A GST (Goods and Services Tax) calculator is a tool used to determine the amount of Goods and Services Tax applicable to a particular transaction. GST is a consumption tax levied on the supply of goods and services in many countries around the world. The calculator helps individuals and businesses quickly calculate the GST component of a total amount, facilitating accurate financial planning and transactional calculations.

Here's a basic description of how a GST calculator typically works:

Input Total Amount: Users need to input the total amount of a transaction, including the cost of goods or services and any other applicable charges.

Select GST Rate: The calculator allows users to choose the appropriate GST rate applicable to the goods or services in question. GST rates can vary for different categories of goods and services and are set by the government.

Calculate GST: Once the total amount and GST rate are entered, the calculator computes the GST amount by applying the selected percentage to the total. The formula for calculating GST is often expressed as follows:

GST Amount
=
Total Amount
×
GST Rate
100
GST Amount=
100
Total Amount×GST Rate
​

Display Results: The calculator provides the user with the GST amount, which represents the tax that needs to be paid on the transaction.

For example, if the total amount is $100 and the GST rate is 10%, the GST amount would be $10, resulting in a total transaction amount of $110.
