About GST Calculator
Our free online GST calculator is designed to help businesses, accountants, and individuals quickly and accurately calculate Goods and Services Tax (GST) across multiple countries.
GST, or Goods and Services Tax, is a value-added tax levied on most goods and services sold for domestic consumption. Different countries implement GST with varying rates and structures:
India features a dual GST system with CGST (Central GST), SGST (State GST), and IGST (Integrated GST) with rates of 5%, 12%, 18%, and 28%. Australia implements a flat 10% GST on most goods and services. New Zealand applies a 15% GST rate across the board. Canada uses a combination of GST (5%) and HST (Harmonized Sales Tax) varying by province.
Unlike competitors that require multiple page navigations, our unified calculator provides instant results right on the homepage. For advanced features like CGST/SGST breakdown, calculation history, and visual charts, explore our full-featured calculator.
Frequently Asked Questions
A GST calculator is an online tool that helps you calculate the Goods and Services Tax on products or services. It supports adding tax to a net amount, extracting tax from a gross amount, and reverse calculations to find the original price before tax.
To add GST: Multiply the net amount by (1 + GST rate%). To remove GST: Divide the gross amount by (1 + GST rate%). For example, with a 10% GST rate, ₹100 becomes ₹110 when GST is added, and ₹110 becomes ₹100 when GST is removed.

Our calculator supports GST calculations for India, Australia, New Zealand, and Canada. Each country has different GST rates and structures, which are all accurately reflected in our tool.
Exclusive GST means the tax is added on top of the net amount (e.g., ₹100 + 10% GST = ₹110). Inclusive GST means the tax is already included in the total amount and needs to be extracted (e.g., ₹110 includes ₹10 GST, leaving ₹100 net).
