Accuracy matters on a site about financial data. When we make a mistake, we correct it and say so.

How to report an error

Use our contact page. Include the page address, what you believe is wrong, and, if possible, a source that supports the correction.

How we handle reports

  1. We review every report against the original source, such as the Treasury’s published data or TreasuryDirect’s formulas.
  2. If we confirm an error, we correct it as quickly as we can.
  3. For substantive errors, such as a wrong formula, a wrong historical value or a misleading explanation, we add a dated correction note to the affected page describing what changed.
  4. Minor fixes such as typos or formatting are corrected without a note.

Data errors

Our rate data is imported automatically from the U.S. Department of the Treasury. If the Treasury revises a published value, our next refresh replaces the stored value with the revised one. If our software displays a value incorrectly, we fix the software, re-check the affected data and note the correction on our methodology page.

Calculator errors

If a calculator produces an incorrect result, we correct the formula, add a test for the case that failed, and note the correction on the calculator’s page with the date.
