Our Methodology

To find the best money market mutual funds available, we started with data from the Office of Financial Research. We reviewed the top money market fund providers (by market capitalization) and found the funds with the highest 1-year yields and reasonable expense ratios.

We focused mainly on money market funds with substantial assets under management, as this helps to ensure liquidity and security should there be turmoil in the market. Most of the funds chosen have more than $100 billion in assets. We also avoided funds with high minimum investments—capping it at $3,000.

How to select the best money market fund

The best money market funds offer high yields, low expense ratios, and reasonable minimum investments for individual investors. Consider the following when conducting your own research to find a money market fund:

Find a reputable brokerage firm or fund manager

Your search for a quality money market fund should start by researching reputable brokers and fund managers, such as those on our list. It’s important only to use a financial institution you can trust.

You can use FINRA’s BrokerCheck tool to research the backgrounds and credentials of brokers and investment advisers.

Compare yields and expense ratios

Finding money market funds with competitive yields and low expense ratios will help you earn more interest. While some money market funds offer eye-popping returns, they may charge higher fees, lowering overall returns.

Pick one with a minimum deposit you can afford

Money market funds typically have a minimum deposit requirement. While some offer $1 minimum deposits, some require up to $1,000 or more. Pick a fund with an affordable minimum so you can begin earning interest right away.

Alternatives to money market funds

Money market funds offer a low-risk way to earn interest on your cash, but they aren’t the only way. The following money market fund alternatives offer high yields:

High-yield savings accounts

High-yield savings accounts offer high yields on cash deposits and are covered by FDIC insurance, which is not the case with money market funds.

Money market accounts

Money market accounts also offer attractive deposit rates and may allow you to write checks or withdraw cash from ATMs. They are more liquid than money market funds, making money more accessible.

U.S. Treasury bills (T-Bills)

U.S. Treasury bills (T-Bills) are government debt fixed income securities that offer high yields when purchased and held to maturity. You can purchase T-Bills for four, eight, 13, 17, 26, and 52 weeks. Yields are on par with those of money market funds.

Certificates of deposit (CDs)

Certificates of deposit, or CDs, are timed deposit accounts that pay interest for locking up your funds for a specific duration. Terms typically range from one month to several years, with rates dependent on the term you choose. Putting your cash in CDs makes it less accessible than in money market funds, as you’ll usually pay a penalty for withdrawing money before maturity.

Money market fund vs. savings account

Money market funds are a type of mutual fund, while savings accounts are deposit accounts. Money market funds require purchasing shares of a mutual fund and can require a minimum investment. They are not FDIC-insured.

Most bank savings accounts are FDIC-insured, don’t have minimum deposit requirements (some do), and pay interest on cash deposits. You can withdraw money from a savings account at any time. To access your cash in a money market fund, you’ll have to sell shares of the fund and wait for the transaction to settle.

Money market fund vs. money market account

Both money market funds and money market accounts pay interest. However, money market funds are a type of mutual fund investment, while money market accounts are a type of deposit account. Money market funds require you to purchase shares of the fund, and money market accounts, on the other hand, are more similar to savings accounts.

More on money market funds

What is a money market mutual fund?

A money market mutual fund is a type of mutual fund that invests in low-risk securities, such as cash, cash equivalents, and short-term debt securities. These funds are designed to offer a steady yield while avoiding the volatility and risk of the stock market.

Money market mutual funds are available through most major brokerage and fund management firms and may even be your default position in your cash account through your investment platform. And while there is very little risk of loss with these funds, in very volatile markets, there is a chance that the fund price could drop below $1 per share.

How does a money market fund work?

Money market funds are a type of mutual fund in which investors purchase shares. They are designed to trade at $1 per share while holding low-risk securities such as U.S. Treasuries, CDs, cash, and other debt securities.

Income earned from the underlying investments helps inform the interest rate paid on money market funds, which can fluctuate daily. The Federal Funds rate ultimately affects the performance of the underlying investments, so if the Federal Reserve decides to lower rates, the yield of the money market fund may drop as well.

Money market funds pros and cons

Money market funds are a secure place to park cash and earn a competitive yield. Here are a few pros and cons to consider.

Types of Money Market Funds

There are several types of money market funds, each with a different investment approach and tax treatment:

Government money market funds

Government money market funds invest primarily in U.S. Treasuries and other government-backed debt securities. Some of the income generated from government money market funds is exempt from state and local taxes, depending on the underlying investments.

Prime money market funds

Prime money market funds invest in low-risk corporate debt securities, such as commercial paper and other non-Treasury assets. Income from these funds is fully taxable at the federal, state, and local levels.

Municipal money market funds

Municipal money market funds invest in tax-exempt bonds and other debt securities. The income from these funds is exempt from federal income tax and sometimes state and local taxes too. The yield tends to be slightly lower than traditional money market funds, but the tax savings may be worth it to some investors.

How are money market funds performing today?

Since the Federal Reserve consistently raised rates throughout 2022 and 2023, money market funds have begun to offer more attractive yields. As of March 2024, many money market funds have returned 1-year yields of over 5%.

While yields are currently high, the future of money market fund rates is unknown. Should inflation continue lowering to the Federal Reserve’s expected 2% rate, it may choose to lower the Federal Funds rate. This, in turn, may lower the yields on money market funds in the future. As with any mutual fund, money market returns are not guaranteed, and past performance is not an indicator of future returns.

How to find money market mutual funds

Money market funds are available through various financial institutions, such as most major brokerage firms, fund companies, and banks. The Office of Financial Research mutual fund search tool allows you to view a list of the largest money market funds by market capitalization.

It’s important to review a money market fund’s total asset amount, expense ratio, and seven-day yield to gauge its potential performance.

TIME Stamp: Earn more interest with less risk

Money market funds are ideal for parking cash and earning interest with little risk. The best money market funds offer a balance between a high yield and low expense ratio, allowing you to keep more of the interest earned. And while some risk is involved, money market funds are among the lowest-risk investments available.

Frequently asked questions (FAQs)

What are the typical fees and charges associated with money market funds?

Money market funds are typically actively managed, meaning a team chooses investments that the fund holds. The fees associated with fund management and operation are known as the “expense ratio.” There may also be trading fees and 12b-1 fees for market and distribution. Some funds charge a liquidity fee as well.

How are the yields on money market funds calculated?

Yields for money market funds are calculated based on the maturity of the underlying investments and a 360-day bank year. The yield is the holding period yield multiplied by 360, divided by the number of days until maturity.

For example, if you purchase a money market fund for $1,000 and the holding period yield is $5 with 50 days until maturity, then the overall yield is 3.6% APY. When looking for money market fund yield, always look for the seven day yield for the best gauge of current yields.

What are the tax implications of investing in money market funds?

There are different tax implications based on the type of money market fund you invest in, the holding period, and what type of account you use to buy and sell money market funds. For example, if you own money market funds within your individual retirement account (IRA), then there are no taxes assessed until you withdraw funds in retirement. But if you purchase a government money market fund within your taxable brokerage account, you will owe federal taxes on interest earned. It’s a good idea to meet with a licensed tax professional before investing in a money market fund or any investment if you’re worried about the tax implications.
