Calculate GST for goods and services in India. Supports GST exclusive and inclusive calculations with CGST, SGST, and IGST breakdown.
GST (Goods and Services Tax) is a comprehensive indirect tax levied on the supply of goods and services in India. Our free GST calculator helps you calculate GST for any amount, whether you need to add GST to a base amount (GST exclusive) or extract GST from a total amount (GST inclusive).
The calculator automatically breaks down GST into CGST (Central GST) and SGST (State GST) for intra-state transactions, or IGST (Integrated GST) for inter-state transactions. This helps businesses, freelancers, and individuals accurately calculate GST for invoicing, tax filing, and financial planning.

GST is calculated by multiplying the base amount by the GST rate. For example, if the base amount is ₹10,000 and GST rate is 18%, GST = ₹10,000 × 18% = ₹1,800. Total amount = ₹11,800. GST is split into CGST (9%) and SGST (9%) for intra-state transactions, or IGST (18%) for inter-state transactions.
GST rates in India are: 0% (exempt), 5%, 12%, 18% (standard rate), and 28% (luxury items). Most goods and services fall under 18% GST rate. Essential items like food grains are at 0% or 5%, while luxury items attract 28% GST.
CGST (Central GST) and SGST (State GST) apply to intra-state transactions (within same state). Each is half of the GST rate. IGST (Integrated GST) applies to inter-state transactions (between different states) and equals the full GST rate. For example, 18% GST = 9% CGST + 9% SGST (intra-state) or 18% IGST (inter-state).
To calculate base amount from GST inclusive price: Base Amount = (Total Amount × 100) / (100 + GST Rate). For example, if total is ₹11,800 with 18% GST: Base = (11,800 × 100) / 118 = ₹10,000. GST Amount = ₹11,800 - ₹10,000 = ₹1,800.
Yes, our GST calculator is completely free to use. No registration required, no hidden charges. You can calculate GST for any amount and any GST rate instantly. The calculator supports both GST exclusive and GST inclusive calculations.
Use CGST and SGST when the supplier and recipient are in the same state (intra-state transaction). Each is half of the GST rate. Use IGST when the supplier and recipient are in different states (inter-state transaction). IGST equals the full GST rate and is collected by the central government.
