ACCOUNTABILITY

Corrections Policy

Material calculation errors are corrected transparently and assigned a new formula version when results can change.

How to report an issue

Send the calculator URL, inputs, observed result, expected result, jurisdiction, effective date, and supporting source to support@calculatebetter.com.

How corrections work

We reproduce the issue, verify authoritative sources, add a failing test, correct the formula, assign an appropriate version, update the review date, and document material changes.

Saved results

Saved scenarios retain their formula version. We do not silently rewrite historical scenarios when a calculation changes.
