Corrections Policy

If you find a calculation error, send the URL and a reproducible example to support@finanacemath.com. The source of this address is the original website; inbox delivery has not been verified in this release.

Confirmed defects should receive a regression fixture and a dated correction note. Calculator totals and verification claims must reflect what has actually been tested. Legacy zero-rate defects were replaced with explicitly tested zero-rate paths.

Policy updated: 14 October 2026.
