CD Ladder for Retirement Income

When you retire, a portion of your portfolio needs to be reliable. Equities grow over time but can drop 30–40% in a bad year. A CD ladder converts a slice of your savings into predictable annual income — at rates that, as of mid-2026, still sit well above the long-run average.

This guide explains how CD ladders work, how to size and build one, where they fit in your overall retirement income plan, and what the tax and IRMAA implications are. Start with the calculator, then read the strategy sections that apply to your situation.

Why CD ladders work for retirees

A CD ladder addresses two problems that make retirement income planning hard:

• Sequence-of-returns risk. If you hold 100% equities and the market drops 35% in year 2 of retirement, selling shares to cover expenses locks in permanent losses. A CD ladder creates 1–5 years of guaranteed spending without touching your equity portfolio during a downturn.
• Reinvestment-rate risk. Holding all cash in a single 5-year CD locks in today's rate, but rates may be higher in 2 years. Laddering means you're reinvesting one rung per year, capturing a blend of future rates rather than betting on a single point in time.

As of June 2026, top 1-year CD rates sit around 4.10% APY (Bankrate).¹ That's significantly above the 10-year average and makes the case for CDs stronger than it was in 2020–2021.

How a CD ladder works

You divide your fixed-income allocation into equal portions across multiple CDs, each maturing one year later than the last. With a 5-rung ladder, $500,000 becomes five $100,000 CDs maturing in 2027, 2028, 2029, 2030, and 2031.

Each year, one CD matures. You can:

• Spend the proceeds — if you need the principal for living expenses that year.
• Reinvest at the longest rung — roll the maturing CD into a new 5-year CD, maintaining the ladder indefinitely.
• Partially spend, partially reinvest — the most common approach.

The annual interest payments — which arrive throughout the year depending on how you structure the CDs — function as a second income stream alongside Social Security and any pension.

Step-by-step: building your ladder

1. Decide how much to ladder. Conventional guidance: enough to cover 2–5 years of essential expenses (not total spending — just housing, healthcare, food). This is your "bucket 2" allocation in the three-bucket strategy. For a retiree spending $60,000/year with $36,000 in essential expenses, a 5-rung ladder of $150,000–$180,000 covers bucket 2 entirely.
2. Compare rates. Check Bankrate, NerdWallet, and DepositAccounts to find the highest-yielding CDs for each term (1yr through 5yr). Top online banks and credit unions typically offer 50–150 basis points more than national bank averages. Update the default rates in the calculator above to reflect current offers.
3. Watch FDIC limits. FDIC insurance is $250,000 per depositor, per institution, per account category — for individual accounts, $250K per bank. Joint accounts get $500K per bank.² If your ladder exceeds $250K, spread it across multiple banks — or use brokered CDs (see below).
4. Open the CDs. Online banks and credit unions let you open CDs in minutes. Choose "interest paid at maturity" (most common) or "interest paid monthly/annually" if you want regular cash flow during the term.
5. Record the maturity dates. Set calendar reminders 30–45 days before each CD matures. This gives you time to decide whether to reinvest or spend, and to line up the next CD at the best available rate.

Brokered CDs vs. bank CDs

You can buy CDs through a brokerage account (Fidelity, Schwab, Vanguard) as well as directly from banks. The tradeoffs:

For most retirees building a straightforward ladder, direct bank CDs are simpler and predictable. Brokered CDs are worth considering if you want more flexibility or if you're managing a large ladder inside a brokerage IRA.

Tax treatment and IRMAA interaction

CD interest is ordinary income — taxed at your marginal federal rate (10%–37%), not the lower capital gains rate. This is different from qualified dividends or long-term capital gains, and it matters for retirees managing their IRMAA exposure and Social Security combined income threshold.

IRMAA cliff watch: In 2026, the first IRMAA surcharge threshold is $109,000 for single filers and $218,000 for married filing jointly.³ A $400,000 CD ladder at 4% generates $16,000 in annual interest — by itself, unlikely to trigger IRMAA. But combined with Social Security, pension, RMDs, and other investment income, that interest can tip you into the next tier. Run the IRMAA calculator with your CD interest included in your income estimate.

Social Security taxation: CD interest from taxable accounts counts toward the combined income test (IRC § 86). If your combined income (AGI + nontaxable SS + half of SS benefits) exceeds $25,000 single / $32,000 MFJ, up to 50% of SS becomes taxable — and above $34,000 / $44,000, up to 85% is taxable. Large taxable CD ladders can deepen the SS income torpedo.⁴

CD ladder vs. alternatives

For most retirees, a CD ladder complements rather than replaces these alternatives. A common structure: money market fund for 1-year bucket, 5-year CD ladder for years 2–6, TIPS or I-bonds for inflation hedge, equities for long-term growth.

CD ladders and the three-bucket strategy

The three-bucket strategy assigns different assets to different time horizons. CD ladders fit naturally into Bucket 2 — the intermediate bucket covering years 3–7 of retirement spending:

• Bucket 1 (now): 1–2 years of essential spending in cash or money market. No CD needed here — you want same-day liquidity.
• Bucket 2 (years 3–7): CDs, intermediate-term bonds, or TIPS. A 5-rung CD ladder sits here perfectly — each rung matures sequentially to refill bucket 1 as it depletes.
• Bucket 3 (8+ years): Growth assets — equities, real estate investment trusts, dividend funds. Time horizon is long enough to ride out market downturns.

The ladder's real value: if equities drop in year 1 of retirement, you're spending from Bucket 1 (cash) and then Bucket 2 (maturing CDs) — you never have to sell equities at a loss. Learn more in the three-bucket strategy guide.

Limitations to know before you build

• No inflation protection. A $500,000 ladder generating $20,000/year in interest produces the same $20,000 in year 5, even if inflation has reduced its purchasing power. Over 25 years of retirement, inflation is the silent risk that CDs don't hedge. Keep the majority of your portfolio in inflation-sensitive assets (equities, TIPS, I-bonds, real estate).
• Early withdrawal penalties. Most bank CDs charge 3–6 months of interest if you break a CD before maturity. This is workable for occasional liquidity needs — but if you might need the full balance in a year, a money market fund or T-bills is a better fit.
• Reinvestment risk. When a CD matures and rates have fallen, you roll into a lower rate. This is the tradeoff for not locking in long-term rates entirely — you can capture rate increases too, but you're also exposed to rate decreases on the short rungs.
• Not a growth vehicle. A 4% CD return is below the long-run stock market average (~7% real). This is intentional — CDs serve the stability function in your portfolio. Sizing the ladder too large (say, 60%+ of portfolio) sacrifices too much long-term purchasing power.

When a financial advisor adds value here

Building a CD ladder is straightforward, but optimizing it within your full retirement income plan is not. A retirement income specialist can help you:

• Size the ladder relative to your SS, pension, RMDs, and equity allocation
• Decide how much goes in taxable vs. Roth IRA CDs to minimize IRMAA exposure
• Coordinate CD maturity dates with your RMD schedule and planned Roth conversions
• Evaluate whether a CD ladder, TIPS ladder, or SPIA better fits your longevity risk tolerance
