Compare a Treasury’s yield with inflation over the same period you expect to hold it. For an estimate of a nominal Treasury’s purchasing-power return, use (1 + nominal yield) / (1 + inflation rate) − 1. For a market-based comparison, pair a nominal Treasury with a TIPS issue of the same maturity and compare the nominal yield with the TIPS real yield. Then account for taxes, liquidity, reinvestment risk and whether you need inflation-adjusted principal at maturity.
A quoted yield is not automatically your return. TreasuryDirect defines yield to maturity as the annual rate of return, but that measure assumes you hold the security to maturity and reinvest interim cash flows at the assumed rate. A mismatch between maturity, holding period or inflation measure can make an apparently attractive investment misleading.

What you are actually comparing
A nominal Treasury bill, note or bond promises fixed dollar cash flows. Its coupon and maturity value do not rise when consumer prices rise. If inflation is higher than expected, those fixed dollars buy less.

Interest is calculated on the adjusted principal, so the dollar coupon payment can rise or fall even though the coupon rate itself is fixed. The useful comparison is therefore purchasing-power return, not just the largest quoted percentage.

Three concepts should be kept separate:
- Nominal yield: the annualized return stated in current dollars.
- Inflation rate: the rate at which the general price level rises, commonly measured in the United States with CPI-U.
- Real yield or return: the return after allowing for changes in purchasing power.
Use a maturity that matches your planned holding period. Comparing a two-year Treasury yield with a 10-year TIPS yield mixes different inflation expectations, interest-rate risk and reinvestment assumptions.
Calculate a nominal Treasury’s estimated real return
For a quick estimate, convert the nominal yield and an inflation assumption into a real return with:
real return = (1 + nominal yield) / (1 + inflation rate) − 1

Do not simply subtract inflation when accuracy matters. Subtraction is a rough shortcut; the formula compounds both rates.
Worked example
Suppose a Treasury has a 4.50% annual yield and you expect inflation of 3.00% over the holding period:
(1.045 / 1.030) − 1 = 0.01456
The estimated real return is about 1.46% per year before taxes, fees and any sale-price change. If inflation instead averages 6.00%, the same nominal yield produces:

(1.045 / 1.060) − 1 = −0.01415
That is an estimated real loss of about 1.42% per year. The Treasury can still pay every dollar promised while your purchasing power declines.
What the estimate leaves out
- Inflation may vary from your assumption, and your personal spending basket may differ from CPI-U.
- Selling before maturity exposes you to a market price gain or loss as interest rates change.
- Coupons and maturities may need to be reinvested at unknown future rates.
- Federal tax can reduce the after-tax real return.
Use the calculation as a planning estimate, not as a guaranteed outcome.
Use same-maturity nominal Treasuries and TIPS for a market comparison
A nominal Treasury yield and a same-maturity TIPS real yield provide a market-implied inflation comparison. For example, pairing a 10-year nominal Treasury with a 10-year TIPS avoids comparing different interest-rate horizons.
A simplified breakeven calculation is:
breakeven inflation ≈ nominal Treasury yield − TIPS real yield
For greater mathematical consistency, use:
breakeven inflation = (1 + nominal yield) / (1 + TIPS real yield) − 1

Illustrative comparison
| Security | Yield assumption | Role in comparison |
|---|---|---|
| 10-year nominal Treasury | 4.50% | Fixed-dollar return |
| 10-year TIPS | 1.50% real yield | Inflation-adjusted return |
| Approximate breakeven | About 2.96% using the compounded formula | Market-implied inflation rate, not a guarantee |
If you expect inflation above the breakeven rate and value inflation-linked principal, TIPS may be more suitable. If you expect inflation below it and prefer fixed cash flows, the nominal Treasury may offer the better expected result. Your taxes, liquidity needs and risk tolerance can reverse that conclusion.
A repeatable comparison process
- Define the objective. Decide whether you need a known dollar amount, protection of future purchasing power, income during the holding period or a liquid reserve.
- Set the holding period. Choose the date when you expect to spend the money. A security that matures after that date may have to be sold at an uncertain price.
- Choose comparable securities. Select a nominal bill, note or bond and, when available, a TIPS with a matching maturity. TIPS are issued in 5-, 10- and 30-year terms.
- Record the inputs. Write down the nominal yield, TIPS real yield if applicable, the latest CPI-based inflation reading or your own inflation assumption, purchase price, maturity date and account type.
- Compute the estimate. Apply
(1 + nominal yield) / (1 + inflation) − 1to the nominal security. For a market comparison, calculate the nominal-versus-TIPS breakeven. - Model more than one inflation path. Test low, central and high inflation assumptions. A single forecast creates false precision.
- Check taxes. Include federal tax and the treatment of inflation adjustments. TreasuryDirect states that TIPS and Series I Bond earnings are exempt from state and local income taxes, but federal taxation still applies.
- Check liquidity and reinvestment. Confirm whether you can sell, when you can redeem, what penalty applies and where coupons or maturities will be reinvested.
- Decide whether maturity principal matters. TIPS repay the original or inflation-adjusted principal, whichever is greater, at maturity. That feature may matter more than a small difference in quoted yield.
How nominal Treasury bills, notes and bonds behave
Nominal Treasuries keep their principal terms fixed. A Treasury bill is a short-term instrument issued at a discount and paid at face value at maturity. Notes and bonds pay scheduled interest, with maturity terms that can extend for years or decades. Regardless of format, the key inflation risk is the same: the dollars are fixed.
Holding to maturity
If you hold a nominal Treasury to maturity and the issuer pays as promised, you know the dollar cash flows in advance. Your real result still depends on the inflation that occurs between purchase and maturity. A 4% yield does not mean a 4% increase in purchasing power.
What’s actually slowing this PC down?

Selling before maturity
Market prices generally move opposite prevailing interest rates. If rates rise after you buy, your security may be worth less than you paid; if rates fall, it may be worth more. The price change can dominate the coupon return over a short holding period. Match maturity to the date you need the money when avoiding sale-price uncertainty is important.
Reinvestment risk
Coupon payments and proceeds from maturing short-term bills must be reinvested. If future rates are lower, the return on those cash flows will be lower than the original quoted yield. A yield-to-maturity figure assumes a reinvestment rate for interim payments; your realized return can differ.
How TIPS adjust for inflation
TIPS are issued in 5-, 10- and 30-year terms. TreasuryDirect states that purchases start at $100. Their principal is linked to the non-seasonally adjusted U.S. City Average All Items CPI-U published by the Bureau of Labor Statistics.

Indexing and coupon payments
TreasuryDirect’s calculation method is:
- Multiply the original principal by the applicable CPI-U index ratio to obtain adjusted principal.
- Multiply adjusted principal by half the stated annual coupon rate to calculate a semiannual interest payment.
Because the coupon is applied to adjusted principal, the dollar payment rises when the indexed principal rises and falls when it declines. Interest is paid every six months.
Deflation and the maturity floor
TreasuryDirect explains that “The principal of a TIPS goes up and down with inflation and deflation.” At maturity, however, you receive either the increased inflation-adjusted principal or the original principal, whichever is greater. This protects the maturity principal from falling below the amount originally invested, assuming you hold the security to maturity. It does not prevent a market-price loss if you sell earlier.
Real yields can be negative
Treasury TIPS auction rules allow negative real-yield bids. A negative real yield means the security’s return, after its inflation adjustment, is expected to be below zero before taxes and other costs. Inflation protection does not guarantee a positive real return; it changes how the return responds to CPI-U.
TIPS compared with nominal Treasuries
| Factor | Nominal Treasury | TIPS |
|---|---|---|
| Cash-flow basis | Fixed dollar principal and scheduled interest | Fixed coupon rate applied to inflation-adjusted principal |
| Inflation exposure | Unexpected inflation reduces purchasing power | Principal and interest adjust with CPI-U |
| Terms highlighted by TreasuryDirect | Varies by bill, note and bond issuance | 5, 10 and 30 years |
| Minimum purchase stated by TreasuryDirect | Depends on the security and purchase channel | $100 |
| Maturity principal | Fixed face value | Original or inflation-adjusted principal, whichever is greater |
| Early sale | Marketable; price depends on rates and market conditions | Marketable; price depends on real rates, inflation expectations and market conditions |
| Federal tax treatment | Interest is federally taxable | Interest and inflation adjustments are federally taxable as they occur |
| State and local income tax | Treasury interest is generally exempt under federal law | TreasuryDirect states TIPS earnings are exempt from state and local income taxes |
The tax treatment of TIPS creates a potential “phantom income” issue: an inflation adjustment can be taxable federally even though you do not receive that adjustment in cash until later. Holding TIPS in an account suited to your tax situation can therefore matter as much as the quoted real yield.

Series I Bonds also use an inflation-linked return, but they are not interchangeable with TIPS. TIPS are marketable securities bought at auction or through banks, brokers and dealers. Series I Bonds are non-marketable and purchased through TreasuryDirect.

For bonds issued from May 1 through October 31, 2026, TreasuryDirect lists a 4.26% composite I Bond rate, consisting of a 0.90% fixed rate and a 3.34% annualized inflation rate. This is a six-month rate window and should be rechecked after the next rate announcement. It is not a directly comparable “real yield” quote because the composite formula combines a fixed component and an inflation component, and the rate changes for new issues over time.
Taxes can change the ranking
Compare investments on an after-tax basis when they will be held in a taxable account. Nominal Treasury interest is federally taxable, while TreasuryDirect states that TIPS and I Bond earnings are exempt from state and local income taxes. TIPS inflation adjustments and interest are federally taxable as they occur, even when the adjustment is not yet paid out as cash.
The same nominal yield can produce different real spending power for investors in different federal tax brackets. A tax-deferred or tax-exempt account may change the effect of annual TIPS adjustments, but account rules, withdrawal taxes and penalties still apply. Do not assume that a tax label makes one security universally superior.
Match the investment to the money’s job
Money needed on a known date
Use a maturity date close to the spending date if certainty of principal is the priority. A nominal Treasury provides a known dollar amount; a TIPS provides protection against CPI-U changes and a maturity principal floor. Selling either type early introduces market-price risk.

Long-term purchasing-power protection
TIPS are designed for investors who want principal and interest to respond to CPI-U. Evaluate the quoted real yield, not just the inflation adjustment. A negative real yield can still be acceptable if avoiding unexpected inflation is more important than maximizing the stated real return.
Short-term inflation hedge with limited access
Series I Bonds can suit money that can remain unavailable for at least 12 months and may stay invested for five years or more to avoid the early-redemption penalty. The $10,000 annual electronic purchase limit constrains how much can be allocated through that channel.
Flexible trading or laddering
Marketable Treasuries and TIPS allow a secondary-market sale and can be arranged in a maturity ladder. The trade-off is that the sale price is not guaranteed. Build the ladder around actual cash-flow dates rather than selecting the highest isolated yield.
Common comparison mistakes
- Mixing maturities: A 10-year nominal yield versus a five-year TIPS yield is not a clean inflation comparison.
- Using current inflation as a promise: A recent CPI reading describes the past or present measurement period; it does not establish future inflation.
- Subtracting rates without qualification: Nominal yield minus inflation is only an approximation. Use the compounded formula for planning.
- Ignoring sale risk: A yield-to-maturity number does not protect you from a loss if you sell before maturity.
- Ignoring taxes on TIPS adjustments: Federal tax can arise before the inflation-adjusted principal is received.
- Treating a TIPS real yield as guaranteed purchasing power: The quoted real yield is tied to holding assumptions, and realized results can differ.
- Assuming inflation protection means positive returns: TIPS real yields can be negative.
- Overlooking access rules: I Bonds cannot be redeemed during the first 12 months and incur a three-month interest penalty before five years.
- Using stale inputs: Auction yields, CPI readings, I Bond rates, purchase limits, redemption rules and tax guidance change.
A practical decision checklist
Before purchasing, write down:
- The exact date the money may be needed.
- The security’s maturity and whether you will hold it to maturity.
- The nominal yield, TIPS real yield or I Bond composite rate and the date each was observed.
- Your low, central and high inflation assumptions.
- The estimated real return under each assumption.
- Federal, state and local tax effects in the account you will use.
- How coupons, inflation adjustments or maturity proceeds will be reinvested.
- Whether you can tolerate a market loss if you must sell early.
- Whether inflation-adjusted principal at maturity is more important than a higher nominal yield.
Refresh every time-sensitive input immediately before an investment decision. The 4.26% I Bond composite rate cited above applies only to bonds issued May 1–October 31, 2026; future six-month rates may be different.
Bottom-line framework
Start with the holding period, then compare like maturities. Estimate a nominal Treasury’s real return with (1 + nominal yield) / (1 + inflation) − 1. Compare a nominal yield with the same-maturity TIPS real yield to see the market-implied inflation spread, while remembering that liquidity, taxes and risk premiums distort that spread. Choose nominal Treasuries for predictable dollar cash flows, TIPS when CPI-U-linked purchasing power and a maturity principal floor are central, and Series I Bonds only when their access limits and redemption rules fit your plan.
