📘 What is GST?

Goods and Services Tax (GST) is a value-added tax levied on most goods and services sold for domestic consumption. Introduced in many countries like India, Australia, Canada, and New Zealand, it replaces multiple cascading taxes with a unified structure.

GST can be:

• Inclusive (included in the total price)

• Exclusive (added on top of the base price)

📐 GST Calculation Formulas

👉 To Add GST (Exclusive Method):

GST Amount=Original Price×GST Rate100\text{GST Amount} = \frac{\text{Original Price} \times \text{GST Rate}}{100}GST Amount=100Original Price×GST Rate​ $$\text{Final Price}=\text{Original Price}+\text{GST Amount}$$

👉 To Remove GST (Inclusive Method):

Base Price=Final Price1+(GST Rate/100)\text{Base Price} = \frac{\text{Final Price}}{1 + (\text{GST Rate} / 100)}Base Price=1+(GST Rate/100)Final Price​ $$\text{GST Amount}=\text{Final Price}-\text{Base Price}$$
