Starting your investment journey does not require thousands of dollars. In fact, learning how to invest $100 on Fidelity can help you build a diversified portfolio and establish good habits from the very beginning. Thanks to fractional shares and low-cost index funds, even a small amount can provide exposure to thousands of companies.
Fidelity offers several beginner-friendly options, making it easy to start investing without worrying about large account balances or expensive fees.
Why $100 on Fidelity Is Enough to Start Investing
Many new investors delay getting started because they think they need a lot of money. The reality is that $100 on Fidelity is enough to build a real portfolio. With fractional shares, you can invest any amount, even as little as $1, and Fidelity’s low-cost funds help maximize every dollar.
Another advantage is the availability of Fidelity Zero funds, which carry no expense ratio. These funds allow investors to keep more of their returns over time.
What Makes Fidelity Attractive for Beginners?
Fidelity provides two major benefits:
- Fractional shares that allow investments in dollar amounts instead of full shares.
- Low-cost index funds with extremely low expense ratios.
- Zero expense ratio funds exclusive to Fidelity.
- No minimum investment requirements for many mutual funds.
- Commission-free trading.
These features make investing $100 on Fidelity simple and accessible.
Best Funds to Buy as a Beginner
FXAIX: Fidelity 500 Index Fund
FXAIX tracks the S&P 500, giving investors exposure to some of America’s largest companies, including Apple, Microsoft, Nvidia, Amazon, and Alphabet.
Benefits include:
- Expense ratio of only 0.015%
- Exposure to 500 major companies
- Long-term average returns near 10% annually
- No minimum investment requirement
FXAIX serves as a strong foundation for almost any portfolio.
FSKAX: Fidelity Total Market Index Fund
FSKAX expands your exposure beyond the S&P 500 by including thousands of large, medium, and small-cap companies.
Advantages include:
- Broad exposure across the entire U.S. market
- Same low expense ratio as FXAIX
- Access to future growth companies before they become industry giants
Although there is overlap with FXAIX, some investors choose to hold both for additional diversification.

FDVV: Fidelity High Dividend ETF
FDVV focuses on established companies that consistently pay dividends.
This fund offers:
- Quarterly dividend income
- Exposure to high-quality companies
- Additional stability within a portfolio
Dividend investing can become increasingly important as investors approach retirement.
FTIHX: Fidelity Total International Index Fund
International diversification helps reduce dependence on the U.S. market.
FTIHX provides exposure to:
- European markets
- Japanese companies
- Emerging economies
- Thousands of businesses outside the United States
Many investors allocate only 5% to 10% of their portfolio internationally while maintaining a heavier focus on U.S. investments.
Fidelity Zero Funds
One feature unique to Fidelity is its lineup of zero-expense-ratio funds:
- FZROX: Zero-cost version of the total U.S. market.
- FNILX: Zero-cost version of the large-cap index.
- FZILX: Zero-cost international fund.
These funds are especially attractive inside Roth IRAs and retirement accounts. However, since they are exclusive to Fidelity, transferring to another brokerage later would require selling them first.
How to Split $100 on Fidelity
The ideal allocation depends partly on age and investment goals.
A simple approach uses age as the percentage allocated toward dividend-focused investments.
Example for a 30-Year-Old
- 30% in dividend investments
- 35% in FSKAX
- 35% in FXAIX
Example for a 25-Year-Old
- 25% in dividend investments
- 75% divided between FXAIX and FSKAX
Example for a 50-Year-Old
- 50% in dividend investments
- 50% divided between the two growth funds
This approach balances growth and income based on life stage.

How to Buy Your First Investment on Fidelity
Purchasing investments on Fidelity is straightforward.
Step 1: Open the Trade Screen
Tap the “Transact” button or use the search icon.
Step 2: Enter the Ticker Symbol
Examples include:
- FXAIX
- FSKAX
- FDVV
- VTI
The ticker symbol is simply a short code representing a fund or stock.
Step 3: Choose Dollar Amount Instead of Shares
One of Fidelity’s biggest advantages is allowing investors to enter a dollar amount rather than calculating shares manually.
For example, you can purchase:
- $5 worth of VTI
- $20 of FXAIX
- $35 of FSKAX
Fractional shares make investing accessible to everyone.
Step 4: Select Market Order
Beginners typically use market orders, which purchase investments at the current market price.
Step 5: Review and Confirm
Fidelity displays:
- The ticker symbol
- Dollar amount
- Estimated shares
- Total cost
After reviewing everything, submit the order.
Within minutes, your investment is complete.
Sample Portfolio for $100 on Fidelity
A simple portfolio could look like:
| Investment | Allocation |
|---|---|
| FXAIX | $35 |
| FSKAX | $35 |
| FDVV | $30 |
This provides exposure to thousands of American companies while adding a source of dividend income.
Why Simplicity Wins
Many investors make the mistake of owning 10 or 15 funds that overlap heavily. In reality, three or four funds are often enough.
Keeping things simple can provide:
- Broad diversification
- Lower fees
- Easier portfolio management
- Less emotional decision-making
Consistency matters far more than complexity.
Building Wealth One Contribution at a Time
Learning how to invest $100 on Fidelity is not about becoming rich overnight. It is about creating a habit that compounds over decades. The first $100 matters because it establishes the foundation. The second $100 builds upon the first, and every contribution after that continues the process.
Starting with $100 on Fidelity today can be far more valuable than waiting years until you feel ready. Small amounts invested consistently can grow into substantial wealth over time.
