A CD ladder is one of the most popular strategies for balancing higher yields with regular access to your money. Here's how it works.
The Basic Concept
Instead of putting all your money in one CD, you split it across multiple CDs with different maturity dates. As each CD matures, you reinvest at the longest term — capturing higher long-term rates while having funds available at regular intervals.
How a 5-Year CD Ladder Works
Say you have $25,000 to invest. You split it into 5 equal parts:
| CD | Amount | Term | Matures In |
|---|---|---|---|
| Rung 1 | $5,000 | 1 year | Year 1 |
| Rung 2 | $5,000 | 2 years | Year 2 |
| Rung 3 | $5,000 | 3 years | Year 3 |
| Rung 4 | $5,000 | 4 years | Year 4 |
| Rung 5 | $5,000 | 5 years | Year 5 |
What happens next:
- Year 1: Rung 1 matures → reinvest in a new 5-year CD
- Year 2: Rung 2 matures → reinvest in a new 5-year CD
- Year 3: Rung 3 matures → reinvest in a new 5-year CD
- ...and so on
After 5 years, you have all 5 CDs earning 5-year rates, but one matures every year — giving you annual liquidity.
Why Build a CD Ladder?
1. Capture Higher Rates
Longer-term CDs typically offer higher APYs. A ladder lets you earn those rates without locking up everything for 5 years.
2. Regular Liquidity
One CD matures every year, so you always have access to a portion of your funds — without paying early withdrawal penalties.
3. Interest Rate Flexibility
If rates rise, your maturing CDs can be reinvested at the new higher rate. If rates fall, your existing longer-term CDs are still locked in at the older, higher rate.
4. Reduced Reinvestment Risk
By staggering maturities, you avoid the risk of having all your CDs mature when rates are at a low point.
When a CD Ladder Makes Sense
✅ You want better rates than a savings account but need some liquidity ✅ You believe rates will stay flat or rise ✅ You have a medium-term savings goal (3–10 years) ✅ You want a low-risk, predictable return
When a CD Ladder Doesn't Make Sense
❌ You might need all the money suddenly — use a high-yield savings account instead ❌ Rates are expected to drop sharply — consider locking in long-term CDs now ❌ You have a very small amount — the setup effort isn't worth it
Variations on the Classic Ladder
The Barbell
Split between short-term and long-term CDs only (skip the middle). This gives maximum flexibility on one end and maximum yield on the other.
The Bullet
All CDs mature at the same future date. Useful if you have a specific goal (e.g., buying a house in 5 years).
The Steepener
Weight more toward longer-term CDs for higher yield, accepting less frequent liquidity.
How to Build Your Ladder
- Decide your total investment amount
- Choose the number of rungs (3, 5, or 12 are common)
- Divide equally (or weight toward longer terms for higher yield)
- Open CDs at the same bank or spread across institutions for FDIC coverage
- Set a calendar reminder for each maturity date to reinvest
Or use our CD Ladder Calculator to model different ladder configurations and see projected earnings over time.
Key Takeaways
- A CD ladder balances yield and liquidity by staggering maturity dates
- After the initial setup, one CD matures every year for reinvestment
- It's ideal for medium-term savers who want predictable, low-risk returns
- Variations (barbell, bullet) let you customize for your goals
