Breakeven Formula
Calculation Results
Your inflation expectation matches the breakeven rate.
Formula Breakdown
Decision Guide
| Your Expectation vs Breakeven | Recommendation |
|---|---|
| Your inflation > Breakeven + 0.05% | TIPS Favored |
| Your inflation < Breakeven - 0.05% | Nominals Favored |
| Within 0.05% of Breakeven | Neutral |
Model Assumptions
- Uses market-convention quoted breakeven (spread approximation, not exact Fisher equation)
- Requires same-maturity nominal Treasury and TIPS yields for valid comparison
- Assumes hold-to-maturity strategy and pre-tax analysis
- TIPS are indexed to CPI-U, which may differ from your personal inflation experience
- Breakeven includes liquidity and inflation-risk premia beyond pure inflation expectations
- Does not account for the TIPS deflation floor (principal protected at par)

Understanding TIPS Breakeven Inflation
What is TIPS Breakeven Inflation?
TIPS breakeven inflation is the difference between a nominal Treasury yield and a TIPS (Treasury Inflation-Protected Securities) real yield of the same maturity. It represents the market-implied inflation compensation - the inflation rate at which an investor would be approximately indifferent between holding TIPS or nominal Treasuries.
This is the market-convention "quoted breakeven" used by traders and analysts
TIPS vs Nominal Treasuries
TIPS
Inflation Protection
Principal adjusts with CPI-U. Real yield is guaranteed if held to maturity. Outperform if actual inflation exceeds breakeven.
Nominal Treasuries
Fixed Coupon
Known nominal return at purchase. Real return depends on actual inflation. Outperform if actual inflation is below breakeven.
Making the Decision
The decision between TIPS and nominal Treasuries depends on whether you expect inflation to be higher or lower than the market-implied breakeven:
- If your expected inflation > breakeven: TIPS are favored because you expect more inflation protection than the market has priced in.
- If your expected inflation < breakeven: Nominal Treasuries are favored because you don't need to pay for inflation protection you don't expect to use.
- If expectations match: You're approximately indifferent (other factors like liquidity and taxes may tip the decision).
Key Considerations
- CPI-U linkage: TIPS are indexed to the Consumer Price Index for All Urban Consumers, which may differ from your personal inflation experience
- Liquidity premium: TIPS typically trade with less liquidity than nominal Treasuries, which can affect breakeven levels
- Tax treatment: TIPS inflation adjustments are taxed as income in the year they occur, even though you don't receive the cash until maturity
- Deflation floor: TIPS principal is protected at par - you won't receive less than the original face value at maturity even in deflation
