Corrections Policy

Last updated: July 11, 2026.

ARSIDIAN LLC aims to correct substantive errors on MortgageCalculatorPlus.com clearly and promptly after they are confirmed. This policy covers calculator output, formulas, factual content, data labels, source attribution, and material omissions that could mislead a reasonable reader.

How to report an error

Send a report through the contact form on our website. A useful report includes:

  • the exact page URL;
  • the calculator inputs, if the issue involves a result;
  • the result or statement you believe is incorrect;
  • the expected result or correction and how you derived it; and
  • a link to an official source, when the issue concerns a rule, limit, rate, or public program.

Please do not include Social Security numbers, account numbers, complete loan applications, tax returns, or other sensitive personal information.

How we evaluate reports

We try to reproduce calculation issues using the submitted inputs and compare factual claims with the responsible primary source. We consider the issue's effect on numerical results, financial understanding, user decisions, and the number of affected pages. A disagreement with an estimate is not necessarily an error when the page accurately states a broad assumption, but unclear assumptions may still warrant clarification.

Reports may be prioritized when they involve:

  • a formula, unit, sign, term, rounding, or input-handling error;
  • a misleading description of APR, payment components, affordability, or tax treatment;
  • an obsolete official loan limit, eligibility rule, or program description;
  • an incorrect source, data period, or geographic label; or
  • content that could materially change how a user interprets a calculator result.

What happens after confirmation

For a confirmed material error, we correct the affected formula or content, test related pages where the same logic is used, and update the review date when appropriate. A material calculation change is entered in the formula changelog with the effective date and a plain-language description. If the correction changes the purpose or meaning of a tool, its labels and explanatory content are updated with it.

Minor spelling, punctuation, formatting, accessibility, and broken-link fixes may be corrected without a public note when they do not change the meaning or result. We do not silently rewrite the history of material formula changes once the public changelog begins.

External data revisions

An official source may revise a series, replace a file, change methodology, or update a program after we publish. When that happens, we may update the Website to the new official release and identify the new observation date or vintage. A later revision by the source does not mean the earlier value was transcribed incorrectly at the time, so the changelog may distinguish a routine data refresh from a Website error.

Scope and response

We review good-faith reports, but we cannot promise a specific response time or individual reply in every case. We may decline requests to change accurate content, remove a documented limitation, adopt a lender's proprietary calculation, or treat marketing material as an authoritative source. The decision to correct a page is based on evidence and the standards in our Editorial Policy, not on whether a person or company is an advertiser.
