About DecideCalc

A free, no-login, India-first platform of 50+ working calculators for life's biggest money, career, health & time decisions.

What we believe

Most calculator sites stop at a number. We give you a decision. Every tool ends with a clear result, a comparison, or a green/yellow/red signal — so you actually know what to do next.

Why DecideCalc is different

• No login, ever. Your data never leaves your device. There is no account storage and no tracking pixels.
• India-calibrated. GST slabs, tax regimes, city tiers, ₹ lakhs & crores — built for the Indian context.
• Loads in <2s. Pure HTML, CSS & vanilla JavaScript. Works on any phone, even on slow data.
• Every tool works. No "coming soon" cards, no broken links. If it's listed, it's functional.
