How to Buy Mutual Funds in Fractions


Investing in mutual funds has long been a cornerstone strategy for both beginner and experienced investors. Mutual funds offer diversification, professional management, and access to a broad range of securities that would be difficult to manage individually. 

Traditionally, investors purchased mutual funds in whole shares, which could be limiting for those with smaller budgets or those looking to invest specific dollar amounts. Today, the landscape has changed, and buying mutual funds in fractions—or fractional shares—has become increasingly accessible.

What Are Fractional Mutual Fund Shares?

Fractional shares are portions of a full mutual fund unit. Instead of buying one full share, investors can purchase a fraction, such as 0.5 or 0.25 of a share. Fractional investing allows for precise allocation of funds based on the exact dollar amount an investor wishes to contribute.

For example, if a mutual fund has a share price of $200 and you want to invest $50, you could buy 0.25 shares instead of waiting to accumulate enough funds to purchase a full share.

This approach is particularly beneficial for those who:

  • Are investing with limited capital
  • Want to implement dollar-cost averaging strategies
  • Aim to invest a specific percentage of their portfolio in a particular fund

Why Fractional Mutual Fund Investing Is Gaining Popularity

Fractional investing is reshaping how investors approach mutual funds for several reasons:

  • Accessibility: Previously, minimum investment requirements for mutual funds could range from $500 to $3,000 or more. Fractional investing eliminates this barrier, allowing investors to start with virtually any amount.
  • Diversification: Fractional shares enable investors to diversify across multiple funds even with smaller budgets, reducing portfolio risk.
  • Dollar-Cost Averaging: Investors can contribute fixed dollar amounts periodically, regardless of the share price, which smooths out market volatility over time.
  • Flexibility: You can invest precise amounts in multiple funds without being restricted by the price of a whole share.

According to a 2024 report by Morningstar, mutual fund platforms offering fractional investing have seen a 35% increase in participation from new investors under 35, demonstrating the appeal of this approach to younger, budget-conscious investors.

How Fractional Mutual Funds Work

When you purchase fractional shares, you are still entitled to all the benefits of mutual fund ownership. These include:

  • Proportional dividends and interest: Any distributions are calculated based on the fraction of the share you own. For example, if the fund pays a $10 dividend per full share and you own 0.5 shares, you would receive $5.
  • Proportional gains or losses: Any change in the fund’s net asset value (NAV) affects your investment proportionally.
  • Voting rights: Some mutual funds allow investors to vote on corporate matters; your voting power is proportional to the number of shares you own.

Fractional investing is facilitated by modern brokerage and fund platforms that can track portions of shares for each investor, ensuring accurate accounting and distributions.

Platforms That Offer Fractional Mutual Fund Investing

Not all brokerages or mutual fund platforms support fractional mutual fund investing. Some of the most widely used platforms include:

  • Fidelity: Fidelity allows fractional investing in thousands of mutual funds through its Digital Assets platform. Investors can purchase any dollar amount starting from $1.
  • Charles Schwab: Schwab offers fractional share investing for mutual funds and ETFs, enabling investors to diversify with small contributions.
  • Vanguard: While Vanguard is traditionally known for requiring full shares, its brokerage account now supports fractional purchases in many funds, particularly ETFs.
  • M1 Finance: This platform specializes in fractional share investing, including mutual funds and ETFs, with automatic reinvestment of dividends.
  • Betterment & Wealthfront: Robo-advisors like these allow fractional mutual fund investments in pre-allocated portfolios, making it easy for beginners to implement a diversified strategy.

Expert Tip: Before selecting a platform, review any account fees, minimums, and whether fractional investing is available for the specific mutual fund you want.

Steps to Buying Fractional Mutual Funds

Buying fractional mutual funds follows a similar process to purchasing full shares, but with additional flexibility regarding the amount you invest.

1. Open a Brokerage or Fund Account

Start by selecting a brokerage or mutual fund provider that supports fractional investing. Complete the account registration, providing personal information, tax ID, and funding details.

2. Fund Your Account

Deposit the amount you intend to invest. With fractional investing, you can start with as little as $1 on some platforms, though $50–$100 is common for practical diversification.

3. Select Your Mutual Fund

Identify the mutual fund you want to invest in. Consider factors like:

  • Fund Type: Equity, bond, hybrid, or index
  • Expense Ratio: The annual management fee expressed as a percentage of assets
  • Historical Performance: Though past performance is not indicative of future results, it provides context
  • Investment Strategy: Growth, value, income, or balanced

4. Specify the Investment Amount

Instead of entering the number of shares, enter the dollar amount you wish to invest. The platform will automatically calculate the fraction of a share you are purchasing based on the current NAV.

5. Confirm the Transaction

Review your order details and confirm the purchase. The fractional share will now be part of your account, and you can track it alongside your other investments.

Dollar-Cost Averaging with Fractional Mutual Funds

One of the most powerful strategies enabled by fractional investing is dollar-cost averaging (DCA). DCA involves investing a fixed dollar amount at regular intervals, regardless of the fund’s share price.

For example, you could invest $100 in a mutual fund every month. Some months, $100 might buy 0.8 shares, and other months it could buy 1.2 shares, depending on the NAV. Over time, this approach averages out the cost per share and reduces the risk of investing a lump sum at the wrong time.

Expert Insight: According to financial advisor Michael Kitces, DCA can be especially useful for beginner investors, as it mitigates emotional reactions to market volatility and promotes consistent investment behavior.

Reinvesting Dividends in Fractions

Most mutual funds pay dividends or interest to investors. Fractional investing allows these payments to be automatically reinvested, buying additional fractions of a share.

For instance:

  • You own 0.5 shares of a fund paying $10 per full share in dividends.
  • You receive $5 in dividends.
  • The platform automatically reinvests the $5, buying additional fractional shares based on the current NAV.

This automatic reinvestment accelerates the compounding of your investments, a key driver of long-term wealth growth.

Risks and Considerations of Fractional Mutual Fund Investing

While fractional investing offers significant advantages, it is important to understand the potential risks and limitations:

  • Platform Limitations: Not all brokerages support fractional mutual fund investing. Some funds may be restricted.
  • Liquidity: Selling fractional shares is generally straightforward, but some platforms may impose processing delays.
  • Expense Ratios: High-fee funds can erode returns over time. Fractional investing does not eliminate fees.
  • Market Risk: Fractional shares are still subject to market fluctuations. Diversification can reduce risk but not eliminate it.
  • Tax Reporting: Fractional dividends and capital gains are fully taxable and reported to the IRS. Investors should ensure the platform provides accurate reporting.

Pro Tip: Diversify across multiple funds and asset classes to mitigate risk, even when investing fractional amounts.

Case Study: Fractional Investing in Action

Consider Jane, a new investor with a budget of $500. She wants exposure to three mutual funds:

  • Fund A: $250 per share
  • Fund B: $100 per share
  • Fund C: $75 per share

Without fractional investing, Jane could only afford Fund B and Fund C fully. However, with fractional shares, she can allocate her $500 as follows:

  • Fund A: $200 → 0.8 shares
  • Fund B: $150 → 1.5 shares
  • Fund C: $150 → 2 shares

Jane now has exposure to all three funds, achieving better diversification and optimizing her investment allocation.

Tips for Successful Fractional Mutual Fund Investing

  2. Automate Contributions: Set up automatic monthly or weekly investments to benefit from dollar-cost averaging.
  3. Track Fees: Even small fees can add up. Choose low-cost funds to maximize returns.
  4. Diversify: Use fractional shares to diversify across sectors, asset classes, and fund styles.
  5. Reinvest Dividends: Enable automatic reinvestment to take advantage of compounding.
  6. Monitor Performance: Periodically review fund performance, allocation, and portfolio balance.
