GST is the Goods and Services Tax levied by the government of India on the manufacturers, sellers, and consumers of consumer goods and services at the national level. It is based on the principle of Value Added Tax (VAT). As GST is levied on value addition at each stage, a consumer has to pay only the GST charged by the last dealer or supplier in the supply chain.

How to Calculate GST using a GST Calculator?

Taxpayers are now aware of the amount of tax charged at each point of supply for products and services thanks to the implementation of GST. When calculating GST, taxpayers must be aware of the GST rates applicable to different categories. Under the new tax structure, the rates applicable are 5%, 12%, 18% and 28%.

GST Calculation Formula

The below mentioned formula is for calculating GST by taxpayer

Formula for GST calculation:

  • Add GST:
  • GST Amount = (Original Cost x GST%)/100

    Net Price = Original Cost + GST Amount

  • Remove GST:
  • GST Amount = Original Cost - [Original Cost x {100/(100+GST%)}]

    Net Price = Original Cost - GST Amount

Example of GST Calculation

In case a product is sold for Rs.2,000 and the GST rate applicable to it is 12%, then net price of the product will be Rs.2,000 + 12% of Rs.2,000 = Rs.2,000 + Rs.240 = Rs.2,240.

Tax Calculation under GST

Under the GST regime, manufacturers and dealers can benefit from input tax credit. Below is an example to show the difference in the amount of tax payable under the old tax system and the GST system:

Value to Manufacturer Old Tax system GST System
Cost of production Rs.2,00,000 Rs.2,00,000
Profit Margin of 10% Rs.20,000 Rs.20,000
Excise duty of 12% Rs.24,000 -
Total production cost Rs.2,44,000 Rs.2,20,000
VAT of 12.5% Rs.30,500 -
SGST of 6% - Rs.13,200
CGST of 6% - Rs.13,200
Invoice value for manufacturer Rs.2,74,500 Rs.2,46,400
Value to Wholesaler
Cost of goods Rs.2,74,500 Rs.2,46,400
Profit margin of 10% Rs.27,450 Rs.24,640
Total Value Rs.3,01,950 Rs.2,71,040
VAT of 12.5% Rs.37,743.75 -
SGST of 6% - Rs.16,262.40
CGST of 6% - Rs.16,262.40
Invoice value to wholesaler Rs.3,39,693.75 Rs.3,03,564.80
Value to Retailer
Cost of goods Rs.3,39,693.75 Rs.3,03,564.80
Profit margin of 10% Rs.33,969.375 Rs.30,356.48
Total Value Rs.3,73,663.125 Rs.3,33,921.28

SGST of 6% - Rs.20,035.28
CGST of 6% - Rs.20,035.28
Invoice value to retailer Rs.4,20,371.125 Rs.3,73,991.84

Impact of GST on Product Pricing

Indirect tax will be levied by Central and State Government called Central GST (CGST) and State GST (SGST), respectively. In the case of intra-state transactions, the seller will collect CGST and SGST from the buyer which will be paid to the Central and State Government, respectively. Listed below is an example of the impact of GST on product pricing:

Old Tax System GST System
Price of a product sold from Pune to Jaipur = Rs.1,000 Price of a product sold from Pune to Jaipur = Rs.1,000
VAT @ 10% = Rs.100 CGST @ 5% = Rs.50 + SGST @ 5% = Rs.50
Cost of a product sold from Pune to Jaipur = Rs.1,100 Cost of a product sold from Pune to Jaipur = Rs.1,100
Profit = Rs.1,000 Profit = Rs.1,000
Selling Price = Rs.2,100 Selling Price = Rs.2,100
CST @ 10% = Rs.210 IGST @ 10% = Rs.110
Total cost of the product = Rs.2,310 Total cost of the product = Rs.2,210

GST Bill Rates and Its Calculation

The GST Bill is touted to be a landmark bill with respect to taxation in India. This Bill is being implemented with the intention of curbing ‘double-taxation’ and irregularities regarding the same. On 29 March, 2017 four bills were approved. The government has set a deadline of 1, July 2017 for the complete implementation of this Bill. A number of products and services would become cheaper and others would become heavier on the wallet. However, instead of the expected single tax slab, a multi-tier tax slab has been put forth with four different tax rates of 5%, 12%, 18% and 28%. The justification behind this multi-tier system is that essential goods and services cannot be taxed at the same rate as luxury products and services.

However, there are a number of confusions and doubts regarding the calculation of GST on products and the difference that would be made with the implementation of this landmark Bill. It is essential to note that the GST Bill has two components to it - one that is levied by the Centre which is known as CGST or Central GST and the other which is levied by all States known as SGST or State GST. Rates for each would be approved based on revenue and acceptability, among other factors. Except for those goods and services that have been exempted, SGST and CGST will be applicable on all goods and services. Both Centre and States would have jurisdiction for the determination of tax rates and for all taxpayers based on the threshold for products and services that have been prescribed.

From the example, it's clear that subsuming excise duty is favourable to the end consumer. There is a reduction in cost for manufacturers, wholesalers, and retailers due to the subsuming of VAT, Service Tax, and Excise duty. Due to the reduction in cost, there will be a reduction in input tax credit.

Tax Calculation for Inter-State Sales

Integrated GST (IGST) will be levied by the Central Government on inter-state supply of goods and services. In the case of inter-state transactions, IGST will be transferred to importing state. In the old tax system, CST was charged over and above VAT and the excise duty for movement of goods between 2 states. In the GST system, IGST is the only tax levied on goods moving across state borders. Below is an example to understand the IGST system:

Value to Manufacturer Old Tax System GST System
Cost of goods Rs.1,00,000 Rs.1,00,000
VAT of 12.5% Rs.12,500 -
IGST of 12% - Rs.12,000
CST of 2% Rs.2,250 -
Total value to retailer Rs.1,14,500 Rs.1,12,000

As per the above example, it is clear that under the GST system, manufacturers, wholesalers, and retailers will see reduction in cost whether it is inter-state or intra-state sales.

Benefits of GST Calculator

Here are some of the key benefits of using a GST calculator:

  • It enables users to determine the net or gross product price on GST rates.
  • It enables users to differentiate between SGST, CGST and IGST and calculate each tax accurately.
  • It saves time by providing instant results.
  • It lowers the risk of human error when calculating the cost of products and services.
  • It is simple to use and helps you calculate GST in a hassle-free manner.

General Benefits of implementing GST in India

Implementing a single indirect tax is beneficial in many ways such as:

  • It not only helps in setting an international standard but also ensures transparency throughout the tax structure right from the manufacturer to the consumer.
  • The primary objective of implementing GST is to prevent double taxation of commercial goods. GST is expected to ultimately increase competition among the manufacturers and sellers to provide high-quality goods which in turn will boost the GDP of the country.
  • The reduce in tax will bring down the production cost for companies. Thus, increase the competition among exporters.
  • Inflation is expected to decrease after the implementation of GST.
  • It is also said that there will be a decrease in tax liability. Reduction in price is expected as input tax credit is available against output tax. Following taxes will be set-off with the same or with the different tax input credits


  • As observed in the previous examples, there have been changes noted in the type of tax and amount imposed.
  • Excise is generally applicable on capital goods during production used by manufacturer. Under the new Bill, excise on capital goods will be subsumed as there will only be a single rate of tax for each type of product.
  • Due to the subsuming of Service Tax, VAT, Excise, there will be a fall in the cost of wholesalers, manufacturers and retailers. This will in turn reduce the total cost to the manufacturer due to a reduction in procurement cost.
  • There will also be a fall in input tax credit for the retailer/wholesaler under GST.

Therefore, as observed there will be a fall in prices for the manufacturer. However, changes in GST rates will depend on the products and services.

  • No GST on fortified toned milk, but treated tamarind kernel powder to attract 5% tax

    The Goods and Services Tax (GST) will not be applicable on fortified toned milk and supply of non-sealed drinking water. However, treated tamarind powder will attract a GST of 5%. The 3 product categories are part of the list which consists of 11 items. The Ministry of Finance has tried to clarify the doubts in regards to these 11 items on the topic of implementation of the Goods and Services Tax (GST). Other product categories in the list include sugar which is processed from cane and beet, wipes using spunlace non-woven fabric, plasma products, etc. In two different circulars earlier, the Ministry of Finance had issued clarifications pertaining to the application of the Goods and Services Tax (GST) on products which are related to fertilisers and oil refinery industries.

    A senior official from the Ministry of Finance said that they are hoping that all 3 circulars will help to bring down the number of litigations and at the same time also help promote the ‘Make in India’ scheme. Tax Partner at EY, Abhishek Jain said that the rate clarifications will be required to address the vagueness of the rates that are being by some of the major industries including the automotive industry, fertilisers industry, oil refineries, and so on. He further added that this would also help in bringing uniformity in the rates which are charged by different players.

  • IMF asks India to consider simpler GST rate structure

    The International Monetary Fund (IMF) has recently described the Goods and Services Tax (GST) as a “milestone reform” in India’s tax policy. However, it has pushed for a simplified tax structure and the main reason for that is that multiple rate structure and other features might give rise to high compliance and administrative costs. The International Monetary Fund (IMF) said in one of its annual country reports that a dual rate structure with low standard rate and an additional higher rate on selected items can prove to be progressive and help preserve the revenue neutrality.

    The newly implemented indirect tax regime levied on the supply of goods and services in India came into effect on 1 July 2017. The IMF is of the opinion that the Goods and Services Tax (GST) is a milestone reform in the tax policy of India. It has taken the significant step of unifying and harmonising a number of indirect taxes across all the states in the nation that were levied by the states as well as the central government. A dual rate structure with low standard rate and an additional higher rate will help preserve the revenue neutrality and at the same time streamlining exemptions will further help to improve and reduce the compliance and administration costs. The IMF also added that with the consumption basket of the rich taxed at higher rates than that of the poor, the Goods and Services Tax (GST) as presently designed has an effective tax rate rising with household consumption.

  • GST Council accepts ‘transaction value’ to tax hotel tariff

    The GST Council has conceded to the year-long demand of the hotel industry to determine the leviable tax rate on the basis of the ‘transaction value’. This ascertains that the end-users of the service will not be charged at a higher tax rate for their stay at a hotel. The hotel industry had been lobbying for this change ever since the Goods and Services Tax (GST) was rolled out last year in the month of July. The use of ‘declared tariff’ for determining the tax rate which is meant to be charged to the customers would mean that the customers would have to pay taxes at a higher rate. This situation would be true even if the room tariff fell under a lower slab. The rates at which tax is charged for hotels are 12%, 18%, and 28%.

    The change has been notified by the centre as well as the states. The ‘declared tariff’ has been replaced with ‘value of supply’ which is equivalent to the transaction value. However, experts are of the opinion that the change should not have been restricted to just the room tariffs and should have been implemented on the restaurants inside the hotels as well. There are 3 tax slabs faced by hotels. The first one is for rooms with daily tariffs of Rs.1,000 to Rs.2,500 at 12%. The second one is for the rooms with daily tariffs of Rs.2,500 to Rs.7,500 at 18% along with input tax credit. The third one if for the rooms with daily tariffs of more than Rs.7,700 at 28% along with input tax credit.

  • GST Council cuts rates: Electrical appliances to get cheaper

    In the latest GST Council meeting held on the 21st of July, the council has slashed the tax rates on several general use items. These items include washing machines, TV, refrigerators, etc. Conceding the year-long demand, the Council has also considered putting sanitary napkins under the exempted category. The newly implemented tax rates have been made effective from the 27th of July. Reportedly, the new rates have been estimated to cost the government exchequer an estimated amount of about Rs.7,000 crore.

    In the last GST Council meeting that was held in January 2018, the Council had revised the rates of 29 items. Earlier, the mammoth rationalisation decision was taken in the month of November 2017 when more than 200 items were brought under the lower tax brackets from 28%, 18%, and 12%. However, the biggest cut in tax rates came in white goods. As per the decisions taken in the 28th GST Council meeting held on 21 July 2018, rates of 17 white goods have been brought down from the highest tax slab of 28% to 18%. These items include TVs, refrigerators, washing machines, grinders, juicer mixers, hair dryers, vacuum cleaners, shavers, electric irons, and so on. Simpler return filing process method was approved for entities enrolled under the Goods and Service Tax (GST) regime. The rates applicable on paints, wall putty, and varnish have also been slashed to 18% from 28%. In addition to these, the Council also clarified that the GST charged for hotels will be calculated on the actual tariff rates and not on the printed rates. Even the GST applicable on leather items has been slashed from 28% to 18%. However, no decision has been taken on the sugar cess. It is to be decided in the next Council meeting.

  • Experts say, new tax appeal rules will bring down litigation

    After the announcement of the new tax appeal rules, tax experts came up with the opinion that the higher the threshold will be set by the finance ministry for filing appeals over tax disputes, the lower will be the load on the tribunals and courts. It will help to reduce the litigation and also free up officials who would be able to focus and work on high value cases. They also added that this move will help reduce the cost of tax dues recovery and improve the ease of doing business in the nation at the same time. After the launch of the new tax appeal rule, Arun Jaitley said in a tweet that this move will lead to the revenue department withdrawing 29,580 appeals before various platforms. He added that this move reduces litigation by 37%.

    The increase in the threshold for filing appeals in the case of the Supreme Court is the sharpest with an increase from Rs.25 lakh to Rs.1 crore. In the case of tribunals, the threshold has doubled from Rs.10 lakh to Rs.20 lakh. The same for high courts has increased from Rs.20 lakh to Rs.50 lakh.

  • GST Council to consider rate cut on items with low revenue impact

    A reduction in the tax rates of a number of items might be considered by the Goods and Services Tax (GST) Council in their upcoming meeting on 21 July 2018. The items that have been shortlisted are those with low revenue impact. This decision has been taken as a part of the tax rationalisation exercise of the Council. Some of the items that could be considered for the reduction of tax rates might possibly include handicrafts, sanitary napkins, and handloom goods.
