About GST Calculator India 2026
Calculate GST for all Indian tax slabs instantly. Supports GST-exclusive (adding GST to base price) and GST-inclusive (extracting GST from MRP). Shows CGST+SGST split for intra-state and IGST for inter-state transactions.
GST replaced 17 different indirect taxes when it launched in July 2017, creating a single unified tax structure across India. The current slabs — 0%, 5%, 12%, 18%, and 28% — are decided by the GST Council based on whether goods are essential, standard, or luxury/sin items. Restaurants typically charge 5% GST without input tax credit, while most services fall under 18%. Understanding whether a quoted price is GST-inclusive or GST-exclusive matters for freelancers issuing invoices, shoppers comparing prices, and business owners filing returns. This calculator handles both directions instantly and shows the exact tax split between CGST and SGST for intra-state transactions.
