What is GST?

GST, also known as Goods and Services Tax, refers to the goods and services supplied through indirect tax. GST first came to be on July 1, 2017, and through its existence, all indirect taxes in the country were replaced with GST.

The Central Government passed on the GST Act as the Budget Session in 2017. It was later approved by the Parliament on March 29, 2017. Many indirect taxes were eradicated, including VAT, Octroi, Central Excise Duty, and Entry Tax.

Goods and Services Tax was a comprehensive tax developed based on the sale, manufacture, and consumption of all goods and services available. To get registered under the GST policy, you need to have a GST Identification Number.

It doesn't matter if the company's IGST regimen is registered under the GST policy. If any sale transaction is made within the state (also known as Inter-state), a different kind of GST called Integrated GST is charged. Ventral and State GST is levied when dealing with any type of intra-state sales.

What is GST Inclusive amount?

A GST Inclusive amount is the total value of a product after you include the GST in the original cost. The tax is included and is not to be charged separately from a customer.

Different forms of GST

There are four kinds of GST that the government collects.

  • State GST (SGST) - This type of GST is collected by the State Government only.

  • Integrated GST (IGST) - This GST is only to be collected by the Central Government for any form of intra-state transactions, including imports.

  • Central GST (CGST) - The type of GST to be collected by the Central Government.

  • Union Territory GST (UTGST) - This type of GST is to be collected by the Union Territory Government.

How to Use GST Calculator?

As the name suggests, a GST calculator is a convenient tool for people who cannot manually find the GST. It is an online calculator that can find the payable GST for a month or maybe a quarter as well. Various types of people use the GST calculator, including manufacturers, buyers, and wholesalers.

Use the steps provided below to help you quickly access a GST calculator:

  • Enter the required details: You will have to enter essential details that include the net price of the goods or services and the GST rate as well. Be it 5%, 12%, 18%, and 28%; the rate is probably an essential piece of data needed.

  • After entering the details, you either need to click on the "Enter" or the "calculate" option depending on the website you are using. Then, the calculator will provide the tax amounts for every tax head; SGST, CGST, or IGST. Not only will the tax amount be displayed, but the gross price of the services and goods to be paid will be shown as well.

Example of GST:

Under the GST regimen, taxpayers are now allowed to know the amount of tax they need to pay for certain services and goods through a unified system of taxation.

To find out the exact amount of tax to be paid, the taxpayer should know the rate that applies to various options. There are different types of GST slabs; 12%, 28%, 18%, 5%.


GST amount = (original cost x GST percentage) / 100 Net amount = the original cost + the GST amount


Suppose some services or goods are being sold at $ 1,000 and the GST rate applied to it is 18%.

The net price would be calculated using the original amount and multiplying it with the GST percentage, then dividing it by 100. The total amount would then be determined

Numerical description:

(1,000 x 18) / 100 (This is to find the amount of tax in numbers rather than a percentage)

1,000+180 = $1,180 (The original amount added with the GST to get the final cost)

Instead of manually finding the GST of anything, you can also use the internet to help you. There are various kinds of easier methods that help you find the GST, including the use of a GST calculator.

Usage of GST Calculator:

  • It automatically gets rid of the effect of tax - Goods and Services Tax was designed as a comprehensive indirect tax to bring all kinds of indirect taxation under one roof. Through this, it will automatically get rid of the effect of tax that was evident earlier on.

  • An orderly scheme of composition for small firms - Small firms can benefit through GST because of the option it provides to them. It gives an option of lowering taxes through the usage of the Composition Scheme. Using this scheme, a huge burden was lifted off small businesses.

  • An easy and simple procedure conducted online - The entire process of GST, starting from the registration all the way to filing returns, is safely conducted online. This has made it very easy for start-ups who do not have the time or money to run around collecting different taxes one by one.

  • A defined platform for all kinds of E-commerce operators - Before the birth of the GST regime, the E-commerce sector wasn't thoroughly defined to supply goods. Online websites such as Amazon that were delivering products to places like Uttar Pradesh had to actually file a VAT declaration and mention the delivery truck's registration number. In some cases, the goods would be seized if the documents weren't produced.


The government is trying its best to make sure people acknowledge GST and go by it. However, it is easier said than done since many firms are yet to register for GST.

The GST Calculator uses percentage-based GST rates to find and determine the net or gross value of any goods or services. It can calculate all kinds of GST, including SGST, CGST, IGST, and many other ones as well. This calculator saves people a lot of their time. It also reduces human errors by using computing algorithms to calculate the GST within seconds.
