About TIPS Yield
An independent reference for understanding Treasury Inflation-Protected Securities, estimating ladder costs and working through the practical details of inflation-protected income.
What we publish
TIPS Yield provides a free ladder calculator, worked examples, dated market reference tables and a paid primer with an Excel workbook. The calculator runs in your browser. Its estimates are educational and do not select securities or place orders.
Editorial standards and sources
Reference articles are published under the byline of Graham Ellery. They link to TreasuryDirect, the U.S. Treasury, IRS publications and fund sponsors where relevant. Hypothetical examples state their assumptions separately from observed market data. A source link supports the associated statement. It does not imply endorsement of TIPS Yield.
Rules and figures come from primary documents where they exist: Treasury auction announcements and results, IRS publications, Bureau of Labor Statistics CPI releases and Federal Reserve Economic Data (FRED) for historical yield series. Fund details come from each sponsor's own pages. Each article carries a Sources note listing the official and sponsor sources it cites. Articles are not reviewed by a licensed financial, tax or legal professional, and they are not advice for any reader's situation.
How the numbers are prepared
Auction and CPI reference pages are generated from saved government data. They show calculations such as changes between auctions and the effect of reference CPI on principal. Automated checks verify required data fields, calculation examples and internal links. These checks do not constitute independent professional review. The calculator methodology explains the model, its formulas and its limitations.
Current real yields come from the Treasury's daily par real yield curve, with FRED as a backup source. On weekdays a scheduled job pulls fresh Treasury data, rebuilds the affected pages and publishes them only after the automated checks pass.
Market tables identify observation or snapshot dates, with auction and maturity downloads available for inspection. Source documents govern if a snapshot or calculation disagrees with them.
What the dates mean
Published records when a page first appeared on this site, which can be later than the event it describes. Updated records a change to the page. Data updated records an automated data refresh; it is not a new editorial review. A separate Editorially reviewed date, where present, is recorded independently and is not advanced by a routine data refresh. Yield observations have their own dates. Older pages remain historical references, not current quotes.
