Key takeaways
- VAT & Sales Tax Calculator works both directions: add tax to a pre-tax price, or extract how much tax is already inside a tax-included price.
- Useful for invoicing, checking a receipt, or pricing a product for different tax regions.
- Enter whatever tax rate applies to you — the calculator doesn't assume a fixed rate, since VAT and sales tax vary by country and region.
Using it
Open VAT & Sales Tax Calculator and pick the direction:
- Add tax — enter a pre-tax price and rate, get the tax amount and total.
- Extract tax — enter a tax-included price and rate, get the pre-tax amount and the tax portion broken out.
Frequently asked questions
Does it know my country's tax rate automatically?
No — enter whatever rate applies to your region, since VAT and sales tax rates vary by country, and often by product category within a country.
Is this useful for invoicing?
Yes — many people use it alongside [Invoice Generator](/invoice-generator) to double-check tax figures on an invoice.
