GST & Sales Tax Calculation

Goods and Services Tax (GST) is a value-added tax levied on most goods and services sold for domestic consumption. Whether you are a business owner calculating invoices or a shopper checking the tax on a bill, this tool helps you instantly find the tax amount.

Inclusive vs. Exclusive

  • Exclusive: The tax is added on top of the price (e.g., $100 + 10% Tax = $110).
  • Inclusive: The tax is already inside the final price (e.g., If you pay $110 and tax is 10%, the item cost $100 and tax was $10).
