Hey Product Hunt! 👋

I'm Vikas, the creator of GrabCalc.

I built GrabCalc because I got tired of bloated calculator websites that demand your email, bury simple numbers behind slow multi-step forms, or sell your loan balances to third-party advertisers. You shouldn't have to navigate a maze just to see what a $300,000 mortgage costs at 6.5%.

GrabCalc is built on three simple principles:

1. 100% Client-Side Math: Every calculation executes locally in your browser. Nothing you type is stored, logged, or sent over any network.

2. Instant Reactivity: Sliders and inputs update numbers in real-time as you type—no page reloads, no calculate buttons.

3. Zero Bloat: Pure native HTML, CSS, and vanilla JS. No tracking scripts, no paywalls, and no account requirements.

Today, GrabCalc has 82 specialized calculators spanning mortgages, HELOCs, debt payoff, Coast FIRE, self-employment tax, and everyday math.

I’d love to hear your feedback on the UX, and if there’s a specific financial or mathematical tool you’ve always wished existed without ads, let me know in the comments and I’ll build it!

Thanks for checking it out! 🚀
