Fractional shares have revolutionized ETF investing by eliminating the barrier of high share prices. Instead of needing hundreds of dollars to buy a single share of a popular ETF, you can now invest any dollar amount — even just $1 — and own a proportional slice of the fund.
What Are Fractional ETF Shares?
A fractional share is a portion of a full share. If VOO trades at $500 per share and you invest $100, you receive 0.2 shares. You own exactly the same proportional exposure to the S&P 500 as a whole-share owner, earn proportional dividends, and benefit from the same price movements.
Fractional shares exist because your broker purchases whole shares and allocates portions to customers through an omnibus account. The fractional ownership is tracked internally by the broker rather than at the transfer agent level.
Which Brokers Offer Fractional ETF Shares
Most major brokers now support fractional ETF shares. Fidelity allows investments as low as $1 in most ETFs. Schwab supports fractional shares through its "Schwab Stock Slices" program with a $5 minimum. Interactive Brokers offers fractional shares on thousands of ETFs. Robinhood supports fractional shares with no minimum.
Broker Comparison
Fidelity and Schwab are the strongest choices for fractional ETF investing because they combine fractional share support with automatic investment plans. This means you can set up a $200 monthly purchase of VOO that automatically executes without manual intervention, which is ideal for dollar-cost averaging strategies.
How to Buy Fractional Shares Step by Step
Log into your brokerage account. Navigate to the trade ticket for your chosen ETF. Instead of entering a share quantity, look for the option to enter a dollar amount. Enter the amount you want to invest. Review and submit your order. The broker will purchase the equivalent fractional shares at the current market price.
Some brokers require you to toggle between "shares" and "dollars" on the order entry screen. If you do not see a dollar amount option, check the broker's settings or help documentation for fractional share trading.
Benefits of Fractional Shares
The most obvious benefit is accessibility — you can invest any amount regardless of share price. But fractional shares also enable precise portfolio allocation. If you want exactly 60% stocks and 40% bonds, fractional shares let you achieve that ratio exactly rather than rounding to the nearest whole share.
Fractional shares also make dollar-cost averaging more efficient. Every dollar gets invested immediately rather than accumulating as idle cash waiting until you can afford a whole share.
Limitations to Know
Fractional shares cannot be transferred between brokers. When you initiate an account transfer, whole shares move via ACAT, but fractional shares are sold and transferred as cash. This creates a small taxable event in taxable accounts. Some ETFs may not be eligible for fractional share trading at all brokers. Limit orders may work differently for fractional shares — some brokers only allow market or dollar-based orders.
Fractional Shares and Taxes
Fractional shares receive the same tax treatment as whole shares. Dividends are taxable, and selling creates a capital gain or loss. Your broker will track cost basis for fractional positions just like whole shares, and the information appears on your year-end 1099 form. There is no special tax complexity from owning fractional shares.
Getting Started
If your broker supports fractional shares, there is no reason not to use them. Start by investing your target amount in a diversified core ETF. Set up automatic recurring investments. As your portfolio grows, add additional ETFs for diversification. Visit our education center for guidance on building a complete ETF portfolio with any budget.
