What is GST?
Goods and Services Tax (GST) is an indirect tax used in many countries. It is a value-added tax levied on most goods and services sold for domestic consumption. The GST is paid by consumers, but it is remitted to the government by the businesses selling the goods and services.
Economic Impact
GST streamlines the tax structure, reducing the cascading effect of taxes and making goods more competitive in the global market.
GST Calculation Formulas
Add GST: Total = Net + (Net × Rate/100) | Remove GST: Net = Total / (1 + Rate/100)Adding GST calculates the final price after tax. Removing GST (GST Inclusive) helps find the original price before the tax was added.
Common Scenarios
Standard 18% GST
For a net amount of $1,000 at 18% GST, the tax is $180, resulting in a total of $1,180.
GST Inclusive Price
If a product costs $1,180 inclusive of 18% GST, the original net price was $1,000.
