FinCalc is run by a small team. There is no support queue and no chatbot — mail reaches a person. Pick the address that matches what you need and you will get a faster, better answer.
The most useful message you can send us. If a rate, threshold or result looks wrong, tell us which calculator, what you entered and what you expected. We check it against the official source, fix the data file and note the change.
[email protected]Feedback, a calculator you wish existed, press and partnership questions, or embedding one of our tools on your own site.
[email protected]Vulnerability reports and anything affecting the safety of the site or its readers. Please include steps to reproduce; see our security.txt for disclosure preferences.
[email protected]We read every message. Corrections are handled first and usually within a few days; other mail can take longer. We cannot answer questions about your personal tax or financial situation — see below.
FinCalc publishes calculators and methodology, not advice. We are not accountants, tax advisers or financial advisers, and we cannot tell you what to do in your own case. For that, speak to a qualified professional in your country.
