Formula
GST is added to the base amount in exclusive mode and extracted from the total in inclusive mode.
GST formulas
Exclusive: GST = Amount x Rate
Inclusive: Base = Total / (1 + Rate)
In exclusive mode, the entered amount is treated as the taxable value before GST and tax is added on top.
In inclusive mode, the entered amount is treated as already containing GST, so the calculator separates the base amount and tax component.
