1. What is Reverse GST Calculation?

Reverse GST calculation helps determine the pre-tax amount when you know the total amount including GST. This is particularly useful for businesses that need to separate the tax component from their total receipts.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Total Amount — The amount including GST (in INR)
• Tax Rate — The applicable GST rate (18% = 0.18)

Explanation: The formula works backward from the total amount to find the original amount before tax was added.

4. Using the Calculator

Tips: Enter the total amount including GST in INR and the applicable tax rate (default is 0.18 for 18% GST). The calculator will show both the pre-tax amount and the tax amount.
