*The annualized yield for a Treasury Bill (“T-Bill”) maturing in one month as of 1/6/2025 when held to maturity is 4.30%. Rate shown is gross of fees. Annual percentage yield (APY) is the nominal interest rate of the T-Bill maturing in one month with 12 compounding periods per year. Annualized yield and APY are investment characteristics of the T-bill and should not be regarded as performance or a projection of performance of any Treasury account. The effective return on T-Bills will be reduced by fees which has a compounding impact on returns over time.

Estimated returns are shown gross of fees. Calculator assumes highest income rate per state (Source: Federation of Tax Administrators). Savings may be less if a lower income rate applies. High-yield savings rate defaults to average of the best high-yield savings accounts, compiled by NerdWallet.com. NerdWallet does not provide investment, tax or legal advice. You should consult your legal, tax, or financial advisors before making any financial decisions. Results may vary with each use and over time. IMPORTANT: The projections or other information generated by this analysis tool regarding the likelihood of various investment outcomes are hypothetical in nature, do not reflect actual investment results and are not guarantees of future results. The calculation for annual interest earned assumes a constant 4 week Treasury yield throughout the year. To estimate annual interest, the 4 week interest earned is multiplied by 13, since there are approximately 13 4 week periods in a year. Please note that actual Treasury yields may fluctuate, and this assumption may not reflect real market conditions.

All about Treasury Bills

What are they?
T-Bills are short-term debt securities issued by the U.S. Government. They’re typically sold in increments of $100 and mature in less than a year.

How do I earn money?
Once you’ve deposited money into your Atomic Treasury account, T-Bills are purchased for you at a discount and are held to maturity (unless you withdraw money early). Your earnings and principal are automatically reinvested into new T-Bills of the same term.

Why trust them?
Because T-Bills are backed by the full faith and credit of the U.S. Government, they’re nearly risk-free if held for the entire term.

What returns could I get?
It varies, but for example — a $1,000 T-Bill may cost $996.41 to purchase, generating an income of $3.59 over a 4-week period. This equates to 4.68% annualized yield.†

NERDY TIP 🤓

Consider using a Treasury account for money that you might need soon — like a down payment on a house. A high-yield savings account may be a smart place to store money that you might need now, like an emergency fund.

The Atomic Treasury account is an investment advisory account offered through our partnership with Atomic Invest LLC (Atomic Invest) and is available at exclusive fees to NerdWallet+ members. The Atomic Treasury account offers customers a competitive APY of up to % through the purchase and reinvestment of 4-week Treasury Bills (T-Bills). Key benefits include:

• High yield: Earn up to % APY on T-Bills through a Treasury account, which can be more attractive than high-yield and regular savings accounts.
• Tax advantages: Earned interest is exempt from state and local income taxes — which can make the Atomic Treasury account more attractive for customers in states with high tax burdens, like New York and California.
• Daily liquidity: Access your funds any time with no restrictions on withdrawals.³ However, to capture the full yield, you’ll need to allow your T-Bills to mature — this generally takes up to 4 weeks.
• Security: T-Bills are a low-risk investment backed by the full faith and credit of the U.S. Government.
• No minimums: The Atomic Treasury account has no minimum deposit or balance requirements.
• Automatic management: Once funds are deposited into the Atomic Treasury account, they are automatically used to purchase your Treasury Bills. As your Treasury Bills mature, their interest and your principal are re-invested in new T-Bills of the same term — so your money is working hard for you with minimal effort.

Once you open and fund your Atomic Treasury account through Atomic Invest, Atomic Invest will automatically invest funds in high-yielding 4-week T-Bills to maximize returns.

Treasury Bills (T-Bills) are short-term U.S. debt securities issued by the federal government that mature in less than a year. Common maturities are 4 weeks, 8 weeks, 13 weeks, 26 weeks, and 52 weeks. The Treasury account available to NerdWallet+ members invests in T-Bills that mature within 4 weeks.

T-Bills are typically purchased in increments of $100 par value — the T-Bill’s value at maturity. T-Bills are purchased at a discount, and the difference between the discounted price and the par value is your yield. For example — a $1,000 T-Bill may cost $996.41 to purchase, generating an income of $3.59 over a 4-week period. This equates to 4.68% annualized yield.† T-Bills generally rise in value and approach par value as the maturity date nears.

When your T-Bills mature, the principal and earned interest are automatically reinvested by Atomic Invest in a new T-Bill of the same term.

For providing its investment services, Atomic Invest charges 0.25%⁴ annually. NerdWallet+ members unlock a lower fee of 0.18% annually. This amount will be deducted from your Atomic Treasury account on a monthly basis. Learn about NerdWallet+.

Treasury Bill (“T-Bill”) yields may vary based on dates of issuance and maturity. The value of T-Bills fluctuates and you may receive more or less than your original investment if sold prior to maturity. T-Bills are purchased at a discount to par, with the price being subject to market fluctuation. The amount of T-Bills available at a particular yield will depend upon the sellers’ offer size; any remaining cash balance after the purchase may not earn the same yield. In general, the bond market is volatile, and fixed income securities carry interest rate risk. Fixed income securities are subject to increased loss of principal during periods of rising interest rates. Fixed income securities also carry other risks, including inflation risk, liquidity risk, call risk, and credit and default risks for both issuers and counterparties. Income earned on Treasuries is exempt from state and local taxes, but taxable by the federal government.

The Atomic Treasury account is a managed account that seeks safe, low-risk returns on your investment by investing in short-term T-Bills. Before investing, you should consider whether the strategy is consistent with your overall financial situation, risk tolerance and goals.

⁵Access to your funds is typically available at any time. Transactions will be monitored and may be held, delayed or blocked if the transfer could result in fraud or another form of financial harm. Additionally, sometimes transfers can be delayed.

⁶How Fees are Collected: The annual investment advisory fee of 18 basis points (or 0.18%) for NerdWallet+ members and 25 basis points (or 0.25%) will be accrued daily and collected monthly in arrears or, if you terminate your account before a month-end, the investment advisory fee will be prorated through the Account termination date. Investment advisory fees will also be prorated based on additions or withdrawals to the Account during the applicable billing period. Investment advisory fees will be based on the market value of the securities as determined by Atomic Invest, including any cash in your account at the end of each business day, as of the close of trading on the New York Stock Exchange (“NYSE”) or as of the immediately preceding close of the NYSE for days when the NYSE is closed. Any cash balance in your account will be held in a money market fund.

An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although a money market fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in a money market fund. Yields fluctuate and past performance is no guarantee of future results. The investment objectives, risks, charges, expenses and other information about the money market fund are found in the fund’s prospectus.

^†The value of T-Bills fluctuate and you may receive more or less than your original investment if sold prior to maturity. T-bills are subject to price change, yield change and availability. Although T-bills are considered safer than many other financial instruments, you could lose all or a part of your investment. T-Bills carry a variety of risks, including credit risk, interest rate risk, and liquidity risk. Income earned on Treasuries is exempt from state and local taxes, but taxable by the federal government.
