What Is GST?

GST stands for Goods and Services Tax. It is an indirect tax applied to eligible supplies of goods and services in India. The applicable GST rate depends on the product or service and the relevant tax classification.

How to Use the GST Calculator

• Select the calculation type: GST Exclusive or GST Inclusive.
• Enter the original amount in rupees.
• Select the applicable GST rate.
• Choose the appropriate tax type, such as CGST + SGST or IGST, if available.
• Enter a custom rate if the calculator supports it and you know the applicable rate.
• Click Calculate GST to view the result.
• Click Reset to clear the entries and start again.

1. GST Exclusive – Add GST

Choose GST Exclusive when the amount entered does not include GST. The calculator adds GST to the original amount to estimate the final price.

Example: If the original price is ₹1,000 and the applicable GST rate is 18%, the GST amount is ₹180 and the final price is ₹1,180.

2. GST Inclusive – Remove GST

Choose GST Inclusive when the entered price already includes GST. The calculator estimates the original price before GST and the GST component included in the total.

Example: If the total price is ₹1,180, including GST at 18%, the original amount is ₹1,000 and the included GST is ₹180.

3. GST Rate

The calculator displays GST rate options such as 0%, 5%, 18%, 40%, and Custom Rate. The rate applicable to a transaction depends on the relevant goods or services and the current tax rules.

Do not assume that every product or service attracts the same GST rate. Verify the correct rate before using the result for billing or tax compliance.

4. CGST, SGST and IGST

GST may be divided into different components depending on the nature and location of a transaction.

• CGST: Central Goods and Services Tax.
• SGST: State Goods and Services Tax.
• IGST: Integrated Goods and Services Tax.

For an eligible intra-state transaction, GST is generally divided between CGST and SGST. For an eligible inter-state transaction, IGST generally applies. The correct treatment depends on the transaction and applicable GST rules.

GST Calculation Example

Suppose a product costs ₹2,000 before GST and the applicable GST rate is 5%.

This example assumes that 5% is the correct GST rate for the transaction.
