What are the GST slabs in India?

India has four primary GST slabs: 5% (essential goods and some food items), 12% (processed food, computers), 18% (most services, electronics), and 28% (luxury goods, automobiles). Some items are exempt (0%).

What is the difference between CGST, SGST, and IGST?

For intra-state transactions, GST is split equally between CGST (Central GST) and SGST (State GST). For inter-state transactions, IGST (Integrated GST) is collected by the central government and equals the full GST rate. For example, 18% GST on an intra-state sale = 9% CGST + 9% SGST.

Is GST applicable on all goods and services in India?

No. Certain items are exempt from GST, including fresh vegetables, milk, eggs, and some agricultural produce. Petroleum products, electricity, and alcohol for human consumption are outside the GST framework and taxed separately by state governments.

What is GST?

GST (Goods and Services Tax) is a comprehensive, multi-stage, destination-based indirect tax introduced in India on 1 July 2017. It replaced a complex web of over 17 central and state taxes — including VAT, Service Tax, Excise Duty, and CST — with a single, unified tax structure. GST is now applicable across the entire supply chain, from manufacturer to final consumer, with credit for taxes paid at each stage (Input Tax Credit).

GST Formulas — How the Calculator Works

Adding GST (Exclusive → Inclusive)

When your base price does not include GST and you need to compute the final price:


                    GST Amount = Base Price × (GST Rate / 100)

                    Total = Base Price + GST Amount

Example: ₹1,000 + 18% GST = ₹1,000 × 0.18 = ₹180 tax → Total ₹1,180

Removing GST (Inclusive → Exclusive)

When your price already includes GST and you need to find the pre-tax amount:


                    Base Price = Total / (1 + GST Rate / 100)

                    GST Amount = Total − Base Price

Example: ₹1,180 inclusive of 18% GST → Base = ₹1,180 / 1.18 = ₹1,000 → GST = ₹180

CGST, SGST, and IGST — What's the Difference?

For intra-state sales (seller and buyer in same state), the total GST is split equally between:

CGST (Central Goods & Services Tax) — goes to the central government
SGST (State Goods & Services Tax) — goes to the state government

For inter-state sales (seller and buyer in different states), the full GST is collected as IGST (Integrated GST) by the central government, which then distributes the state's share. Our calculator shows the CGST + SGST split in the results.
