How to Calculate GST?
GST can be calculated by multiplying the original amount by the GST rate and dividing by 100. The result is the GST amount. When GST is added, the total price becomes the original amount plus GST. When GST is removed, the base amount is calculated by dividing the total by one plus the GST rate.

GST Formula

Add GST:

GST Amount = Amount × GST Rate ÷ 100
Total Price = Amount + GST

Remove GST:

Base Amount = Amount ÷ (1 + GST Rate/100)
GST Amount = Total − Base Amount
