Ladder breakdown

Every rung, its term, its maturity and what it earns.

Results are estimates based on the values you enter and assume each rung is held to its own maturity. Confirm minimum deposits, terms and rates with your bank or credit union.

A CD ladder calculator shows how to split your money across several CDs with staggered maturity dates. Enter your total amount, the number of rungs, and the rates, and it maps each CD's term, maturity, and interest. A ladder gives you regular access to part of your money while still earning the higher rates that longer terms offer.

How to Use the CD Ladder Calculator

Enter the total amount you want to invest, then choose how many rungs your ladder will have. Set the term for each rung and the APY for each one, since longer terms often carry different rates. The calculator splits your money across the rungs and shows when each CD matures and how much interest it earns.

Adjust the number of rungs or the terms to compare a shorter, more flexible ladder against a longer, higher-yielding one. This helps you match the ladder to your timeline.

What Is a CD Ladder?

A CD ladder is a savings strategy that spreads your money across multiple CDs with different maturity dates. Instead of locking everything into one long-term CD, you divide it so that a portion becomes available at regular intervals. Each individual CD in the ladder is called a rung.

The goal is to capture the higher rates of longer terms while keeping part of your money accessible. As each rung matures, you can withdraw the funds or reinvest them into a new long-term CD to keep the ladder running. This balances liquidity and yield better than a single CD does.

How to Build a CD Ladder

Building a ladder is straightforward once you decide on your goals. Follow these steps to set one up.

Set your total amount and goal

Decide how much to invest and when you may need access to portions of it.

Choose the number of rungs

A common setup is five rungs, though you can build fewer or more depending on how often you want access.

Split the money evenly

Divide your total across the rungs, for example equal amounts in each CD.

Assign staggered terms

Give each rung a different term, such as one through five years, so they mature in sequence.

Reinvest as each rung matures

When the shortest CD matures, roll it into a new long-term CD to keep the ladder going.

Before building a ladder, many savers keep three to six months of expenses in an accessible account, since ladder funds are committed in stages.

CD Ladder Example

The table below shows a $25,000 ladder split into five equal rungs of $5,000, with terms from one to five years. The interest figures use an illustrative 4.00% APY and assume each rung is held to its own maturity. Enter your own amounts and rates in the calculator for exact numbers.

RungAmountTermMaturesInterest at 4.00% APY
1 $5,000 1 year Year 1 $200.00
2 $5,000 2 years Year 2 $408.00
3 $5,000 3 years Year 3 $624.32
4 $5,000 4 years Year 4 $849.29
5 $5,000 5 years Year 5 $1,083.26
Illustrative figures at a 4.00% APY with each rung held to its own maturity.

In year one, the first rung matures and gives you $5,200 in cash. You can spend it or reinvest it into a new five-year CD, which becomes the top rung of your ladder. Repeating this each year eventually gives you a ladder of five-year CDs with one maturing every year.

This structure means you always have a CD maturing soon, while most of your money keeps earning the higher long-term rate. That is the core advantage of laddering.

Types of CD Ladders

Ladders can be shaped to fit different goals. The main variations are below.

Traditional ladder

Equal amounts across terms of one to five years, with each maturing rung reinvested into a new long-term CD. This is the standard, balanced approach.

Mini ladder

Uses short terms such as three, six, and twelve months. It prioritizes flexibility and quicker access over yield.

Barbell ladder

Uses only short-term and long-term CDs, with the middle terms left out. It suits savers who want both quick access and long-term yield but nothing in between.

Bullet ladder

Several CDs opened at different times but all set to mature on the same target date, useful for a known future expense like a down payment.

Pros and Cons of a CD Ladder

A ladder has clear strengths and a few trade-offs worth weighing before you build one.

Pros. You get regular access to portions of your money, you earn higher long-term rates on most of it, and you reduce the risk of locking everything in at one rate. Spreading CDs across multiple insured institutions can also extend your total FDIC or NCUA coverage.

Cons. Your money is still committed in stages, so it is not as liquid as a savings account. Tracking multiple maturity dates takes some effort. If rates rise quickly, the longer rungs can lag current offers until they mature.

CD Ladder vs a Single CD

A single CD locks your entire balance into one rate and one maturity date. If rates rise, you are stuck until it matures. If you need the money early, you pay a penalty on the whole amount. A ladder spreads that risk.

With a ladder, only one rung is tied up at a time before becoming available, so you can respond to rate changes and cash needs more easily. You still earn strong long-term rates on the rungs that are not maturing. For a pure lump sum you will not touch for years, a single CD is simpler, but a ladder usually offers better flexibility.
