This India GST calculator handles both exclusive and inclusive values. For intra-state examples it also shows an equal CGST and SGST split.
What this GST calculator shows
Enter an amount and GST rate, then choose whether the amount is GST-exclusive or GST-inclusive. The result separates the base value and tax amount; for an intra-state example it also shows the equal CGST and SGST split.
Use it for: quick quotation checks, invoice maths, price comparisons and extracting GST from a tax-inclusive amount. It is a calculator, not a GST registration or filing service, so confirm the applicable tax rate and place-of-supply treatment for the actual transaction.
