What is GST?

Goods and Services Tax (GST) is a unified indirect tax levied on the supply of goods and services in India. It replaced multiple indirect taxes (VAT, service tax, excise duty) with a single tax structure on July 1, 2017.

GST Exclusive: The base price does not include GST. Tax is calculated on top. Use this when pricing products before tax.

GST Inclusive: The total price already includes GST. The calculator extracts the base amount and tax component. Use this when you have an MRP or total invoice amount.

CGST + SGST vs IGST: For intra-state sales (within the same state), GST is split equally into CGST (Central) and SGST (State). For inter-state sales, IGST (Integrated GST) is charged at the full rate.
