What is a GST Calculator?

A GST (Goods and Services Tax) Calculator is a financial tool designed to help you calculate the GST amount on products and services in India. Whether you need to add GST to a net amount or extract the base amount from a GST-inclusive price, this calculator simplifies tax calculations for businesses, professionals, and consumers alike.

Our GST Calculator makes it easy to determine exact GST amounts with accurate CGST and SGST/UTGST breakdowns, helping you with pricing decisions, invoice preparation, and tax planning.

Key Features: Calculate GST amounts in both directions (add or remove), view CGST and SGST/UTGST breakdowns, and visualize tax components with our interactive chart—all with just a few clicks!

How to Use the GST Calculator

Our intuitive GST Calculator offers two calculation modes and takes just seconds to use:

  1. Select Calculation Mode: Choose between "Add GST" (to calculate GST on a base amount) or "Remove GST" (to extract the base amount from a GST-inclusive price).
  2. Enter Amount: Input the amount for calculation (base amount or GST-inclusive amount, depending on the selected mode).
  3. Select GST Rate: Choose the applicable GST rate (5%, 12%, 18%, or 28% are the standard rates in India).

The calculator instantly displays the net amount, total GST amount, and the final amount with GST. It also shows the CGST and SGST/UTGST breakdown (each being half of the total GST). The doughnut chart visualizes the proportion of base amount versus tax components for better understanding.

GST Calculator Formulas Explained

The GST Calculator uses these simple formulas for accurate calculations:

Add GST Formula: Total Amount = Net Amount + (Net Amount × GST Rate)

Remove GST Formula: Net Amount = Total Amount ÷ (1 + GST Rate)

Where:

  • Net Amount = Base price before GST
  • GST Rate = Applicable rate in decimal form (e.g., 18% = 0.18)
  • Total Amount = Final price including GST
  • CGST = Half of the total GST amount
  • SGST/UTGST = Half of the total GST amount

These formulas are the standard methods used for GST calculations in business and commerce throughout India.

GST Calculation Examples

Let's look at practical examples to understand how GST calculations work in both modes:

Example 1: Adding GST

Net Amount Rs. 1,000
GST Rate 18%
CGST (9%) Rs. 90
SGST/UTGST (9%) Rs. 90
Total GST Rs. 180
Final Amount Rs. 1,180

Example 2: Removing GST

Total Amount (Including GST) Rs. 1,180
GST Rate 18%
Net Amount (Excluding GST) Rs. 1,000
CGST (9%) Rs. 90
SGST/UTGST (9%) Rs. 90
Total GST Rs. 180

Frequently Asked Questions About GST Calculator

What are the current GST rates in India? +

India follows a four-tier GST structure with rates of 5%, 12%, 18%, and 28%. Essential goods are typically taxed at lower rates or exempted, while luxury items and certain services attract higher rates. Additionally, there are special rates like 0.25% for rough precious stones and 3% for gold. The GST Council periodically reviews and updates these rates, so it's advisable to check the latest applicable rate for specific goods or services.

What is the difference between CGST, SGST, and IGST? +

GST in India is collected in three forms: CGST (Central GST), SGST (State GST), and IGST (Integrated GST). For intra-state transactions (within the same state), the GST amount is equally divided into CGST and SGST, each going to central and state governments respectively. For inter-state transactions (between different states), the entire GST amount is collected as IGST. For example, on an 18% GST rate, intra-state transactions would have 9% CGST and 9% SGST, while inter-state would have 18% IGST.

How do I calculate GST on an inclusive amount? +

To calculate GST from a GST-inclusive amount, use the formula: Original Price = Total Price ÷ (1 + GST Rate). For example, if an item costs Rs. 1,180 including 18% GST, the original price would be Rs. 1,180 ÷ 1.18 = Rs. 1,000. The GST amount would be Rs. 1,180 - Rs. 1,000 = Rs. 180. Our calculator automatically performs this calculation in the "Remove GST" mode, providing both the net amount and the tax component.

Do all products and services have the same GST rate? +

No, different products and services are taxed at different GST rates based on their classification. Essential items like food grains are either exempt or taxed at lower rates (5%), while standard goods and services typically attract 12% or 18% GST. Luxury or sin goods like high-end vehicles, tobacco products, and aerated drinks are taxed at the highest rate of 28%, sometimes with additional cess. The GST Council determines the rate applicable to each category of goods and services.

Is GST calculation different for businesses and individuals? +

The GST calculation formula remains the same for both businesses and individuals. However, businesses registered under GST can claim input tax credit (ITC) for the GST paid on purchases, which effectively reduces their tax liability. Individuals, as end consumers, cannot claim such credits. Additionally, businesses need to comply with GST filing requirements and maintain proper documentation of tax collected and paid, while individuals simply pay the GST included in their purchases.
