Using Excel to Reverse Calculate GST
Here's how to do it: Use the Formula: To reverse calculate GST, the formula is =Total Price / (1 + GST rate). For example, if the total price is ₹118 with an 18% GST, the person would type =118 / 1.18' in Excel to find the original price of ₹100.
To determine the Reverse GST value, you need to calculate the amount of Base Price or the amount exclusive of GST. This can be done by using the formula given below. Once you have the base price, you can further calculate the Reverse GST amount by subtracting it from the GST-inclusive amount.

Formula to Calculate Reverse GST with Example
Base Price is equal to 100 / (100 + Value of an applicable GST Rate) * GST Inclusive Amount. After obtaining the base price, you can deduct it from the GST-inclusive amount to determine the Reverse GST amount.
For example, if the GST-inclusive price is $110, dividing by 1.1 would give a GST-exclusive price of $100. Accurate subtraction of GST from a price ensures businesses report the correct GST amounts on their tax invoices and Business Activity Statements (BAS).
