Free GST Calculator


A GST (Goods and Services Tax) calculator is a tool that helps you calculate the amount of GST to be paid or added to the price of goods or services. GST is a consumption tax levied on the supply of most goods and services in many countries around the world. The specific rates and rules for GST can vary by country and even within regions of a country.

To calculate GST, you typically need to know the following information:

  • GST Rate: The applicable GST rate for the goods or services you are dealing with. This rate can vary depending on the type of product or service and the location.
  • Transaction Amount: The total amount of the transaction before GST is added.

Here's how you can calculate GST:

1. Calculate GST Amount:
   GST Amount = (Transaction Amount × GST Rate) / 100

2. Calculate Total Amount (including GST):
   Total Amount = Transaction Amount + GST Amount

For example, if you have a transaction amount of $100 and the GST rate is 10%, you can calculate the GST amount as follows:

GST Amount = ($100 × 10) / 100 = $10

Total Amount = $100 + $10 = $110

So, the total amount including GST is $110, and the GST amount is $10.

Keep in mind that this is a basic calculation, and GST rules and rates can vary widely depending on your location and the specific goods or services involved. Some countries have multiple GST rates for different types of goods and services, so it's important to use the correct rate for your calculation.

Additionally, businesses often use accounting software or POS systems that can automatically calculate GST for them, making the process more efficient and accurate.
