VAT / Sales Tax Calculator
Whether you're pricing products for an online store, preparing invoices, or simply trying to figure out how much tax is included in a purchase, our VAT and Sales Tax Calculator makes it easy. Enter a price and tax rate to either add tax to a net price or extract the tax from a tax-inclusive price. The tool comes preloaded with standard VAT and sales tax rates for 28 countries and US states, so you can select your jurisdiction from a dropdown instead of looking up rates manually. It handles both Value Added Tax (VAT) used across Europe and most of the world, and sales tax as used in the United States, using the same straightforward percentage-based calculation.

How it works
The calculator operates in two modes, each using a different formula. When adding tax to a net price, it multiplies the net amount by the tax rate percentage and adds the result: Gross = Net × (1 + Rate/100). The tax amount is the difference between the gross and net values. This is the calculation you need when you know your pre-tax price and want to determine the final price a customer will pay.
When removing tax from a gross (tax-inclusive) price, the formula reverses: Net = Gross ÷ (1 + Rate/100). This is essential when you have a shelf price that already includes tax and need to determine the net amount and the tax component separately — a common requirement for accounting, bookkeeping, and invoice preparation.
The preset tax rates are organized by country and include standard national VAT rates for EU member states, the UK, Australia (GST), Canada (GST), Japan, and other major economies, as well as state-level sales tax rates for all US states that levy sales tax. You can also enter any custom rate manually, which is useful for local tax jurisdictions, reduced rates on specific goods, or special economic zones with non-standard rates.
