- A T-bill ladder is a schedule, not a yield strategy: set the maturity dates around when you'll need cash, and keep money for immediate expenses out of it entirely.
- The real question to ask is how long you can safely wait for the next bill to mature if your plans change.
- Selling a Treasury bill before it matures can gain or lose you money on the sale, and can add extra delay moving the funds.
Decision frame
When will you actually need this cash, and how much of a timing slip can your plan handle?
Compare
The next maturity date against the date you actually need the money — not a headline rate against a savings-account rate.
Verify first
Every maturity date, whether reinvestment is turned on, and which account is holding each bill, before you commit the money.
Do not assume
Don't put your whole emergency reserve into T-bills if an expense could come up before the next one matures.
Work backward from the date you'll need the money
A T-bill (Treasury bill) ladder starts with a calendar, not a rate. Write down the amount, the date the cash has to be available, and the earlier point at which a change of plans would start to get expensive. Keep a separate balance on the side for expenses that simply can't wait for a bill to mature, get transferred, or get sold.
Treasury bills mature in one year or less. They're tradeable securities, so a broker can generally sell one before it matures — but doing that turns a simple timing plan into a market-price gamble. A ladder works best when you expect to hold every rung to maturity and just want cash showing up at regular intervals.
Give every dollar one job
- Better place for it
- Checking or an accessible savings account
- Why
- No maturity date, sale, or transfer standing between you and the cash.
- Better place for it
- A short T-bill ladder
- Why
- Staggered maturities give you cash arriving on a predictable schedule.
- Better place for it
- A single Treasury maturity
- Why
- One clear date beats several rungs you don't actually need.
That cash buffer isn't wasted money — it's what keeps you from having to sell or transfer the rest of the ladder under pressure. Only split the scheduled amount across your maturities.
Stress-test the worst case, not the best one
For a goal due in six to nine months, having a few different maturities means some cash becomes available before the final deadline. The number of rungs you choose isn't a rule — it's a tradeoff between how often you want cash showing up and how much bookkeeping you're willing to take on.
Ask yourself: if the expense moves a month earlier than planned, which dollars would actually be available without selling anything? If the answer is none, add more cash outside the ladder, or pick an earlier maturity. If a rung lands close enough to the new date, the schedule probably still works.
Build a rolling Treasury bill ladder using a current annualized rate you enter and estimate rung size, income, and liquidity dates.
Enter a current annualized yield for the maturity you are modeling; Treasury bill quote conventions and reinvestment rates can differ.

What to do
Plan your next move
Pre-tax estimates. For illustration only — not financial advice.
The calculator gives you a planning estimate, not an actual auction result. Plug in the yield you're considering for each maturity, then judge whether the timing actually fits your needs before you look at the projected income.
The account you hold it in changes the plan
TreasuryDirect works well for a simple buy-at-auction, hold-to-maturity routine. A brokerage account can be more practical if the ladder needs to sit alongside your other investments, or if there's a real chance you'll need to sell early. TreasuryDirect requires securities bought there to stay put for 45 business days after purchase before you can move them elsewhere. That restriction can matter more than a small difference in yield for a short-term plan.
Five-minute check before you buy
- Name the payment and the latest acceptable date for the cash, for every rung.
- Keep a separate cash balance set aside for surprises.
- Double-check each actual maturity date rather than just going by a term label like "3-month" or "6-month."
- Turn off automatic reinvestment deliberately — don't let a bill you'll actually need just roll over into a new one.
- Rebuild the schedule whenever the goal date, the amount, or your account setup changes.
