Found something wrong? Make it visible.

A correction can concern a formula, wording, broken link, accessibility barrier, or another product issue. This page opens your email app; it does not pretend to submit a report to a hidden server.

Choose a category

  • Formula: arithmetic, units, rounding, cost inclusion, a golden example, or a result label appears incorrect.
  • Wording: a definition, assumption, exclusion, warning, or explanation is unclear or misleading.
  • Broken link: an internal route, citation, export, or next-step link does not work.
  • Accessibility: a keyboard, focus, screen-reader, contrast, zoom, mobile, or print experience creates a barrier.
  • Other: a product-specific issue not covered above.

What to include

Include the category, page address, formula version if one is shown, what you expected, and what happened. An attachment is not required. Please do not include wages, revenue, quote descriptions, customer information, exported scenarios, or other private financial inputs.

How material formula corrections are handled

A material correction is reviewed against the formula specification and human-reviewed fixtures. If accepted, the change receives a new formula version, effective date, affected-tool list, saved-scenario impact note, and updated tests. The outcome is published in the formula changelog rather than silently replacing the earlier baseline.
