How to Start Investing With Just $100

There’s a common myth that you need thousands of dollars to get started in the stock market. The truth? You can start investing with as little as $100 — and that small start could make a big difference over time.

This guide will show you how to put your first $100 to work, even if you’ve never invested before.


Why Start With $100?

You might think $100 isn’t enough to matter. But here’s why it’s a powerful place to begin:

  • Build the habit: Starting small helps you create an investing routine.
  • Time in the market matters more than timing the market.
  • Learn by doing: You’ll understand more once your money is working for you.
  • Compound growth: That $100 can turn into thousands over decades.

Even if you never invest another penny, starting now gets your money growing.


Step 1: Choose the Right Investment Platform

To invest your $100, you’ll need a brokerage account that allows for:

  • No account minimums
  • Fractional shares
  • Low or no trading fees

Top beginner-friendly platforms:

  • Fidelity
  • Charles Schwab
  • Robinhood
  • Public
  • SoFi

All of these support fractional investing — meaning you can buy a slice of stock or ETF, even if it costs more than $100 per share.


Step 2: Pick Your First Investment

With only $100, you want to keep things simple and diversified.

Best options for beginners:

  • ETFs: Diversified, low-cost, easy to understand
  • Index Funds: Track the market (if using a retirement account)
  • Robo-advisors: Automated portfolios (e.g., SoFi, Betterment, Wealthfront)

Suggested starter ETFs:

  • VTI (Total U.S. Market)
  • VOO (S&P 500)
  • VXUS (International)
  • BND (Bonds)

You can buy a fractional share of any of these with your $100.


Step 3: Decide on Your Strategy

You don’t need to become a Wall Street expert. Choose one of these simple strategies:

Option 1: The One-ETF Approach

Invest your $100 in a diversified ETF like VTI and add more over time.

Option 2: 3-Fund Portfolio

Split your $100 into:

  • 60% U.S. Stocks (VTI)
  • 20% International (VXUS)
  • 20% Bonds (BND)

Option 3: Use a Robo-Advisor

Let a service like Betterment or SoFi Invest build and manage a portfolio for you. They use your risk profile to automate everything.


Step 4: Automate and Add More

Once your $100 is invested, the best thing you can do is make it a habit:

  • Automate contributions (even $25/month)
  • Reinvest dividends
  • Ignore short-term market noise

The more consistent you are, the more your money will grow.


What to Avoid When Starting Small

  • Trying to trade stocks — too risky and costly with small balances
  • Paying high fees — stick with low-fee ETFs or brokerages
  • Getting discouraged — $100 is a powerful start, not the end
  • Chasing hype — meme stocks and crypto fads aren’t great beginner options

Final Thoughts

Investing with just $100 isn’t just possible — it’s smart. It proves that you don’t need a big bank account to start building wealth.

Whether you choose ETFs, a robo-advisor, or a simple index fund, the most important step is to take action now.

Let that $100 be the first seed you plant on your path to financial independence.

Start small. Stay consistent. Grow big.
