By | November 6, 2021

The Goods and Services Tax, abbreviated as GST, is a type of tax imposed by the Indian government at the national level. On the internet, there are several GST Calculators that may be used to figure out how much GST would cost.

The GST is a nationwide tax imposed by the Indian government on dealers, makers, and consumers of goods and services.

GST evolved from the notion of Value Added Tax (VAT), which means it is applied at each stage of the supply chain and the consumer is responsible for paying the GST amount levied by the last dealer or supplier.

Some of the benefits of putting GST on products are listed below. 

The advantages of implementing a single indirect tax can be large and widespread. 

  1. This tax structure contributes to the maintenance of a worldwide standard. It also aids in ensuring that the maker and the consumer are on the same page.
  1. The elimination of double taxation on commercial goods is the main goal of the GST implementation. It encourages manufacturers and sellers to compete for high-quality items, which helps the country’s GDP grow.
  1. Manufacturers’ manufacturing costs are reduced as a result of the tax reduction, which boosts competition among exporters.
  1. The most important concern in the market, inflation, is expected to reduce with the installation of GST.

Taxpayers can learn about the various GST rates that apply to various categories under the new tax structure. These are 0 percent, 5%, 12%, 18%, and 28%, which are required when calculating GST.

GST has several tax heads:

GST is divided into four categories, each of which has its own set of rules.

  • State Goods and Services Tax (SGST): This tax is collected by the state government.
  • CGST (Central Goods and Services Tax): This tax is collected by the federal government.
  • UTGST (United Territory Goods and Services Tax): This tax is collected by the Union Territory Government 
  • Integrated Goods and Services Tax (IGST). The Central Government collects it for inter-state transactions and imports.

Interstate products are subject to IGST if the product’s supplier is in a different state and the product is delivered in a different state. Interstate supplies are taxed at an equal rate of CGST and SGST in this situation.

GST Calculation Formula: 

The taxpayer can use the formula listed below to calculate GST. The formula below can be used to compute the net price of a product after applying GST and then subtracting it.

The GST computation formula is as follows:

1. Include GST:

(Original Cost x GST Percentage)/100 = GST Amount

Original Cost + GST Amount = Net Price

2. Get rid of the GST:

Original Cost – [Original Cost x 100/(100+GST percent)] GST Amount = Original Cost – [Original Cost x 100/(100+GST percent)]

Original Cost – GST Amount Equals Net Price.

Calculation of GST using an example

Consider the following scenario: A product is sold for Rs. 2,000, and the GST rate is 12 percent.

The product’s net price is then Rs. 2,000 + 12 percent of Rs. 2,000.

This is Rs. 2,240 (Rs. 2,000 + Rs. 240).
