Hey Product Hunt! š**
I'm Shivam, the maker of HQCalc.
It started with a simple frustration ā 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 ā all in one place. No ads. No signup. No paywalls. Ever.
**What makes it different:**
ā Works in 6 currencies (India, US, UK, UAE, Canada, Europe)
ā All calculations run in your browser ā your data never touches our servers
ā Built with Next.js 15 for sub-second load times
ā Every financial formula verified against RBI, SEBI and Income Tax guidelines
**Most used tools right now:**
š° SIP & EMI Calculator
š Income Tax Calculator 2026-27
š§® GST Calculator
ā¤ļø BMI & Water Intake
š PDF Merger & Compressor
I built this solo with the help of AI ā and I'm just getting started. 120+ more tools are planned.
Would love your honest feedback ā what calculator do you use most that we should build next?
