About GST in India

Goods and Services Tax in India commonly applies at 0%, 5%, 12%, 18% or 28%. For intra-state sales the GST is split equally into CGST (central) and SGST (state); for inter-state sales the same total applies as IGST. This calculator adds GST to a base (exclusive) amount.

Frequently asked questions

How do I find the base from a GST-inclusive price?

Base = inclusive price ÷ (1 + rate/100). For example, ₹1,180 at 18% GST has a base of ₹1,000.
