A CD ladder is an investment strategy where you divide your money across multiple CDs with different maturity dates — for example, 1-year, 2-year, 3-year, 4-year, and 5-year CDs. When each CD matures, you reinvest in a new long-term CD, giving you regular access to funds while capturing higher long-term rates.

How many rungs should my CD ladder have?

Most financial experts recommend 3–5 rungs. A 5-rung ladder provides annual access to funds and maximum rate diversification. A 3-rung ladder is simpler and still provides regular liquidity. More rungs mean more complexity but better alignment with the yield curve.

What happens when a CD in my ladder matures?

When a CD matures, you typically have a grace period (often 7–10 days) to decide what to do. In a ladder strategy, you reinvest the proceeds into a new CD at the longest rung of your ladder. This keeps the ladder rolling and ensures you always have a CD maturing annually.

Can I lose money in a CD ladder?

CD principal is generally safe if held at FDIC-insured banks (up to $250,000 per bank). However, if you need to withdraw early, you'll face early withdrawal penalties that could reduce your return. The main risk is opportunity risk — rates may rise after you lock in your CDs.

Should I use a CD ladder or a high-yield savings account?

CD ladders typically offer higher rates than savings accounts and lock in returns for a set period. High-yield savings accounts offer full liquidity but variable rates. A CD ladder is better if you won't need the money for a while. Many investors use both: a CD ladder for the majority and a savings account for an emergency fund.

How a CD Ladder Works

A CD ladder splits your investment across multiple CDs with staggered maturities. For example, with a 5-rung ladder and $50,000:

$10,000 in a 1-year CD at 4.00%
$10,000 in a 2-year CD at 4.30%
$10,000 in a 3-year CD at 4.60%
$10,000 in a 4-year CD at 4.80%
$10,000 in a 5-year CD at 5.00%

Each year, one CD matures. You can spend the money or reinvest in a new 5-year CD, keeping the ladder rolling. Over time, all your money earns long-term rates, but you have annual access.

Frequently Asked Questions

A CD ladder divides your money across multiple CDs with different maturities. When each CD matures, you reinvest it into a new long-term CD. This gives you regular liquidity while capturing higher long-term rates.

3–5 rungs is typical. Five rungs give you annual CD maturities and maximize rate diversification. Three rungs are simpler and work well if you want access every year and prefer fewer accounts to manage.

You'll have a grace period (typically 7–10 days) to decide. In a rolling ladder, you reinvest at the longest rung. If you need funds, you can take them penalty-free. If you miss the grace period, the bank usually auto-renews at the current rate.

Principal is safe at FDIC-insured institutions (up to $250,000 per bank). The risk is early withdrawal penalties if you need funds before maturity, and opportunity risk if rates rise significantly after locking in.

CD ladders generally offer higher rates and lock in returns, while HYSAs offer full liquidity with variable rates. Many investors use both: a CD ladder for stable, higher-yield savings and an HYSA for their emergency fund.
