Key takeaways
- A CD ladder divides a sum into several CDs with staggered maturities, for example 1, 2, 3, 4 and 5 years.
- Each time a CD matures, you either use the money or reinvest it at the long end, so one rung comes due every year.
- A ladder balances access (money comes free regularly) with rate (most of it earns longer-term rates) and spreads the risk of locking in at the wrong time.
- Longer CDs do not always pay more: in the FDIC survey of September 21, 2026, the average 12-month CD paid 1.73% and the average 60-month CD 1.38%.
Choosing a CD term is a bet on the future: lock in for five years and rates might rise; stay short and rates might fall. A CD ladder avoids making one big bet. You split your money across several CDs that mature at regular intervals, which gives you regular access to part of the money and a blend of short- and long-term rates.
How a CD ladder works
- Pick the total and the number of rungs. For example, $25,000 in five rungs of $5,000.
- Open CDs with staggered terms: 1 year, 2 years, 3 years, 4 years and 5 years.
- When the 1-year CD matures, use the money if you need it, or reinvest it in a new 5-year CD.
- Repeat every year. After four years, every rung is a 5-year CD, and one of them matures every year.
Once the ladder is complete, all your money earns five-year rates, yet $5,000 becomes available every 12 months without an early withdrawal penalty.
Example: a $25,000 five-year ladder
The APYs below are example rates for illustration, not quotes. Check current offers before you open CDs.
| Rung | Deposit | Example APY | Interest by maturity |
|---|---|---|---|
| 1-year CD | $5,000 | 4.00% | $200.00 |
| 2-year CD | $5,000 | 3.90% | $397.60 |
| 3-year CD | $5,000 | 3.85% | $600.02 |
| 4-year CD | $5,000 | 3.80% | $804.43 |
| 5-year CD | $5,000 | 3.80% | $1,025.00 |
In the first year, the ladder earns about $968, an average APY of 3.87%. If rates fall over the next few years, the longer rungs keep earning their locked-in rates. If rates rise, each maturing rung can be reinvested at the higher rate. You can model each rung with the CD calculator.
A short-term ladder for near-term goals
A ladder does not have to span years. For money you need within a year, such as a tax bill or tuition payments, you could split $12,000 into four CDs of 3, 6, 9 and 12 months. Every three months, $3,000 matures. This is also useful for self-employed people who pay quarterly estimated taxes: each rung can be timed to come due shortly before a payment date.
Why longer CDs do not always pay more
Banks set CD rates based on where they expect interest rates to go. When markets expect the Federal Reserve to cut rates, longer CDs can pay the same or less than shorter ones, an inverted yield curve. The FDIC's national averages on September 21, 2026 showed exactly that:
| Term | National average APY |
|---|---|
| 3 months | 1.13% |
| 6 months | 1.41% |
| 12 months | 1.73% |
| 24 months | 1.61% |
| 36 months | 1.36% |
| 60 months | 1.38% |
When short terms pay more, a ladder still works, but the case for long rungs rests on protection against falling rates rather than a higher rate today. National averages include many large banks that pay little; online banks and credit unions often pay more than twice as much, so compare offers for each rung.
Pros and cons of a CD ladder
| Pros | Cons |
|---|---|
| Regular access to part of the money without penalties | Most of the money is still locked up; breaking a CD early costs a penalty |
| Reduces the risk of locking everything in right before rates rise | Requires attention each time a rung matures |
| Fixed, FDIC-insured returns on each rung | Can earn less than a single long CD if rates fall steadily |
| Easy to match maturities to known expenses | Interest is taxed as ordinary income each year |
Tips for building a ladder
- Shop each rung separately. The best 1-year and 5-year rates are often at different banks.
- Watch the renewal window. Most banks give a grace period of 7 to 10 days at maturity before renewing automatically at the current rate.
- Check early withdrawal penalties before opening long rungs; a 12-month interest penalty on a 5-year CD is common.
- Keep the emergency fund separate. A ladder is not a substitute for cash you can reach today; that belongs in a high-yield savings account.
- Stay within insurance limits. Coverage is $250,000 per depositor, per bank, per ownership category; spread large ladders across banks.
- Consider Treasuries for taxable accounts in high-tax states. A ladder of Treasury bills or notes works the same way and is exempt from state income tax.
Alternatives to a CD ladder
- A single CD when you know exactly when you will need the money; see fixed-term deposits and CDs explained.
- A high-yield savings account for full flexibility, at a variable rate; the trade-offs are in CD vs. high-yield savings.
- No-penalty CDs for a fixed rate with an exit option; see no-penalty CDs.
- Brokered CDs and Treasury ladders bought through a brokerage, which can be sold before maturity at market prices instead of paying a penalty.
Frequently asked questions
How much money do you need for a CD ladder?
As little as the minimum deposit for each CD, often $500 to $1,000, and some online banks have no minimum. A ladder makes the most sense when the total is large enough that the rate difference matters to you.
Is a CD ladder a good idea right now?
It is a good idea whenever you have savings you will not need all at once and want fixed returns without guessing where rates are headed. When short-term CDs pay more than long ones, a shorter ladder may fit better.
What happens when a rung matures?
You can withdraw the money, reinvest it in a new CD at the long end of the ladder or move it elsewhere during the bank's grace period.
Can I build a CD ladder at different banks?
Yes, and it often helps you get the best rate for each term and keeps each bank's balance under the insurance limit.
Are CD ladders better than bonds?
They are simpler and FDIC insured up to the limit, with no price swings if held to maturity. Treasury ladders offer similar safety with state tax benefits and the ability to sell early.
