How to calculate GST in India
Adding GST to a net price
GST = net × 18 / 100
Gross = net × 1.18
Removing GST from a gross price
Net = gross / 1.18
GST = gross − net
Remember that the tax share of a gross price is smaller than the rate itself: at 18% it is 15.25%. That is why you divide by 1.18 rather than subtracting 18%.
