A CD ladder spreads your savings across multiple CDs with staggered maturity dates, rather than locking everything into a single term. The goal is balancing the higher rates CDs typically offer against the liquidity concern of having all your funds locked away at once.
How a basic ladder is structured
A common approach divides your total savings into equal portions, placed into CDs with different terms — for instance, one, two, three, and four-year terms. As each CD matures, you have access to a portion of your funds at regular intervals, and you can choose to withdraw that portion, reinvest it in a new long-term CD, or split the decision based on your needs at that time.
A four-rung ladder with one CD maturing each year gives you a liquidity event annually, even though the bulk of your savings is earning the higher rates typically associated with longer terms.
Why this beats locking everything into one term
Putting all your savings into a single long-term CD maximizes the rate but eliminates flexibility until that one maturity date arrives. A ladder sacrifices a small amount of average yield, since shorter-term rungs typically earn somewhat less than the longest-term CD would, in exchange for periodic access without needing to break any CD early or pay a withdrawal penalty.
Maintaining a ladder over time
Once established, a ladder is typically maintained by reinvesting each maturing CD into a new long-term CD, keeping the staggered structure going indefinitely. This way, after the initial setup period, you eventually have a CD maturing every year (or whatever interval you've chosen) while consistently holding longer-term, typically higher-yielding CDs across the rest of the ladder.
- Decide on a ladder interval (such as annual rungs) based on how often you want liquidity events
- Divide your total CD savings evenly, or based on anticipated need, across the chosen terms
- Reinvest each maturing CD into a new long-term CD to maintain the ladder structure going forward
- Reassess the strategy if your liquidity needs or the broader rate environment change significantly
Frequently asked questions
Do all the CDs in a ladder need to be at the same bank?
No, and some savers intentionally spread a ladder across multiple banks, both to compare available rates and to stay within FDIC insurance limits at each individual institution.
Is a CD ladder worth the added complexity for a small amount of savings?
For smaller amounts, the added complexity of managing multiple CDs may outweigh the modest benefit of staggered liquidity — a single high-yield savings account or one CD might be simpler and nearly as effective.
