How the Sales Tax Calculator Works

The tool supports two modes:

  1. Inclusive of Tax → Use this when the entered amount already includes tax.
  2. Exclusive of Tax → Use this when the entered amount does not include tax, and you need to add it.

For both options, you only need to enter:

  • Amount
  • Tax Percentage (%)

After clicking Calculate Tax, you will instantly see:

  • Net Amount (before tax)
  • Tax Rate
  • Gross Amount (with tax included)

Results are displayed in a user-friendly view, and you can copy each value individually with a simple click.
