Understanding GST Calculations

The Goods and Services Tax (GST) is an indirect tax used in many countries. It is typically added to the price of most goods and services.

How to Calculate GST

Adding GST

GST Amount = (Original Cost × GST %) / 100

Total Price = Original Cost + GST Amount

Removing GST

GST Amount = Total Price - [Total Price / (1 + GST% / 100)]

Original Cost = Total Price - GST Amount
