The fundamental tension with CDs is straightforward: longer terms generally pay higher rates, but they lock up your money for longer. A CD ladder resolves this tension by splitting your savings across multiple CDs with different maturity dates, so you capture higher rates while ensuring that money regularly becomes available without penalty. It’s one of the most practical fixed-income strategies for individual savers and requires no ongoing management once set up.
How a CD Ladder Works
Instead of putting all your savings into one CD, you divide it into equal portions and buy CDs with staggered maturity dates. The most common version is a 5-year ladder: you open five CDs with terms of 1, 2, 3, 4, and 5 years simultaneously. Each year, one CD matures. You then reinvest the proceeds — principal plus interest — into a new 5-year CD. After the initial setup period, you permanently have a 5-year CD maturing every 12 months.
| $10,000 | 1-Year CD | Matures Year 1 → reinvest in 5-year |
| $10,000 | 2-Year CD | Matures Year 2 → reinvest in 5-year |
| $10,000 | 3-Year CD | Matures Year 3 → reinvest in 5-year |
| $10,000 | 4-Year CD | Matures Year 4 → reinvest in 5-year |
| $10,000 | 5-Year CD | Matures Year 5 → reinvest in 5-year |
After year 5, all five CDs are at the 5-year rate and one matures annually.
Why Laddering Beats a Single CD
Three advantages work together:
Higher Average Rate
Longer-term CDs typically pay more than shorter-term ones (though this varies with the interest rate environment). A ladder captures the higher rates on your longer rungs while shorter rungs provide liquidity, producing a blended rate better than putting everything in a 1-year CD.
Built-In Liquidity
With one CD maturing every year, you always have access to a portion of your savings without paying an early withdrawal penalty. If you need the money at maturity, you take it. If you don’t, you reinvest into the highest available rate at that time.
Interest Rate Flexibility
A ladder protects against both rising and falling rates. If rates rise, your maturing rungs reinvest at the new higher rate, giving you gradual exposure to better rates without having all your money locked into yesterday’s terms. If rates fall, your longer-term rungs are still locked in at the higher rates you secured earlier.
Step-by-Step: Building Your First CD Ladder
- Determine the total amount — how much of your savings you want in CDs. Keep your emergency fund (3–6 months of expenses) in a liquid account; ladder only the savings beyond that.
- Choose your ladder length — 3-year and 5-year ladders are most common. Shorter ladders (1–3 year) suit savers who want faster reinvestment flexibility. Longer ones (5–7 year) work when the rate curve is steep enough to justify locking in further.
- Divide equally — split the total amount by the number of rungs. $30,000 in a 3-year ladder means $10,000 in each of 1-year, 2-year, and 3-year CDs.
- Shop rates across institutions — online banks and credit unions consistently offer the best CD rates. Don’t limit yourself to your primary bank. Use our CD Rate Calculator to compare what different rates and terms produce in total earnings.
- Set a reinvestment rule — when each CD matures, reinvest automatically into the longest rung of your ladder (a new 5-year CD if you run a 5-year ladder). This maintains the structure without decisions each time.
CD Ladder Variations
Short-Term Ladder (3–6 Month Rungs)
For savings you might need within a year, a short-term ladder with 3, 6, 9, and 12-month CDs gives you quarterly access. This competes well with high-yield savings accounts and often beats them on rate while still providing regular liquidity.
Brokered CD Ladder
Brokered CDs, available through brokerage accounts like Fidelity and Schwab, can be sold on the secondary market before maturity — unlike bank CDs, which assess a penalty for early withdrawal. This makes a brokered CD ladder more liquid, though secondary market prices vary. Brokered CDs are also FDIC insured per issuing bank, letting you diversify across multiple banks within a single brokerage account.
Treasury Note Ladder
The same laddering concept works with US Treasury notes, which carry no state income tax on interest (unlike CDs). In high-tax states, a T-note ladder may produce better after-tax returns than an equivalent CD ladder. The I Bonds vs. T-Bills vs. CDs guide covers when Treasuries win on an after-tax basis in more depth.
When a CD Ladder Makes Sense
- You have savings beyond your emergency fund that you don’t need for near-term goals
- CD rates are meaningfully higher than your current HYSA rate
- You want predictable, risk-free returns without stock market exposure
- You’re in or near retirement and want to create a stream of maturing assets for living expenses
