About GST Calculator India

This advanced GST Calculator for India helps businesses, traders, freelancers, and consumers calculate Goods and Services Tax (GST) instantly. The calculator supports both CGST + SGST split for intra-state transactions and IGST for inter-state transactions.

GST in India is charged at different rates such as 5%, 12%, 18%, and 28%, depending on the goods or services. For intra-state sales, the GST amount is equally divided into CGST (Central GST) and SGST (State GST). For inter-state transactions, the entire tax is charged as IGST (Integrated GST).

GST Addition Formula

GST Amount = (Original Amount × GST Rate) ÷ 100
Total Amount = Original Amount + GST Amount

GST Removal Formula

Original Amount = Total Amount ÷ (1 + GST Rate ÷ 100)
GST Amount = Total Amount – Original Amount
