With high interest rates continuing in 2025, many investors are moving idle cash into money market funds to earn safe, reliable returns. One of the most popular choices? The Vanguard Treasury Money Market Fund, known by its ticker VUSXX.
This guide breaks down everything you need to know about the VUSXX interest rate, how and when it pays interest, and why it could be a smarter move than a high-yield savings account in today’s market.
What Is the VUSXX Interest Rate?
The VUSXX interest rate refers to the 7-day SEC yield of the Vanguard Treasury Money Market Fund. This yield represents the annualized return the fund has paid over the last 7 days, after fees.
Current VUSXX Yield (May 2025):
- 7-Day SEC Yield: 4.87%
- Expense Ratio: 0.09%
- NAV (Net Asset Value): $1.00 (stable)
- Dividend Frequency: Monthly
- Tax Treatment: State tax-exempt (federal taxes apply)

Unlike a bank account APY, the SEC yield standardizes performance across money market funds, giving you a real apples-to-apples yield comparison.
How Often Does VUSXX Pay Interest?
VUSXX pays interest monthly in the form of a dividend distribution. Here’s how it works:
- Interest accrues daily
- Payouts occur on the last business day of each month
- Dividends can be reinvested or transferred to a linked account
So, how often does VUSXX pay interest?
- Once per month
- Typically paid on the last business day
When Does VUSXX Pay Interest?
You receive your interest payout (dividend) monthly, usually on the final business day of each month. Here’s a sample:
| Month | VUSXX Interest Payment Date |
|---|---|
| April 2025 | April 30 |
| May 2025 | May 30 |
| June 2025 | June 30 |
You’ll see the dividend either:
- Reinvested into more shares of VUSXX
- Deposited into your linked bank or brokerage account (if elected)
You can check distribution history under the “Dividends” section of Vanguard’s performance page.
Why Is the VUSXX Interest Rate So Attractive in 2025?
The Federal Reserve’s higher-for-longer rate stance has kept short-term Treasury yields elevated. Because VUSXX invests exclusively in U.S. Treasury bills and repurchase agreements, it benefits directly from these higher short-term yields.
As a result:
- It remains competitive—even outpacing many high-yield savings accounts
Is VUSXX Interest Compounded?
Yes—but with a unique structure.
- Interest is accrued daily based on the number of shares you hold.
- The dividend is paid monthly and can be automatically reinvested, which allows for compounding over time.
Unlike a savings account, your balance doesn’t grow daily—it grows when new shares are added through reinvestment.

What Impacts the VUSXX Interest Rate?
Several key factors influence the interest rate (yield) you’ll earn:
1. Federal Reserve Policy
VUSXX tracks short-term Treasury yields, which move in line with the Fed’s rate decisions. If the Fed raises or cuts rates, VUSXX’s yield typically follows.
2. U.S. Treasury Bill Rates
Since the fund invests in 3-month or shorter Treasuries, these rates directly affect the income VUSXX generates.
3. Fund Expenses
Vanguard’s ultra-low expense ratio (0.09%) allows more interest to be passed on to investors.
Is VUSXX Interest Taxed?
Federal Taxes:
- Interest income from VUSXX is fully taxable at the federal level.
State Taxes:
- Because VUSXX holds 100% U.S. Treasuries, the interest is exempt from most state income taxes.
This makes VUSXX a tax-efficient choice for high-income investors in states like California, New York, or Oregon.
How to Maximize Your VUSXX Earnings
Even though it’s not a high-growth investment, here’s how to make the most of VUSXX:
- 1. Reinvest Dividends
Enable automatic reinvestment to benefit from compounding.
- 2. Hold in Tax-Advantaged Accounts
If you’re concerned about federal taxes, hold VUSXX inside an IRA or tax-deferred brokerage account.
- 3. Use for Cash Reserves

Who Should Use VUSXX?
VUSXX is best for:
- Conservative investors seeking capital preservation
- Retirees needing income with low volatility
- Brokerage account holders wanting to earn yield on idle funds
