GST Calculator India for Businesses
Calculate GST-inclusive and GST-exclusive prices, GST amount, and an illustrative CGST/SGST split for an intra-state transaction. The tool is designed for quick pricing and invoice checks.
GST calculation
For an exclusive amount, GST is added to the base value. For an inclusive amount, the GST component is extracted from the total. The CGST/SGST split shown here assumes an eligible intra-state transaction with an equal split.
Important: GST treatment can differ for inter-state supplies, reverse charge, exemptions, special schemes and other circumstances. Use the correct rate and tax treatment for your transaction.
