Report a reproducible error

Accuracy matters to us. If you believe a calculator result, formula, or figure is wrong, the most useful report is one we can reproduce.

Please include the calculator name or URL, the exact inputs you entered, the result you received, and the result you expected with a short note on why. Confirmed errors are corrected once they are verified, and the affected page's update date is revised.

• The calculator name or page URL.
• The exact inputs you used.
• The result shown and the result you expected.
• The source or worked example your expected result is based on, if you have one.

What we accept

The following are all welcome, whether through the form or by email:

• Calculation or formula errors.
• Outdated data, rates, or sources.
• Wrong units, unclear assumptions, or missing edge cases.
• Accessibility problems.
• Requests for a new calculator, or ways an existing tool could be clearer.

What not to send

Please do not send confidential, sensitive, or personal information. Do not include passwords, financial account numbers, government identifiers, health information, or anything you would not want stored in a support inbox.

Share only what is needed to reproduce an issue. Providing your email address is optional and is used only to reply to you.

Feedback is not professional advice

CalcDomain cannot give personalised financial, tax, or legal advice, and we cannot recommend specific lenders or products. Our replies clarify how a calculator works or confirm a correction; they are not advice about your own situation.

For decisions about your circumstances, please consult a licensed professional.

Privacy

Feedback you submit is handled as described in our Privacy Policy. Any email address you choose to include is used only to respond to your message and is never sold or added to a marketing list.
