Hey Product Hunt! 👋** I'm Shivam, the maker of HQCalc. It started with a simple frustration — every time I needed to calculate SIP returns, check my EMI, convert a PDF, or calculate BMI, I was opening 5 different websites. Half of them were slow, ad-filled, or asked me to sign up just to use a basic calculator. So I built HQCalc. What it is 130+ professional tools covering Finance, Investment, Health, Math, PDF and Converters — all in one place. No ads. No signup. No paywalls. Ever. **What makes it different:** → Works in 6 currencies (India, US, UK, UAE, Canada, Europe) → All calculations run in your browser — your data never touches our servers → Built with Next.js 15 for sub-second load times → Every financial formula verified against RBI, SEBI and Income Tax guidelines **Most used tools right now:** 💰 SIP & EMI Calculator 📊 Income Tax Calculator 2026-27 🧮 GST Calculator ❤️ BMI & Water Intake 📄 PDF Merger & Compressor I built this solo with the help of AI — and I'm just getting started. 120+ more tools are planned. Would love your honest feedback — what calculator do you use most that we should build next? **Try it free → https://hqcalc.com** Shivam Sagar Founder, HQCalc 🚀
