If you want the high interest rates of a long-term Certificate of Deposit but hate the idea of locking your money away for years, you have a problem. A CD ladder is the exact solution. Building a CD ladder allows you to capture top-tier interest earnings while maintaining regular, penalty-free access to your cash.
In this guide, you will learn exactly what a CD ladder is, how to build one step-by-step, and how to calculate your guaranteed returns.
How Does a CD Ladder Work?
Think of a CD ladder as an assembly line for your savings. Instead of putting all your money into a single 5-year CD, you split your cash into multiple, smaller CDs with staggered maturity dates (terms).
For example, if you have $10,000, you don't put it all into one account. You divide the $10,000 into five chunks of $2,000. You then open five separate CDs: a 1-year, 2-year, 3-year, 4-year, and 5-year CD.
Key Takeaway: By staggering your maturity dates, you ensure that a portion of your money becomes available exactly once a year.
When your 1-year CD matures, what do you do? You immediately take that cash and reinvest it into a brand new 5-year CD at the back of the line. Your ladder is now fully functioning.
The Benefits of CD Laddering
Building a ladder offers two massive advantages over traditional savings strategies.
First, you get higher interest rates. Historically, banks pay much higher APYs for 5-year CDs than they do for 1-year CDs. Because your ladder eventually rolls everything into 5-year terms, your entire portfolio earns the highest possible market rate.
Second, you retain high liquidity. You never have to worry about paying an early withdrawal penalty because you always have a CD maturing in the near future. If an emergency happens, you just wait for the next "rung" of your ladder to mature.
Step-by-Step Example of Building a Ladder
Let's walk through a real-world example so you can set this up at your own bank today. Assume you have $50,000 to invest.
- Open a 1-Year CD with $10,000.
- Open a 2-Year CD with $10,000.
- Open a 3-Year CD with $10,000.
- Open a 4-Year CD with $10,000.
- Open a 5-Year CD with $10,000.
After exactly one year, your 1-year CD will mature. You will receive your $10,000 back, plus the interest. You now open a brand new 5-year CD with that money.
Pro Tip: Not sure how much interest you'll actually earn after taxes? Use our free CD Calculator to model your exact returns for each "rung" of your ladder before you commit your money.
By year five, every single CD you own will be earning the premium 5-year interest rate, but you will still have a chunk of cash becoming completely liquid every twelve months.
Is a CD Ladder Right for You?
You should build a CD ladder if you want guaranteed, zero-risk returns that beat inflation, but you also value conservative flexibility. It is the perfect middle-ground between the low rates of a traditional savings account and the high volatility of the stock market.
If you are trying to decide whether to keep your money liquid or lock it down, you don't have to choose. Build the ladder, and you comfortably get the best of both worlds.
