What is GST?

Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services. It replaces multiple cascading taxes with a single unified tax structure. GST is applied at every stage of the supply chain, with tax credits available for input taxes paid, ensuring that only the value added at each stage is taxed. Standard GST rates are 5%, 12%, 18%, and 28%.

CGST, SGST, and IGST explained

For intra-state transactions (within the same state), GST is split equally into Central GST (CGST) and State GST (SGST). For inter-state transactions (between different states), Integrated GST (IGST) is charged at the full rate. The total tax amount remains the same in both cases — only the split between central and state governments differs.

Inclusive vs exclusive GST

GST Exclusive means the price does not include GST — you add GST on top of the base price. GST Inclusive means the price already includes GST — you extract the GST component from the total. Our calculator handles both modes, making it easy to determine the exact tax breakdown for invoicing, pricing, or compliance purposes.
