How to use the GST Calculator

  1. 1

    Enter the amount — either the price before GST or the final price including GST.

  2. 2

    Choose whether GST is to be added (exclusive) or is already included (inclusive).

  3. 3

    Pick the GST rate. Since 22 September 2025 most goods and services are at 5% or 18%, with 40% for luxury and sin goods.

  4. 4

    Choose intra-state (CGST + SGST) or inter-state (IGST) supply to see the split.

GST formula

Adding GST: GST = Price × Rate ÷ 100; Total = Price + GST

Removing GST: Taxable value = Total × 100 ÷ (100 + Rate); GST = Total − Taxable value

Intra-state: CGST = SGST = GST ÷ 2 Inter-state: IGST = GST

Inside one state the tax is split equally between the Centre (CGST) and the state (SGST, or UTGST in a union territory). Between states, or on imports, the whole amount is IGST.

Worked example

  • A laptop bag priced at ₹2,000 before GST at 18% attracts GST of ₹360, so the invoice total is ₹2,360.
  • Sold within Maharashtra, that ₹360 is ₹180 CGST + ₹180 SGST. Sold to a buyer in Karnataka, it is ₹360 IGST.
  • Going the other way, a GST-inclusive price of ₹1,050 at 5% has a taxable value of ₹1,000 and GST of ₹50.

GST rates in India after GST 2.0

The GST Council rationalised rates with effect from 22 September 2025. The 12% and 28% slabs were folded into two main rates, 5% and 18%, and a 40% rate applies to a short list of luxury and sin goods.

  • 0% — unprocessed food, fresh milk, education and health services and other exempt items.
  • 5% — daily essentials, many food items, agriculture inputs and medical equipment.
  • 18% — the standard rate for most goods and services, including electronics and professional services.
  • 40% — luxury and sin goods such as high-end cars and certain beverages.
  • 3% on gold, silver and jewellery and 0.25% on rough diamonds continue.

When to use inclusive and exclusive GST

Use exclusive when you know the base price and want the invoice value — for example when quoting to a customer. Use inclusive when you have a final price (an MRP or a bill total) and need to know how much of it is tax, which is how you work out the input tax credit on a purchase.
