What is GST?

GST in general means a tax on the consumption of almost all the goods and services. GST is applicable for all the businesses that annually exceed a certain amount, declared by the Govt. 

There are two types of GSTs:

GST Inclusive

GST inclusive means total amount after including the GST in the original price. In easy terms, tax is not charged separately from the customer because it is already included in the price.

GST Exclusive

GST exclusive means tax is not included in the price. So it will be added separately.

How is GST Calculated?

GST is calculated with two easy mathematical formulas. As there are two types of GSTs, we need to use two different formulas to calculate them.

 

For GST Exclusive:

GST Amount = (Original Price × GST Rate) / 100

Final Price = Original Price + GST Amount

 

Let’s calculate these with with an example:

For exclusives let's say the product price is $1000 and GST rate is 18%. Then if we calculate it with the formula:

 

GST Amount = (1000 × 18) / 100 = $180

Final Price = $1000 + $180 = $1180

For GST Inclusive:

GST Amount = (Original Price × GST Rate) / (100 + GST Rate) 

Base Price = Original Price − GST Amount

 

Let's take those same numbers. 

GST Amount = (Amount × GST%) / (100 + GST%)

Base Price = Amount − GST Amount

 

GST Amount = (1000 × 18) / 118 = $152.54

Base Price = $1000 − $152.54 = $847.46
