GST Calculator

Calculate GST amount and total price quickly.

What is a GST Calculator?

A GST Calculator is an online tool that helps you calculate Goods and Services Tax (GST) on a product or service. It can calculate the GST amount and the final price after adding GST.

The calculator can also work in reverse when the price already includes GST. This allows you to find the original price and GST amount from a tax-inclusive amount.

How Does a GST Calculator Work?

A GST calculator uses the entered amount and GST percentage to calculate the applicable tax. For a GST-exclusive price, GST is added to the original amount.

GST Amount = Original Amount × GST Rate ÷ 100
Total Amount = Original Amount + GST Amount

How to Use the GST Calculator

  1. Select whether you want to add GST or remove GST from an amount.
  2. Enter the amount.
  3. Select the GST rate.
  4. Click the Calculate GST button.
  5. The calculator will show the GST amount, CGST, SGST and total amount.

GST Calculator Example

Suppose the price of a product is ₹10,000 and the applicable GST rate is 18%.

GST = ₹10,000 × 18 ÷ 100 = ₹1,800

Therefore, the GST amount is ₹1,800.

Total Price = ₹10,000 + ₹1,800 = ₹11,800

The final price including 18% GST is ₹11,800.

What is CGST and SGST?

When applicable, GST on an intra-state transaction is generally divided into Central Goods and Services Tax (CGST) and State Goods and Services Tax (SGST). For an 18% GST rate, the calculation is commonly divided into 9% CGST and 9% SGST.

18% GST = 9% CGST + 9% SGST

Common GST Rates

Common GST calculation rates include 5%, 12%, 18% and 28%. The applicable rate depends on the type of goods or services and the relevant GST rules.

GST Inclusive vs GST Exclusive Price

A GST-exclusive price is an amount before GST is added. A GST-inclusive price already contains GST. The BestCalculator GST Calculator supports both types of calculations.

Why Use an Online GST Calculator?

Calculating GST manually can take time and may lead to calculation errors. An online GST calculator provides quick results and makes it easier to understand the tax amount and total payable amount.
