Contact
We read every message. The more specific you are, the faster we can help.
Report a calculation problem
Please include: the calculator name, every value you entered, the result you saw, and the result you expected. That is usually enough to reproduce and fix an issue the same day.
Suggest a calculator
If a tool you need is missing, tell us the exact question you are trying to answer. New calculators are added regularly and requests are prioritised by how often they are asked for.
Business enquiries
For advertising, sponsorship or content partnerships, mention your organisation and what you have in mind.
Write to raghuks7090062109kpl@gmail.com. This is the only contact route for the site, and it is read by the person who maintains it.
What we can help with
- A calculator producing a result you believe is wrong.
- A page that will not load, or a link that goes nowhere.
- Something on the site that is unclear or badly explained.
- A calculator you would like added.
- Advertising, sponsorship or content partnership enquiries.
What we cannot help with
We cannot advise on your personal finances, recommend a fund, broker, insurer or stock, or tell you what to do with your money. We are not registered to give financial advice and would be doing you a disservice by pretending otherwise. For that, speak to a qualified adviser registered in your country.
We also cannot provide live market, gold or crypto prices — this site holds no market data, and every price used in a calculation is one you type in yourself.
Response time
We aim to reply within 2–3 working days. Reports of calculation errors are prioritised over everything else.
