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?
