GST Calculator

The GST Calculator is a free online tool that can help individuals and businesses calculate the total GST, IGST, SGST/UTGST and CGST applicable on a transaction. It is also possible to calculate not just the final cost of the purchase, but also calculate the Goods and Services Tax (GST) paid based on the final value of the transaction. The results are instantly available to the user and error-free. To get better understanding of how the GST calculation works, let’s take a closer look at the GST calculation formula.

The formula to calculate GST on any good or service can be represented using the below formula:

• GST Payable = Price x Applicable GST Rate
• Total Amount Payable  = Cost of the product + GST amount

Here is an example based on the formula:

Let’s say you purchase a product priced at ₹10,000 with a GST rate of 18%, in this case

•  GST Payable = (10,000 × 18) / 100 = ₹1,800
•  Total Amount Payable =10,000 + 1,800 = ₹11,800

• Critical Illness rider, when added to your term plan, makes you eligible for tax deductions under Section 80D.
• Riders like Return of Premium, when chosen at the time of buying a term plan, increase its premium, thereby enabling you to save more money under Section 80C. You can check how the premium varies with the inclusion of riders using an online calculator.

•  Step 1. Choose whether you want to input the cost of the good or service inclusive of GST or exclusive of GST. In case you choose the inclusive of GST option, you will receive an output that shows the cost of good/service prior to GST and a breakdown of the IGST, CGST and SGST/UTGST applicable.
  
  On choosing the exclusive of GST option, the final amount payable will be displayed after factoring in applicable GST.
• Step 2. Enter the amount and choose the GST slab rate applicable to the transaction from the dropdown menu i.e. 5%, 18% or 28%.
• Step 3. Select whether the transaction qualifies as an interstate or intra-state supply. In the case of inter-state supply, applicable IGST will be displayed in the output, while not SGST or CGST will be applicable. Alternatively, in the case of intra-state supply, applicable SGST and CGST will be displayed, while no IGST will be applicable.
• Step 4. Once you have completed Steps 1 to 3, the GST calculator instantly displays the taxable amount, IGST, CGST, SGST and Total Amount payable including GST based on the inputs provided. These results are also displayed in tabular form.

Goods and Services Tax is calculated on the basis of pre-defined slab rates – 5%, 18%, 28%, etc. The exact GST rate applicable on a specific good or service is subject to periodic changes and review by the GST council. Additionally, some items such as fresh milk, fresh fruits, etc. are nil GST items i.e. no GST needs to paid when such items are bought or sold.

 GST payable is divided into three types:

• Central GST (CGST),
• State/Union Territory GST (SGST/UTGST), and
• Integrated GST (IGST)

 Among these different types of GST, CGST and SGST/UTGST are applicable if the buyer and seller are located within the same state or Union Territory i.e. in the case of an intrastate transaction. On the other hand, IGST is applicable on inter-state transactions i.e. when the buyer and seller are operating in different states/Union Territories.

The GST in India is applicable at different rates for different goods and services. The GST rate can be as low as 0% for a number of essential items and as high as 28% on goods/services considered as luxuries. Below are some of the key GST slab rates along with examples of goods/ services that incur the applicable GST Slab Rate.

Since the introduction of GST in India, insurance services have been within the ambit of Goods and Services tax. While the most common rate applicable in the case of GST on insurance services was 18%, the effective rate of GST was different depending the type of insurance plan chosen. This has now changed as of 22 September, 2025 as GST exempt status has now been granted to different types of individual life insurance and health insurance plans. Below table illustrates the GST rates applicable to different types of life insurance policies before and after 22^nd September 2025:

It is important to note here that the GST exempt status has been granted only to individual life and health insurance policies only. This means that GST will continue to be charged at the applicable rate in the case of group insurance plans even after the recent change.
