How to Calculate GST in India
GST (Goods and Services Tax) in India has four main slabs: 5%, 12%, 18%, and 28%. Our free GST calculator helps you instantly add or remove GST from any amount.
Adding GST (GST Exclusive)
If you know the base price and want to find the total with GST:
Total = Base Amount + (Base Amount × GST Rate / 100)
Removing GST (GST Inclusive)
If you have a price that includes GST and want to find the base amount:
Base Amount = Total Amount × 100 / (100 + GST Rate)
CGST, SGST, and IGST
For intra-state transactions (buyer and seller in same state), GST is split equally between CGST (Central GST) and SGST (State GST). For inter-state transactions, IGST (Integrated GST) is charged at the full rate.
