The introduction of the Goods and Service Tax or GST in the indirect tax circuit was a big step in the simplification of the taxation process. Not only did it standardise the tax rate all over the country, but it also replaced a bunch of different taxes that were levied at different stages and places. GST has brought transparency, increased tax compliance, and reduced tax evasion. It has simplified the tax structure for businesses and improved the ease of filing tax returns.

However, its implementation has also faced some challenges and required businesses to adapt to the new tax regime. For those not well-versed in the concept or calculation of taxes, it may still be a little difficult to calculate and ascertain the value of GST. Let's take a look at how you can calculate GST yourself and how you can use tools like online GST calculators to make things easier for you.

What is GST?

GST stands for Goods and Services Tax, which is a comprehensive indirect tax levied on the supply of goods and services in India. The central and state governments implemented it on July 1, 2017, replacing multiple indirect taxes. GST is a destination-based tax system where the tax is collected at each stage of the supply chain, from the manufacturer to the consumer.

The objective of GST is to create a unified tax structure, simplify the tax regime, eliminate the cascading effect of taxes, and promote ease of doing business. It has streamlined the taxation process by integrating various taxes such as central excise duty, service tax, VAT, and others into a single tax. GST categorises goods and services into different tax slabs: 5%, 12%, 18%, and 28%, with certain essential items attracting lower rates or being exempted.

Types of GST:

Both the central and state governments administer GST through the Central GST (CGST) and State or Union Territory GST (SGST, UTGST) respectively. Additionally, an Integrated GST (IGST) is levied on inter-state transactions. Let's take a look at these different types of GST:

1. Central Goods and Services Tax (CGST): This is a component of GST levied by the central government on the intra-state supply of goods and services. The central government retains the revenue collected through CGST.
2. State Goods and Services Tax (SGST): SGST is the counterpart of CGST and is levied by the state governments on the intra-state supply of goods and services. The respective state governments retain the revenue collected through SGST.
3. Integrated Goods and Services Tax (IGST): IGST is applicable to the inter-state supply of goods and services as well as imports. The central government collects it but it is subsequently apportioned between the centre and the states. IGST ensures seamless tax credit utilisation across states.
4. Union Territory Goods and Services Tax (UTGST): UTGST is similar to SGST but is applicable to the supply of goods and services within union territories without a legislature. The respective union territories retain the revenue collected through UTGST.

GST Calculator

Now let's understand what a GST calculator is. A GST calculator is a useful tool that helps you calculate the Goods and Services Tax (GST) applicable to a particular transaction or amount. It simplifies the process of determining the GST amount and provides accurate calculations based on the GST rate and the value of the transaction. Individuals as well as businesses can make use of the GST calculator for their convenience.

This tool can be beneficial for businesses to calculate tax liability, issue proper invoices, and maintain accurate records. It also helps individuals understand the GST component of their purchases and assists in budgeting and financial planning.

In India, GST calculators are available online as web-based tools or as mobile applications, making it convenient for users to calculate GST on the go. They provide a quick and efficient way to ensure accurate GST calculations, saving time and effort in manual calculations.

How to Calculate GST Using a GST Calculator:

Because the purpose of an online GST calculator is to make the taxing process easier, using a GST calculator is extremely simple. You will just need some values related to your transaction and the calculator will do the rest.

Here's a step-by-step guide to using a GST calculator:

Step 1: Search for a reputable GST calculator on the internet or download a trusted GST calculator application on your mobile phone or other device. Make sure it is from a reliable source.

Step 2: Enter the pre-GST value of the transaction or the total amount on which GST is applicable. This could be the purchase amount, invoice value, or any other relevant value.

Step 3: Choose the appropriate GST rate that applies to your transaction. GST rates can vary based on the type of goods or services involved. Common GST rates in India as of June 2023 are 5%, 12%, 18%, and 28%.

Step 4: Determine whether the transaction falls under CGST (Central Goods and Services Tax), SGST (State Goods and Services Tax), or IGST (Integrated Goods and Services Tax) based on the nature of the transaction and the location of the buyer and seller.

Step 5: Click on the "Calculate" button or equivalent to generate the GST amount. The online GST calculator will instantly provide you with the GST amount, including the tax payable and the net transaction value.

In these simple steps, you can calculate GST on the tip of your fingers. However, it is important to make sure that the values of the transaction or other details you enter are accurate and correct to the best of your knowledge. Any wrong information that you enter will lead to you getting a wrong answer.

GST Calculation Formula:

You can calculate GST in India using simple formulas. There are 2 ways of calculating GST which have different respective formulas to calculate GST. These are:

1. To calculate the amount of GST to add to the original value of a product, or
2. To calculate the amount of GST to remove or deduct from the total value of the product.

Examples of GST Calculation:

Here are some examples of how you can calculate GST on the MRP of a product:

GST Calculation Formula:

GST = (Original Cost * GST Rate) / 100

Example of calculating GST using the formula:

Say, for example, you finally buy yourself a brand-new pair of headphones that you have wanted to buy for a while. These headphones cost you Rs. 3,000. Headphones belong to the category of 'headphones and earphones, whether or not combined with a microphone' which attracts a GST rate of 18%. In this sense, the GST calculation would be:

GST amount = (3000 * 18) / 100

= Rs. 540

Therefore, the total amount you would need to pay would be Rs. 3,540.

Reverse GST Calculation Formula:

This is the formula you would use if you wanted to figure out the specific amount of GST or the original cost of the product. This means you would calculate GST from the total amount of the bill you receive. You will have to substitute the values in this formula:

Original Cost = (Total bill amount) / (1 + (GST Rate/100))

Example of calculating reverse GST using the formula:

Now, consider again that you have bought new headphones. This time, you bought them from a physical shop and the seller has given you a bill of the amount inclusive of the GST. Say, your bill is for Rs. 4,200. Headphones fall in the category of 18% GST. Here is how you can calculate the original cost of the headphones:

Original cost = 4,200 / [1 + (18 / 100)]

= Rs. 3,559

This means, that your GST amount would be Rs. 4,200 - Rs. 3,559 = Rs. 641.

Calculation of Tax under GST

When GST came into the picture, it successfully kicked other complicated taxes like Excise Duty and VAT (Value Added Tax) out of the picture. This meant that the GST had a few benefits over the old tax routine.

Benefits of GST:

• Tax Structure: GST introduced a unified tax structure; a single tax replaced multiple taxes levied at different stages of the supply chain, such as Excise Duty, Service Tax, VAT, and others. This simplified the tax system.
• The Cascading Effect: In the old indirect tax regime taxes were levied on top of taxes, resulting in a higher tax burden. With GST, the Input Tax Credit (ITC) mechanism allows for the adjustment of taxes paid on inputs, thereby reducing the previous 'tax cascading'.
• Input Tax Credit: The old regime limited the input tax credit to certain taxes and often had restrictions. With GST, businesses can claim input tax credits for taxes paid on all inputs (subject to some conditions)
• Technology-Driven: GST introduced a technology-driven platform called the GST Network (GSTN) to facilitate registration, return filing, and other compliance activities. The use of technology has made tax administration more streamlined and efficient compared to the manual processes of the old regime.

Here is an example of how taxes were calculated on goods before GST existed and how they are calculated now:

Impact of GST on Product Pricing

Implementation of the new Goods and Service Tax (GST) eliminated a bunch of earlier taxes like the VAT (Value Added Tax) and CST (Central Sales Tax). This ultimately meant that the price of the product would be different compared to what it was before.

Let's take a look at the difference in a bill calculated based on the old tax system as against it calculated with GST:

As you can see in the example, calculating the GST on a product brings its pricing down by a significant amount. The greater the amount of the bill, the more significant the difference will be.

Advantages of Using a GST Calculator

Here are some of the benefits you get out of using an online GST calculator:

1. Accuracy: A GST calculator ensures accurate calculations by eliminating manual errors. It performs complex calculations based on the specified GST rates, allowing you to get the correct tax amounts quickly and with precision.
2. Time-saving: Calculating GST manually can be time-consuming, especially when dealing with large volumes of transactions. An online GST calculator automates the calculation process, saving you significant time and allowing you to focus on other important tasks.
3. Ease of Use: GST calculators are very user-friendly, making it easy for individuals, businesses, and professionals to calculate GST amounts. They typically have simple interfaces where you can input the necessary details and get instant results.
4. Multiple Tax Rates: GST involves different tax rates depending on the goods or services provided. A GST calculator can handle multiple tax rates and help you calculate the applicable tax amount accurately for each item or transaction.
5. Flexibility: Some online GST calculators provide additional features such as reverse GST calculation, which helps businesses determine the pre-GST value from the final amount. This can be useful when working with inclusive pricing or when verifying the tax components of an invoice.

The implementation of the Goods and Services Tax (GST) has brought significant changes to the Indian taxation system. Through its unified and streamlined approach, GST has simplified the complexities of the previous tax regime, benefiting businesses, consumers, and the economy as a whole.

Moreover, GST calculators have revolutionised the way you can calculate and manage your tax obligations under the Goods and Services Tax system. With their accuracy, time-saving capabilities, and ease of use, GST calculators have become indispensable tools for businesses and professionals alike.
