- A 3-year CD ladder uses three rungs — 1-year, 2-year, and 3-year CDs — opened simultaneously, giving you one CD maturing every 12 months.
- The top 3-year CD rate in REBOLST's database is 3.70% (Marcus by Goldman Sachs, $500 min) — nearly identical to the top 1-year rate of 4.00%.
- The flat yield curve means you sacrifice very little yield by locking in a 3-year CD versus a 1-year CD right now — roughly 0.30%.
- Most top online banks do not tier 3-year CD rates by deposit size — you get the same APY whether you deposit $1,000 or $100,000. Traditional banks are more likely to tier.
- Once fully built (after year 3), every maturing CD gets reinvested in a new 3-year CD — giving you perpetual annual liquidity at a fixed rate.
What Is a 3-Year CD Ladder — and How Does It Work?
A CD ladder is a strategy where you split a lump sum across multiple CDs with staggered maturity dates. Instead of putting everything in a single 3-year CD and waiting for it to mature, you open three CDs at the same time — one maturing each year for three years. When each CD matures, you reinvest it at the longest rung of the ladder, which in this case is a new 3-year CD.
The payoff is twofold: you maintain access to a portion of your money every 12 months (without paying an early withdrawal penalty), and over time you accumulate a portfolio of 3-year CDs — typically among the most competitive longer-term rates available — with one maturing annually. The 3-year horizon makes this the most compact ladder that's worth building. A 2-rung ladder (1yr + 2yr) barely qualifies as a strategy; a 3-rung ladder is where the discipline pays off.
How to Build a 3-Year CD Ladder
Split your deposit into three equal parts. Open one 1-year CD, one 2-year CD, and one 3-year CD simultaneously. That's it — the structure is that simple. The setup period is the three years it takes for all rungs to mature and get reinvested into 3-year CDs. Here's what the timeline looks like for a ladder started in July 2026:
| Rung | Term | Opens | Matures | Next Step |
|---|---|---|---|---|
| Rung 1 | 1-Year | July 2026 | July 2027 | Reinvest in 3-Year CD → matures July 2030 |
| Rung 2 | 2-Year | July 2026 | July 2028 | Reinvest in 3-Year CD → matures July 2031 |
| Rung 3 | 3-Year | July 2026 | July 2029 | Reinvest in 3-Year CD → matures July 2032 |
After July 2029, you have three 3-year CDs maturing in 2030, 2031, and 2032 — one per year, every year, indefinitely. That's the fully-built ladder. You give up flexibility during the 3-year setup period, but after that, annual access is permanent as long as you keep reinvesting.
Dividing equally is the simplest approach, but it isn't mandatory. Some savers weight the longest rung more heavily — putting 40–50% in the 3-year CD — to maximize the time earning the highest rate. Others weight the shortest rung to keep more near-term flexibility. Your allocation should reflect when you're most likely to need access to the funds.
Best Rates for Each Rung Right Now

What the Flat Yield Curve Means for Your 3-Year Ladder
In a normal rate environment, longer-term CDs pay meaningfully more than shorter ones — compensation for locking money away longer. As of mid-2026, that relationship is unusually compressed. The top 1-year CD in REBOLST's database currently pays 4.00%. The top 3-year CD pays 3.70%. That's only a 0.30% difference across two additional years of commitment.
For a 3-year ladder, this is actually a favorable setup. You're capturing near-peak rates on all three rungs with very little spread between them. If the Federal Reserve continues its easing cycle and interest rates fall over the next two years — as futures markets were pricing in as of mid-2026 — then your 3-year rung will outperform the strategy of rolling 1-year CDs. You'll be locked in at today's rate while variable instruments drift lower.
The risk runs the other way if rates rise unexpectedly. But with a 3-year ladder, your exposure is manageable: one-third of your deposits are freed up each year to reinvest at whatever rate the market offers.
Does Your Deposit Size Affect Which Rate You Get?
It depends on the institution. The top online banks in REBOLST's database — Marcus by Goldman Sachs, Synchrony Bank, Capital One, and Ally Bank — offer flat CD rates regardless of deposit size. A $500 deposit earns the same APY as a $500,000 deposit at these institutions. This makes them straightforward for most savers building a standard 3-year ladder.
Some traditional banks and credit unions do tier their rates. A tiered structure typically looks like: standard rate for deposits under $10,000; slightly higher rate for $10,000–$99,999; and a jumbo rate for $100,000 and above. For example, data in REBOLST's database shows some institutions offering 0.15–0.25% more APY once your balance crosses the $100,000 threshold on certain CD terms.
If your per-rung deposit is above $10,000, it is worth checking both the top online banks and any regional banks or credit unions in your area. The tiered bump at a local institution occasionally exceeds what the major online banks offer, particularly for balances in the $50,000–$250,000 range. That said, the top online banks remain the most accessible starting point for most depositors building their first 3-year ladder.
If your deposit per rung exceeds $250,000, consider spreading across multiple institutions so every CD stays within FDIC or NCUA coverage limits. For a 3-rung ladder with large balances, using a different bank for each rung is a clean solution that also keeps your rates competitive across institutions.
3-Year Ladder vs. 5-Year Ladder: Which Is Right for You?
The 5-year CD ladder is the most commonly recommended version of this strategy, and with good reason: in a normal yield curve environment, 5-year CDs pay significantly more than 1-year or 3-year CDs, so once the ladder is fully built, you're locking in the best available fixed rate every year. But in the current flat-rate environment, the yield advantage of a 5-year ladder over a 3-year ladder is very small.
The meaningful difference is the timeline. A 3-year ladder reaches its "fully built" state in 3 years — when all rungs have cycled through once and every rung is a 3-year CD. A 5-year ladder takes 5 years to reach that state. If you're uncertain about committing to a 5-year horizon, or if you have a known need for access to a portion of these funds within 3–4 years, the 3-year ladder is the more appropriate tool.
One note: the 5-year CD in REBOLST's current database actually pays more than the 3-year CD at the top institutions (3.80% vs. 3.70% at Marcus by Goldman Sachs). If your goal is purely maximizing yield and you have the patience to build a longer ladder, that matters — and you should read the 5-year ladder guide before deciding.
When a CD Ladder Is NOT the Right Move
A 3-year CD ladder requires certainty: you need to be confident that you won't need the majority of this money for at least three years. If your situation doesn't allow for that — job uncertainty, health expenses, upcoming large purchases — a high-yield savings account offers full liquidity without penalty. The rate differential between the best HYSAs and the best short-term CDs is currently narrow enough that it may not be worth accepting the lock-up.
Similarly, if you're in a high tax bracket and this money is in a taxable account, consider that CD interest is taxed as ordinary income in the year it's credited — not when you withdraw. A tax-deferred wrapper like an IRA CD can change that calculus. Always consult a qualified tax advisor before making decisions based on after-tax return expectations.
Every CD charges an early withdrawal penalty — typically 6 to 12 months of interest for a 3-year term. If you exit a 3-year CD in the first year, you will almost certainly receive less than you deposited after the penalty is applied. Only put money in a CD ladder that you are genuinely prepared to leave untouched for the full term.
Tax Considerations for a 3-Year CD Ladder
CD interest is taxable as ordinary income in the year it's earned, regardless of when you withdraw. For a 3-year CD, banks typically credit interest annually — meaning you'll owe taxes each year on the interest earned, even though you can't access the money without penalty. In Year 3, you owe taxes on Year 3's interest plus any interest not yet reported from prior years, depending on how your bank structures crediting.
Holding CDs inside a Traditional IRA defers this tax liability until withdrawal. A Roth IRA eliminates the tax entirely on qualifying distributions. If you're building a ladder with after-tax money, the IRS 1099-INT form your bank sends each January covers what you owe. REBOLST does not provide tax advice — consult a qualified tax professional for guidance specific to your situation.
A 3-year CD ladder is the right strategy for savers who want competitive fixed rates, annual liquidity, and a manageable time horizon. In the current rate environment — with 1-year through 3-year CD rates clustered near 4.00% on the short end and 3.70% on the 3-year rung — building this ladder means locking in near-peak rates on every rung with minimal yield sacrifice between terms.
Open all three rungs at the same time, favor online banks that don't tier their rates (unless your balance is large enough to benefit from a jumbo rate), and reinvest every maturing CD in a new 3-year CD. The discipline is simple; the compounding effect over time is not.
Frequently Asked Questions
What is a 3-year CD ladder?
A 3-year CD ladder is a savings strategy where you divide your money into three equal parts and open a 1-year, 2-year, and 3-year CD simultaneously. Each CD matures one year apart. When each matures, you reinvest in a new 3-year CD. After the 3-year setup period, you have one 3-year CD maturing every 12 months — providing annual access to funds at a competitive fixed rate.
How much money do I need to start a 3-year CD ladder?
Many top online banks — including Capital One and Synchrony — offer CDs with no minimum deposit. Marcus by Goldman Sachs requires $500 per CD. A practical starting point is $3,000 or more (roughly $1,000 per rung), though there is no technical minimum at many institutions.
Is a 3-year CD ladder better than a 5-year CD ladder?
A 3-year ladder is simpler and reaches its fully-built state faster. A 5-year ladder eventually locks in longer-term rates — which in the current market (mid-2026) are actually slightly higher than 3-year rates at the top institutions. The right choice depends on your timeline: if you anticipate needing access within 3–4 years, the 3-year ladder is more appropriate.
What happens when a CD in my ladder matures?
You have a grace period — typically 7 to 10 days — to decide what to do. You can withdraw without penalty, reinvest in a new 3-year CD, or shift to a different term if rates have changed significantly. Missing the grace period typically triggers automatic renewal at the bank's current offered rate, which may be lower than what you originally opened at.
Should deposit size change which bank I use for each rung?
Possibly. The top online banks (Marcus, Synchrony, Capital One, Ally) do not tier their CD rates — same APY at any deposit size. Some traditional banks offer higher rates for balances above $10,000 or $100,000. If your deposit per rung exceeds $10,000, check both online and regional institutions before choosing.
Are CDs in a ladder FDIC insured?
Yes, at FDIC-member banks or NCUA-member credit unions, up to $250,000 per depositor, per ownership category, per institution. If total deposits at one institution exceed $250,000, consider spreading ladder rungs across multiple institutions to maintain full coverage.
