Questions people often ask.
Does gst calculator (india) upload my data?
No. This tool processes your input inside your browser. Your text and files are not sent to an application server. The static host receives page and asset requests; see our privacy explanation.
Is this tool free for work and study?
Yes. No account, paid API, usage subscription or watermark fee is required. You remain responsible for your content rights and checking results. Hosting providers and their free tiers are separate from this open-source software.
What should I check before relying on the result?
Arithmetic and wording only, not tax, legal or banking advice. Check current rates and rules with the relevant authority or your bank. Review important outputs against the source, especially financial, legal, identity, medical and research calculations.
How do I write an amount in words on a cheque?
Copy the words exactly as shown, add “only” at the end if your bank expects it, and draw a line through any space left so nothing can be added.
Is the GST rate up to date?
You enter the rate yourself, so the calculator never goes out of date. Check the current rate for your goods or service with the tax authority, because rates change.
