How to Start Investing with Just $100 in 2025: Beginner’s Guide

Starting your investment journey doesn’t require thousands of dollars. In fact, in 2025, you can start investing with just $100—and thanks to modern platforms, it’s easier than ever. Here’s how you can make your first $100 investment work for you.


💡 1. Choose a Low-Cost Brokerage

To start investing, choose a beginner-friendly platform that offers:

  • No commission fees on trades
  • Low or no minimum deposit requirements
  • Fractional shares, so you can buy partial shares of expensive stocks like Amazon or Tesla

Popular options include:

  • Robinhood – Offers commission-free trades with a simple interface.
  • Webull – A more advanced option with commission-free trades and great analysis tools.
  • SoFi Invest – Offers no account minimums and is very beginner-friendly.
  • Fidelity – Known for its reliable and low-fee investment options, also offers fractional shares.

📊 2. Invest in ETFs or Index Funds

Instead of investing in just one stock, diversify your $100 into ETFs (Exchange-Traded Funds) or Index Funds. These funds invest in multiple companies, helping you spread out risk.

Some of the most popular low-cost ETFs include:

ETFs are generally safer than picking individual stocks and are great for long-term growth.


🪙 3. Consider Fractional Shares

Don’t let high stock prices hold you back. Platforms like Fidelity, M1 Finance, and Robinhood allow you to buy fractional shares, meaning you can invest just $1 in high-priced stocks like Apple, Google, or Tesla.

For example:

  • If Apple stock is priced at $150 per share, you could buy 0.67 of a share with just $100.

This allows your $100 to be spread across multiple companies, even if the individual stock prices are high.


📈 4. Set Up Automatic Contributions

The key to building wealth is consistency. Many platforms allow you to automate weekly or monthly contributions. Even adding $25 a month can make a big difference, thanks to compound interest.

By regularly contributing small amounts, you can slowly grow your investment without having to think about it.


💸 5. Avoid High Fees & Stay Consistent

Keep an eye on fees—especially if you’re using apps with subscription models or hidden charges. Stick with low-fee ETFs or brokerages with transparent pricing to make the most of your $100.

And most importantly: don’t try to time the market. Time in the market beats trying to time the market, especially when you’re just starting out. Consistency and patience are key.


✅ Final Thoughts

Investing $100 might seem small, but it’s the most important step you’ll take. With the right strategy and consistency, that $100 can be the beginning of long-term financial growth. Remember: it’s not about how much you start with—it’s about starting at all.

Start simple, stay consistent, and watch your money grow over time. Your future self will thank you for it!
