VAT Calculator

This VAT calculator works for tax-inclusive and tax-exclusive pricing. It is useful when you need to back out tax from an invoice total or add tax to a quoted pre-tax amount.

Because pricing can be presented in different ways, a simple percentage calculation is often not enough. Inclusive pricing and exclusive pricing require different handling.

The result is presented as a clear breakdown so the tax component is transparent and easy to explain or audit.

Enter the amount and the tax rate.

Choose whether the amount entered is before tax or already tax inclusive.

Use the summary cards to see the net amount, tax portion, and total value clearly.

For tax-exclusive amounts, the tax is calculated directly as amount multiplied by the tax rate.

For tax-inclusive amounts, the calculator first derives the pre-tax amount by dividing by one plus the tax rate.

This keeps the tax breakdown internally consistent regardless of how the starting price is presented.

If a 1,000 price is before tax and the tax rate is 18%, the tax is added to reach the final total.

If a 1,450 price is tax inclusive, the calculator separates the embedded tax portion from the net amount.

Use the pre-tax amount when you need the net revenue or base transaction value.

Use the total amount when checking what the customer pays or what appears on a gross invoice.
