INDEPENDENCE & TRANSPARENCY

Help keep the numbers honest.

Report a formula issue, stale source, incorrect default, or accessibility problem.

What to include in a report

Name the tool, describe the issue, and include the result you expected. An example with fictional values is usually enough to reproduce a calculation problem. For a source issue, include the source URL and the publication period if available.

The Contact page currently shows a demo form; it cannot deliver correction reports yet. Do not include account numbers, addresses, or private documents.

How corrections are handled

The operator should reproduce the issue, verify the formula or source, add a regression check where useful, and release the correction with a plain-language explanation. A reported concern does not automatically establish that a result is wrong.
