GST Calculator online tool will calculate the amount of GST included in a gross price as well as the amount you should add to a net price.
GST tax calculation
GST amount = GST Rate(%) × Net amount
Gross amount = (100% + GST Rate(%)) × Net amount
Example
Net amount = 100000$
GST Rate = 6%
GST amount = 6%×100000$ = 6,000$
Gross amount = (100%+6%)×100% = 106,000$
