Certificates of deposit (CDs) offer higher rates than regular savings accounts, but their fixed terms create a problem: if you lock all your money into a single long-term CD, you lose flexibility. A CD ladder solves this by dividing your money across multiple CDs with different maturity dates, so you capture higher rates while still having regular access to portions of your funds.
How a CD Ladder Works
Instead of putting $10,000 into a single 5-year CD, you divide it into five portions of $2,000 each — one 1-year CD, one 2-year CD, one 3-year CD, one 4-year CD, and one 5-year CD. Over the first year, they all earn the interest rate for their term. When the 1-year CD matures, you either use the money (if you need it) or roll it into a new 5-year CD.
After the initial 5-year setup period, one CD matures every year. You always have access to a portion of the money annually, and most of your funds are in longer-term CDs earning higher rates.
Why It Works Better Than a Single CD
A CD ladder solves several problems simultaneously:
Liquidity: If you lock $10,000 in a single 5-year CD and need the money at year 2, you’ll face an early withdrawal penalty — often several months of interest, sometimes more. With a ladder, you have CDs maturing every year, so money becomes available regularly without penalties.
Rate exposure: Interest rates change over time. If you lock all your money into a 1-year CD when rates are high and rates then drop, your money earns lower rates the following year. If you lock everything into a 5-year CD and rates rise, you’re stuck at the lower rate for years. A ladder gives you continuous reinvestment opportunities — each maturing CD can be rolled into a new rate reflecting current conditions.
Higher rates than short-term CDs alone: Most of the time, longer-term CDs pay higher rates than shorter-term ones (though this isn’t always true — there are periods of inverted yield curves when short-term rates exceed long-term rates). By holding some longer-term CDs in your ladder, you earn higher rates on a portion of your money compared to keeping everything in 3-month or 6-month CDs.
Setting Up a CD Ladder
To build a 5-rung CD ladder:
- Determine the total amount you want to ladder
- Divide equally into five portions (or adjust based on when you might need access)
- Open CDs with 1-, 2-, 3-, 4-, and 5-year terms simultaneously
- When each CD matures, roll the proceeds into a new 5-year CD
- After five years, all your CDs are 5-year CDs, with one maturing annually
You don’t have to use 5 rungs or 5 years. A shorter ladder (1-year, 18-month, 2-year, 3-year) works for money you might need sooner. A longer ladder makes sense for savings you’re highly confident won’t be needed for several years.
Where to Open CDs
Online banks and credit unions typically offer significantly better CD rates than traditional brick-and-mortar banks. Comparison sites make it easy to see the current rates at dozens of institutions simultaneously. The FDIC and NCUA insure CDs at member institutions up to the standard limits, so safety is equivalent regardless of whether you use a big bank, online bank, or credit union.
A few things to check before opening a CD:
- Early withdrawal penalty — what does it cost to access money before maturity? More competitive CDs sometimes have steeper penalties; no-penalty CDs exist but typically offer lower rates
- Renewal terms — what happens when the CD matures? Most auto-renew at whatever rate the bank offers at that moment unless you take action. Set a calendar reminder for maturity dates.
- Minimum deposit — some of the highest-rate CDs require minimum deposits of $1,000–$10,000
No-Penalty CDs as an Alternative
No-penalty CDs (also called liquid CDs) allow early withdrawal without a fee after a brief holding period (typically 6–7 days after opening). They typically offer rates higher than savings accounts but lower than standard term CDs. They’re a useful option if you want the higher rate without committing to a fixed term.
Including one or two no-penalty CDs in a ladder adds flexibility for the portion of your savings that might be needed on shorter notice.
CD Ladders vs. High-Yield Savings Accounts
A high-yield savings account offers complete flexibility — no term, no penalty, withdraw anytime — but rates fluctuate with the broader interest rate environment. CD rates lock in for the term, which is an advantage when rates are falling and a disadvantage when they’re rising.
For money with a clear time horizon — saving for a down payment in three years, building a fixed savings reserve — a CD ladder can offer both a reliable rate and periodic access. For a fully liquid emergency fund, a high-yield savings account’s flexibility typically outweighs the marginal rate difference.
