly deposit — consistency beats timing
  4. Don't touch it — the S&P 500 has returned ~10%/year on average over any 20-year period
Our Verdict

For most people: Robinhood to start (free stock bonus + easy UI), then move serious retirement savings to Fidelity (zero-fee index funds). Add Acorns if you want completely passive micro-investing on top.
