Now, two scenarios are possible.

Given the net price, and after computing the GST-inclusive pricing:

First calculate the GST amount (A)

A = (P x r) / 100

Goods and Services Tax rate – r

Base or Total net price – P

Total or gross price G is

G = P + A

You can determine the pre-tax price using the following formula as long as you have the GST-inclusive pricing:

First determine entire GST amount A using gross price G

A = G – [G x {100 / (100 + r)}]

As a result, the Base or Total net price is as follows :-

P = G – A
