Step by step
How to build a CD ladder
To build a CD ladder: decide how far out it should reach, split the money evenly across four or five rungs, shop each term separately for a real rate, open every CD on the same day, and roll each maturing rung into a new CD at the longest term. One full cycle and the whole ladder earns the long rate.
The build
Six steps to a working ladder
None of this is difficult. The order matters more than the arithmetic: the horizon decides the rungs, the rungs decide the split, and the shopping decides what you actually earn.
Decide how far out the ladder should reach
The longest rung is the real decision, because it sets how long part of your money is committed. Work backwards from when you might need it: a ladder for a cash reserve tops out at twelve months, one for near-term retirement spending at three to five years. Do not build past your horizon to chase a rate.
Choose how many rungs and how far apart
Rungs equal decision points. Five rungs twelve months apart is the classic; four rungs three months apart turns the same money into a rolling one-year reserve. More rungs means more frequent access and more paperwork, and it slightly lowers the blended rate because more of the money sits in shorter terms.
Split the money, then check two limits
Divide the total evenly across the rungs. Then check each bank's minimum deposit, commonly 500 to 1,000 dollars per CD, so every rung clears it. And check the ceiling: FDIC insurance covers 250,000 dollars per depositor, per insured bank, per ownership category, so a large ladder needs rungs spread across institutions or ownership categories.
Shop every term separately
This is the step that makes the most difference and the one most people skip. Rates are set per term, and no single bank leads at all of them. The published FDIC national averages are deposit-weighted, so they are dragged down by the largest banks; nationally available banks and credit unions routinely pay materially more. Get a real quote for each rung before you open anything.
Open the CDs and write down the dates
Fund every rung on the same day so the maturities land where you planned. Record each maturity date, the amount, and the institution somewhere you will actually look — a calendar reminder ten days before each date is enough. Turn off automatic renewal now, while you are thinking about it, not later.
Roll each maturing rung to the back
When the shortest rung matures you get a grace period, usually seven to ten days. Inside it, either take the cash or buy a new CD at the longest term on the ladder — shopped again, not renewed by default. Do that at every maturity and after one full cycle every rung is earning the long rate.
Worked example
$60,000 across five annual rungs
Split $60,000 into five pieces of $12,000 and buy one CD at each year from one to five, priced at the FDIC national average (deposit-weighted) for each term from the July 2026 release. Here is what happens in each of the next five years, and what you do about it.

| Year | Rung maturing | Rate it was earning | Cash back | The decision |
|---|---|---|---|---|
| Jul 2027 | 12 months rung | 1.68% | $12,202 | Spend it, or buy a new five-year CD at whatever the best five-year rate is that year |
| Jul 2028 | 2 years rung | 1.56% | $12,377 | Spend it, or buy a new five-year CD at whatever the best five-year rate is that year |
| Jul 2029 | 3 years rung | 1.34% | $12,489 | Spend it, or buy a new five-year CD at whatever the best five-year rate is that year |
| Jul 2030 | 4 years rung | 1.26% | $12,616 | Spend it, or buy a new five-year CD at whatever the best five-year rate is that year |
| Jul 2031 | 5 years rung | 1.36% | $12,839 | The ladder has fully turned over; every remaining rung is a five-year CD you bought in a different year |

These are FDIC national averages (deposit-weighted) across every FDIC-insured institution, and the largest banks pay close to nothing on deposits while holding enormous balances, which drags the averages down. A well-shopped CD from a nationally available bank or credit union routinely pays materially more than the figure shown here. Read these as the middle of the market, not as a rate you have been offered. Compare them against real quotes on the FDIC National Rates and Rate Caps page, which is where these figures are published.
Over the full five years that ladder pays $2,523 of interest on $60,000, a blended 1.38% a year. That blended figure is a genuine internal rate of return across every rung and every payment date, not the average of the five rates, so the longer rungs count for more.
Notice what the fourth column does not say. It cannot tell you what rate the new five-year CD will pay, because nobody knows what rates will be in a year. That unknown is the honest centre of laddering: the ladder spreads the guess across five different years instead of betting the whole balance on one day, but the guess is still there. Change the amount, the rungs or the spacing in the ladder builder to see how the shape moves, and check the current CD ladder rates before you set the terms.
Where to open them
Bank CDs or brokered CDs
You can build the same ladder two ways: one CD at a time directly with banks, or from a brokerage account that lists many issuers at once. Bank CDs are simpler and let you break a rung for a known penalty — the CFPB's explainer on what a certificate of deposit is covers the disclosures a bank owes you before you open one. Brokered CDs make shopping and insurance coverage easier, and they introduce two traps worth knowing about.
Swipe sideways for the full table →
| Bank CD | Brokered CD | |
|---|---|---|
| How you buy | Open the CD directly with the bank or credit union, online or in branch | Buy through a brokerage account from the CD inventory it lists |
| Shopping across banks | One application per institution; you go and find each rate yourself | Many issuers listed side by side in one screen, easy to compare by term |
| Getting out early | Early withdrawal is allowed and costs a penalty, commonly three to twelve months of interest | No penalty, but no early withdrawal either — you sell it on the secondary market at whatever price it brings |
| FDIC insurance | 250,000 dollars per depositor, per insured bank, per ownership category | Same limits, applied per issuing bank, so one account can hold several banks' worth of coverage |
| Callable risk | Rare | Common — a callable CD lets the issuer end it early if rates fall, which hands you the reinvestment problem at the worst moment. Check before you buy |
| What happens at maturity | Frequently auto-renews at the posted rate unless you act inside the grace period | Proceeds land as cash in the brokerage account; nothing renews on its own |
The two brokered traps are the last two rows. A callable CD can be ended early by the issuer, which almost always happens when rates have fallen and reinvesting is worst for you — read the term sheet. And a brokered CD has no early-withdrawal penalty because it has no early withdrawal at all: if you need out, you sell it, and the price moves with rates exactly the way a bond's does.
Inside an IRA
How to ladder CDs in an IRA
A CD ladder inside an IRA is built exactly the same way, with one real advantage and one real constraint. The advantage is tax: in a taxable account, CD interest is generally taxed as ordinary income in the year it accrues, even on a five-year CD that pays nothing until maturity, so you owe tax on money you have not received. Inside an IRA that problem disappears.
The constraint is the custodian. Bank IRA CDs mean one application per institution, which makes a multi-bank ladder tedious; brokered CDs inside one IRA brokerage account are the usual answer, because a single account can hold rungs issued by several different banks and keep each one separately within FDIC limits. Maturity proceeds arrive as cash in the account, and nothing renews on its own, so the rolling decision stays yours.
If the ladder is funding required minimum distributions, set the maturity dates ahead of the distribution dates rather than on them, so a rung is already cash when the withdrawal is due. Self-directed IRA investors sometimes hold other fixed-schedule assets alongside a CD ladder in the same account; how that works is covered in our self-directed IRA guide.

Avoid these
Mistakes that quietly cost you
Most ladders that disappoint were not built wrong; they were left alone. Automatic renewal is the single largest leak, because a rung that rolls over at the posted rate turns a deliberate decision into a default one, and posted renewal rates are rarely competitive. Turn auto-renewal off when you open each CD.
The second leak is convenience. Building every rung at the bank that already holds your checking account is easy and usually means accepting something near the FDIC national average rather than near the top of the market. Rates are set per term and no one institution leads at all of them, so shopping the five-year rung is a different exercise from shopping the one-year rung.
Three more, briefly. Building the ladder longer than your actual horizon commits money you may want back, and on a flat or inverted curve you may not even be paid for the wait. Ignoring the FDIC ceiling leaves the balance above 250,000 dollars at one bank uninsured — spread it across institutions or ownership categories. And in a taxable account, remember the tax accrues yearly even when the CD pays at maturity, so keep some of the interest available rather than locking every dollar away.
The last one is subtler: treating the blended rate as the ladder's return forever. It is the return on the rungs you own now. Each maturity re-prices a fifth of the ladder at rates nobody can quote you today, which is the trade-off explained in full on what a CD ladder is.
A different structure
When the rolling itself is the problem
Every step above ends in the same place: a rung matures and you buy again at an unknown rate. For most money that is fine, and a CD ladder is the right tool. For the part of a portfolio meant to produce a known income for a long time, some investors would rather set the rate once. That is what Pacific Structured Assets places — court-approved secondary-market payment streams, bought at a discount to a fixed schedule of payments, so the estimated yield is fixed at purchase for the life of the schedule and nothing has to be rolled.
The trade is real and runs the other way on both of the things that make a CD ladder work. A payment stream is not a bank deposit and not FDIC-insured, and it is not an annuity, an insurance product, or a registered security; it depends on one insurer's obligation. Its liquidity is limited — there is no public market and no daily price, and while resale or reassignment may be possible with our assistance, neither the sale nor the price is guaranteed. It is long money, not ladder money. The full comparison, including where the ladder wins, is on payment streams versus a bond ladder.
