Invoice Creator

Free tool

Sales tax calculator

Work out net, tax and gross totals when your rate is known. Use exclusive mode to add tax, or inclusive mode to reverse out tax from a quoted total.

Rates vary by country, state and product type. This calculator does not look up live rates and is not tax advice. Confirm the rate your registration requires before you invoice.

Result

Net (before tax)
1,000.00
Tax
82.50
Gross (with tax)
1,082.50

Transfer these figures into your invoice line items or tax field in the invoice generator.

Exclusive vs inclusive amounts

Exclusive means your line items are before tax: the calculator adds tax on top. Inclusive means the figure you typed already contains tax: the calculator splits net and tax.

Important limitations

  • We do not look up live state or national rates.
  • Some goods and services are zero-rated or exempt. This tool cannot decide that.
  • Country-specific invoice rules (NTN, TRN, VAT numbers) belong on the invoice itself; see our tax invoice guide.

Apply it on a real invoice

When you know the rate, open the invoice generator, set the tax percentage on the form, and download a PDF that matches the live preview.
