Reporting a calculation error
To help us check quickly, please include:
- The calculator page (its name or link).
- The exact values you entered.
- The result you got and the result you expected, with your source if you have one (for example a bank statement, official rule or textbook).
- Your device and browser if something did not display correctly.
We review every error report against the underlying rule or formula. Confirmed fixes are made promptly and the page’s “last updated” date is changed. See our editorial policy.
Suggesting a calculator
Tell us what you are trying to work out and who it would help. We prioritise ideas that many people need and that we can build from reliable, published formulas or official rules.
Please note
- We can’t give personalised financial, tax, legal or medical advice by email. For those, please consult a qualified professional.
- Please don’t send sensitive personal documents such as PAN, Aadhaar or bank statements. We don’t need them to look into a calculator issue.
- For advertising or partnership enquiries, use the same email address with “Partnership” in the subject line.
