In the three-bucket retirement strategy, the bond bucket — bucket 2 — sits in the middle, and what belongs in it is straightforward: high-quality, intermediate-term bonds and bond-like holdings. Think Treasury notes, investment-grade corporate bonds, total-bond-market funds or ETFs, bond and CD ladders, inflation-protected Treasuries (TIPS), and medium-term CDs. The goal of this bucket is not maximum growth and not absolute safety — it is steady, lower-volatility income that refills your cash bucket while your stocks keep growing.
Get this bucket right and you create a reliable "engine" that feeds your spending money without forcing you to sell stocks at a bad time. Below we cover exactly what goes in it, why a bond ladder is its secret weapon, what to keep out, and where to hold it for tax efficiency. You can build and balance all three buckets in the RetireSpan retirement planner.
Structure all three buckets with confidence
RetireSpan helps you split your savings into cash, bonds, and stocks — and reminds you when to refill bucket 1 from bucket 2, so the whole system actually works. Download RetireSpan on the App Store or learn more on the RetireSpan landing page.
Bucket 2 covers roughly years 3 through 10 of your retirement. Its job is twofold: provide a stable, income-producing reserve that does not swing wildly with the stock market, and serve as the refill source for bucket 1 (your cash). When you spend down your cash, you replenish it from bucket 2 — and because bucket 2 is far more stable than stocks, you can do this without locking in big losses. That stability is the whole reason it exists, which you can see modeled in the app.
Here are the holdings that belong in bucket 2, what each is, and the role it plays.
| Holding | What It Is | Role in the Bucket |
|---|---|---|
| Treasury notes & bonds | U.S. government debt, 2–10 year terms | Safest core; backbone of the bucket |
| Investment-grade corporate bonds | High-quality company debt | A bit more yield than Treasuries |
| Bond funds & ETFs | Diversified baskets of bonds | Simple, diversified exposure |
| Bond or CD ladder | Bonds/CDs maturing in successive years | Built-in annual refill for bucket 1 |
| TIPS | Inflation-protected Treasuries | Guards purchasing power |
| Medium-term CDs | Bank deposits with a fixed term | Predictable, FDIC-insured income |
You do not need all of these — a simple intermediate bond fund or a bond ladder can stand on its own.
The common thread is quality and moderate maturity. Intermediate-term, high-grade holdings give you more return than cash without the gut-churning swings of stocks. You can see how different bond allocations affect your plan's stability in the RetireSpan tools.
A bond ladder is the most elegant way to run bucket 2. You buy bonds (or CDs or Treasuries) that mature in successive years — one in year 3, one in year 4, and so on. Each year, a rung matures and that cash flows down to refill bucket 1 automatically, with no need to sell anything early or worry about price swings.
This turns your bond bucket into a self-feeding system: maturities arrive on schedule, exactly when you need spending money. It also removes the temptation to time the market. Pairing a ladder with the refill reminders in the RetireSpan app means the cash always shows up where and when it should.
Tip: Match your bond maturities to when you will spend the money. A bond maturing in the year you need it carries virtually no interest-rate risk, because you simply hold it to maturity and collect the face value.
A pure-bond bucket has one quiet weakness: inflation can erode the value of fixed interest payments over time. That is where TIPS (Treasury Inflation-Protected Securities) earn their place — their principal adjusts with inflation, so a portion of your bond bucket keeps pace with rising prices. Holding some TIPS alongside conventional bonds is a sensible hedge for the middle bucket. You can factor an inflation assumption into your whole plan on the landing page.
Not everything labeled "fixed income" belongs here. High-yield ("junk") bonds carry more default risk and tend to fall alongside stocks in a downturn — defeating the bucket's stability purpose. Very long-dated bonds swing more with interest rates than intermediate ones, adding unwanted volatility. And stocks of any kind belong in bucket 3, not here. The bond bucket's job is calm reliability, so anything that behaves like the stock market undermines it. You can check that your allocation matches its intended role inside RetireSpan.
Bonds are relatively tax-inefficient, because their interest is generally taxed as ordinary income. When possible, hold taxable bonds in tax-advantaged accounts like a traditional IRA or 401(k), where that interest is not taxed each year. In a taxable brokerage account, higher-bracket retirees sometimes prefer municipal bonds, whose interest is often federally tax-exempt. Coordinating which assets sit in which accounts can meaningfully reduce your lifetime tax bill — a factor you can plan around in the app.
Build a bond bucket that does its job
RetireSpan helps you size and structure all three buckets, ladder your income, and refill cash at the right time — built for people 55–65 who want a clear, calm retirement income plan. Get it on the App Store or explore features on the RetireSpan website.
The bond bucket, or bucket 2, is the middle portion of the three-bucket strategy, typically covering years 3 through 10 of retirement. It holds high-quality, intermediate-term bonds and bond-like assets that provide steady income and stability, and it serves as the source for refilling your cash bucket. You can structure it in the RetireSpan planner.
High-quality, intermediate-term bonds are generally best for the retirement bond bucket: Treasury notes, investment-grade corporate bonds, TIPS for inflation protection, and CDs. These offer more return than cash with far less volatility than stocks. Lower-quality high-yield bonds are usually avoided because they behave more like stocks.
The bond bucket typically holds enough to cover roughly years 3 through 10 of your expenses — often around 30–40% of a retirement portfolio, though the exact figure depends on your spending, other income, and risk tolerance. The goal is enough to refill your cash bucket for several years without touching stocks. Your ideal split can be modeled in RetireSpan.
A bond ladder is a set of bonds or CDs that mature in successive years, so a portion comes due each year to fund your spending. It provides a predictable stream of cash to refill bucket 1 and removes interest-rate risk on bonds held to maturity. Many retirees consider it the ideal structure for the bond bucket.
Both work. Individual bonds and ladders offer predictable maturity dates and known payouts, which suits the refill role well. Bond funds and ETFs offer instant diversification and simplicity but fluctuate in price and have no fixed maturity. Many retirees use a mix, or choose based on how hands-on they want to be.
Yes, TIPS are a useful addition because their principal adjusts with inflation, helping the bond bucket keep pace with rising prices over time. Holding some TIPS alongside conventional bonds hedges the one weakness of fixed-income holdings. They are especially valuable for retirees worried about long-term purchasing power.
