Gananayantra is a free collection of everyday calculators built for Indian users — finance, networking, mathematics and more. Every calculation runs entirely in your browser: nothing you type is sent to a server, and there's nothing to sign up for.
Indian tax slabs, GST rates and similar rules change over time. Where a calculator depends on rules that can change, we show the year or version the calculation is based on, and we keep older years available so past calculations stay reproducible.
Gananayantra is an independent tool and is not affiliated with the Government of India, the Income Tax Department, the GST Council, or any bank or financial institution. Results are estimates and should not be treated as financial, tax or legal advice.
