Understanding GST Calculation

GST can be calculated in two ways: removing GST from a final price (Tax Inclusive) or adding GST to a base price (Tax Exclusive). This tool helps businesses and consumers quickly determine the exact tax amount.

GST Components

  • CGST + SGST: Applied when the supply of goods/services is within the same state (Intra-state). Usually split 50-50.
  • IGST: Applied when the supply is between two different states (Inter-state).

GST FAQs

Common questions about Goods & Services Tax

Goods and Services Tax (GST) is an indirect tax used in India on the supply of goods and services. It is a comprehensive, multistage, destination-based tax usually passed on to the consumer.

GST has three components: CGST (Central Goods and Services Tax), SGST (State Goods and Services Tax), and IGST (Integrated Goods and Services Tax).

GST Amount = (Supply Value * GST Rate%) / 100. Total Value = Supply Value + GST Amount.

GST Amount = Total Value - [Total Value x {100 / (100 + GST%)}].

From 22 September 2025, GST was rationalised into two main slabs: 5% (merit rate) and 18% (standard rate), plus a special 40% rate on select luxury and sin goods. The earlier 12% and 28% slabs were largely merged into these. Many essential items are exempt, and special rates apply to items such as gold (3%). Always confirm the rate for your specific HSN/SAC code before invoicing.
