How this is calculated
Add: GST = Amount × Rate ÷ 100, Final = Amount + GST
Remove: Base = Amount ÷ (1 + Rate ÷ 100)GST calculations either add tax on top of a base amount, or work backwards to find the base amount when a price already includes GST. The GST rate itself depends on the category of goods or service.
