How to calculate GST in Singapore
Adding GST to a net price
GST = net × 9 / 100
gross = net × 1.09
Removing GST from a gross price
net = gross / 1.09
GST = gross − net
Do not subtract 9% from the total to find the net price — divide by 1.09 instead. Subtracting the percentage removes too much, because GST is only 8.26% of the gross amount.
