GST Rates in India – Overview

The Goods and Services Tax (GST) was introduced in India on July 1, 2017, marking a significant shift in the country’s taxation system.

The GST Council, a governing body, is responsible for determining the GST rate slabs for various goods and services.

How GST Rates are Categorized?

The GST rates in India are structured to cover a wide range of goods and services. Each category has a specific percentage of tax associated with it:

0% GST Rate: Certain essential goods and services fall under this category, making them exempt from GST. This includes items like fresh produce, milk, and educational services.

5% GST Rate: Goods such as household necessities and some essential services attract a 5% GST rate. This moderate rate aims to ensure affordability for consumers.

12% GST Rate: Products falling under this category include goods like computers and processed food items. Services like restaurant services also fall under the 12% GST slab.

18% GST Rate: Most goods and services fall under the 18% GST slab, which includes items like smartphones, electronic appliances, and various services.

28% GST Rate: Luxury goods and services are placed in the highest GST slab of 28%. This includes items like automobiles, premium consumer durables, and certain high-end services.

How to Calculate GST Rate?

To calculate the Goods and Services Tax (GST) rate, you can follow these steps:

Identify the type of supply: Determine whether the supply is taxable or not, where the supply is made, and to whom the supply is made. These factors will help you determine the applicable GST rate.

Determine the applicable GST rate: The GST rate varies based on the type of goods or services being supplied and the location of the supply. In India, for example, the GST rates are categorized under different chapters and headings, each with its own CGST, SGST/UTGST and IGST rates.

Using GST Rate Calculator:

There are online tools available, such as Vakilsearch’s GST rate calculator.

Consider specific policies and regulations: In some cases, specific policies or regulations may impact the GST rate for certain goods or services. For example, the National Green H2 policy may influence the GST rate for green hydrogen.

Understand the local regulations: Different countries have their own GST or VAT systems with varying rates. For example, in Australia, the Federal Government levies GST at a rate of 10% and distributes the revenue to state governments.

By following these steps and considering the specific factors that apply to your situation, you can accurately calculate the GST rate for your sales or supplies.

GST Calculation With Example

Let’s consider an example to illustrate GST calculation:

Suppose the net price of a product is Rs. 1,000, and the applicable GST rate is 18%.

GST Amount =

1, 000 × 18 %  = 180

The GST amount in this scenario would be Rs. 180, and the total cost including GST would be Rs. 1,180.

How to Add GST?

Adding GST can be done as follows:

  • Net Price = Original Cost + GST Amount

How to Remove GST from the Base Amount?

The following calculation can be followed to remove GST from the base amount:

  • GST Amount = Original Cost – (Original Cost * (100 / (100 + GST% ) ) )

Are there GST Calculation Tools?

Yes, many such digital firms exist in the market that offers the taxpayer a reliable method of GST calculation, applied and understood step-by-step. Consumers can use such tools on a digital platform to calculate the GST applicable to the sale price of a consumer good.

What is GST Inclusive Amount?

GST inclusive amount calculates the sale value of the product, including GST. Therefore it is clear that the tax is not calculated separately.

What is GST Exclusive amount?

GST Exclusive amount refers to the product’s sale value only without the tax amount. Therefore, GST Exclusive amount must always be lesser than GST Inclusive amount.


Calculating your GST needs to be done per the state government’s regulatory norm and/or the central government. However, the calculation and value of the GST amount shall vary in accordance with the product under consideration and the price or the value associated with the same.

Experts connected with the field of tax calculation agree that the imposition of GST remains at the rate of 18%, which needs to be calculated per the total sale value of the product and then added to the total amount. However, the rates of GST vary as per changes announced by the Government from time to time.
