About the Reverse GST Calculator – Remove GST from Price
If a bill already includes GST, you may need the price before tax. Enter the GST-inclusive total and the GST rate, and this reverse GST calculator separates the pre-tax amount from the GST portion.
For example, a total of ₹11,800 that includes 18% GST is a pre-tax amount of ₹10,000 plus ₹1,800 of GST.
Reverse GST formula
Pre-GST price = total ÷ (1 + GST rate ÷ 100)
GST amount = total − pre-GST price
Do not subtract the rate percentage from the total: 18% of ₹11,800 is not the GST in it, because the percentage applies to the lower, pre-tax price.
Things to keep in mind
- Use the rate that applies to the item; rates differ and can change.
- The GST portion is always smaller than the rate times the total, since the rate is charged on the pre-tax amount.
- To go the other way and add GST to a price, use the GST calculator.

Frequently Asked Questions
- How do I calculate the price before GST from the total?
