This guide explores how GST works, how to calculate it, and how a digital GST calculator simplifies the process.
📘 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} Final Price=Original Price+GST Amount\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)} GST Amount=Final Price−Base Price\text{GST Amount} = \text{Final Price} – \text{Base Price}
