Calculate GST Instantly

This tool allows you to both add Goods and Services Tax (GST) to a net price and remove it from a gross price, making it essential for business owners and consumers.

What is GST?

Goods and Services Tax (GST) is a value-added tax levied on most goods and services sold for domestic consumption. The tax is included in the final price and paid by consumers, but it is remitted to the government by businesses. It's a common form of indirect tax used in many countries worldwide, sometimes known as VAT (Value-Added Tax).

How to Add GST to a Price

To find the gross price including GST, you input the initial amount and the applicable GST rate. The calculator finds the GST amount and adds it to the initial price.

• Example: An item costs $100 with a 10% GST rate.
• Calculation: $100 + (10% of $100) = $110. The GST amount is $10.

How to Remove GST from a Price

To find the pre-tax price from a total amount, you input the gross amount and the GST rate that was included. The calculator works backward to find the net amount.

• Example: A product costs $110, which includes a 10% GST.
• Calculation: The net price is $100, and the GST amount included was $10.
