Response Times
We aim to respond to emails within a few business days. Because CalculatorHub is a small team, we prioritize reports that affect calculation accuracy over general feedback, but we read every message.
Before You Write In
If your question is about how a specific calculator works, check the "How It Works" and "Formula Used" sections on that calculator's page first — many common questions are already answered there. If you're still unsure, we're happy to help.
What to Include in Your Message
The fastest way to get a useful reply is to include a few specifics: the exact calculator page (or its URL), the inputs you entered, and what result you expected versus what you actually saw. A screenshot helps too, but isn't required. For general suggestions or feedback that isn't tied to a specific calculator, a short description of what you're looking for is plenty.
Business and Partnership Inquiries
For anything related to advertising, data licensing, content partnerships, or media inquiries, please use the same email address — [email protected] — with a brief description of your inquiry in the subject line so it reaches the right person promptly.
We Don't Offer Personalized Financial Advice
As a reminder, our team can help with technical issues, calculator accuracy, and general site feedback, but we can't provide personalized financial, tax, or legal advice for your specific situation. For that kind of guidance, we'd recommend speaking with a licensed professional — a financial advisor, accountant, or attorney depending on your question.
