Let’s assume that a product is sold for Rs. 5,000 and GST applicable to that product is 5%.
GST Amount = Rs. (5000 x 5%) = Rs. 250
Net Price = Rs. (5,000 + 250) = Rs. 5,250

2. Remove GST
GST Amount = GST included amount / (1 + GST Rate)

Let’s assume that GST included amount of the product is Rs. 5250.
GST Amount = Rs. 5250 / (1 + 5%) = 5250 / 1.05 = Rs. 5,000
