Let's talk

Yes — completely free, no exceptions. No subscription, no premium tier, no account, no email required. Every calculator on Calcgator is free to use indefinitely. There are no advertisements either. We believe free tools should actually be free.

Use the contact form above and select "Bug Report". Please describe what you were trying to calculate, what result you expected, and what the calculator showed instead. Mention the calculator name and your device / browser if possible — this helps us fix it faster. We prioritise bug reports and typically address them within 12 hours.

You can either use the contact form above (select "Suggest Tool") or visit our dedicated Suggest a Tool page. We add new calculators every week based on community requests. Popular requests from our community include BMI calculator, calorie needs, loan EMI, SIP returns and currency converter — if yours is different, we'd love to hear it.

Calcgator does not require any account, email or personal information to use any calculator. Your calculations stay on your device — we do not store or transmit them. We use standard anonymous analytics (page views, session counts) to understand which tools are popular. No personal data is sold or shared. See our Privacy Policy for full details.

If you'd like to embed or partner with us, reach out via the contact form (select "Partnership"). We consider integration requests on a case-by-case basis. Please don't reproduce our calculator code or content without permission — but linking to any Calcgator tool is always welcome.

All Calcgator calculators are built on published scientific standards, industry formulas and official guidelines (e.g. EFSA water intake guidelines, BEE energy ratings, ASHRAE BTU standards). However, results are estimates — real-world conditions vary. For health, medical or financial decisions, always consult a qualified professional. If you spot an inaccurate result, please report it as a bug and we'll investigate immediately.
