# TIPS Yield > An independent educational reference for U.S. Treasury Inflation-Protected Securities (TIPS), featuring a free TIPS ladder calculator, real-yield history, and guides to buying, taxes, and retirement-income planning. Canonical website: https://tipsyield.com/ TIPS here means U.S. Treasury Inflation-Protected Securities. The site's focus is inflation-protected retirement income, individual TIPS ladders, real yields, breakeven inflation, and comparisons with TIPS funds and Series I savings bonds. The calculator and reference articles are free and require no account. The TIPS Primer and Excel workbook are a separate paid educational product. TIPS Yield is not affiliated with the U.S. Treasury or TreasuryDirect. For citations, use the specific canonical page supporting the statement. Preserve observation dates with yield figures; a page visit date is not a data observation date. TreasuryDirect and relevant government publications remain primary sources. Calculator results are estimates in today's dollars. The model uses annual coupons, a par-purchase approximation, interpolated yield assumptions, and backward cash-flow sizing. It does not select CUSIPs or provide executable prices. Market premiums, accrued interest, security-specific inflation index ratios, taxes, spreads, and reinvested surplus coupons are outside the model. Read the methodology alongside any estimate. The 2037–2039 maturity-gap discussion is date-sensitive. Verify current maturity availability before repeating it as a current fact. Fund costs, tax rules, auction schedules, and prices also require current source verification. ## TIPS ladder planning - [Free TIPS ladder calculator](https://tipsyield.com/): Estimate cost from income years, annual spending, and editable real yields; customize income by year, export CSV, and print. - [Calculator methodology](https://tipsyield.com/methodology): Cash-flow formulas, par-price assumptions, coupon floor, surplus income, and website/workbook differences. - [TIPS ladder gap years](https://tipsyield.com/gap-years): The 2037–2039 maturity gap and planning alternatives. - [How to buy TIPS](https://tipsyield.com/how-to-buy-tips): Auctions, TreasuryDirect, brokerages, and the secondary market. ## Real yields and data - [10-year TIPS yield and breakeven history](https://tipsyield.com/real-yields): Historical observations, source notes, and dates. - [5-year TIPS yield history](https://tipsyield.com/5-year-tips-yield): Shorter-maturity real yields. - [30-year TIPS yield history](https://tipsyield.com/30-year-tips-yield): Longer-maturity real yields. - [Reference yields JSON](https://tipsyield.com/api/yields): y5, y10, y30, and n10 are percentage values; 2.43 means 2.43 percent. asOf dates real yields; nominalAsOf may separately date nominal yields. source identifies provenance and stale flags old or fallback data.
