What is a CD ladder?

A CD (Certificate of Deposit) ladder is a savings strategy where you spread your savings across multiple CDs with staggered maturity dates instead of putting all your money in one CD. This gives you regular access to a portion of your savings while still benefiting from the higher interest rates of longer-term CDs.

How it works

Example: invest $10,000 equally across five CDs: 1-year, 2-year, 3-year, 4-year, and 5-year. When the 1-year CD matures, reinvest it as a new 5-year CD. After 5 years, you have five CDs all maturing annually at the 5-year rate - maximum yield with annual liquidity.

Advantages

  • Liquidity: a portion of your money is always maturing soon.
  • Higher average yield: longer-term CDs pay more interest than short-term ones or savings accounts.
  • Rate protection: spreading maturities means you'll reinvest at different interest rate environments, averaging out rate risk.

Current rate environment

CD rates fluctuate significantly with the federal funds rate. When rates are rising, a ladder benefits from reinvesting maturing short-term CDs at higher rates. When rates are falling, the longer-term rungs lock in higher rates before they drop. For current rates, check the FDIC National Rate and Rate Cap data or a rate aggregator such as Bankrate or NerdWallet. Always verify rates directly with your institution before opening a CD.

Disadvantages

  • Early withdrawal penalties: withdrawing funds from a CD before maturity typically incurs a penalty of 90–180 days of interest (varies by term and bank). This reduces flexibility in genuine emergencies.
  • Less flexible than HYSA: a high-yield savings account offers similar or comparable rates in some interest rate environments with immediate access to funds and no penalty. Compare current HYSA rates before committing to a CD ladder.
  • FDIC insurance limit: FDIC insurance covers up to $250,000 per depositor per institution per ownership category. Large CD ladders across a single bank may exceed this limit.

Step-up CDs and callable CDs

  • Step-up CDs: interest rate increases at scheduled intervals during the term. Useful in rising rate environments, but the base rate is usually lower than a comparable fixed-rate CD.
  • Callable CDs: the bank can terminate the CD early (paying the full principal and accrued interest) if rates fall, eliminating your high-rate lock-in at the worst possible time. Understand the call provisions before purchasing.
