How this tips vs treasury breakeven inflation calculator works

The simple breakeven is nominal yield minus real yield. The scenario compounds the nominal security at its yield and the TIPS principal at the real yield plus the entered inflation path.

Formula

Breakeven inflation ≈ nominal Treasury yield − TIPS real yield

Actual TIPS cash flows adjust with CPI and include indexation lags. Market breakevens also contain inflation-risk and liquidity premiums.

Frequently asked questions

Is breakeven inflation a forecast?

Not exactly. It reflects market pricing plus inflation-risk, liquidity, and technical premiums.

Can TIPS lose money?

Yes. Real yields can rise, market prices can fall, and selling before maturity can realize a loss.

How are TIPS taxed?

US federal taxation can include coupon income and inflation adjustments, including adjustments not received in cash until maturity. Tax treatment depends on the account and investor.
