Editorial policy
Everything here rests on Treasury's own rules and data, and nothing more.
Sources
Our rates, limits and cash-in rules are drawn from TreasuryDirect and the Fiscal Data service of the U.S. Treasury. We leave out rate forecasts, and we make no guesses about what rates will be.
Checking
Whenever Treasury sets a new rate, we refresh the table here and rerun the worked examples. We write in plain English, then read the copy against the source for accuracy before publication.
Independence
