Frequently Asked Questions
A Basic GST calculator helps you compute the GST amount on a given transaction. Simply enter the taxable amount, select the GST rate, and choose between exclusive (amount before GST) or inclusive (amount after GST) calculation.
Exclusive GST means the amount entered is before adding GST (e.g., ₹100 + 18% GST = ₹118). Inclusive GST means the amount entered already includes GST (e.g., ₹118 includes 18% GST, so base is ₹100).
For intra-state supplies (within the same state), GST is split equally between CGST (Central GST) and SGST (State GST). For inter-state supplies (between different states), full GST is charged as IGST (Integrated GST).
India has five GST slabs: 0% for essential items, 5% for essential goods/services, 12% for standard goods/services, 18% for most goods/services, and 28% for luxury items.
