Calculating Goods & Services Tax (GST)

Goods and Services Tax (GST), or Value Added Tax (VAT) in some regions, is an indirect tax applied to the supply of goods and services. Calculating GST is essential for businesses invoicing customers and for consumers understanding the final price of goods.

This calculator allows you to either:

• **Add GST:** Calculate the GST amount and the final gross price when you know the net price (before tax) and the GST rate.
• **Remove GST:** Calculate the original net price and the GST amount included when you know the gross price (including tax) and the GST rate.

How to Use

1. Select "Add GST" or "Remove GST".
2. Enter the known **Amount** (either Net Amount if adding, or Gross Amount if removing).
3. Enter the applicable **GST Rate (%)** for your location and the item/service.
4. Click "Calculate".

The results will show the Net Amount, the GST Amount, and the Gross Amount.

Formulas Used

• Adding GST:**
  • GST Amount = Net Amount * (GST Rate / 100)
  • Gross Amount = Net Amount + GST Amount = Net Amount * (1 + (GST Rate / 100))
• Removing GST:**
  • Net Amount = Gross Amount / (1 + (GST Rate / 100))
  • GST Amount = Gross Amount - Net Amount
