How the GST Calculator works
Splits a price into taxable value and GST. Inclusive mode backs tax out of a printed total; exclusive mode adds tax on. Intra-state uses CGST+SGST; inter-state uses IGST.
Formula / method. Exclusive: tax = amount × rate / 100. Inclusive: tax = amount × rate / (100 + rate); base = amount − tax. CGST = SGST = tax / 2 when intra-state.
When to use it. Use it on a quote or a shop bill to see the tax line. It does not file GSTR-1 or decide place of supply for you.
How to run a comparison
- Open GST Calculator from Home search, the Finance Studio hub, or this URL.
- Copy amounts, rates or dates from a document you already have — not a round marketing figure.
- Read the headline result and any breakdown (schedule, slabs, or intermediate rows).
- Change one input at a time so you can see what actually moves the answer.
- Cross-check with a related calculator below, then confirm statutory rates before you act.
Nothing you type is uploaded for server-side processing. Save or screenshot an output if you need it later; we do not keep a server-side history.
Notes and assumptions
One rate at a time. Cess (compensation cess, luxury) is not added unless you include it in the rate.
Results are estimates for education and planning only. They are not financial, tax, medical, or legal advice. Slabs, scheme rates and product terms change; verify against official notifications or a qualified professional before acting.
