What is a Reverse GST Calculator?
A Reverse GST Calculator is a digital tool that computes the original price of a product or service before GST was applied. Unlike a standard GST calculator (which adds tax to a base price), this tool works backward to extract the pre-tax amount from the total price.
Who Needs It?
Businesses reconciling invoices
Accountants verifying tax filings
Consumers checking fair pricing
E-commerce sellers managing product listings
How Does the Reverse GST Calculator Work?
Our calculator uses a simple mathematical formula to isolate the pre-GST amount:
Original Amount=Total Amount1+(GST Rate100)
Example Calculation
If a product costs ₹1,180 (including 18% GST):
GST Rate = 18%
Original Price = ₹1,180 / (1 + 0.18) = ₹1,000
GST Amount = ₹1,180 – ₹1,000 = ₹180
