Corrections Policy

Reporting an error

Email contact@financecalculatorx.com with the calculator's address and — ideally — the shareable link produced by the Copy link button, which captures your exact inputs. Error reports are prioritized ahead of all other work; we aim to investigate within 7 days and usually much sooner.

How reports are verified

1. Reproduce. We run your exact inputs and confirm the reported output.
2. Check against references. The result is compared with the documented formula computed independently, our automated test suite, and — where applicable — authoritative references such as textbook examples or lender amortization statements.
3. Classify. Discrepancies split into three kinds: genuine calculation errors (a bug in formula or code), assumption mismatches (the calculator's documented convention differs from your lender's — e.g. daily vs monthly accrual), and expectation gaps (the math is right but the page explained it poorly).

What happens for each

• Calculation error: fixed immediately, a regression test is added so it cannot recur, the formula version increments, and the page's last-reviewed date updates. For material errors — anything that could meaningfully change a decision — a correction note is added to the affected page.
• Assumption mismatch: the page's assumptions section is clarified so the next reader isn't surprised.
• Unclear explanation: the copy is rewritten.

Scope

This policy covers calculator results, formulas, worked examples and factual statements in guides. It does not extend to differences of opinion about financial strategy, third-party sites we link to, or outcomes of decisions made using the tools — see the disclaimer for that boundary.
