A bond ladder is a portfolio of individual bonds with staggered maturity dates. Each year, one rung matures and returns principal; you either spend it or roll it into a new bond at the long end of the ladder. The structure produces predictable cash flow, eliminates interest-rate risk if held to maturity, and is conceptually simple.
Why ladders, why now
For 15 years prior to 2022, low interest rates made bond ladders barely worth the effort. With Treasuries yielding 4–5% in 2024–2026, ladders are once again a serious tool for retirees seeking known nominal income with minimal complexity.
The three flavors of ladder
- Treasury ladder: US Treasuries, often 5–10 rungs. Default-risk-free, state-tax-exempt, simple. Best baseline.
- TIPS ladder: Treasury Inflation-Protected Securities. Principal adjusts with CPI. Used heavily in "liability-matching" retirement strategies (LMP) popularized by Zvi Bodie and refined by TIPSLadder.com.
- Corporate ladder: Investment-grade corporates yield more than Treasuries (typically +100 bps) but carry credit risk. Best as a supplement, not the core.
Building one in practice
Most major brokerages (Fidelity, Schwab, Vanguard) let you buy individual Treasuries directly with no commission, in $1,000 increments. The build process:
- Decide ladder length (typically 5–10 years for retirees).
- Decide total dollar amount (e.g., 5–10 years of expenses).
- Divide evenly across maturities.
- At each year-end, the matured rung is replaced with a new longest-maturity bond, keeping the ladder rolling.
Ladder vs. bond ETF
Many retirees ask whether a bond ETF (BND, AGG, VGIT) achieves the same thing. They're similar but not identical:
- ETFs trade at NAV that fluctuates with rates. If rates rise, the ETF's market price falls. A held-to-maturity individual bond returns par regardless.
- ETFs deliver income forever; ladders deliver principal back. ETFs never "mature" in your account.
- ETFs are simpler. One ticker, automatic reinvestment, no thinking.
- Ladders give psychological certainty. "My 2028 rung will pay me $50k in 2028" — that statement is mathematically guaranteed.
For most retirees with modest portfolios, BND or VGIT is the easier choice. Ladders earn their complexity when total bond holdings exceed roughly $250,000 and the retiree values cash-flow precision.
Worked example — TIPS ladder for inflation protection
A 65-year-old with $1M in fixed income wants 25 years of inflation-protected income at $40,000/year (real). The TIPSLadder.com tool can construct a portfolio of TIPS maturing every year from 2027 through 2051. Roughly $30,000 of TIPS purchased per maturity year (varies by current real yield) produces the cash flow.
This is "liability matching" — assets engineered to exactly cover the spending stream, removing both inflation and sequence risk for the basic income need.
Common mistakes
- Reaching for yield via corporate or junk bonds. The extra 100–300 bps comes with default risk that can hit at the worst time. Stay investment-grade.
- Ignoring callable bonds. Some agency and corporate bonds can be called away by the issuer if rates fall. Read the prospectus.
- Buying brokered CDs without checking the issuer. Brokered CDs are FDIC-insured up to $250k per bank per depositor. Confirm the issuing bank's status.
- Selling before maturity. The whole point of a ladder is to avoid mark-to-market losses. If you sell early, you've defeated the design.
FAQs
How often should I rebalance?
Once a year, after the matured rung's principal is returned. Either spend it or buy a new long-end bond.
Can I do this in an IRA?
Yes — and it's tax-efficient because bond interest is shielded inside the IRA.
Where do I actually buy these?
Fidelity's "Fixed Income" tab and Schwab's "Bond Source" both let retail investors buy individual Treasuries at auction or on the secondary market with zero commissions.
