What is GST Calculator India | GST Rate & Tax Calculator Online?
A GST Calculator is a financial tool designed to calculate the Goods and Services Tax (GST) amount on products and services, helping businesses and consumers determine the final price including tax or the original price excluding tax.
Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services in India. Implemented on July 1, 2017, GST has replaced multiple indirect taxes such as VAT, service tax, excise duty, and others, creating a unified tax system across the country.
GST Structure in India
GST in India follows a multi-tiered structure with different tax rates for various categories of goods and services:
- 0% GST: Essential goods and services exempt from GST
- 5% GST: Essential commodities like food items
- 12% GST: Standard goods and services
- 18% GST: Standard goods and services
- 28% GST: Luxury goods and services
GST Calculation Methods
Forward Calculation (Exclusive to Inclusive)
When you have the original price (without GST) and need to calculate the final price (with GST):
GST Amount = Original Price × GST Rate
Final Price = Original Price + GST Amount
Reverse Calculation (Inclusive to Exclusive)
When you have the final price (with GST) and need to calculate the original price (without GST):
Original Price = Final Price × (100 / (100 + GST Rate))
GST Amount = Final Price - Original Price
Importance of GST Calculator
- Helps businesses accurately calculate tax amounts to be charged to customers
- Assists in determining the input tax credit available for businesses
- Enables consumers to understand the tax component in their purchases

Our GST Calculator provides a simple and convenient way to perform these calculations, whether you're adding GST to a price (forward calculation) or extracting GST from an inclusive price (reverse calculation). This tool is valuable for businesses, professionals, and consumers dealing with GST-applicable transactions.
Examples
Let's explore practical examples of how GST calculations work in different scenarios:
Example 1: Adding GST to a Product Price
Scenario:
A retailer needs to calculate the final price of a laptop that costs ₹50,000 (exclusive of GST) with an applicable GST rate of 18%.
Input Values:
- Original Price (without GST): ₹50,000
- GST Rate: 18%
Calculation:
GST Amount = Original Price × GST Rate
GST Amount = ₹50,000 × 18%
GST Amount = ₹9,000
Final Price = Original Price + GST Amount
Final Price = ₹50,000 + ₹9,000
Final Price = ₹59,000
GST Breakdown:
CGST (9%) = ₹4,500
SGST (9%) = ₹4,500
Interpretation:
The customer would pay ₹59,000 for the laptop, which includes ₹9,000 as GST (₹4,500 as CGST and ₹4,500 as SGST).
Example 2: Extracting GST from an Inclusive Price
Scenario:
A consumer purchased a smartphone for ₹23,600 (inclusive of GST) and wants to know how much GST was charged if the applicable rate is 18%.
Input Values:
- Final Price (with GST): ₹23,600
- GST Rate: 18%
Calculation:
Original Price = Final Price ÷ (1 + GST Rate)
Original Price = ₹23,600 ÷ (1 + 0.18)
Original Price = ₹23,600 ÷ 1.18
Original Price = ₹20,000
GST Amount = Final Price - Original Price
GST Amount = ₹23,600 - ₹20,000
GST Amount = ₹3,600
GST Breakdown:
CGST (9%) = ₹1,800
SGST (9%) = ₹1,800
Interpretation:
The original price of the smartphone before GST was ₹20,000, and the total GST charged was ₹3,600.
Example 3: Inter-State Transaction with IGST
Scenario:
A business in Delhi purchases goods worth ₹1,00,000 from a supplier in Mumbai, with an applicable GST rate of 12%.
Input Values:
- Original Price (without GST): ₹1,00,000
- GST Rate: 12%
- Transaction Type: Inter-state (between different states)
Calculation:
IGST Amount = Original Price × GST Rate
IGST Amount = ₹1,00,000 × 12%
IGST Amount = ₹12,000
Final Price = Original Price + IGST Amount
Final Price = ₹1,00,000 + ₹12,000
Final Price = ₹1,12,000
Interpretation:
The Delhi business would pay ₹1,12,000, which includes ₹12,000 as IGST. Unlike intra-state transactions, inter-state transactions have the entire GST amount charged as IGST instead of being split between CGST and SGST.
Example 4: Restaurant Bill with 5% GST
Scenario:
A small restaurant with an annual turnover below ₹1.5 crore charges a 5% GST rate. A customer's food bill before tax is ₹1,500.
Input Values:
- Original Price (without GST): ₹1,500
- GST Rate: 5%
Calculation:
GST Amount = Original Price × GST Rate
GST Amount = ₹1,500 × 5%
GST Amount = ₹75
Final Price = Original Price + GST Amount
Final Price = ₹1,500 + ₹75
Final Price = ₹1,575
GST Breakdown:
CGST (2.5%) = ₹37.50
SGST (2.5%) = ₹37.50
Interpretation:
The customer would pay ₹1,575 for the meal, which includes ₹75 as GST (₹37.50 as CGST and ₹37.50 as SGST).
Example 5: Luxury Item with 28% GST
Scenario:
A customer purchases a high-end television that falls under the 28% GST slab. The MRP of the TV is ₹1,28,000 (inclusive of all taxes).
Input Values:
- Final Price (with GST): ₹1,28,000
- GST Rate: 28%
Calculation:
Original Price = Final Price ÷ (1 + GST Rate)
Original Price = ₹1,28,000 ÷ (1 + 0.28)
Original Price = ₹1,28,000 ÷ 1.28
Original Price = ₹1,00,000
GST Amount = Final Price - Original Price
GST Amount = ₹1,28,000 - ₹1,00,000
GST Amount = ₹28,000
GST Breakdown:
CGST (14%) = ₹14,000
SGST (14%) = ₹14,000
Interpretation:
The original price of the TV before GST was ₹1,00,000, and the customer paid ₹28,000 as GST, making the final price ₹1,28,000.

Frequently Asked Questions
What is GST?
GST (Goods and Services Tax) is a comprehensive indirect tax levied on the supply of goods and services in India. It has replaced multiple indirect taxes such as VAT, service tax, excise duty, and others, creating a unified tax system across the country. GST works on the principle of "one nation, one tax."
What are the different GST rates in India?
India follows a multi-tier GST structure with four main rates: 5%, 12%, 18%, and 28%. Some essential items are taxed at 0% or are exempt, while luxury and sin goods may attract an additional cess on top of the 28% rate. The GST Council periodically reviews and adjusts these rates.
How is GST calculated?
To calculate GST, multiply the net price (excluding GST) by the applicable GST rate percentage. To calculate the net price from a GST-inclusive amount, divide the gross price by (1 + GST rate as a decimal). Our calculator allows you to perform both calculations easily.
What is Input Tax Credit (ITC) in GST?
Input Tax Credit is a mechanism where businesses can claim credit for the GST paid on purchases used for business purposes. This credit can be used to offset the GST liability on sales, effectively ensuring that tax is paid only on the value added at each stage of the supply chain, avoiding cascading tax effects.
Who needs to register for GST?
Businesses with an annual turnover exceeding ₹40 lakh (₹20 lakh for special category states) must register for GST. Some businesses, like those involved in interstate supply or e-commerce, must register regardless of turnover. Voluntary registration is also possible for businesses below the threshold who wish to claim input tax credit or sell to GST-registered businesses.
