About Us
A fast, accurate and private GST calculator for India
GST Calculator India is a free online tool that helps shopkeepers, accountants, freelancers and everyday buyers work out GST instantly — add it, remove it, or reverse a price — with a correct CGST, SGST, IGST and UTGST split.
Why we built this tool
GST touches almost every transaction in India, yet most people do not have a quick, reliable way to check the numbers. Calculators on paper take time, and generic online calculators are often built for other countries, miss the CGST + SGST split, or bombard you with ads and signup walls.
We built GST Calculator India to be the exact opposite: fast, simple, India-first and completely free. The whole tool runs in your browser, so there is nothing to download, nothing to install and no account to create.
What the calculator does
- Add GST to a base price (Exclusive mode).
- Remove GST from an MRP or inclusive price.
- Split tax into CGST + SGST, IGST, or CGST + UTGST depending on where the supply happens.
- Apply discounts and payment gateway fees in the same pass.
- Work with any rate — 0%, 5%, 12%, 18%, 28% or a custom rate.
Private by design
Every calculation happens locally in your browser. The amounts you type are never sent to a server. The only things stored on your device are small preferences — your language, colour theme and a short list of recent calculations — so the site feels familiar when you return. You can clear this data at any time from your browser settings.
Free forever
GST Calculator India is free to use without limits — no hidden pricing, no paid tiers, no “premium” features. If you find the tool useful, the best thanks is sharing it with someone who needs it.
A quick note on tax advice
This tool helps with arithmetic only. The GST rate that applies to a particular good or service depends on its classification under current Indian GST law, which changes from time to time. For binding advice, consult a qualified tax professional or the official GST portal.
