FAQ

GST calculator questions, answered.

Is this GST calculator accurate for Indian GST?

Yes, it follows the standard Indian GST calculation method with 5%, 12%, 18%, and 28% slabs, and splits the amount into CGST + SGST (intra-state) or IGST (inter-state).

What's the difference between adding and removing GST?

"Add GST" takes a GST-exclusive amount and adds tax on top. "Remove GST" takes a GST-inclusive amount (like an MRP) and works backward to show the base price and tax portion.

Is this a substitute for professional tax advice?

No. This tool is for quick estimates. Always confirm figures with your accountant or GST software before filing.

Is this free to use?
