GST Calculator: Calculate GST Amount at the Current Rates
The GST Calculator helps you calculate the Goods and Services Tax applicable to a product or service. You can use it to add GST to a price, find the GST component already included in a price, or understand the total amount payable after GST.
Whether you are checking a quoted price, preparing an invoice or simply trying to understand GST, the calculator makes it easier to work out the taxable amount and GST separately.
How Is GST Calculated: Inclusive vs Exclusive?
GST Exclusive
When the price does not include GST, the tax is added to the original amount.
For example, if the taxable value is ₹10,000 and the applicable GST rate is 18%:
GST = ₹10,000 × 18% = ₹1,800
Total amount = ₹10,000 + ₹1,800 = ₹11,800
This is useful when you want to know how much GST should be added to a quoted or taxable price.
GST Inclusive
When the price already includes GST, the GST component needs to be separated from the total amount.
The formula is:
GST amount = Inclusive price × GST rate ÷ (100 + GST rate)
For example, if the final price is ₹11,800 including 18% GST:
GST = ₹11,800 × 18 ÷ 118 = ₹1,800
The taxable value is therefore ₹10,000.
The GST Calculator can perform both calculations, making it useful as a GST inclusive exclusive calculator.
What Are the Current GST Rate Slabs in India?
GST rates depend on the classification of the goods or services. The commonly used rate structure includes Nil, 5%, 12%, 18% and 28%, while certain specific goods and services can have different rates or exemptions. Precious metals and certain other categories can also have separate rates.
| GST Rate | General Application |
|---|---|
| Nil | Certain exempt goods and services |
| 5% | Specified goods and services |
| 12% | Specified goods and services |
| 18% | Standard rate applicable to many goods and services |
| 28% | Certain specified goods and services |
The applicable GST rate should always be determined from the classification of the particular product or service rather than assumed from the table alone. CBIC publishes product and service specific GST rate information.
GST is one part of the broader tax system. If you also want to estimate your personal tax liability, you can use the income tax calculator to calculate your estimated income tax.

What Is the Difference Between CGST, SGST and IGST?
The type of GST charged depends on whether the supply is within a state or between different states.
CGST is the Central Goods and Services Tax collected by the Central Government.
SGST is the State Goods and Services Tax collected by the respective state government.
For an intra state transaction, both CGST and SGST are generally charged. For example, if the applicable GST rate is 18%, it can generally be divided into 9% CGST and 9% SGST.
IGST is the Integrated Goods and Services Tax generally applicable to inter state supplies. Instead of charging CGST and SGST separately, the applicable IGST is charged on the transaction.
For example, on a taxable value of ₹10,000 at 18% GST:
| Type of Supply | CGST | SGST | IGST | Total GST |
|---|---|---|---|---|
| Within the same state | ₹900 | ₹900 | Not applicable | ₹1,800 |
| Between different states | Not applicable | Not applicable | ₹1,800 | ₹1,800 |
GST and TDS are different tax mechanisms. GST is charged on applicable goods and services, while TDS is deducted from certain specified payments. You can use the TDS calculator to calculate TDS on salary and other applicable payments.
The GST Calculator can therefore help you understand the total GST as well as the applicable tax components based on the transaction.
Frequently Asked Questions
1. How do I calculate GST inclusive and exclusive amounts?
For an exclusive amount, GST is calculated on the taxable value and added to it. For an inclusive amount, the GST component is separated from the final price using the applicable GST rate.
2. How do I add GST to a price?
Multiply the taxable amount by the applicable GST rate and add the resulting GST to the original price. For example, 18% GST on ₹10,000 is ₹1,800, making the total ₹11,800.
3. How do I remove GST from a total amount?
When the total amount already includes GST, divide the total amount by 100 plus the GST rate and multiply the result by 100 to find the taxable value. The difference between the total amount and taxable value is the GST component.
4. How can a buyer use the GST Calculator?
A buyer can use the calculator to check the GST component in a quoted price, compare inclusive and exclusive prices, and understand the total amount payable after GST.
5. Is GST the same for every product and service?
No. GST rates depend on the classification of the goods or services. Different products and services can attract different rates, including exemptions and specific rates.
