Reverse GST Calculator

What Is Reverse GST Calculation?

When you purchase an item, the price you pay often includes the Goods and Services Tax (GST). However, there are times when you need to know the base price—the amount before GST was added. This is where reverse GST calculation comes into play. By inputting the total price (including GST) and the applicable tax rate, you can determine the original cost.

Key Components of Reverse GST Calculation

To effectively use the reverse GST calculator, one must grasp its fundamental components:

• Original Price: The initial price of the product or service, either inclusive or exclusive of GST.
• GST Rate: The applicable tax rate imposed on the product or service.
• GST Amount: The tax component already included in the price.
• Final Price: The total price paid by the consumer, including GST.

How to Use the Reverse GST Calculator

Our user-friendly reverse GST calculator simplifies the process. Follow these steps:

• Enter the amount including GST: Instead of entering the fair value, enter the total amount including GST in the first field.
• Choose the GST Rate: Below the total amount field, choose the GST rate from the dropdown menu (i.e. 0.25%, 3%, 5%, 12%, 18%, and 28%).
• Click "Calculate" Button: After entering the total price and GST rate, click on the calculate button to see reverse GST.
• View Results: The calculator will display both the GST amount from the total amount that you entered and the amount excluding GST.

Example Calculation

Let’s walk through an example:

Suppose you purchased a laptop for ₹45,000, and the GST rate is 18%.

• Input Total Price: ₹45,000
• Specify GST Rate: 18%
• Click “Calculate”

The calculator reveals that the original cost (before GST) was ₹38,135.59

How to Calculate Reverse GST Yourself: A Step-by-Step Guide

1. Identify the Total Amount: Start with the total amount that includes GST.
2. Determine the GST Rate: Know the GST rate applicable to the product or service.
3. Calculate the Divisor: Formulate the divisor, which is 1 plus the GST rate in decimal form.
4. Find the Base Amount: Divide the total amount by the divisor to calculate the base price before GST.
5. Compute the GST Amount: Subtract the base price from the total amount to find out the GST charged.

Example of Reverse GST Calculation

Let's say the total amount paid including GST is ₹1,000 and the GST rate is 18%.

• Total Amount: ₹1,000
• GST Rate: 18%
• Divisor: 1.18 (since 1 + 0.18)
• Base Amount: ₹847.46 (₹1,000 / 1.18)
• GST Amount: ₹152.54 (₹1,000 - ₹847.46)
