How do I use the GST calculator?

Select your currency, choose 'Add GST' or 'Remove GST' mode, enter the amount (Net or Gross based on mode), and input the GST rate (or use a preset button). The results (Net Amount, GST Amount, Gross Amount) will update instantly.

What does 'Add GST' mode do?

In 'Add GST' mode, you enter the Net Amount (price before tax), and the calculator adds the specified GST percentage to show you the GST amount and the final Gross Amount (price including tax).

What does 'Remove GST' mode do?

In 'Remove GST' mode, you enter the Gross Amount (price including tax), and the calculator determines the original Net Amount (price before tax) and the amount of GST that was included in the total price.

Which countries' currencies are supported?

The calculator supports currencies commonly used in countries with GST, including INR (India), CAD (Canada), AUD (Australia), NZD (New Zealand), SGD (Singapore), and MYR (Malaysia). You can select your preferred currency from the dropdown menu.

Are the GST rates specific to my country?

The calculator provides common preset GST rates (like 5%, 12%, 18%, 28% often used in India, or others relevant to different regions). However, you can manually enter any GST rate applicable in your specific country or situation.
