How to Buy Treasury Bills: A Complete Guide to Safe Investing
Investing in Treasury bills (T-bills) is a popular choice for those seeking low-risk, short-term investment options backed by the U.S. government. Whether you’re new to fixed-income securities or looking for a safer alternative to stocks and savings accounts, Treasury bills offer a reliable place to park your money with predictable returns. In this comprehensive guide, we will explore what T-bills are, how to calculate their yields, where to buy them, and the advantages they offer for your portfolio.
What Are Treasury Bills?
Definition and Characteristics
Treasury bills, commonly known as T-bills, are short-term debt obligations issued by the U.S. Department of the Treasury. They have maturities of one year or less and are typically sold in increments of $1,000. Unlike bonds or notes, which have longer durations, T-bills mature quickly and provide investors with a safe, liquid investment vehicle.
Key points about T-bills include:
- Maturity: Typically range from 4 weeks up to 52 weeks (one year).
- Denominations: Usually sold in $1,000 increments, with the possibility of purchasing up to $5 million at a time.
- Backing: Fully backed by the U.S. government, making them one of the safest investments.
- Discounted Purchase: T-bills do not pay periodic interest. Instead, they are sold at a discount to face value and mature at par ($100 per $100 face value).
How T-bills Differ from Other Treasury Securities
Treasury securities come in various forms based on their maturity:
- T-bills: Less than one year
- Treasury notes: 2 to 10 years
- Treasury bonds: 20 to 30 years
- TIPS (Treasury Inflation-Protected Securities): Protect investors from inflation
- FRNs (Floating Rate Notes): Variable interest rates
This guide focuses solely on T-bills due to their short-term nature and suitability for conservative investors.
Understanding T-Bill Yields and Auction Process
How T-Bill Yields Are Calculated
Because T-bills are sold at a discount and mature at face value, the yield represents the difference between the purchase price and the amount received at maturity. For example, if you buy a T-bill for $99.75 and it matures at $100, the $0.25 difference is your earnings for the holding period.
To annualize this yield (express it as an annual interest rate), follow these steps:
- Subtract the purchase price from $100 to find the interest earned.
- Divide the interest by the purchase price to get the yield for the holding period.
- Divide by the number of days until maturity to find the daily rate.
- Multiply the daily rate by 365 to annualize it.
This formula helps investors compare the yield of T-bills with other investments on a comparable basis.
Treasury Auction Process Explained
T-bills are sold through a competitive auction process managed by the U.S. Treasury. Auctions are held regularly, and investors can submit bids either directly or through brokers. Key dates related to auctions include:
- Auction Date: When bids are submitted and rates are determined.
- Issue Date: When the T-bills are issued and the investment officially begins.
- Maturity Date: When the T-bill matures and the investor receives the face value.
The price you pay is based on the auction results, which determine the yield for that issuance. Investors may choose to place a competitive bid specifying the yield they want or a non-competitive bid accepting the auction yield.
How to Buy Treasury Bills
Buying T-Bills Through TreasuryDirect
The U.S. Treasury’s official platform, TreasuryDirect.gov, allows investors to buy T-bills directly from the government. While the website’s interface may feel outdated to some, it offers several advantages:
- Lower Minimums: Investors can buy T-bills in increments as low as $100.
- Direct Ownership: No intermediaries involved, so your investment is held directly with the Treasury.
- Reinvestment Options: You can choose to automatically reinvest proceeds into new T-bills for up to two years.
- No Fees: Buying directly from Treasury incurs no broker commissions or fees.
To purchase:
- Log in to TreasuryDirect.
- Select “Buy Direct” and choose “Bills.”
- Select the auction date and issue date for the desired T-bill duration.
- Enter the purchase amount and funding source.
- Review and submit the purchase.
Buying T-Bills Through Brokerages
Brokerage firms like Charles Schwab, Fidelity, and TD Ameritrade provide an easier and more familiar platform for many investors to buy T-bills. Advantages include:
- Ease of Use: User-friendly interfaces integrated with other investment accounts.
- Market Orders: Ability to buy T-bills at auction prices without complicated bidding.
- Auto Roll-Over: Option to automatically reinvest proceeds into new T-bills with similar durations.
- No Commissions: Many brokers offer T-bill purchases commission-free.
To buy T-bills on a brokerage platform:
- Navigate to the fixed income or bonds section.

Why Invest in Treasury Bills?
Safety and Low Risk
T-bills are among the safest investments because they are backed by the full faith and credit of the U.S. government. This makes them a preferred option for risk-averse investors or those looking to preserve capital.
Better Returns Compared to Savings Accounts
While savings accounts and money market funds offer liquidity, their yields often lag behind inflation or the returns from T-bills. For example, at the time of writing, a typical savings account might yield around 2.2%, whereas recent four-week T-bills have offered annualized yields exceeding 3.3%. This yield gap makes T-bills an attractive alternative for short-term, low-risk investing.
Flexibility and Liquidity
With maturities ranging from 4 to 52 weeks, T-bills offer flexibility to suit various investment horizons. Investors can ladder T-bills by staggering purchase dates and maturities to maintain steady liquidity and optimize returns.
Hedge Against Market Volatility
For investors concerned about stock market volatility or uncertain economic conditions, T-bills provide a safe harbor. They help reduce portfolio risk by offering stable returns and safeguarding principal.
Tips for Investing in Treasury Bills
Consider Laddering Your T-Bills
A laddering strategy involves buying multiple T-bills with different maturity dates. This approach helps diversify interest rate risk and improves liquidity by staggering when investments mature.
Monitor Auction Dates and Rates
Stay informed about upcoming Treasury auctions and prevailing yields. Rates can fluctuate with economic conditions, so timing your purchases can optimize returns.
Use Auto Reinvestment for Compounding
If you plan to invest in T-bills for the long term, consider using auto roll-over features offered by brokers or TreasuryDirect to automatically reinvest proceeds into new T-bills.
Combine T-Bills with Other Fixed-Income Securities
Balance your portfolio by including Treasury notes, bonds, or inflation-protected securities alongside T-bills to meet both short-term and long-term financial goals.
