About GST
The government and many eminent economists have described the Goods and Services Tax as the biggest tax reform in the country. Goods and Services Tax is an indirect tax, and under it, a uniform tax is imposed on all goods and services. Before the GST bill was passed, 30 to 35% tax had to be paid on any item, and the tax imposed directly or indirectly on some goods was more than 50%, but after the arrival of GST, it became the same everywhere, i.e., about 28%. Now the question arises, what is the full name of GST? Friends, the full name of GST is Goods and Services Tax. GST is an indirect tax, in which the tax-paying persons get many facilities. Let us know further, with the implementation of the GST bill, market taxes like service tax, entertainment tax, etc., have all been included in GST.
How to Use a GST Calculator
Input the Product/Service Amount
Typically, entering the initial product or service cost or value is a good place to start.
It could be GST exclusive (amount before GST), or GST inclusive ( inclusive of GST).
Select GST Rate
Select the GST rate applicable to your region. For example:
In India, the GST rates are 5%, 12%, 18%, and 28%.
In Australia, the standard rate of GST is 10%.
For most calculators, there is a dropdown or input field where you can choose or enter the appropriate rate.
Now select the Calculation Type (Add or Remove GST)
Most calculators have two modes:
Add GST: When you have the base price, it calculates the total price inclusive of GST.
Remove GST: If you already have a GST-inclusive price, extract the GST component.
View the Results
The calculator will display:
GST Amount: The selected rate GST component.
Total Amount: If you choose to add GST, the total price includes GST.
Base Amount: The GST-free amount if you have decided to remove GST.
You can also calculate for different amounts or rates (Optional).
If you don't want to recalculate for a different amount, just change the value and see if the result changes.
GST Calculation examples
Goods and Services Tax (GST) is calculated using simple formulas based on whether the amount is GST-inclusive or GST-exclusive. Below are the key formulas and practical examples.
1. GST Calculation Formulas
A. Calculating GST on a GST-Exclusive Amount (Adding GST)
| GST Amount = Original Price × ( | | ) |
Total Price (GST-Inclusive)=Original Price+GST Amount
B. Calculating GST on a GST-Inclusive Amount (Removing GST)
| GST Amount = | | GST-Inclusive Price × GST Rate | | | 100 + GST Rate |
|
Original Price (GST-Exclusive) = GST-Inclusive Price - GST Amount
2. GST Calculation ExamplesExample 1: Adding GST (GST-Exclusive to GST-Inclusive)
Original Price (GST-Exclusive): ₹1,000
GST Rate: 18%
Calculations:
| GST Amount = 1000 × ( | | ) = ₹180 |
Total Price (GST-Inclusive) = 1000 + 180 = ₹1,180
Result:
GST Added: ₹180
Final Price: ₹1,180
Example 2: Removing GST (GST-Inclusive to GST-Exclusive)
Total Price (GST-Inclusive): ₹2,360
GST Rate: 18%
Calculations:
Original Price (GST-Exclusive) = 2360 - 360 = ₹2,000
Result:
GST Removed: ₹360
Base Price: ₹2,000
