A Treasury bill ladder is a simple way to earn Treasury yields while keeping regular access to cash. Instead of putting all your money into one bill, you split it across several maturities so part of the ladder matures every few weeks or months.
TreasuryDirect makes this possible without a brokerage account, though the interface is not as flexible as a modern brokerage platform. The advantage is direct ownership of Treasury securities. The tradeoff is less convenient secondary-market liquidity.

What a T-Bill Ladder Does
A ladder spreads maturities across time. For example, a 13-week ladder might have money maturing every four weeks.
Example:
| Week | Action |
|---|---|
| Week 1 | Buy 4-week bill |
| Week 1 | Buy 8-week bill |
| Week 1 | Buy 13-week bill |
| Week 5 | 4-week bill matures; buy another 13-week bill |
| Week 9 | 8-week bill matures; buy another 13-week bill |
| Week 14 | 13-week bill matures; buy another 13-week bill |
After the ladder is running, cash becomes available at regular intervals.
Common T-Bill Maturities
Treasury bills are short-term securities with maturities of one year or less. Common auction maturities include:
- 4-week bills
- 8-week bills
- 13-week bills
- 17-week bills
- 26-week bills
- 52-week bills
Shorter bills give faster access to cash and adjust more quickly to current rates. Longer bills lock the yield for longer but reduce flexibility.
Step-by-Step TreasuryDirect Ladder
- Decide how much cash belongs in the ladder.
- Keep immediate emergency money in a bank account.
- Choose ladder spacing, such as every 4 weeks.
- Buy several bills with different maturities.
- Turn on reinvestment only for money you do not need.
- Track maturity dates in a calendar.
- Reassess rates and cash needs monthly.
TreasuryDirect purchases are made through noncompetitive bids for individual investors. That means you accept the auction rate rather than specifying a yield.
Example: $12,000 Short-Term Ladder
Suppose you want to ladder $12,000 while keeping another $5,000 in a savings account.
You could buy:
| Security | Amount | Purpose |
|---|---|---|
| 4-week T-bill | $4,000 | Near-term liquidity |
| 8-week T-bill | $4,000 | Second maturity |
| 13-week T-bill | $4,000 | Third maturity |
When the 4-week bill matures, you can either take the cash or buy a new 13-week bill. Over time, the ladder creates recurring maturities.
Reinvestment: Useful but Not Automatic Planning
TreasuryDirect allows reinvestment for many Treasury securities. Reinvestment can make a ladder easier, but it can also create problems if you forget that a bill is set to roll over.
Use reinvestment when:
- the money is not needed soon
- the maturity schedule matches your plan
- you track all upcoming cash needs
Avoid automatic reinvestment when:
- you need the cash for taxes, tuition, or closing costs
- the ladder is temporary
- you are not checking TreasuryDirect regularly
Taxes
Treasury bill interest is subject to federal income tax but generally exempt from state and local income tax. This can make T-bills especially attractive in states with higher income taxes.
Treasury bills are bought at a discount and mature at face value. The difference is taxable interest. Your tax form may report the amount after maturity or sale, depending on where and how the bill is held.
TreasuryDirect vs Brokerage Account
TreasuryDirect is good for buying and holding to maturity. A brokerage account may be better if you want easier secondary-market sales, consolidated statements, or the ability to hold Treasury ETFs and money market funds in the same account.
| Feature | TreasuryDirect | Brokerage |
|---|---|---|
| Direct auction access | Yes | Usually yes |
| Secondary market sale | Limited and less convenient | Usually easier |
| Automatic reinvestment | Available for many securities | Depends on broker |
| Interface | Functional | Usually easier |
| Best use | Hold to maturity | Flexible cash management |
Bottom Line
A T-bill ladder works best for cash with known future use and a timeline measured in weeks or months. Keep immediate emergency funds in a bank account, ladder the portion you can wait for, and use reinvestment only when the maturity schedule still fits your life.
