Understanding GST Exclusive vs. GST Inclusive Calculations
The Goods and Services Tax (GST) Calculator helps businesses, freelancers, shopkeepers, and shoppers in India quickly calculate pre-tax net amounts, total tax components, and final invoice totals across all standard GST slabs (3%, 5%, 12%, 18%, and 28%).
• Remove GST (Inclusive): Net Price = Gross Price / (1 + GST% / 100) | GST Amount = Gross Price − Net Price
CGST, SGST, and IGST Breakdown
For intra-state transactions (within the same state), GST is divided equally between Central GST (CGST) and State GST (SGST)—for example, an 18% GST invoice splits into 9% CGST and 9% SGST. For inter-state supplies across state borders, Integrated GST (IGST) is charged at the full rate.
