Formula to Determine GST Amount
The GST amount calculator uses a standardized method to calculate GST. There are 2 aspects of this calculator: adding GST and removing GST from the total price of an item.
For adding GST, the following formula is used.
GST amount = (Price x GST%)
Net price = Cost of the product + GST amount
For example, if a product or service costs Rs. 100 and the GST levied on that is 18%, the GST amount will be 100 x 18% = Rs. 18. The net amount you’d have to pay would be Rs. 118.
For removing GST from the net price of a product, the following formula is used:
GST= Original cost – [Original cost x {100/(100+GST%)}]
Net price = Original cost – GST
For example, if the cost of a product after GST of 18% is Rs. 118, its original cost is 118 – [100/(100 + 18%)], which equates to Rs. 100.
For example, if the cost of a product after GST of 18% is Rs. 118, its original cost is 118 – [100/(100 + 18%)], which equates to Rs. 100.
