GST Inclusive Calculator
Find the base price and tax amount from a GST inclusive total.
Enter the total amount (which already includes GST) to find out the base price and the tax component.
If you have a total price that already includes GST, use this tool to calculate the original base price and precisely how much GST tax is included.
How to Use
- Enter the total amount (inclusive of GST).
- Select the applicable GST rate.
- The calculator extracts the base price and the tax component.
Formula
Base = Inclusive Amount / (1 + Rate/100)
Examples
Inclusive GST
If you paid ₹118 and the GST rate is 18%, the base price was ₹100 and the tax was ₹18. The tax is already 'included' in the ₹118.
