GST Calculator
The GST Calculator is a simple online tool that helps you calculate GST on a given amount instantly. You can use it to add GST to a price or remove GST from an amount that already includes GST. The calculator also shows the GST amount, CGST, SGST, IGST and final amount.
Instead of calculating GST manually, enter the amount, select the applicable GST rate and choose the calculation type. The GST Calculator then provides the result within seconds.
What Is a GST Calculator?
A GST Calculator is an online calculation tool used to determine the tax amount and final price after applying Goods and Services Tax. It can be useful for customers, businesses, freelancers, students and anyone who wants to check a GST-inclusive or GST-exclusive price.
GST rates depend on the goods or services and their applicable classification. The official CBIC GST rate database provides item-specific GST rate information. Always verify the applicable rate before using the result for an actual tax transaction.
How to Use the GST Calculator
- Enter the amount you want to calculate.
- Select whether you want to add or remove GST.
- Select the applicable GST rate.
- Choose CGST + SGST or IGST.
- Click Calculate GST.
- Check the base amount, GST amount and final amount.
How GST Is Calculated
When GST is added to a price, the GST amount can be calculated using the following formula:
GST Amount = Original Amount × GST Rate ÷ 100
The final price is:
Final Amount = Original Amount + GST Amount
How to Remove GST From an Amount
If the displayed price already includes GST, simply subtracting the GST percentage from the total is not the correct method. The GST-inclusive amount has to be divided by the appropriate factor.
For example, if an amount includes GST at rate R:
Base Amount = GST-Inclusive Amount ÷ (1 + R ÷ 100)
The GST component is then:
GST Amount = GST-Inclusive Amount − Base Amount
What Are CGST, SGST and IGST?
CGST
CGST stands for Central Goods and Services Tax. It is one component of GST applied to eligible intra-state supplies.
SGST
SGST stands for State Goods and Services Tax. It is the state component applicable to eligible intra-state supplies.
IGST
IGST stands for Integrated Goods and Services Tax. It applies to eligible inter-state supplies and certain other transactions covered under the GST framework.
CBIC explains that the Centre administers CGST and IGST, while respective states administer SGST. 0
GST Calculation Example
Suppose the original price of a product is ₹10,000 and the applicable GST rate is 18%.
- Original amount: ₹10,000
- GST rate: 18%
- GST amount: ₹1,800
- Final amount: ₹11,800
If the transaction is an eligible intra-state supply, the 18% GST can be represented as 9% CGST and 9% SGST. For an eligible inter-state supply, the corresponding tax can be represented as 18% IGST.
Common GST Rates
Different goods and services can have different GST rates. Commonly encountered rates include 5%, 12%, 18% and 28%, but the applicable rate depends on the specific goods or services and relevant classification.
For the latest applicable rate for a particular product or service, check the official CBIC GST rate information rather than assuming a rate based only on the product category. 1
Why Use a GST Calculator?
- Calculate GST quickly.
- Check GST-inclusive prices.
- Calculate GST-exclusive prices.
- Calculate CGST and SGST components.
- Calculate IGST for eligible inter-state transactions.
- Avoid manual calculations.
- Use the calculator on mobile or desktop.
GST Calculator for Businesses
Businesses can use a GST Calculator to quickly estimate the tax component of a sale or purchase. It can be useful while preparing quotations, checking invoice calculations and understanding the tax component of a price.
However, an online calculator should not replace proper accounting records, tax invoices or professional tax advice where required.
GST Calculator for Customers
Customers can use the GST Calculator to understand how much tax is included in a quoted price. This can make it easier to compare a base price with the final GST-inclusive amount.
GST Inclusive vs GST Exclusive Price
A GST-exclusive price is an amount before GST is added. A GST-inclusive price already contains the GST component.
This distinction is important because adding GST and removing GST use different calculations. The Toolxy GST Calculator supports both options.
Important Things to Remember About GST
- The applicable GST rate depends on the goods or services.
- Do not assume that every product has the same GST rate.
- CGST and SGST generally represent the two components of eligible intra-state supplies.
- IGST is used for eligible inter-state supplies.
- The calculator provides a mathematical estimate based on the entered rate.
- Verify the applicable tax treatment from official sources for actual transactions.
