What is a GST Calculator?
A GST Calculator is an online tool that helps you calculate the GST amount and total price based on the GST percentage. Instead of calculating GST manually, you can enter the amount, select the required GST rate, and get the result instantly.
The calculator supports both common GST calculation requirements: adding GST to an amount and removing GST from a GST-inclusive amount.
How to Add GST Using This Calculator
When you select the Add GST option, the calculator calculates GST on your original amount and adds the GST amount to it.
Steps to add GST:
- Enter the original amount in the amount field.
- Enter the applicable GST percentage.
- Select Add GST.
- The calculator will instantly display the GST amount and the final amount including GST.
For example, if the original amount is ₹1,000 and the GST rate is 18%, the GST amount will be ₹180 and the final amount will be ₹1,180.
How to Remove GST from a GST-Inclusive Amount
The Remove GST option is useful when you already have a GST-inclusive price and want to find the original amount before GST was added.
Steps to remove GST:
- Select the Remove GST option.
- Enter the GST-inclusive amount.
- Enter the applicable GST percentage.
- The calculator will show the original amount before GST and the GST component.
This is especially useful for invoices, bills, product prices, accounting calculations, and business transactions where the final price already includes GST.
GST Calculation Formula
When GST needs to be added to an original amount, the GST amount can be calculated using:
GST Amount = Original Amount × GST Rate ÷ 100
The final amount including GST is:
Total Amount = Original Amount + GST Amount
For removing GST from a GST-inclusive amount:
Original Amount = GST Inclusive Amount × 100 ÷ (100 + GST Rate)
The GST component can then be calculated by subtracting the original amount from the GST-inclusive amount.
GST Calculation Example
Suppose the original amount is ₹5,000 and the GST rate is 18%.
GST Amount = ₹5,000 × 18 ÷ 100 = ₹900
Total Amount = ₹5,000 + ₹900 = ₹5,900
Therefore, the final price after adding 18% GST is ₹5,900.
