Advantages of GST Calculator

Here's why utilising an online GST calculator can be advantageous:

Ease of use and time-saving: Online GST calculators offer simplicity and speed, delivering instant results without the need for manual computations, thus saving time.

Accuracy: These calculators minimize the chances of errors inherent in manual calculations, ensuring precise results.

Breakdown of tax components: Taxpayers can accurately determine individual amounts for CGST, SGST, and IGST, which can be challenging to calculate manually using the GST tax formula.

Estimation of gross price: Users can also estimate the gross price for their chosen items, providing a comprehensive understanding of their tax obligations.

Once taxpayers have grasped their tax liabilities and have all the necessary details regarding their GST-related transactions, it's essential to file GST return within the stipulated due dates. Failure to comply with these regulations may result in additional charges.

How does the GST calculator work?

The GST Calculator operates based on a straightforward formula:

GST Amount = (Selling Price x GST Rate) / 100.

Here, the Selling Price is determined by adding the Cost Price and Profit Amount. The calculator factors in the Selling Price, representing the total value of goods or services subject to GST, and the GST rate, which fluctuates based on the nature of the goods or services.

The Total Selling Price is then computed by adding the Selling Price, GST Amount, and, if applicable, Cess Amount.

How can a GST calculator help you?

A GST calculator can help you in many ways, such as:

  • Calculate the GST amount and the net price of goods and services based on the GST rate and the original price. This can save you time and hassle by doing the GST calculation for you quickly and accurately.
  • Understand the GST structure and rates better and plan your budget accordingly. You can choose from different GST rates and categories, such as CGST, SGST, IGST, and UTGST, and see how they affect the GST amount and the net price.

What is GST (Goods and Services Tax)?

Goods and Services Tax or GST is a dynamic taxation system that is implemented in India. It simplifies and unifies the indirect taxation across the country through a comprehensive tax structure that includes goods and services under a singular tax slab. GST is designed to replace all indirect taxes and aims to remove tax barriers that existed between states. It has helped in enhancing the ease of doing business and creating a level playing field for businesses across the country. With the implementation of GST, businesses can avail numerous benefits such as better compliance, a significant reduction in tax evasion, and streamlined tax procedures. It has also helped to increase transparency and boost economic growth. Therefore, if you are looking for an unsecured business loan, then knowledge of GST is critical for a successful loan application process.

What is GST inclusive amount?

The GST inclusive amount is the total cost of goods or services that includes the Goods and Services Tax (GST) in India. Understanding the GST inclusive amount allows you to plan their finances accurately by factoring in the additional cost of GST. By taking this approach, you can make informed financial decisions and avoid unnecessary financial burden.

What is the GST exclusive amount?

The GST exclusive amount refers to the cost of goods or services without the inclusion of the Goods and Services Tax (GST) in India. It is important for you to understand the GST exclusive amount when making purchases to accurately calculate the total expenditure.

What is GSTIN?

GSTIN stands for Goods and Services Tax Identification Number. It is a unique 15-digit alphanumeric code assigned to every person or entity that is registered under the Goods and Services Tax (GST) regime in India. The GSTIN is based on the PAN (Permanent Account Number) of the taxpayer and contains information such as the state code, registration number, entity code, checksum digit, and defaulting status.

The GSTIN is used for various GST-related procedures, such as filing returns, claiming input tax credits, and making payments. The GSTIN verification can be done online on the official GST portal. The GSTIN helps to ensure transparency and compliance in the GST system and prevent tax evasion.

Tax components under GST

There are 4 components of GST:

Central Goods and Services Tax (CGST): Under GST, intra-state transactions are subject to the Central Goods and Services Tax (CGST), an indirect tax.

State Goods and Services Tax (SGST): Intra-state transactions related to the supply of goods and services are subject to this tax. Each respective state government is responsible for collecting this.

Union Territory Goods and Services Tax (UTGST): This is an indirect tax levied on the intra-state supplies of goods and services.

Integrated Goods and Services Tax (IGST): This is a separate tax included under GST. Imports and exports as well as interstate sales of goods and services are subject to this tax. The central government administers and collects the IGST in accordance with the IGST Act. It then divides the accrued tax among the various states involved in the sales.

How do you calculate GST?

GST calculation formula

To calculate GST, taxpayers can use simple formulas.

  • To include GST in the base amount:

GST = (Original Cost * GST rate) / 100
Base amount with GST = Original Cost + GST

For example: Original cost is Rs. 1000 and GST rate is 10%
GST = (1000 * 10) / 100 = 100

Base amount with GST = 1000 + 100 = 1100

  • To exclude GST from the base amount:

Base amount without GST = Base amount with GST / (1+ GST rate /100)

For example: Base amount with GST is Rs. 1100 and GST rate is 10

Base amount without GST = 1100 / (1+10 / 100) = 1000

Note: GST Reform 2.0 has streamlined the tax framework by replacing the previous general slabs of 12% and 28% with a simplified two-rate system of 5% and 18%, along with a special higher rate of 40% for certain goods.

Frequently asked questions

What is the percentage of GST in India?

In India, GST rates depend on the classification of goods or services. The recent reforms have simplified the previous four-tier system into three main tax slabs: 5%, 18%, and 40%. While some goods and services are exempt from GST, specific items like gold attract special concessional rates.

How do you calculate 18% GST on the total?

To calculate 18% GST on a total amount, start by identifying the original price of the product or service. Then, use this formula: GST Amount = (Original Price × 18) ÷ 100. For instance, if a service costs Rs.1,000, the GST would be Rs.180, making the total Rs.1,180. The 18% rate is the standard GST rate applicable to many goods and most services.

How can a manufacturer / wholesaler use the GST calculator?

A GST calculator enables manufacturers and wholesalers to quickly calculate the final selling price of their products. By entering the production cost, target profit margin, and the applicable GST rate (5%, 18%, or 40%), the calculator generates the total price. It also provides a detailed breakdown of the GST amount into CGST and SGST for intra-state transactions or IGST for inter-state sales.

How to calculate GST on MRP?

To calculate the GST amount included in a product’s MRP, you can use a reverse calculation method. Start by identifying the applicable GST rate. Then apply this formula: GST Amount = MRP – (MRP × 100 / (100 + GST Rate)). For example, if a product’s MRP is Rs.118 and the GST rate is 18%, the GST component would be Rs.18 (118 – (118 × 100 / 118)), making the base price Rs.100. This method helps to extract the tax portion already embedded in the final price.

On which value is GST calculated?

GST is calculated based on the transaction value of goods or services, which is the actual price paid or payable for the supply. This amount includes all expenses borne by the supplier, such as packaging, delivery charges, commissions, and other incidental costs. However, any discounts offered before or at the time of supply are subtracted. The GST rate—ranging from 5% to 40% depending on the category of the product or service under the revised GST slabs—is then applied to this transaction value.

How to calculate GST in case of reverse charge?

Calculating GST under the reverse charge mechanism (RCM) follows the same method as the forward charge, but the key difference is who is responsible for paying the tax. Under RCM, the recipient of the goods or services, rather than the supplier, is liable to pay the GST to the government. For instance, if a company purchases services worth Rs.10,000 with an 18% GST applicable under RCM, the company must directly pay Rs.1,800 (split as 9% CGST and 9% SGST) to the government. This amount can then be claimed back as Input Tax Credit (ITC), subject to eligibility.
