Frequently Asked Questions

Important GST concepts explained simply.

GST Exclusive means the price quoted does NOT include tax; GST is added on top of the base amount (e.g., ₹1,000 + 18% GST = ₹1,180 total).
GST Inclusive means the quoted price already includes tax; our calculator extracts the original pre-tax base amount and tax component (e.g., ₹1,180 total = ₹1,000 base + ₹180 GST).
For Intra-State transactions (buyer and seller in the same state), GST is split equally between Central GST (CGST) and State GST (SGST). For Inter-State transactions (buyer and seller in different states), Integrated GST (IGST) is levied in full by the Central Government.
Base Price = Total Invoice Amount / (1 + (GST Rate / 100))
GST Amount = Total Invoice Amount - Base Price.
