GST Calculator - Frequently Asked Questions
How to calculate GST in India?
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.
What are the GST rates in India?
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.
What is the difference between CGST, SGST, and IGST?
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).
How to calculate GST inclusive amount?
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.
Is GST calculator free to use?
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.
When to use CGST/SGST vs IGST?
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.
