What Is a GST Calculator?
A GST calculator is an online tool that helps calculate the Goods and Services Tax amount on a product or service. It can also calculate the final price after adding GST or the original price before GST.
Toolveta's GST calculator allows you to select common GST rates and calculate the GST amount, CGST, SGST and final amount quickly.
How to Use the GST Calculator
Enter the amount, select the applicable GST rate and choose whether the amount is GST exclusive or GST inclusive.
Click the Calculate GST button to see the GST amount and the resulting price.
GST Exclusive Calculation
When the amount does not include GST, the GST amount is added to the original price.
For example, if the price is ₹1,000 and the GST rate is 18%, the GST amount is ₹180 and the final price is ₹1,180.
GST Inclusive Calculation
When the entered amount already includes GST, the calculator can estimate the original price before GST and separate the GST amount.
For example, if the final price is ₹1,180 with an 18% GST rate, the GST component is ₹180 and the amount before GST is ₹1,000.
GST Formula
For a GST-exclusive amount, the basic formula is:
GST Amount = Original Amount × GST Rate ÷ 100
The final amount is:
Final Amount = Original Amount + GST Amount
CGST and SGST
For applicable intra-state transactions, GST may be divided into Central GST (CGST) and State GST (SGST).
For example, an 18% GST rate may be represented as 9% CGST and 9% SGST when the applicable tax structure requires an equal split.
The actual GST treatment depends on the nature and location of the transaction and applicable tax rules.
GST Calculation Example
Example: 18% GST on ₹1,000
GST = ₹1,000 × 18 ÷ 100 = ₹180.
Final amount = ₹1,000 + ₹180 = ₹1,180.
If divided equally, CGST would be ₹90 and SGST would be ₹90.
Common GST Rates
Common GST rate categories include 5%, 12%, 18% and 28%. The applicable GST rate depends on the specific goods or services and current tax rules.
Always verify the applicable rate using current official GST information when making an important tax or business decision.

Frequently Asked Questions
What is GST?
GST stands for Goods and Services Tax. It is an indirect tax applied to eligible goods and services according to applicable tax rules.
How do I calculate 18% GST?
Multiply the original amount by 18 and divide by 100. For example, 18% of ₹1,000 is ₹180.
What is the difference between GST inclusive and exclusive?
A GST-exclusive amount does not include GST, so GST is added to it. A GST-inclusive amount already contains GST, so the GST component needs to be separated from the total.
Can I calculate CGST and SGST?
Yes. For an applicable equal split, half of the GST amount is CGST and the other half is SGST.
Can I use this GST calculator on mobile?
Yes. The calculator works on mobile phones, tablets and desktop computers.
