Most Indian companies will sign up for GST. Thus, it's crucial to comprehend how it works and your duties as a business owner. When it comes to taxes, you need an accurate result. That's when a GST calculator comes into play. But you should also know how the rule works.

This guide will give you a complete guide to GST, including its definition and formulas. You can also find out how to calculate the rate. So let's join us to discover!

What Is A GST Calculator?

GST stands for Goods and Services Tax, an indirect tax charged on the supply of goods and services. It's a comprehensive tax that works on every stage and value of the products.

The government launched GST on 1st July 2017 and used it to replace most indirect taxes. There are five rates under GST: 0%, 5%, 12%, 18%, and 28%.

However, this tax doesn't apply to all products. Some exceptions include alcoholic drinks, petroleum, and electricity. Instead, the state governments tax them separately.

The GST calculator is a practical, ready-to-use web-based tool for calculating the GST. Buyers, producers, and wholesalers can take full advantage of this tool.

The streamlined GST calculator offers you a breakdown of percentage-based GST rates. It also assists you in calculating the cost of a net or gross product based on the quantity.

Besides, when working with GST, you will encounter some terms and calculations, such as:

  • CGST (Central Goods and Services Tax): This rate applies to any business within a state's boundaries or on a local scale.

  • SGST (State Goods and Services Tax ): Similar to CGST, this tax works on transactions inside states or an intrastate base.

  • IGST (Integrated Goods and Services Tax): Transactions between states or at the interstate scale are subject to this tax.

How to Calculate GST Percentage?

Thanks to the unified system, taxpayers know the tax imposed at multiple phases for various products and services under the GST regime. To calculate GST exclusive and GST inclusive, they must know the given GST rates we have mentioned.

For GST Addition

To calculate the GST exclusive, we have these formulas:

GST Amount = (Original Cost X GST Rate)/100

Net Price = Original Cost + GST Amount

For example, if the cost of your product is 100, and the GST rate is 18%, then your GST exclusive value will be:

GST Amount = Original Cost x GST Rate = (100 x 18)/100 = 18

Net Price = Original Cost + GST Amount = 100 + 18 = 118.

For GST Removal

To calculate the GST-inclusive value, we use these two formulas:

GST Amount = Original Cost - (Original Cost X 100100 + GST Rate)

Net Price = Original Cost - GST Amount

Let's say you purchased a product with a selling price of 105 (GST exclusive) that falls inside the 5% GST category.

Original cost = 105 - (105 X 100100 + 5)= 100

How Does GST Work?

To understand GST, you should start with your duties under regulations, which include the following:

Registering for GST

If your taxable turnover as a business reaches $1 million, you must apply for GST. Under the Reverse Charge and Overseas Vendor Registration systems, you will be liable for registration.

Charging GST

Once registered for GST, you must add GST to all taxable goods and services at the current GST rate.

The output tax you levy and receive is GST. Within a month of the end of an accounting period, output tax will be due to IRAS.

Claiming GST

If you have a GST registration, you can exclude the GST paid on your business's costs and expenditures as input tax on the GST return. It is dependent on you satisfying the needs for claiming the input tax.

If you meet specific criteria, you can also be eligible to claim GST that you paid before GST registration. At each step of a distribution chain, this input tax credit method assures that you only pay for the value-add.

Paying tax

The difference between input and output taxes is that you can pay the net GST or refund it to IRAS. In your GST return, you must include both in your report.

You have one month from the end of every specified accounting period to send your GST return. It often occurs every three months.

Examples For Understanding GST Calculation

Before a product gets to its final customer, it must go through multiple phases, and various taxes may be due on their way. This example will help you picture the whole process.

Phase 1: Manufacturing

Consider clothing manufacturing as an example, with a 10% GST. The firm purchases raw resources for INR 500, and its GST inclusive is 10% of INR 500. So we have a GST inclusive of INR 50.

During the production process, the manufacturer adds his value of INR 50 to the materials, raising his product's gross value to INR 550.

The total tax on the manufacturing of the garment is now INR 55. The manufacturer will be responsible for paying it under the present tax regime.

He can, though, subtract part of his tax under GST because he had paid it when he purchased the materials. As a result, the final GST for the manufacturer will only be INR 5.

Phase 2: Wholesale

The manufacturer sends the garment to the wholesaler. The gross value of the product is INR 550, with its GST inclusive being INR 55.

After adding his worth of INR 50, the wholesaler brings the total value to INR 600. It raises the total tax to INR 60, 10% of the total value.

The wholesaler can also set off the tax amount with the value he has previously added for buying the items from the manufacturer. Hence, the wholesaler's GST will be INR 5.

Phase 3: Retailer

The retailer purchases the clothes from the wholesaler for a gross value of INR 600, which includes INR 60 for GST.

The total cost of the items is INR 650 when he puts his value of INR 50. GST exclusive, in this case, is 65.

The retailer may set off the tax because he previously paid it when he bought it. As a result, the retailer's highest GST incidence will be INR 5.

Ultimately, because the retailer may sell the item for INR 650, the final consumer will only have to pay INR 65 (10% of 650).
