CD Ladder: What It Is and How To Build One

Many certificates of deposit (CDs) offer higher interest rates than traditional savings accounts. But there’s a catch. Locking all your savings into one CD could leave you without easy access to your money until the term ends, unless you’re willing to pay an early withdrawal penalty. 

A CD ladder offers a middle ground. Instead of investing all your money into a single CD, you divide it among several CDs with different maturity dates. That approach can help you earn competitive CD rates while still giving you regular opportunities to access some of your savings. Here’s how a CD ladder works, how to build one, and when it might make more sense than a savings account or a single CD, depending on your savings goals.

Key Takeaways

• A CD ladder spreads your savings across multiple CDs with staggered maturity dates: Instead of locking everything into one term, you get regular access to a portion of your money.

• It balances higher rates with flexibility: You can capture the better yields on longer-term CDs while still having one mature on a regular schedule.

• Building one is simple: Divide your savings into equal deposits across CDs of different lengths — for example, $1,000 each in one- through five-year CDs.

• It eases interest rate guesswork: As each CD matures, you can reinvest at a higher rate if rates rise, while money stays locked in if rates fall.

• It fits medium-term goals: A ladder works best for a two-to-five-year timeline, like a down payment or car purchase, not emergency savings.

• Early withdrawals still cost you: Cashing out a CD before maturity triggers a penalty, so keep your emergency fund in a more liquid account.

What Is a CD Ladder?

A CD ladder is a savings strategy that helps you spread your money across multiple certificates of deposit with staggered maturity dates instead of putting all of your cash into a single account. As each CD matures, you have options. You can withdraw the money if you need it, reinvest it into a new CD to keep the ladder going, or put your savings toward another goal.

Because your CDs in your ladder mature on different schedules, you don’t have to wait years to access all of your savings. At the same time, you may still be able to earn higher rates often available on longer-term CDs.

How a CD Ladder Works

To build a CD ladder, start by dividing your savings into several smaller amounts. Next, deposit each portion into a CD with a different term length. For example, you might choose one-, two-, three-, four-, and five-year CDs.

Each time one of your CDs matures, you’ll have a choice. You can withdraw the money if you need it or reinvest it into a new long-term CD to keep the ladder going. Instead of locking up all of your savings until the same maturity date, a CD ladder gives you regular opportunities to decide what to do with a portion of your money.

Example of a Basic CD Ladder

Imagine you have $5,000 to save and want to build a five-year CD ladder. You could divide your money into five equal deposits of $1,000 and open the following CDs. 

• $1,000 in a one-year CD

• $1,000 in a two-year CD

• $1,000 in a three-year CD

• $1,000 in a four-year CD

• $1,000 in a five-year CD

When the one-year CD matures, you can use the money if you need it or roll it into a new five-year CD. The following year, your original two-year CD matures, giving you the same choice. If you continue reinvesting each maturing CD into a new five-year CD, you’ll eventually have one CD coming due every year. 

Why People Use a CD Ladder

A CD ladder can help you earn higher interest without locking up all of your savings for the same amount of time. Instead of waiting years for a single long-term CD to mature, you’ll have regular opportunities to access part of your money or reinvest it based on your current needs. 

Another advantage is that you don’t have to guess where interest rates are headed. If rates rise, you can reinvest each maturing CD at a potentially higher rate. If rates fall, part of your money remains locked into CDs you opened when rates were higher. That balance of predictable returns and better access to your money makes a CD ladder an appealing option, especially if you’re looking for a more conservative savings solution. 

How To Build a CD Ladder

Setting up a CD ladder doesn’t have to be complicated. The following steps can help you create a simple strategy that works for your savings goals.

Choose the Number of Rungs

Many savers build a ladder with three to five CDs, often called rungs. In general, more rungs mean you’ll have money that becomes available more often. The right number of CDs for your ladder depends on a few factors. Typically, the amount of money you have to save and how frequently you want access to your cash are the most important details to weigh during this process. 

Pick the Longest Maturity

Next, decide how long you want your ladder to run. Three- and five-year CD ladders are common, but the best choice depends on when you’ll need the money and the CD rates available when you open your accounts.

Shop Rates and Reinvest on Schedule

CD rates can vary from one bank or credit union to another, so it’s important to compare offers before you open an account. Afterward, keep an eye on your maturity dates. 

Before a CD comes due, decide whether to withdraw the money or reinvest it. Otherwise, the bank may automatically renew the account for another term. 

When a CD Ladder Makes Sense

A CD ladder can be a smart choice if you have money you won’t need right away but still want to keep somewhat accessible. This type of savings strategy might be a good fit if you: 

• Are saving for a medium-term goal, like a down payment, car purchase or home renovation 

• Want to protect your principal while earning more interest than a traditional savings account may offer 

• Like the idea of having regular access to part of your savings instead of locking up all of your money at once 

When a CD Ladder Does Not Make Sense

A CD ladder can be a useful way to save, but it isn’t the right answer for every situation. You may want to look elsewhere if you:

• Need to keep your emergency savings easy to access

• Are investing for retirement or another goal that’s a decade or more away

• Prefer a savings strategy you can set up once and forget about

Benefits and Drawbacks of a CD Ladder

Like any savings strategy, a CD ladder comes with tradeoffs. Here’s a quick look at the biggest advantages and potential downsides. 

Benefits

• Predictable returns: Your interest rate stays the same for the life of each CD.

• Principal protection: CDs let you grow your savings without exposing your money to stock market swings.

• Regular access to your money: One CD matures at a time, so you don’t have to wait years to access all of your savings.

• Less pressure to time interest rates: You’ll have the chance to reinvest as each CD matures instead of trying to guess the best time to lock in a rate for all your savings.

Drawbacks

• Limited access to your money: You’ll still pay an early withdrawal penalty if you cash out a CD before it matures. 

• Inflation can reduce your buying power: If prices rise faster than your CD earns interest, your savings may not go as far over time.

• Growth potential is limited: CDs can help preserve your savings, but they aren’t designed to deliver the long-term returns you might earn by investing.

CD Ladder vs. Savings Account

A high-yield savings account (HYSA) gives you easy access to your money whenever you need it, making it a better home for your emergency fund or short-term savings. A CD ladder, on the other hand, asks you to commit your money for longer, but you may earn a higher return in exchange. If you’re saving for a goal that’s still a few years away and don’t expect to need every dollar right away, a CD ladder could be worth considering.

Alternatives to a Traditional CD Ladder

A traditional CD ladder works well for many savers, but it isn’t your only option. If you have a shorter savings timeline, a mini CD ladder may be a better fit. Some savers also use more specialized strategies, such as barbell ladders, which combine short- and long-term CDs, or bullet ladders, which time multiple CD maturity dates around a specific savings goal. For many people, keeping it simple works fine. But if you need more flexibility than a CD ladder can offer, a high-yield savings account may be the better choice. 

Bottom Line

A CD ladder can be a smart way to earn more interest without locking up all of your savings for years. It works best when you have a clear goal, a timeline of two to five years, and don’t need immediate access to every dollar. If flexibility is your top priority, a high-yield savings account may make more sense.
