How to Start Investing With Only $100 in 2025
Think you need thousands of dollars to start investing? Think again. In 2025, the barrier to entry is lower than ever. Thanks to fractional shares and commission-free trading, you can genuinely start your wealth-building journey in the USA with just **$100**. This guide breaks down the most effective, beginner-friendly strategies to turn that initial C-Note into a growing portfolio.
Step 1: Choose Your Platform Wisely
The first crucial step is selecting the right brokerage. For small amounts, you need a platform that supports fractional shares and charges **zero commission** for stock and ETF trades. Look for popular, reliable US-based apps like Fidelity, Charles Schwab, or Robinhood. They allow you to buy *parts* of expensive stocks, ensuring your whole $100 is put to work immediately.
Pro Tip: Before depositing, check if the platform offers a signup bonus or free stock just for opening an account. Every extra dollar counts when you’re starting small! (Read our full comparison: [Internal Link: Best Brokerages for Beginner Investors])
Step 2: Diversify with ETFs (Exchange-Traded Funds)
Putting all $100 into a single stock is risky. **Diversification** is key. The best way to achieve this with minimal funds is through Exchange-Traded Funds (ETFs). An ETF is a basket of hundreds or even thousands of stocks (like the S&P 500) traded as a single share.
- **S&P 500 ETFs (e.g., VOO, IVV):** This is the gold standard. It gives you immediate exposure to the 500 largest US companies. A fractional share here is a solid, long-term move.
- **Total Stock Market ETFs (e.g., VTI):** Broader than the S&P 500, covering nearly the entire US stock market. Excellent for maximum diversification.
- **Specific Sector ETFs (e.g., Tech, Green Energy):** If you're confident in a growing industry, a sector ETF can provide focused exposure without the single-stock risk.
Step 3: Consider Micro-Investing and Robo-Advisors
If you prefer a totally hands-off approach, micro-investing apps or robo-advisors are fantastic starting points. Apps like Acorns automatically round up your purchases and invest the difference, making your small contributions automatic.
Robo-advisors (available through platforms like Betterment or Schwab Intelligent Portfolios) will create and manage a diversified portfolio for you based on your risk tolerance, often for a very low fee or free for smaller balances. This minimizes emotion and maximizes systematic growth.
Step 4: Explore High-Yield Savings Accounts (HYSA)
While not strictly "investing," if your financial goal is near-term (within 1-2 years) or you are still building an emergency fund, a **High-Yield Savings Account (HYSA)** is a must. Many online banks offer competitive Annual Percentage Yields (APYs) well above the national average. Your $100 is safe (FDIC-insured) and earns interest instantly. This is a critical foundation before tackling riskier assets.
The Power of Consistency Over Capital
Remember, the goal is not to get rich overnight with $100. The goal is to build the **habit of investing**.
