Ready to put your idle cash to work? If you've been wondering how much Vanguard money market funds earn, you're in the right place! This comprehensive guide will walk you through everything you need to know about Vanguard's money market offerings, from understanding their yields to the nitty-gritty of choosing the right fund for your financial goals. Let's dive in!
Understanding Vanguard Money Market Funds: More Than Just a Savings Account
Vanguard money market funds are a popular choice for investors looking for a relatively safe and liquid place to park their cash while earning a competitive return. Unlike a traditional bank savings account, which is FDIC-insured, money market funds are mutual funds that invest in a portfolio of highly-rated, short-term debt securities. These typically include U.S. Treasury bills, commercial paper, certificates of deposit (CDs), and repurchase agreements.
The key characteristic of most retail money market funds, including Vanguard's, is their aim to maintain a stable Net Asset Value (NAV) of $1.00 per share. This means that while the interest you earn fluctuates, your principal investment generally remains constant.
How Do Vanguard Money Market Funds Earn Interest?
Vanguard money market funds earn interest by investing in these short-term debt instruments. The income generated from these investments, minus the fund's operating expenses (known as the expense ratio), is then distributed to shareholders. These distributions are typically paid out monthly and are often automatically reinvested back into the fund, allowing for the power of compounding.
The interest rate you see for a money market fund is usually expressed as a 7-day SEC Yield. This is a standardized calculation that provides an annualized yield based on the fund's average income distributions over the most recent seven-day period, after deducting expenses. It's a good measure for comparing the current earning potential of different money market funds.
Step 1: Discovering Current Vanguard Money Market Yields
So, the burning question: "How much does Vanguard money market earn right now?" This is where it gets a little dynamic, as yields change with the prevailing interest rate environment.
Sub-heading: Checking Real-Time Yields on Vanguard's Website
The most accurate and up-to-date information on Vanguard money market yields will always be directly on Vanguard's official website. You can typically find this information on their "Cash Investments" or "Money Market Funds" section.
As of late June 2025, here are some examples of Vanguard's money market funds and their approximate 7-day SEC yields:
Vanguard Federal Money Market Fund (VMFXX): Around 4.21% - 4.22%
Vanguard Cash Reserves Federal Money Market Fund Admiral Shares (VMRXX): Around 4.22%
Vanguard Treasury Money Market Fund (VUSXX): Around 4.21% - 4.23%
Vanguard Municipal Money Market Fund (VMSXX): Around 2.93% (This one offers tax-exempt income, which we'll discuss later!)
Important Note: These yields are as of June 2025 and are subject to change daily based on market conditions and the Federal Reserve's interest rate policies. Always check the latest figures on Vanguard's website before making any investment decisions.
Sub-heading: Understanding the 7-Day SEC Yield vs. APY
You might also hear the term "Annual Percentage Yield (APY)" when talking about savings accounts. While similar, the 7-day SEC Yield is specific to money market funds and aims to provide a comparable snapshot of their annualized income potential. It essentially projects what your annual return would be if the most recent seven-day performance continued for a full year.
Step 2: Factors Influencing Vanguard Money Market Earnings
Several factors determine how much Vanguard money market funds earn. Understanding these will help you anticipate potential changes in yields.
Sub-heading: The Federal Reserve and Interest Rates
The single biggest driver of money market fund yields is the Federal Reserve's monetary policy, specifically the federal funds rate. When the Fed raises interest rates, money market funds generally see their yields increase, and vice-versa. This is because the underlying securities they invest in, like Treasury bills, are directly influenced by these rates.
Sub-heading: Fund Expenses (Expense Ratio)
Every mutual fund has an expense ratio, which is the annual fee you pay as a percentage of your investment to cover the fund's operating costs. Vanguard is renowned for its low expense ratios, and their money market funds are no exception. A lower expense ratio means more of the gross earnings are passed on to you, the investor.
For instance, Vanguard Federal Money Market Fund (VMFXX) has a very low expense ratio, which contributes to its competitive yield. While Vanguard Prime Money Market Fund (VMMXX) used to exist, it has been closed, and its expense ratio was around 0.16% at the time of its closure.
Sub-heading: Type of Securities Held
Different Vanguard money market funds invest in different types of securities, which can affect their yields and risk profiles:
Government Money Market Funds (e.g., VMFXX, VUSXX): These funds primarily invest in U.S. government securities or repurchase agreements backed by such securities. They are generally considered the safest type of money market fund due to the implicit backing of the U.S. government. Their yields tend to be slightly lower than prime funds.
Prime Money Market Funds (e.g., VMMXX, now closed for retail investors): Historically, these funds invested in a broader range of high-quality, short-term debt, including corporate commercial paper and bank notes, in addition to government securities. They typically offered slightly higher yields than government money market funds due to taking on a small amount of additional credit risk. However, due to regulatory changes, Vanguard's Prime Money Market Fund (VMMXX) is no longer available to retail investors.
Municipal Money Market Funds (e.g., VMSXX): These funds invest in short-term municipal securities, the interest income from which is exempt from federal income taxes and often state and local taxes for residents of the issuing state. This tax-exempt status can make their after-tax yield very attractive, especially for investors in higher tax brackets, even if their gross yield appears lower than taxable money market funds.
Step 3: Investing in a Vanguard Money Market Fund – A Step-by-Step Guide
Ready to get started? Here's how you can typically invest in a Vanguard money market fund:
Sub-heading: Step 3.1: Open a Vanguard Account (If You Don't Have One)
If you're new to Vanguard, your first step is to open an account. This can be a:
Brokerage Account: This is the most common type of account and allows you to invest in a wide range of Vanguard mutual funds, ETFs, stocks, and bonds. Your money market fund will often serve as the settlement fund for this account, meaning your uninvested cash will automatically be swept into it.
IRA (Individual Retirement Account): If you're saving for retirement, you can open a Traditional IRA, Roth IRA, or SEP IRA. Money market funds can be a good option for the cash portion of your retirement portfolio.
Other Accounts: Vanguard also offers 529 plans for college savings, trust accounts, and more.
Actionable Tip: Visit Vanguard's website (vanguard.com) and look for the "Open an Account" or "Get Started" section. The process is typically straightforward and can be completed online.
Sub-heading: Step 3.2: Fund Your Account
Once your account is open, you'll need to deposit money into it. Common funding methods include:
Electronic Bank Transfer (ACH): This is usually the easiest and most common way to transfer funds from your bank account to your Vanguard account. It typically takes 1-3 business days for funds to clear.
Wire Transfer: For larger amounts or faster transfers, you can initiate a wire transfer from your bank.
Check Deposit: You can mail a check to Vanguard.
Transfer from Another Brokerage: If you have an existing investment account elsewhere, you can initiate a transfer of assets (ACATS transfer) to Vanguard.
Sub-heading: Step 3.3: Choose Your Vanguard Money Market Fund
While Vanguard Federal Money Market Fund (VMFXX) is often the default settlement fund for Vanguard brokerage accounts, you might want to actively invest in a specific money market fund based on your needs (e.g., a municipal money market fund for tax advantages).
Consider your goals: Are you looking for the highest possible taxable yield? Do you prioritize tax-exempt income?
Review expense ratios: While Vanguard's are generally low, it's always good to compare.
Check minimum investments: Most Vanguard money market funds have a minimum initial investment of $3,000.
Pro Tip: You can usually find a list of all available Vanguard money market funds and their details under the "Investment Products" or "Mutual Funds" section of their website.
Sub-heading: Step 3.4: Place Your Investment Order
Once your account is funded and you've chosen your fund, you can place your investment order.
Online: Log in to your Vanguard account, navigate to the "Trade" or "Invest" section, select the money market fund you want to buy, enter the amount, and confirm your purchase.
Phone: You can also call Vanguard's customer service to place an order.
For money market funds, you typically buy shares at a constant price of $1.00 per share. Your earnings will accumulate as additional shares or cash distributions, depending on your preference.
Step 4: Monitoring Your Earnings and Reinvesting
Once invested, it's important to understand how your earnings are calculated and distributed.
Sub-heading: Monthly Income Distributions
Vanguard money market funds typically pay out income distributions monthly. These distributions represent the interest earned by the fund's underlying securities, net of expenses.
Sub-heading: Automatic Reinvestment for Compounding
By default, Vanguard often sets up your money market fund to automatically reinvest these monthly distributions back into the fund. This is a powerful feature that allows your earnings to generate their own earnings, leading to compounding growth over time. You can usually change this preference in your account settings if you prefer to receive the distributions as cash.
Step 5: Tax Implications of Vanguard Money Market Funds
Understanding the tax treatment of your money market earnings is crucial for effective financial planning.
Sub-heading: Taxable Money Market Funds
For most Vanguard money market funds (like VMFXX and VUSXX), the interest income you earn is considered ordinary income for federal income tax purposes. This means it will be taxed at your regular income tax rate. It may also be subject to state and local income taxes. You'll receive a Form 1099-DIV from Vanguard summarizing your distributions for tax reporting.
Sub-heading: Tax-Exempt Municipal Money Market Funds
Vanguard offers municipal money market funds (e.g., VMSXX) that invest in debt issued by state and local governments. The interest earned from these funds is generally exempt from federal income tax. Furthermore, if you invest in a municipal money market fund from your state of residence, the income may also be exempt from state and local income taxes, providing a "triple tax-free" benefit.
Consideration: While municipal money market funds often have lower gross yields than taxable funds, their tax-exempt nature can make their after-tax return higher, especially for those in higher tax brackets. It's always wise to compare the after-tax yields to make an informed decision.

While considered very low risk, money market funds are not FDIC-insured like bank accounts. They aim to maintain a stable $1.00 NAV, but there's a theoretical, albeit historically rare, risk of "breaking the buck" (where the NAV falls below $1.00). Vanguard has a strong track record of supporting its money market funds.
