What Is a CD Ladder? (And Why You Want One)
A CD ladder is a savings strategy where you spread your money across multiple CDs with different maturity dates. Instead of putting everything into one 5-year CD, you split it across several CDs that mature at different times—say, 1 year, 2 years, 3 years, 4 years, and 5 years.
Here’s the magic: You get the higher yields of long-term CDs, but you also get regular access to your money as each CD matures. And when a CD matures, you can either take the cash or reinvest it at the long end of the ladder—keeping the cycle going.
Example: A 5-Rung Ladder Over 5 Years
| Rung | Term | Amount | Matures In | Interest Earned |
|---|---|---|---|---|
| 1 | 12 months | $5,000 | Year 1 | $225 |
| 2 | 24 months | $5,000 | Year 2 | $459 |
| 3 | 36 months | $5,000 | Year 3 | $703 |
| 4 | 48 months | $5,000 | Year 4 | $956 |
| 5 | 60 months | $5,000 | Year 5 | $1,219 |
| Total Invested: $25,000 | Total Interest: $3,562 | Total Matured: $28,562 |
With this strategy, you have $5,000 becoming available every year—while the rest continues earning at higher long-term rates.
How a CD Ladder Works Step by Step
- Divide your investment across multiple CDs with different terms.
- Each CD matures at a different time (e.g., one every year).
- When a CD matures, you have options:
- Cash out and use the money
- Reinvest into a new CD at the longest term
- Adjust based on current rates and your needs
- The ladder keeps going—each time a CD matures, you reinvest at the long end.
