Want to Earn More Interest and Pad Your Savings? Try This CD Strategy
Amid the uncertainty of the direction interest rates may take this year, a CD ladder can offer some financial stability.
Certificate of deposit ladders can be easy sources of dependable investment income if you’re willing to build a ladder by spacing out maturity dates. CD rates can change based on the Federal Reserve’s decision to raise, lower or leave the federal funds rate, so locking in any single CD rate is a bit of a gamble. But by spreading out the maturity dates over time, you’ll know you’re getting dependable rates, which can be particularly welcome amid economic uncertainty.
So, is it worth it to climb the CD ladder? It mostly depends on two things: how much money you have, and how long you’re willing to wait to get it back.
Let’s back up a bit to understand the process.
What’s a CD Ladder?
To understand how a CD ladder works, we first have to discuss how CDs work.
CDs, or certificates of deposit, are one of the few guaranteed investments out there. Stocks rise and fall, and even the interest rate on your savings account changes. When you buy a CD from a bank, you are guaranteed the interest promised to you at the time of purchase.
Why do banks offer CDs? The same reason they offer savings accounts — they want to hang out with your sweet money and let it earn money for them. Of course, with a savings account, you can withdraw your money whenever you want. Banks would prefer to keep your money for a guaranteed amount of time, which is why they created the certificate of deposit.
With a certificate of deposit, you essentially say, “Hi, bank. I will give you this amount of money for a guaranteed amount of time, and will not withdraw it until the deposit term is complete.” Then the bank says, “That is awesome. In exchange, we will give you a guaranteed high interest rate on your deposit.”
Here’s the most important part: You and your bank agree on the CD term length in advance. The longer the term length, the higher interest rate you typically receive.
Since many people don’t want to lock up all of their extra money in CDs that they can’t access for a year or more, they create a CD ladder: an escalating series of CDs that gives you access to the highest interest rates while still making sure you have money in your pocket when you need it.
How Does a CD Ladder Work?
Imagine you want to invest $3,000 in CDs. You want a high interest rate, but you also want access to your money when you need it. So you invest your $3,000 as follows:
- $1,000 in a six-month CD (with a low interest rate)
- $1,000 in a 12-month CD (with a medium interest rate)
- $1,000 in an 18-month CD (with a high interest rate)
At the end of six months, you get your initial $1,000 investment back plus the interest earned. You now have two options:
- Keep the money
- Invest the $1,000 plus interest in an 18-month CD
Another six months pass, and now your 12-month CD comes due. You get your $1,000 investment plus interest, and can either keep it or invest it in an 18-month CD.
Six more months pass, and your first 18-month CD comes due. You can choose to spend it, or you can immediately invest it in another 18-month CD.
Let’s assume you always reinvest your money. From this point on, you have three 18-month CDs, each of which is earning you high interest. Every six months, one of your 18-month CDs comes due. You can spend what you need, and reinvest the rest in another 18-month CD.
It’s often an excellent way to maximize your interest without taking on a lot of financial risk. Set up a series of 18-month CDs or build an even longer ladder that lasts five years or more.
Is It Worth Climbing the CD Ladder Now?
If you have a decent amount of savings (say $1,000 or more) and you want the security of a guaranteed return, a CD ladder is a great choice.
Longer-term CDs typically give you much higher returns — but not always. For example, the average rate in July 2026 was 1.38% for a 6-month CD and 1.65% for a 12-month CD, according to the FDIC. But for a a 24-month CD, the average rate was 1.53%.
Why was it lower? In part, it has to do with the Federal Reserve. The central bank looks the state of the US economy at its nearly monthly meetings and votes on the federal funds rate. It may lower interest rates to give the economy a boost (typically because of rising unemployment) or raise the federal funds rate if the economy needs to cool down (typically because of higher inflation).
Since January, the Fed has voted to maintain the current interest rate. Many economists predict the Fed will raise interest rates in the short term to help cool rising inflation but the Fed may lower interest rates in the longer term if it can get inflation under control. CD rates generally follow that trend.
But slightly lower rates for longer-term CDs could still benefit your finances, especially if the Fed decides to lower interest rates sooner than expected. And either way, you’ll know the rate of return you’re getting by locking in a CD.
Your local bank likely has CD ladder options, and most online banking options let you create a CD ladder in minutes.
