About the GST Calculator
GST 2.0, effective 22 September 2025, cut most goods to two main slabs: 5% (merit) and 18% (standard), with a 40% rate for sin and luxury goods such as tobacco, pan masala and large cars. Gold and jewellery stay at 3% and rough diamonds at 0.25%. Within a state, GST is split equally into Central and State GST; between states it's charged as Integrated GST.
The formula
GST = value × rate; inclusive price ÷ (1 + rate) = value
