What Is a GST Calculator?
A GST Calculator helps you calculate Goods and Services Tax in India by adding the applicable GST rate to the original price. It shows CGST, SGST, or IGST based on the type of transaction.
How GST Works in India
GST in India is divided into CGST and SGST for intra-state transactions, and IGST for inter-state transactions. The total GST rate remains the same but the tax distribution changes.
GST Calculation Formula
GST Amount = Base Amount × GST Rate ÷ 100
Total Price = Base Amount + GST Amount
When to Use CGST and SGST
CGST and SGST apply when the buyer and seller are located in the same state. Each tax usually represents half of the total GST rate.
When IGST Is Applied
IGST applies to inter-state transactions and imports. The full GST amount is paid as IGST to the central government.
