How to Build a CD Ladder: A Step-by-Step Strategy
If you want better returns than a regular savings account without locking up all your cash at once, a CD ladder solves exactly that trade-off.
What Is a CD Ladder?
A CD ladder is a savings strategy where you split your money across multiple Certificates of Deposit (CDs) with staggered maturity dates, instead of putting it all into one CD.
How a CD Ladder Works
Rather than locking $10,000 into a single 5-year CD, you split it into five $2,000 CDs with terms of 1, 2, 3, 4, and 5 years. As each CD matures, you either use the cash or reinvest it into a new 5-year CD, keeping the ladder going.
Worked Example
Initial setup with $10,000:
- $2,000 in a 1-year CD
- $2,000 in a 2-year CD
- $2,000 in a 3-year CD
- $2,000 in a 4-year CD
- $2,000 in a 5-year CD
After year 1: The 1-year CD matures. You reinvest that $2,000 into a new 5-year CD (since rates and liquidity needs allow). Now you have a CD maturing every year going forward, each time giving you the choice to withdraw or reinvest at current rates.
Why Use a CD Ladder Instead of One CD?
- Regular access to cash — a portion of your money becomes available every year instead of being locked up entirely
- Reduces interest rate risk — if rates rise, you’re not stuck with all your money in an old, lower-rate CD; you can reinvest maturing portions at new, higher rates
- Still earns more than a savings account — longer-term CDs generally offer higher rates than short-term CDs or standard savings accounts
- Flexible and customizable — you can adjust the number of rungs and term lengths based on your own timeline and goals
Who a CD Ladder Makes Sense For
- Savers who want a safer, FDIC-insured alternative to the stock market for part of their savings
- People saving toward a goal with a few years of flexibility (e.g., a down payment in 3-5 years)
- Retirees who want predictable, staggered access to funds without taking market risk
Frequently Asked Questions
How many CDs (rungs) should a ladder have?
There’s no fixed number — 4 to 5 rungs spaced a year apart is common, but you can build a shorter ladder (e.g., 3, 6, 9, 12 months) if you want more frequent access.
What happens if I need the money before a CD matures?
Most CDs charge an early withdrawal penalty (often a few months of interest) if you withdraw before maturity — this is why laddering, rather than locking everything into one long-term CD, helps keep some cash accessible.
Do all the CDs in a ladder need to be from the same bank?
No — you can build a ladder using CDs from different banks, which can also help you capture the best available rate for each term and stay within FDIC insurance limits per institution.
Is a CD ladder better than a high-yield savings account?
It depends on your goals — CDs typically offer fixed, often higher rates than savings accounts, but your money is less liquid. Many savers use both: a high-yield savings account for emergency funds and a CD ladder for money they won’t need immediately.
