Frequently Asked Questions
What is the difference between GST inclusive and exclusive?
GST Inclusive means the displayed price already includes the GST amount. GST Exclusive means GST is calculated on top of the base price. For example, ₹1,180 at 18% GST inclusive means the base price is ₹1,000 and GST is ₹180.
What are the current GST rates in India?
India has four main GST slabs: 5% (essential items), 12% (standard goods), 18% (most goods and services), and 28% (luxury items). Some items like alcohol and petroleum are outside GST.
How is CGST and SGST calculated?
For intra-state (within same state) transactions, the total GST is split equally into CGST (Central GST) and SGST (State GST). For example, at 18% GST, CGST = 9% and SGST = 9%. For inter-state transactions, IGST is charged at the full rate.
Can I use this for other countries VAT calculation?
While this calculator is designed for Indian GST rates, you can use the Percentage Calculator to calculate any percentage-based tax by entering the appropriate rate.
