How is GST calculated?

Since GST (Goods and Services Tax) was introduced, it has become easier for people to understand how tax is charged on goods and services at each stage of making and selling them.

To work out how much GST to pay, you need to know which GST rate (or 'slab') applies to the product or service.

Right now, the main GST rates are 5%, 12%, 18%, and 28% for most goods and services.

GST Calculation Formula

How to easily calculate GST

You can use this simple formula to work out GST:

GST Amount = (Original Cost × GST Rate) ÷ 100
Final Price (Net Price) = Original Cost + GST Amount

Example:

If a product costs Rs. 1,000 and the GST rate is 18%:

GST Amount = (1,000 × 18) ÷ 100 = Rs. 180
Net Price = 1,000 + 180 = Rs. 1,180

Types of GST Calculations

  • IGST (Integrated GST) – For sales between different states:
    IGST = Taxable Amount × GST Rate
  • CGST and SGST/UTGST – For sales within the same state or union territory:
    GST is split equally into:
    CGST = Taxable Amount × (GST Rate ÷ 2)
    SGST/UTGST = Taxable Amount × (GST Rate ÷ 2)

This method helps both businesses and customers easily calculate the GST and final cost of any product or service.

4 Types of Tax Under GST

The four main components of GST are as follows:

  • Central Goods and Services Tax (CGST): This applies to intra-state transactions and is collected by the central government.
  • State Goods and Services Tax (SGST): This applies to intra-state transactions related to goods and services and is collected by the state government.
  • Union Territory Goods and Services Tax (UTGST): This is applicable to intra-state transactions in union territories.
  • Integrated Goods and Services Tax (IGST): This applies to imports, exports, and interstate sales of goods and services. The central government collects IGST and distributes it to the relevant states.

Frequently asked questions

What is the percentage of GST in India?

The percentage of GST in India varies depending on the type of goods or service. There are four tax brackets, namely 5%, 12%, 18%, and 28%.

How do you calculate 18% GST on the total?

The percentage of GST in India varies depending on the type of goods or service. There are four tax brackets, namely 5%, 12%, 18%, and 28%. GST rates in India differ by product or service. Essentials like milk have 0% GST, while luxury items like cars and tobacco attract 28% plus a cess. Most goods fall under 5%, 12%, or 18% slabs. Most services are taxed at 18%. Some items are also GST-exempt, or NIL rated.

How can a manufacturer / wholesaler use the GST calculator?

Input the production cost or cost of goods, profit ratio percentage, and GST rate. The tool will then display the total production cost, along with CGST, SGST, and the overall tax amount.

How to calculate GST on MRP?

To calculate GST on MRP (Maximum Retail Price), first identify the GST rate for the product. Then, subtract the GST percentage from 100 to determine the base price percentage. For example, if the GST rate is 18%, subtract 18 from 100, leaving 82%. Divide the MRP by 118 and multiply the result by 100 to find the base price. The difference between the MRP and the base price gives you the GST amount. This method works for finding both the inclusive and exclusive GST amounts on MRP-based pricing.

On which value GST is calculated?

GST is calculated on the transaction value of goods or services, which is the price paid for the supply, including any additional costs like packaging, delivery, and commissions. Discounts given at the time of supply are deducted, while later discounts are not considered for GST calculation. The GST rate depends on the product category, and the applicable rate—ranging from 5% to 28%—is added to the transaction value. This comprehensive value serves as the base for calculating GST, ensuring that all additional charges are accounted for in the final tax calculation.

How to calculate GST in case of reverse charge?

Calculating a reverse charge is not very different from figuring out GST. A reverse charge is when the person who buys the goods has to pay the GST instead of the person who sells them. In both situations, the tax is the same. For example, if you bought items worth Rs. 10,000. At 18%, the GST to be paid will be Rs. 1,800. If CGST and SGST are charged, each will cost Rs. 900. The only difference is that in a reverse charge, the tax amount, which in this case is Rs. 1,800, is due by the recipient.
