CD Laddering Strategy: How to Build a CD Ladder

July 16, 2026

A single CD forces a choice: lock in today’s rate for the full term, or keep everything liquid and miss out on the higher rate. A CD ladder splits the difference by staggering maturity dates across several CDs instead of one.

Step 1 — Understand the Core Tradeoff a Ladder Solves

A single long-term CD locks in a good rate but ties up the entire sum until maturity — if rates rise during that time, you’re stuck at the old rate, and if you need cash early, you eat the early withdrawal penalty. A single short-term CD stays flexible but forces you to accept whatever rate is available every time it matures. Laddering spreads a lump sum across both ends of this tradeoff at once.

Step 2 — Divide Your Total Into Equal Rungs

Split your total deposit into equal portions — a common structure uses 5 rungs with terms of 1, 2, 3, 4, and 5 years, though any number of rungs and any term spacing works depending on your goals and how often you want access to a portion of the funds.

Step 3 — Buy All Rungs at Today’s Rates

Open all the CDs at once, each at its respective term’s current APY. Use the CD calculator to project each rung’s value at maturity individually — a 1-year rung, a 2-year rung, and so on — so you know exactly what each portion will be worth when it comes due.

Step 4 — Reinvest Each Rung Into a New Long-Term CD as It Matures

When the 1-year rung matures, roll it into a new 5-year CD at whatever rate is then available. A year later, the original 2-year rung matures and also rolls into a new 5-year CD. Repeating this each year means that after the ladder is fully established, you have a CD maturing every single year — some access to funds annually, while the bulk of the money stays invested in longer, typically higher-rate terms.

Step 5 — A Worked 5-Rung Ladder Example

$50,000 split into five $10,000 rungs, 1 through 5 years, at rates rising with term length:

Rung	Term	APY	Value at Maturity (via CD calculator)
1	1 year	4.0%	$10,400
2	2 years	4.3%	$10,878
3	3 years	4.5%	$11,412
4	4 years	4.7%	$12,017
5	5 years	4.9%	$12,702

After year 1, the $10,400 from Rung 1 matures and gets reinvested into a new 5-year CD at whatever the current rate is then — the ladder is now “walking forward” one rung at a time, with a CD maturing every year going forward.

Step 6 — Weigh the Tradeoffs Against a Single CD or Savings Account

A ladder generally earns more than keeping everything in a single short-term CD or savings account (since some funds are locked into longer, typically higher-yield terms), while offering more liquidity than putting the entire sum into one long-term CD (since a portion matures every year). It won’t outperform a single CD locked at the longest rung’s rate the whole time, and it’s more effort to manage than a single account. See CD vs. high-yield savings vs. Treasury bills for how laddering compares against other places to park the same cash.

Step 7 — Watch Early Withdrawal Penalties Between Rungs

If you need to break a rung before its maturity date, the same early withdrawal penalty rules apply as any other CD. See the CD terms glossary for how that penalty typically works, and factor it in before assuming a ladder gives you fully penalty-free access to funds mid-term — only the rung that’s actually matured is penalty-free.
