A TIPS ladder is a portfolio of Treasury Inflation-Protected Securities bought with staggered maturity dates so that one bond comes due each year, delivering a predictable stream of inflation-adjusted cash across a set period. Retirees and anyone funding a known sequence of future expenses use the structure to lock in real spending power without betting on where interest rates or inflation will land in any single year.
How TIPS Work
TIPS are bonds issued by the U.S. Treasury whose face value rises and falls with the Consumer Price Index for All Urban Consumers (CPI-U), the non-seasonally adjusted measure published monthly by the Bureau of Labor Statistics.1TreasuryDirect. TIPS/CPI Data A conventional Treasury pays back a fixed dollar amount; a TIPS pays back principal that has been marked up (or down) to reflect actual inflation. If prices rise 3% over a year, the principal rises roughly 3% too.
The coupon rate is set at auction and never changes, but because that fixed rate is applied to the adjusted principal, each semiannual interest payment grows as inflation pushes the principal higher. At maturity, you receive the greater of the inflation-adjusted principal or the original face value.2TreasuryDirect. Treasury Inflation-Protected Securities (TIPS) That floor guarantee means a prolonged deflationary stretch cannot cut into what you originally paid. The Treasury currently issues TIPS in 5-year, 10-year, and 30-year maturities.3TreasuryDirect. Understanding Pricing
Why Stagger the Maturities
Laddering means spreading your money across multiple TIPS that mature in different years. If you need inflation-protected income for 20 years, you buy bonds maturing in years one through twenty. Each maturity is a rung. When a rung matures, you spend that principal or, if you want to keep the ladder going, reinvest it into a new long-dated TIPS at the far end.
The core advantage is that you never reinvest the whole portfolio at once. If real yields are low the year a rung matures, only that single year’s tranche is exposed to the unfavorable rate. The remaining rungs keep earning whatever real yield they locked in at purchase. A lump sum in a single TIPS maturity turns into a binary bet on where rates sit on one specific day.
A ladder also removes the guesswork around selling bonds before maturity. Because you hold each bond to its maturity date, the market price along the way doesn’t affect you. You collect the inflation-adjusted principal at the end, and that is the number you planned around. The hold-to-maturity discipline is what makes the strategy genuinely low-risk rather than just theoretically low-risk.
Building a TIPS Ladder
Set Your Annual Real-Income Target
Start with how much inflation-adjusted income you need each year. Most people building a ladder are covering a specific spending gap, such as the years between early retirement and when Social Security begins. If you need $40,000 per year in today’s dollars for 30 years, that is your target per rung.
Choose the Spacing
Annual rungs give the smoothest cash flow. Biennial spacing (a bond every two years) halves the number of bonds you have to manage, but each maturing bond has to fund two years of spending. For most ladders covering 10 to 30 years, annual spacing is simple enough to be worth it.
Plan Around Gap Years
The Treasury does not issue a new TIPS for every calendar year, so a limited number of distinct maturity dates exist at any given time. For years where no TIPS matures, you either use a bond maturing in a nearby year and sell part of it on the secondary market, or hold excess cash from an adjacent rung. One published example of a 30-year ladder found that some bonds had to cover two or three years of spending because no TIPS existed for certain maturity dates in between. Expect this. It is a real-world limit on the clean version of the strategy.
Buy the Bonds
TIPS are sold in $100 increments with a $100 minimum.2TreasuryDirect. Treasury Inflation-Protected Securities (TIPS) You can buy directly from the Treasury at auction through TreasuryDirect.gov, or through a brokerage account that offers both new-issue auctions and the secondary market. TreasuryDirect charges no trading fees, but the interface is clunky and you cannot sell bonds before maturity through the platform. A brokerage gives you the flexibility to buy older TIPS on the secondary market to fill specific maturity gaps, which is often necessary for a full ladder.
Because each rung must be purchased in $100 blocks, the cash flow from each year’s maturing bond will not be identical. For a $40,000 target, you may end up with rungs paying $39,900 or $40,100 depending on rounding. The variation is trivial.
Real Yields and What You’re Paying for the Certainty
Before committing, look at two numbers: the real yield and the breakeven inflation rate. The real yield is what TIPS pay above inflation. When it is meaningfully positive, TIPS are offering genuine compensation for lending your money. When it is negative, as it was for stretches of 2020 through 2022, you are paying for the privilege of inflation protection and your return after inflation is negative.
The breakeven inflation rate is the gap between a nominal Treasury yield and the TIPS real yield for the same maturity. It represents the inflation rate at which both investments produce the same return.4Federal Reserve Bank of San Francisco. TIPS Liquidity, Breakeven Inflation, and Inflation Expectations If the 10-year nominal Treasury yields 4.5% and the 10-year TIPS yields 2%, the breakeven is 2.5%. You come out ahead with TIPS only if inflation over that decade averages above 2.5%.
For a ladder, this matters less than it might seem. The point is guaranteed inflation-adjusted spending, not outperforming nominal Treasuries. You are buying certainty. Still, checking real yields tells you the price of that certainty. Positive real yields make it cheap. Negative real yields make it expensive, and building the ladder gradually over months or years rather than all at once helps avoid committing everything at a bad entry point.
Ladder vs. TIPS Fund vs. Target-Maturity ETF
A broad TIPS mutual fund or ETF holds bonds across many maturities and constantly buys and sells as bonds mature and new ones are issued. If you need to withdraw in a given year, you are selling shares at whatever the market price happens to be. If real rates have risen since the fund’s bonds were purchased, TIPS prices have fallen and you may sell at a loss large enough to offset the inflation protection you were counting on. An individual ladder avoids this because you hold each bond to maturity and collect the full adjusted principal.
The usual advantages of bond funds barely apply to a ladder investor. Diversification adds nothing when every holding is a U.S. Treasury with the same credit quality. Liquidity is a secondary concern when you never plan to sell early. Credit monitoring is irrelevant when the borrower is the federal government.
Target-maturity TIPS ETFs are a middle ground. Each fund holds TIPS maturing in a single target year and distributes its net asset value to shareholders in that year, mimicking an individual bond’s payout. You can build a ladder from a series of these funds. The trade-off is a small annual expense ratio that an individual bond does not carry, in exchange for professional management of coupon reinvestment and easier purchasing in smaller amounts.
Taxes and Where to Hold the Ladder
The biggest tax wrinkle with TIPS is phantom income. Each year, the inflation adjustment to your bond’s principal counts as taxable income even though you receive no cash from it until the bond matures. The IRS classifies the adjustment as original issue discount and requires you to include it in gross income for the year it accrues.5Internal Revenue Service. Publication 1212 – Guide to Original Issue Discount (OID) Instruments
If you own $100,000 in TIPS and inflation runs at 3%, your principal grows by about $3,000 and you owe federal income tax on that $3,000 even though the money is still locked inside the bond. The semiannual coupon payments you actually receive are taxed as ordinary income too. Both the coupon and the phantom income are exempt from state and local income taxes, like interest on any other U.S. Treasury obligation.6Office of the Law Revision Counsel. 31 USC 3124 – Exemption From Taxation
That combination makes TIPS a poor fit for taxable brokerage accounts, because you end up writing checks to the IRS for income you cannot yet spend. Inside a traditional IRA, taxes on both the coupon and the inflation adjustment defer until withdrawal. Inside a Roth IRA, they are eliminated. Most advisors recommend putting a TIPS ladder in a retirement account whenever possible.
Risks and Limits
Selling Before Maturity
Hold every bond to maturity and market price swings do not touch you. Sell a rung early and you take on real interest rate risk: if prevailing real yields have risen above your bond’s coupon, its price has dropped. TIPS bid-ask spreads are wider than those on nominal Treasuries, and older “seasoned” TIPS are notably less liquid than recently issued ones.7Federal Reserve Bank of San Francisco. TIPS Liquidity and Breakeven Inflation Selling an older TIPS mid-ladder can mean accepting a meaningfully worse price than you would on a regular Treasury.
Negative Real Yields
The ladder does not override bad entry prices; it just spreads them out. When real yields are negative at purchase, you are locking in a guaranteed loss of purchasing power even after the inflation adjustments do their job.
Gap Years
Because no TIPS matures in every calendar year, a long ladder will contain stretches where one bond funds two or three years of spending. Some years produce slightly more or less than your target. Manageable, but the smooth annual-payment version is a textbook idealization.
Inflation Measure Mismatch
TIPS track CPI-U, which reflects average urban consumer spending.1TreasuryDirect. TIPS/CPI Data Your personal inflation rate may differ if your biggest expenses are in categories like healthcare or housing, which often outpace overall CPI. A retiree whose spending is dominated by medical costs may find that TIPS adjustments lag the actual erosion of purchasing power. The protection is real but imperfect.
Why I Bonds Aren’t a Substitute
Series I savings bonds also adjust for inflation, but they cannot replace a TIPS ladder for retirement spending. I Bonds have a $10,000 annual purchase limit per Social Security number, so building a meaningful multi-year ladder around them is impractical.8TreasuryDirect. Comparing TIPS to I Bonds They also cannot be sold on a secondary market: they are redeemable after 12 months with a three-month interest penalty, and penalty-free only after five years. For small supplemental inflation protection, I Bonds work well. For a structured multi-year income plan, TIPS are the only realistic option.
