Reporting a wrong result
Corrections are taken seriously because a wrong figure on a tax or health page can cost someone real money or worse. Three things let the problem be reproduced exactly:
- The calculator name, or the link from your address bar after you pressed Calculate. That link carries your inputs. If you opened this form from a calculator page, both are already attached.
- The result you got and the result you expected.
- Where your expected figure comes from, if you have a source such as an authority's own calculator or a published rate.
Requesting a calculator
Requests are genuinely useful. Searches that find nothing are counted too, and the most-asked-for tools get built first. Say what you are trying to work out, what numbers you would have on hand, and what decision the answer feeds into. That last part matters most. It decides what the calculator should output, not just what it should compute.
What we cannot do
We cannot give financial, tax, medical or legal advice, review your individual circumstances, or tell you what to do with a result. Those are jobs for a professional who can take responsibility for the answer.
